cluster displayPractical hints Car care Index ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in starter switch 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.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Navigation,
Automatic transmission). Be guided accordingly with
respect to the use of those systems and have the system
checked at your authorized Mercedes-Benz Center as
soon as possible.With the ABS malfunctioning, the BAS and ESP are also
switched off. The malfunction indicator lamps and
malfunction messages in the multifunction display
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 of f. 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 page 276 for notes on antilock brake system (ABS).

ELEC. STABIL. PROG. (Electronic stability program)
* C = Category, see page 2931 The enhanced vehicle stability offered by ESP and the torque
reduction feature are unavailable.
2 This message may be displayed if the power supply was
interrupted (battery disconnected or empty). Synchronize ESP, see
page 279
3 The system is temporarily unavailable. The reason could be that
the self-diagnosis has not been completed. The display will clear
itself after driving a short distance at more than 12 mph
(2o km/h).
4 The system is unavailable due to low voltage, e.g. battery not being
charged.
5 A malfunction has been detected in the system. In case of ESP
malfunction the ESP warning lamp in the instrument cluster
illuminates and the ESP switch in the center console does not
function. If in addition the ABS is malfunctioning, only partial
engine output will be available.

Hood
Wa r n i n g !
To help prevent personal injury, stay clear of
moving parts when the hood is open and the engine
is running. Be sure the hood is properly closed
before driving. When closing hood, use extreme
caution not to catch hands or fingers.The radiator fan may continue to run for
approximately 30 seconds or even restart after the
engine has been turned off. Stay clear from fan
blades.If you see flames or smoke coming from the engine
compartment, or if the coolant temperature gauge
indicates that the engine is overheated, do not open
the hood. Move away from vehicle and do not open
the hood until the engine has cooled. If necessary,
call a fire department.
The engine is equipped with a transistorized
ignition system. Because of the high voltage it is
dangerous to touch any components (ignition coils,
spark plug sockets, diagnostic socket) of the
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned
manually.

Headlamp adjustment
Correct headlamp adjustment is extremely important.
Check and readjust headlamps at regular intervals and
when a bulb has been replaced.Replacing bulbs
Notes:
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
If the newly installed bulb does not light up, switch the
lamp off and on again. If the bulb still does not light up,
have the system checked at an authorized
Mercedes-Benz Center.
Wa r n i n g !
Bulbs and bulb holders can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
• scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.
