Cruise control

Important safety notes

Observe the notes on braking in the "Driving tips" section more.

If you fail to adapt your driving style or if you are inattentive, cruise control can neither reduce the risk of an accident nor override the laws of physics. Cruise control cannot take road, weather and traffic conditions into account. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time.

Do not use cruise control:

  • in traffic conditions that are unsuitable for driving at a constant speed, e.g. in heavy traffic, on winding roads or off-road

  • on slippery roads. Braking or accelerating may cause the drive wheels to lose traction and the vehicle could then skid.

  • when there is poor visibility, e.g. due to fog, heavy rain or snow

If there is a change of drivers, make sure that you inform the new driver about the set cruise speed.

General notes

Cruise control maintains the speed of the vehicle for you.

Use cruise control if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can set any speed from 30 km/h upwards in increments of 1 km/h.

../../../../global/pictures_mb/symb_info.png

If you have set mph as the units for the digital speedometer more, you can set any speed from 20 mph upwards in increments of 1 mph.

../../../../global/pictures_mb/symb_info.png

Cruise control should not be activated when driving off-road or on construction sites.

Cruise control may not be able to maintain the stored speed on uphill or downhill gradients. If the gradient evens out and the vehicle's speed does not fall below 30 km/h, the stored speed is resumed.

../../../../global/pictures_mb/symb_info.png

Gearshift indicator for vehicles with manual transmission:

  • always drive at an adequate, but not excessive engine speed

  • change gear in good time, particularly on steep uphill gradients

  • do not change down several gears at a time

  • gently depress the accelerator pedal after changing gear. This improves the smoothness of the gear change.

  • cruise control is deactivated if you depress the clutch pedal for longer than 6 seconds

  • if you shift into neutral and release the clutch pedal, the engine speed may increase considerably. Deactivate cruise control beforehand.

  • if the gear lever is in neutral after the clutch pedal is depressed, the engine speed may rise

  • LIM indicator lamp lit: variable SPEEDTRONIC is selected.

Activation conditions

To activate cruise control, all of the following activation conditions must be fulfilled:

  • the cruise control function must be selected more

  • the parking brake must be released. The mbsymb1a_inv_0063.png indicator lamp in the instrument cluster is off

  • you are driving faster than 30 km/h

  • neither the brake or clutch pedal is depressed

../../../../global/pictures_mb/symb_info.png

Other drive and brake systems not described in these Operating Instructions may affect cruise control. You can find information on this in the separate operating instructions provided by the body manufacturer.

Storing and maintaining the current speed

Accelerate the vehicle to the desired speed above 30 km/h.

Briefly push the cruise control lever up mbsymb6_inv_003a.png or down mbsymb6_inv_003d.png.

Release the accelerator pedal.

Cruise control is activated. The current speed is stored.

Resuming the stored speed

../../../../global/pictures_mb/symb_achtung.png

WARNING

If you call up a stored speed and this is different from the current speed, the vehicle accelerates or brakes. If you do not know what the stored speed is, the vehicle may accelerate or brake unexpectedly. There is a risk of an accident.

Take the traffic conditions into account before calling up the stored speed. If you do not know what the stored speed is, store the desired speed again.

Briefly pull the cruise control lever towards you mbsymb6_inv_003b.png.

Release the accelerator pedal.

Cruise control is activated and adjusts the vehicle's speed to the last speed stored.

When you pull the cruise control level towards you for the first time after starting the engine, cruise control adopts the current speed.

Setting the speed

It may be a moment before the vehicle starts to accelerate or brake to the set speed. Take this delay into account when setting the speed.

Briefly push the cruise control lever upwards mbsymb6_inv_003a.png to increase the speed or downwards mbsymb6_inv_003d.png to reduce the speed.

The last speed stored is increased/reduced in increments of 1 km/h.

or

Press and hold the cruise control lever up mbsymb6_inv_003a.png or down mbsymb6_inv_003d.png until the desired speed has been reached.

