cluster displayPractical hints Car care Index LIGHTING SYSTEMWhen the message appears after starting the engine, or
if it come on while driving, this indicates a failure in the
parking lamp, taillamp, stop lamp, or low beam
headlamp. See page 285 for instructions on replacing
bulbs.
If an exterior lamp fails, the message will appear only
when that lamp is switched on.
If a brake lamp fails, the message will appear when
applying the brake and stays on until the engine is
turned off.
Note:
If additional lighting is installed (e.g. auxiliary
headlamps etc.) be certain to connect into the fuse
before the failure indicator monitoring unit order to
avoid damaging the system.
