Automatic transmission

Important safety notes

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

WARNING

If the engine speed is above the idling speed and you engage transmission position D or R, the vehicle could pull away suddenly. There is a risk of an accident.

When engaging transmission position D or R, always firmly depress the brake pedal and do not simultaneously accelerate.

Vehicles with automatic transmission may roll only briefly in the neutral position N. Prolonged rolling of the wheels, e.g. when being towed, will result in transmission damage.

Selector lever positions

Park position

This prevents the vehicle from rolling away when stopped. Only move the selector lever to P when the vehicle is stationary.

You can only remove the key in this selector lever position. The selector lever is locked in position P when the key is removed.

The parking lock should not be used as a brake when parking. Always apply the parking brake as well once you have parked the vehicle.

Reverse gear

Only move the selector lever to R when the vehicle is stationary.

mbsymb1a_inv_0041.png

Neutral

No power is transmitted from the engine to the drive wheels. Releasing the brakes will allow you to move the vehicle freely, e.g. by pushing or towing.

Do not move the selector lever to N while driving. The automatic transmission could otherwise be damaged.

If ASR is deactivated or ESPĀ® has malfunctioned: only move the selector lever to N if the vehicle is in danger of skidding, e.g. on icy roads.

Drive

The automatic transmission shifts gear of its own accord. All forward gears are available.

You can influence the gearshifts and shift gears yourself or limit the shift range.

Changing gear

The 5-speed automatic transmission adapts to your individual driving style by continuously adjusting its shift points. These shift point adjustments take into account the current operating and driving conditions. If the operating or driving conditions change, the automatic transmission reacts by adjusting the gearshift program.

When the selector lever is in position D, the automatic transmission selects the individual gears automatically. This depends on:

  • whether the shift range is restricted or not more

  • the position of the accelerator pedal

  • the road speed

Touchshift

When the selector lever is in position D, you can perform gearshifts yourself.

To shift down: press the selector lever to the left towards D- .

The automatic transmission shifts to the next gear down, depending on the gear currently engaged. The shift range is also restricted.

The automatic transmission does not shift down if you press the selector lever towards D- while travelling at too high a speed. This protects against engine overspeed.

To shift up: briefly press the selector lever to the right towards D+ .

The automatic transmission shifts to the next gear up, depending on the current gearshift program. This also extends the shift range.

To derestrict the shift range: press and hold the selector lever towards D+ until D appears in the display again.

The automatic transmission shifts from the current shift range directly to D.

To select the optimum shift range: press and hold the selector lever to the left towards D- .

The automatic transmission will shift to a range which allows easy acceleration and deceleration. To do this, the automatic transmission will shift down one or more gears.

Shift ranges

When the selector lever is in position D you can restrict or derestrict the shift range for the automatic transmission.

To extend/restrict the shift range: press the selector lever briefly to the right towards D+ or left towards D- .

The display shows the selected shift range. The automatic transmission shifts only as far as the relevant gear.

If the maximum engine speed for the restricted shift range is reached and you continue to depress the accelerator pedal, the automatic transmission will not shift up.

Driving situations

mbsymb1a_inv_0035.png

Use the braking effect of the engine on downhill gradients and for driving:

  • on steep mountain roads

  • in mountainous terrain

  • in arduous conditions

mbsymb1a_inv_0034.png

Use the braking effect of the engine on extremely steep downhill gradients and long downhill stretches.

Driving tips

Accelerator pedal position

Your style of driving influences how the automatic transmission shifts gear:

  • little throttle: early upshifts

  • lots of throttle: later upshifts

Kickdown

Use kickdown for maximum acceleration:

Depress the accelerator pedal beyond the pressure point.

The automatic transmission shifts to the next gear down, depending on the engine speed.

Ease off on the accelerator pedal once the desired speed is reached.

The automatic transmission shifts up again.

Manoeuvring

Manoeuvring in a tight space:

Control the vehicle's speed by braking carefully.

Depress the accelerator pedal slightly and evenly.

Trailer towing

Use a moderate engine speed on uphill gradients.

Depending on the uphill or downhill gradient, shift down to a shift range suited to the driving situation more, even if cruise control is switched on.

Problems with the transmission

Problem

Possible causes/consequences and > Solutions

The transmission malfunctions when shifting gear.

The transmission is losing oil.

Have the transmission checked immediately at a qualified specialist workshop.

The acceleration characteristics have deteriorated noticeably.

The transmission does not shift.

The transmission is in emergency mode.

It is only possible to shift into second gear or reverse gear R.

Stop the vehicle.

Depress the brake pedal.

Move the selector lever to position P.

Switch off the engine.

Wait at least 10 seconds before restarting the engine.

Depress the brake pedal.

Move the selector lever to position D or R.

In position D, the transmission shifts into second gear; in position R, the transmission shifts into reverse gear.

Have the transmission checked immediately at a qualified specialist workshop.

Releasing the parking lock manually

images/img9151fbae351f15146f45e27a83f90f6e_1_--_--_JPG72.jpg

Apply the parking brake.

Remove cover mbsymb6_inv_003a.png using a suitable object, e.g. a screwdriver, and pull the leather cover up sharply.

Push implement mbsymb6_inv_003d.png downwards and simultaneously move the selector lever out of position P.

The selector lever lock is released. You can now move the selector lever freely again until it is returned to position P.

In the event of a malfunction, it is possible to manually release the selector lever from the lock in parking position P, e.g. to have the vehicle towed away.