Release the cruise control lever.

The current speed is stored.

../../../../global/pictures_mb/symb_info.png

Cruise control is not deactivated if you depress the accelerator pedal. If you accelerate briefly to overtake, for example, cruise control adjusts the vehicle's speed to the last speed stored after you have finished overtaking.

Deactivating cruise control

There are various ways to deactivate cruise control:

Briefly press the cruise control lever forwards mbsymb6_inv_0041.png.

or

Apply the brakes.

or

Briefly push the cruise control lever in the direction of arrow mbsymb6_inv_003f.png.

Variable SPEEDTRONIC is selected. LIM indicator lamp mbsymb6_inv_0042.png in the cruise control lever lights up.

The last speed set remains stored. The last speed stored is cleared when you switch off the engine.

Cruise control is deactivated automatically when:

  • you apply the brakes

  • you apply the parking brake and the mbsymb1a_inv_0063.png indicator lamp in the instrument cluster lights up

  • you are driving slower than 30 km/h

  • you depress the clutch pedal for longer than 6 seconds while the vehicle is in motion

  • you shift the manual transmission to neutral while the vehicle is in motion and release the clutch pedal

  • you shift the automatic transmission to neutral position N while the vehicle is in motion

  • ESP® or ASR intervenes

  • there is a malfunction in the ESP® or ABS system.

Problems with cruise control

On vehicles with steering-wheel buttons, the speed cannot be set when cruise control is activated.

The display is showing a message of high priority and cannot therefore show a change in speed.

Proceed as instructed by the message in the display.

Deactivate cruise control

SPEEDTRONIC

Important safety notes

Observe the notes on braking in the "Driving tips" section more.

If you fail to adapt your driving style or if you are inattentive, SPEEDTRONIC can neither reduce the risk of an accident nor override the laws of physics. SPEEDTRONIC cannot take road, weather and traffic conditions into account. SPEEDTRONIC is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time.

If there is a change of drivers, make sure that you inform the new driver about the set cruise speed.

General notes

SPEEDTRONIC helps you to avoid exceeding a set speed.

You can set a variable or permanent speed limitation:

  • variable, for speed restrictions, e.g. in built-up areas

  • permanent, for long-term speed restrictions, e.g. when driving on winter tyres more

When the engine is running, you can use the cruise control lever to store any speed above 30 km/h as the speed limitation, even if the vehicle is stationary. You can adjust the speed limitation in increments of 1 km/h and 10 km/h.

../../../../global/pictures_mb/symb_info.png

If you have set mph as the unit for the digital speedometer more, you can set any speed above 20 mph as the speed limitation. You can adjust the speed limitation in increments of 1 mph and 5 mph.

../../../../global/pictures_mb/symb_info.png

The speed shown in the speedometer may differ slightly from the stored speed limitation.

You can only exceed the speed limitation stored by variable SPEEDTRONIC if you:

  • deactivate variable SPEEDTRONIC using the cruise control lever.

  • depress the accelerator pedal beyond the pressure point (kickdown with automatic transmission). The speed at which you are currently driving must not deviate from the stored speed limitation by more than 20 km/h. Variable SPEEDTRONIC is deactivated automatically.

../../../../global/pictures_mb/symb_info.png

You cannot deactivate variable SPEEDTRONIC by braking.

Displaying the speed limiter

Vehicles with steering wheel buttons:

After switching on and when setting the speed limitation, the Speed limit message and the stored speed are shown in the upper part of the display for approximately 5 seconds. The stored speed is then shown highlighted in the lower section of the display.

Vehicles without steering wheel buttons:

You will see the ... LIM km/h message and the stored speed in the display more.

../../../../global/pictures_mb/symb_info.png

When you call up or change the stored speed, the display flashes if your current speed is higher than the stored value.

The speed limitation may be exceeded on downhill gradients even if variable SPEEDTRONIC is activated.

