With the electronic key removed and the driver’s door 
open, a warning sounds and the message “SWITCH OFF 
LIGHTS” in the multifunction indicator appears if the 
vehicle’s exterior lamps (except standing lamps) are not 
switched off.
Fog lamps will operate with the parking lamps and/or 
the low beam headlamps on. Fog lamps should only be 
used in conjunction with low beam headlamps. Consult 
your State or Province Motor Vehicle Regulations 
regarding allowable lamp operation.
Fog lamps are automatically switched off when the 
exterior lamp switch is turned to position D.Daytime running lamps (Canada only)
When the engine is running and the selector lever is in 
a driving position, the low beam headlamps (includes 
parking lamps, side marker lamps, taillamps and 
license plate lamps) are automatically switched on.
When shifting from a driving position to position “N” 
or “P”, the low beam switches off (2 seconds delay).
For nighttime driving the exterior lamp switch should 
be turned to position B to permit activation of the 
high beam headlamps.
Night security illumination
When exiting the vehicle after driving with the exterior 
lamps on, they switch on again for added illumination 
for approximately 30 seconds after closing the last door. 
The lamp-on time period can be changed at your 
Mercedes-Benz Center.

To signal minor directional changes, such as changing 
lanes on a highway, move combination switch to the 
point of resistance only and hold it there.
To operate the turn signals continuously, move the 
combination switch past the point of resistance (up or 
down). The switch is automatically canceled when the 
steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signals fails, the turn signal indicator 
system flashes and sounds at a faster than normal rate.

LIGHTING SYSTEMWhen the message appears after starting the engine, or 
if it comes on while driving, this indicates a failure in 
the parking lamp, taillamp, stop lamp, or low beam 
headlamp. See page 280 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.
