Indicator and warning lamps
Indicator and warning lamps on the instru‐
ment cluster
Some systems will perform a self-test when the
ignition is switched on. Some indicator and warn‐
ing lamps may briefly light up or flash. This
behavior is non-critical. These indicator and warn‐
ing lamps indicate a malfunction only if they light
up or flash after the engine has been started or
during a journey.
