The Malfunction Ind icator Lamp (MIL) ¢'4 i n
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ign ition is switched on and goes o ut after
the engine starts and the idle has stabilized.
Th is indicates that the MIL is working proper­
l y.
If the light doe s not go out after the eng ine
is started, or illuminates wh ile you are driv­
ing, a ma lfunction may exist in the engine sys­
tem . If the light illuminates, the catalytic con ­
verter cou ld be damaged.

ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.

(D Tips
-The light sensor* for headlight control is
located in the rear view mirror mount.
You should therefore not apply any stick­
ers to the windshield in this area in order
to prevent malfunctions or failures.

ad justed
¢ page 42.
- When you switch off the ignition while
the vehicle's lights are turned on, a buz­
zer sounds as long as the driver's door is
open .
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display~
