Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will switch off after a few seconds.

Failure to observe the warning lamps and text messages could lead to accidents and serious injuries.

• Never ignore any illuminated warning lamps or text messages.

NOTICE

Failure to observe illuminated indicator lamps and text messages can lead to your vehicle being damaged.

When the ACC is switched on, some ACC-related displays in the instrument cluster can be overwritten by other functions, incoming telephone calls for example.
