Central locking system
Radio frequency and infrared remote control
The electronic main key has an integrated radio 
frequency and infrared remote control.
Due to the extended operational range of the remote 
control, it could be possible to unintentionally lock or 
unlock the vehicle by pressing the transmit button. If 
one of the transmit buttons is pressed, the battery check 
lamp lights up briefly – indicating that the batteries are 
in order. See page 283 for checking batteries.
The vehicle doors, trunk and fuel filler flap can be 
centrally locked and unlocked via remote control.
Opening and closing the windows and sliding/pop-up 
roof remotely can only be done with the infrared portion 
of the remote control. Aim transmitter eye at a 
receiver (6 or 7), press and hold transmit button Œ 
or ‹.
With vehicle centrally locked, the trunk can also be 
opened by using the remote control.
If the electronic key is inserted in steering lock, the 
vehicle cannot be locked or unlocked, and the trunk lid 
cannot be opened with the remote control.1Transmit button

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.

Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, posi tion “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set t he parki ng brake in addi tion to sh ifting 
to position “P”, see page 202 for parking brake. When parked on an incline, also turn front wheel 
against curb.Wa r n i n g !
When leaving the vehicle, always remove the 
electronic key from the steering lock, and lock the 
vehicle. Do not leave children unattended in the 
vehicle, or with access to an unlocked vehicle. 
Children could move the gear selector lever from 
position “P”, which could result in an accident or 
serious personal injury.

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 page 219 if the warning lamp lights up or f lashes 
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 page 215 for 
notes on the brake assist (BAS) and page 219 for notes 
on the electronic stability program (ESP).ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the 
instrument cluster comes on with the 
e l e c tr o n ic  key  i n  ste e ri n g  l oc k  p os i ti o n 2  a n d  
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  of f. Wh en t he voltage is a bove th is value a gain, 
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.

1. Position the vehicle with the charged battery so that 
the jumper cables will reach, but never let the 
vehicles touch. Make sure the jumper cables do not 
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories, 
except hazard warning f lashers or work lights.
•Apply parking brake and shift selector lever to 
position “P”.
Important!
3. Clamp one end of the first jumper cable to the 
positive (+) under hood terminal of the discharged 
battery and the other end to the positive (+) terminal 
of the charged battery. Make sure the cable clamps 
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the 
grounded negative (–) terminal of the charged 
battery and the final connection to the negative (–) 
terminal (2) of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery 
and run at high idle. Make sure the cables are not 
on or near pulleys, fans, or other parts that move 
when the engine is started. Allow the discharged 
battery to charge for a few minutes. Start engine of 
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables 
by exactly reversing the above installation 
sequence, starting with the last connection made 
first. When removing each clamp, make sure that it 
does not touch any other metal while the other end 
is still attached.
Notes:
If engine does not run after several unsuccessful 
starting attempts, have it checked at the nearest 
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic 
converter.
