Warning and indicator lamps
Overview of indicator and warning lamps
Some systems will perform a self-test when the
v
ehicle is switched on. Some indicator and warn-
ing lamps may briey light up or ash. This behav-
iour is non-critical. These indicator and warning
lamps indicate a malfunction only if they light up
or ash aer the vehicle has been started or dur-
ing a journey.
