Antitheft alarm system
1Indicator lamp in switch located in center console
The antitheft alarm is automatically armed or disarmed 
with the remote control or the KEYLESS-GO-function, by 
locking or unlocking the vehicle.The antitheft alarm is armed within approx. 10 seconds 
after locking the vehicle with the remote control or the 
lock button at each door handle (vehicles with 
KEYLESS-GO).
A blinking lamp (1) indicates that the alarm is armed.
Operation:
Once the alarm system has been armed, the exterior 
vehicle lamps will flash and an alarm will sound when 
someone:
•opens a door,
•opens the trunk,
•opens the hood,
•attempts to raise the vehicle.
The alarm will last approximately 2
1/2minutes in form 
of f lashing exterior lamps. At the same time an alarm 
will sound for 30 seconds. The alarm will stay on even if 
the activating element (a door for example) is 
immediately closed. If the alarm stays on for more than 
20 seconds, an emergency call is initiated automatically. 
See Tele Aid on page 210.

cluster displayPractical hints Car care Index Coolant temperature gauge (5)
During severe operating conditions and stop-and-go city 
traffic, the coolant temperature may rise close to the red 
marking.
The engine should not be operated with the coolant 
temperature in the red zone. Doing so may cause 
serious engine damage which is not covered by the 
Mercedes-Benz Limited Warranty.Outside temperature indicator (6)
The temperature sensor is located in the front bumper 
area. Due to its location, the sensor can be affected by 
road or engine heat during idling or slow driving. This 
means that the accuracy of the displayed temperature 
can only be verified by comparison to a thermometer 
placed next to the sensor, not by comparison to external 
displays (e.g. bank signs etc.). 
Adaption to ambient temperature takes place in steps 
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of 
temperature change.
Note:
The temperature indicator display can be set to read out 
in either Fahrenheit or Celsius. See page 140.
Wa r n i n g !
• Driving when your engine is badly overheated 
can cause some fluids which may have leaked 
into the engine compartment to catch fire. You 
could be seriously burned.• Steam from an overheated engine can cause 
serious burns and can occur just by opening 
the engine hood. Stay away from the engine if 
you see or hear steam coming from it. Turn off 
the engine, get out of the vehicle and do not 
stand near the vehicle until it cools down.
Wa r n i n g !
The outside temperature indicator is not designed 
to serve as an Ice-Warning Device and is therefore 
unsuitable for that purpose. Indicated 
temperatures just above the freezing point do not 
guarantee that the road surface is free of ice.

1 This may indicate that the poly-V-belt has broken. Should this 
condition occur, the poly-V-belt must be replaced before continuing 
to operate the vehicle. Otherwise, the engine will overheat due to 
an inoperative water pump which may result in damage to the 
engine. Do not continue to drive the vehicle with this message 
displayed. Doing so could result in serious engine damage that is 
not covered by the Mercedes-Benz Limited Warranty.
2 The cooling fan for the coolant is faulty. Observe the coolant 
temperature gauge. See page 117
During severe operating conditions and stop-and-go city 
traffic, the coolant temperature may rise close to the red 
marking.
The engine should not be operated with the coolant 
temperature in the red zone. Doing so may cause

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.
