Warning and indicator lamps
Overview of indicator and warning lamps
Some systems will perform a self-test when the vehicle is switched on. Some
indicator and warning lamps may briefly light up or flash. This behaviour is
non-critical. These indicator and warning lamps indicate a malfunction only if
they light up or flash after the vehicle has been started or during a journey.
The indicator and warning lamps are located in the highlighted display sec‐
tions.