If the vehicle exceeds the set speed limitation, the ... Speed limit km/h or ... LIM km/h message is displayed and the stored speed flashes in the display. If the vehicle continues to accelerate, a warning tone also sounds three times.

On vehicles with steering wheel buttons, the Limit ... km/h exceeded message is then displayed for approximately 5 seconds.

Brake manually if necessary.

Deactivating variable SPEEDTRONIC

There are various ways to deactivate variable SPEEDTRONIC:

Briefly press the cruise control lever forwards mbsymb6_inv_0041.png.

or

Briefly press the cruise control lever in the direction of arrow mbsymb6_inv_003f.png.

LIM indicator lamp mbsymb6_inv_0042.png in the cruise control lever goes out. Variable SPEEDTRONIC is deactivated and cruise control is preselected.

The last speed limitation set remains stored. The last speed limitation stored is deleted when you switch off the engine.

Variable SPEEDTRONIC is deactivated automatically if:

  • on vehicles with manual transmission, you shift to a higher gear and as a result the engine speed is too low.

  • you depress the accelerator pedal beyond the pressure point (kickdown with automatic transmission). The speed at which you are currently driving must not deviate from the stored speed limitation by more than 20 km/h.

  • there is a malfunction in the ESP® or ABS system

Permanent SPEEDTRONIC

General notes
../../../../global/pictures_mb/symb_info.png

Permanent SPEEDTRONIC is only available in certain countries.

The speed can be permanently limited to a value between 160 km/h (e.g. for driving on winter tyres) and 190 km/h or 210 km/h for:

  • vehicles without steering wheel buttons - at a qualified specialist workshop

  • vehicles with steering wheel buttons - by using the on-board computer when the vehicle is stationary more

Permanent SPEEDTRONIC remains active even if variable SPEEDTRONIC is deactivated.

../../../../global/pictures_mb/symb_info.png

If there is a malfunction in the ESP® or ABS system, permanent SPEEDTRONIC is deactivated for the duration of the malfunction.

You cannot then exceed the set speed limitation even if you depress the accelerator pedal beyond the pressure point (kickdown for automatic transmissions).

If you accelerate the vehicle using the accelerator pedal, the Speed limit Winter tyres ... km/h or ... LIM km/h message is shown shortly before the set speed limitation is reached.

Permanent SPEEDTRONIC controls the speed and the vehicle stops accelerating. You should then ease off the accelerator pedal accordingly.

The speed limitation may be exceeded on downhill gradients even if variable SPEEDTRONIC is activated.

If the vehicle exceeds the set speed limitation, the Speed limit Winter tyres ... km/h exceeded or the ... LIM km/h message is displayed and the stored speed flashes in the display. If the vehicle continues to accelerate, a warning tone also sounds three times.

On vehicles with steering wheel buttons, the Speed limit Winter tyres ... km/h exceeded message is shown for approximately 5 seconds.

Brake manually if necessary.

Electronic level control (ENR)

Important safety notes

../../../../global/pictures_mb/symb_achtung.png

WARNING

People's limbs may become trapped if they are located underneath the vehicle or between the vehicle body and the tyres when the vehicle is lowering. There is a danger of injury.

When lowering the vehicle, make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches.

../../../../global/pictures_mb/symb_achtung.png

WARNING

If you park a vehicle with pneumatic suspension and leave the ignition switched on, the pneumatic suspension remains active. If you then raise the vehicle using the jack, the pneumatic suspension attempts to compensate the vehicle level. The jack could tip over. There is a danger of injury.

Remove the key from the ignition lock before raising the vehicle. This prevents automatic readjustment of the vehicle level.

../../../../global/pictures_mb/symb_achtung.png

WARNING

When driving at a raised vehicle level, the driving characteristics may be significantly affected by the vehicle's raised centre of gravity. The vehicle may be more liable to tip when cornering, for example. There is a risk of an accident.

Always select as low a vehicle level as possible and adjust your driving style accordingly.

