Display messages

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 display messages in the multi-function display are white, yellow or red. Red display messages have the highest priority.

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

Risk of accident

No further messages can be displayed if the instrument cluster and/or the multi-function display fails.

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 vehicle's handling characteristics may be affected. Adjust 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.

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.

  

Press or to hide the display message.

 

The on-board computer saves certain display messages. To call up display messages more.

Risk of accident and injury

The operating safety of your vehicle could be compromised if service work is carried out improperly. You could lose control of the vehicle, thereby causing an accident. Safety systems may also not be able to protect you or others as intended.

Always have maintenance 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.
