cluster displayPractical hints Car care Index Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in steering lock position 2.
It should go out with engine running.
See page208if the warning lamp lights up or flashes
when the vehicle is moving.
BAS / ESP malfunction indicator lamp
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The yellow BAS/ESP malfunction indicator
lamp in the instrument cluster comes on with the
electronic key in steering lock position 2. It should go
out with the engine running.
If the BAS/ESP malfunction indicator lamp remains
illuminated with the engine running, see page209
.ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in steering lock position 2 and
should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster remains illuminated
while the engine is running, it indicates that the ABS
has detected a malfunction and has switched off. In this
case, the brake system functions in the usual manner,
but without antilock assistance.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page206 for notes on the antilock brake system
(ABS).

and controlsOperation DrivingInstrument
cluster displayPractical hints Car care Index
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 269 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.
