Notes

The on-board computer shows warnings or malfunctions in the multi-function display. Certain display messages are accompanied by a warning tone or a continuous tone.

The multi-function display shows high-priority display messages in red. In the following tables, these display messages are printed in red.

Please respond in accordance with the display messages and follow the additional notes in this Owner's Manual.

Risk of accident

If the instrument cluster or the multi-function display fails, no messages can be displayed.

This means that you will not see information about the driving situation, such as the speed, outside temperature, warning/indicator lamps, display messages or system failures. The handling characteristics may be affected. Adapt your driving style and speed accordingly.

Immediately consult 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. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

Before starting a journey, check that the warning and indicator lamps are operating correctly.

  

Turn the key to position 2 in the ignition lock.
or
  

Press the KEYLESS GO button* twice.
 

All warning and indicator lamps (except for the turn signal indicator lamps) light up and the multi-function display is activated.

The following tables contain all the display messages.

Hiding display messages

After a few seconds, the on-board computer automatically hides some low priority display messages. Other messages remain visible in the multi-function display until you hide them yourself.

Some high priority display messages cannot be hidden. The multi-function display shows these messages continuously until the causes of the messages have been remedied.

Use the buttons on the multi-function steering wheel.

  

Use the , , or button to select another display.
 

The on-board computer saves certain display messages in the message memory more.

Risk of accident and injury

The operating safety of your vehicle may be affected if service work is carried out incorrectly. There is a risk that you could lose control of the vehicle and cause an accident. The safety systems may also no longer be able to protect you or others as they are designed to do.

Always have service work carried out 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.

In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.
