When the vehicle is parked on the street the standing 
lamps (right or left side parking lamps) can be turned 
on, making the vehicle more visible to passing vehicles.
The standing lamps cannot be operated with the key in 
steering lock position 2.
Daytime running lamp mode
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 operate the turn signals continuously, move the

steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signal lamps fails, the turn signal 
indicator system flashes and sounds at a faster than 
normal rate.

Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index Charge indicator lamp
Should the charge indicator lamp fail to 
come on prior to starting when the key is in 
steering l ock position 2 or sh ou ld it fa il  to go 
out after starting or during operation, this indicates a 
malfunction which must be repaired immediately at an 
authorized Mercedes-Benz Center.
If the charge indicator lamp comes on, or a loss of power 
steering assistance is noticeable while the engine is 
running, this may indicate that one of the two poly-V-
belts has broken. Should this condition occur, the poly-
V-belt must be replaced before continuing to operate the 
vehicle. Otherwise, the engine may overheat due to an 
inoperative water pump which may result in damage to 
the engine.
Do not continue to drive the vehicle with the charge 
indicator lamp illuminated. Doing so could result in 
serious engine damage that is not covered by the 
Mercedes-Benz Limited Warranty.Exterior lamp failure indicator lamp
With the key in steering lock position 2, an 
indicator lamp comes on. It should go out 
when the engine is running.
If the warning lamp does not go out after starting the 
engine, or if it comes on while driving, this lamp 
indicates a failure in the parking lamp, taillamp, stop 
lamp, or low beam headlamp.
If a n exterior lamp fa ils, the indica tor lamp will com e on 
only when that lamp is switched on.
If a brake lamp fails, the lamp failure indicator will 
come on when applying the brake and stays on until the 
engine is turned off.
Note:
If additional lighting equipment is installed (e.g. 
auxiliary headlamps etc.) be certain to connect into the 
fuse before the failure indicator monitoring unit in 
order to avoid damaging the system.