../../../../global/pictures_mb/symb_achtung.png

WARNING

If ENR is malfunctioning, the vehicle level may be asymmetrical, too high or too low. The driving and steering characteristics of the vehicle may be noticeably different. There is a risk of an accident.

Drive carefully and adapt your driving style to the changed driving characteristics or stop the vehicle, paying attention to road and traffic conditions. Contact a qualified specialist workshop.

../../../../global/pictures_mb/symb_ruf.png

If ENR is malfunctioning or making readjustments while the vehicle is moving, the vehicle level may be lowered. In this case, pay attention to the road conditions and make sure there is sufficient ground clearance. Drive on carefully. The chassis could otherwise be damaged.

If the mbsymb1a_inv_00ac.png indicator lamp lights up in the instrument cluster while you are driving more or the ENR not activated more message appears in the display, ENR is malfunctioning.

If the mbsymb1a_inv_00ac.png indicator lamp flashes rapidly in the instrument cluster while you are driving or the ENR Warning! Vehicle height message appears in the display, the vehicle level is too high or too low. The vehicle driving and steering characteristics are changed noticeably. ENR adjusts the vehicle level to the normal level as soon as possible. Continue to drive on carefully until the mbsymb1a_inv_00ac.png indicator lamp goes out or the display message disappears. Only then is the vehicle at normal level.

The level of the vehicle depends on vehicle load and the load distribution. On vehicles with an air-sprung rear axle, ENR compensates the level between front and rear axle automatically. The vehicle level is always maintained at the normal level, regardless of vehicle load. Driving dynamics remain unaffected.

Automatic mode can be deactivated when the vehicle is stationary and the vehicle level can be raised or lowered manually, e.g. for loading/unloading. When working on the vehicle or changing a wheel, you can deactivate ENR.

If you drive at speeds of 2 km/h or more, automatic mode and ENR are reactivated automatically.

../../../../global/pictures_mb/symb_info.png

If you switch off the ignition while the vehicle is stationary and have opened the tailgate/rear door, ENR remains active for about 45 seconds.

If the ENR compressor threatens to overheat, e.g. due to repeated raising or lowering within a short period, ENR is automatically deactivated (play protection). You can raise or lower the vehicle again after approximately 1 minute.

Problems with ENR

Problem

Possible causes/consequences and > Solutions

You cannot raise or lower the level of the vehicle when stationary.

The indicator lamp in the mbsymb1a_inv_00ac.png button is off.

The compressor threatens to overheat. After repeated raising and lowering of the vehicle, ENR is deactivated by the play protection feature.

After approximately 1 minute, attempt to set the vehicle level again manually.

ENR is deactivated due to undervoltage. The battery may not be charging.

Handling and ride comfort may suffer.

Start the engine.

Consult a qualified specialist workshop as soon as possible.

All-wheel-drive

../../../../global/pictures_mb/symb_ruf.png

A function or performance test should only be carried out on a twin-axle dynamometer. Before you operate the vehicle on such a dynamometer, please consult a qualified workshop. You could otherwise damage the drive train or the brake system.

../../../../global/pictures_mb/symb_ruf.png

Never tow the vehicle with one axle raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz implied warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground.

You can find information about changing a wheel in the "Breakdown assistance" section more.

If you fail to adapt your driving style or if you are inattentive, the permanent 4x4 all-wheel drive can neither reduce the risk of an accident nor override the laws of physics. The 4x4 all-wheel drive system cannot take road, weather and traffic conditions into account. The 4x4 all-wheel drive system is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time.

The 4x4 all-wheel drive system provides permanent drive to all four wheels. If a driven wheel spins due to lack of traction, the all-wheel drive system improves the traction of your vehicle in conjunction with ESP® and 4ETS.

If a driven wheel spins due to lack of traction:

  • When pulling away, only depress the accelerator pedal as far as required.

  • While driving, slowly take your foot off the accelerator pedal

Use winter tyres (M+S tyres), with snow chains if necessary, when the conditions are wintry more. This is the only way to get the full benefit from the all-wheel drive system.

