You will find a full overview of the instrument panel in the "At a glance" section more.

On vehicles with BlueTec® exhaust gas aftertreatment, the AdBlue® level is displayed together with the outside temperature in the display above the rev counter.

Outside temperature display

AdBlue® gauge

The AdBlue® level is shown by means of bar display next to the symbol. Two full bars represent ¼ of the tank's capacity.

If the last bar of the AdBlue® gauge flashes, the AdBlue® level in the tank has dropped to the AdBlue® reserve level.

If bar display is empty and the symbol flashes in the display, the AdBlue® tank is already empty. You must then refill immediately more.

If, when continuing the journey a limited distance, the engine diagnostic indicator lamp comes on in the instrument panel, the vehicle is being driven without AdBlue® and thus, without an operating permit.

Display in the speedometer

To set the time forward

Make sure that the display in the speedometer is showing the time.

Setting the minutes: set the minutes using button or .

Setting the hours: simultaneously press and hold buttons and for longer than three seconds.

Release the buttons and within three seconds set the hours using button or .

If you press and hold button or , the time values change continuously.

Have the control panel battery changed at least every eight years at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. You could otherwise damage the control panel when changing the battery.

If you do not have the battery changed in good time, the set time will be erased each time the ignition is switched off.

Outside temperature

You will find a full overview of the instrument panel in the "At a glance" section more.

Changes in outside temperature are displayed with a slight delay. This prevents an incorrect temperature display caused by heat from the engine when the vehicle is stationary or moving slowly.

WARNING

At temperatures just above freezing point, the street may be icy, especially in wooded areas or on bridges. If you do not adapt your driving style to the conditions, the vehicle could skid. For this reason, adapt your driving style and speed to the weather conditions.

Coolant temperature

You will find a full overview of the instrument panel in the "At a glance" section more.

If corrosion inhibitor and antifreeze are present in the correct concentration in the coolant, the coolant temperature will be between 70 °C and 95 °C .

If the coolant temperature display reaches 100 °C , only drive on for a short time, not more than 10 minutes. If the needle moves into the red area of the display, stop the vehicle as soon as possible, paying attention to road and traffic conditions. Engine damage could result from driving on.

Determine the cause. If necessary, have the fault checked and rectified as soon as possible at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

You will find information about the coolant level in the "Operation" section more.

Engine oil pressure

You will find a full overview of the instrument panel in the "At a glance" section more.

If the indicator lamp lights up in the instrument panel, the oil pressure is too low. Safe operation of the engine is then jeopardised.

Do not pull away or, if the vehicle is already in motion, stop as soon as possible, paying attention to road and traffic conditions, and then switch off the engine.

Determine the cause. If necessary, have the fault checked and rectified as soon as possible at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

On vehicles without BlueTec® exhaust gas aftertreatment, the engine oil pressure is displayed with the outside temperature in the display above the rev counter.

Outside temperature display

Engine oil pressure display

The engine oil pressure is indicated via bar display next to the icon, whereby one display bar corresponds to 1.0 bar in pressure.

After reaching the operating temperature of between 70 °C to 95 °C , the engine oil pressure can increase to 2.5 bar at rated engine speed and drop to 0.5 bar at idling speed.

Do not rev up the engine and do not pull away before the engine oil pressure is displayed. If the engine oil pressure reading does not appear after approximately 10 seconds, stop the engine immediately. There is otherwise a risk of engine damage.

Determine the cause. If necessary, have the fault checked and rectified as soon as possible at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

You will find information about the engine oil level in the "Operation" section more.

Brake circuit reservoir pressure

You will find a full overview of the instrument panel in the "At a glance" section more.

The brake system supply pressure is displayed separately for each brake circuit.

Supply pressure display, brake circuit 1

Supply pressure display, brake circuit 2

Brake pressure warning lamp

An adequate supply pressure in the individual pressure circuits of the brake system (at least 10 bar) is required for the safe operation of the vehicle. A supply pressure of at least 8.5 bar is only sufficient for vehicles with air suspension or a trailer coupling without BlueTec® exhaust gas aftertreatment. The auxiliary consumer circuit is only filled after brake circuits 1 and 2 have been filled.

The brake pressure warning lamp between the two displays comes on if the supply pressure in one brake circuit drops below 6.5 bar.

More pressure information on the compressed-air brake system can be found in the "Technical Data" section more.

WARNING

A leaking compressed-air brake system jeopardises the operating and road safety of the vehicle. If there is insufficient supply pressure in the compressed-air brake system, you will not be able to brake the vehicle. You could thereby cause an accident and endanger yourself and others.

Do not pull away, or if the vehicle is already in motion, stop as soon as possible, paying attention to road and traffic conditions if:

• the supply pressure in brake circuit 1 or 2 is below 6.5 bar and

• the brake pressure warning lamp between the displays for the supply pressure does not go out.

Have the brake system checked and repaired at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required.

Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. All work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.