You will find information on driving on unpaved surfaces in the "Driving off-road" section more.

PARKTRONIC

Important safety notes

PARKTRONIC is only an aid. It cannot replace your own awareness of the immediate surroundings. You are responsible for safe manoeuvring, parking and pulling away. When manoeuvring, parking and pulling away, make sure that there are no persons, animals or objects in the manoeuvring area.

PARKTRONIC does not account for obstacles that are:

  • beneath its detection range, e.g. persons, animals or objects

  • above its detection range, e.g. overhanging loads, overhangs or truck loading ramps

PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates the distance between your vehicle and an object visually and audibly.

Your vehicle features two separate sound emitters with different frequencies for the warning tones. The warning ranges in front of and behind the vehicle are indicated by different warning tones.

PARKTRONIC is automatically activated when the key is turned to position 2 in the ignition lock and the parking brake is released.

On vehicles with automatic transmission, you must also move the selector lever to position D, N or R.

PARKTRONIC is deactivated at speeds above 18 km/h. PARKTRONIC is reactivated at speeds below 16 km/h.

PARKTRONIC monitors the area around your vehicle with sensors in the front and rear bumpers.

Range of the sensors

../../../../global/pictures_mb/symb_ruf.png

Pay particular attention to obstacles above or below the sensors when parking, such as flower pots or trailer towbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or objects.

PARKTRONIC can suffer interference from:

  • ultrasonic sources such as a lorry's compressed-air brakes, an automatic car wash or a pneumatic drill

  • attachments to the vehicle, e.g. rear mounted racks

  • number plates (vehicle licence plates) that are not affixed flat against the bumper

  • dirty or icy sensors

images/img3b1fc79f9cdf9931351f191523c7d582_1_--_--_JPG72.jpg images/img89ed6b23e42d275f35477e6841a641a6_1_--_--_JPG72.jpg

The sensors must be free of dirt, ice or slush. Otherwise, they cannot function correctly. Clean the sensors regularly, taking care not to scratch or damage them more.

../../../../global/pictures_mb/symb_info.png

In the panel van, the warning displays for the rear of the vehicle are on the right and left-hand sides of the dashboard.

The warning displays show the distance between the sensor and the obstacle.

The warning display is divided into six yellow and two red segments for each side of the vehicle. When the first yellow segment lights up, PARKTRONIC is operational.

There is a malfunction if only the red segments of the warning display light up more.

The position of the gear lever or selector lever determines whether the front and/or rear area is monitored.

No areas activated

One or more segments light up as the vehicle approaches an obstacle, depending on the vehicle's distance from the obstacle.

From the first red segment onwards, you also hear a warning tone for approximately 2 seconds. This means that the vehicle's distance to the obstacle is about to fall below the minimum distance.

Roll-back warning

PARKTRONIC automatically monitors the area behind the vehicle if the vehicle begins to roll backwards without reverse gear engaged, e.g. after stopping on an uphill gradient.

If PARKTRONIC recognises an obstacle at a distance of at most 80 cm, all the segments in the warning displays light up. A continuous warning tone also sounds as the vehicle approaches the obstacle and for a further 2 seconds after the vehicle has come to a halt.

Deactivating/activating PARKTRONIC

images/img1355fc719cf0be9c351f19153af4543d_1_--_--_JPG72.jpg

Press the mbsymb1a_inv_0066.png button.

If PARKTRONIC is deactivated, the indicator lamp in the button lights up.

Trailer towing

PARKTRONIC is deactivated for the rear area when you establish an electrical connection between your vehicle and a trailer.

After uncoupling the trailer, unplug the 7-pin connector adapter from the socket more. Otherwise, PARKTRONIC remains deactivated for the rear area.

Remove a detachable trailer coupling if it is no longer required. PARKTRONIC measures the minimum detection range to an obstacle from the bumper, not the ball coupling.
