Automatic central locking
With the automatic central locking system activated, the 
doors and trunk are locked at vehicle speeds of 
approximately 9 mph (15 km / h) or more. The fuel filler 
flap remains unlocked.
The automatic central locking function can be switched 
on or off in the individual setting menu “VEHICLE” – 
“AUTOMATIC DOOR LOCK”, see page 121.
Notes:
If doors are unlocked with the central locking switch 
after activating the automatic central locking, and 
neither door is opened, then the doors remain unlocked 
even at vehicle speeds of approximately 9 mph
(15 km / h) or more.
If a door is opened from the inside at speeds of 
approximately 9 mph (15 km / h) or less with the 
automatic central locking activated, the door will again 
be automatically locked at speeds of approximately 
9 mph (15 km / h) or more.If a door is opened from the inside, the complete vehicle 
is unlocked, if the vehicle was previously centrally 
unlocked using the remote control.
Important!
When towing the vehicle, or with the vehicle on a 
dynamometer test stand, please, note the following:
With the automatic central locking activated and the 
electronic key in starter switch position 2, the vehicle 
doors will lock if the left front wheel as well as the right 
rear wheel spin at vehicle speeds of approximately 
9 mph (15 km / h) or more.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an 
accident in which an airbag or emergency tensioning 
retractor deploys (this is intended to aid rescue and 
exit).

Tow-away alarm (optional for Canada)
The switch is located in the center console.
1Press to switch off tow-away alarm
2Indicator lamp
Once the alarm system has been armed, the exterior 
vehicle lamps will flash and an alarm will sound when 
someone attempts to raise the vehicle.The alarm will last approximately 3 minutes in form of 
flashing exterior lamps. At the same time an alarm will 
sound for 30 seconds. The alarm will stay on even if the 
vehicle is immediately lowered. To cancel the alarm, 
insert the electronic key in the starter switch or press 
buttonŒ or‹ on the electronic key.
If the alarm stays on for more than 20 seconds, an 
emergency call is initiated automatically. See Tele Aid 
on page 228.
To pr even t tr igger in g t he tow-away alarm  feature,  switch 
off the tow-away alarm before towing the vehicle, or 
when parking on a surface subject to movement, such 
as a ferry or auto train.
To do so, turn electronic key in starter switch to 
position 0 or 1, or remove electronic key from starter 
switch. Press tow-away alarm switch (1). The indicator 
lamp (2) illuminates briefly.
Exit vehicle, and lock vehicle with the electronic key.
The tow-away alarm remains switched off until the 
vehicle is locked again with the electronic key, at which 
time it is automatically reactivated.

Interior Storage compartments and armrests
Wa r n i n g !
To help avoid personal injury during a collision or 
sudden maneuver, exercise care when stowing 
things. Put luggage or cargo in the trunk if 
possible. Do not pile luggage or cargo higher than 
the seat backs. Do not place anything on the 
luggage cover below the rear window.Luggage nets cannot secure hard or heavy objects. 
Wa r n i n g !
Keep compartment lids closed. This will help to 
prevent stored objects from being thrown about 
and injuring vehicle occupants during an accident. 

232 Tele Aid
Te ch n i c a l

Roadside Assistance button 
Located below the center armrest cover is the Roadside 
Assistance button. Pressing and holding the 
button (for longer than 2 seconds) will initiate a call to a 
Mercedes-Benz Roadside Assistance dispatcher. The 
button will flash while the call is in progress. The 
message “ROADSIDE ASSISTANCE – CONNECTING 
CALL” will appear in the multifunction display. When 
the connection is established, the message “ROADSIDE 
ASSISTANCE – CALL CONNECTED” appears in the 
multifunction display. The Tele Aid system will transmit 
data generating the vehicle identification number, 
model, color and location (subject to availability of 
cellular and GPS signals).A voice connection between the Roadside Assistance 
dispatcher and the occupants of the vehicle will be 
established. When a voice connection is established the 
audio system mutes and the message “TELE AID – 
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the 
multifunction display. The nature of the need for 
assistance can then be described. The Mercedes-Benz 
Roadside assistance dispatcher will either dispatch a 
qualified Mercedes-Benz technician or arrange to tow 
your vehicle to the nearest Mercedes-Benz Center. 
For services such as labor and/or towing charges may 
apply. Refer to the Roadside Assistance manual for more 
information.
These programs are only available in the USA:
•Sign and Drive services: Services such as jump start, 
a few gallons of fuel or the replacement of a flat tire 
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits 
the Mercedes-Benz Roadside Assistance dispatcher 
to download malfunction codes and actual vehicle 
data.
Wa r n i n g !
If you feel at any way in jeopardy when in the 
vehicle (e.g. smoke or fire in the vehicle, vehicle in 
a dangerous road location), please do not wait for 
voice contact after you have pressed the emergency 
button. Carefully leave the vehicle and move to a 
safe location. The Response Center will 
automatically contact local emergency officials 
with the vehicle’s approximate location if they 
receive an automatic “SOS” signal and cannot make 
voice contact with the vehicle occupants.

Electronic stability program (ESP)
The ESP enhances directional control and reduces 
driving wheel spin of the vehicle under various driving 
conditions.
Over/understeering of the vehicle is counteracted by 
applying brakes to the appropriate wheel to create a 
countervailing vehicle movement. Engine torque is also 
limited. The ESP warning lamp, located in the 
speedometer dial, starts to flash when ESP is in 
operation.Important!
If the ESP warning lampv flashes:
•During take-off apply as little throttle as possible.
•While driving ease up on the accelerator.
•Adapt your speed and driving to the prevailing road 
conditions.
•Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see 
page 341, “Towing the vehicle”), the engine must be 
shut off (electronic key in starter switch position 0 or 1). 
Otherwise, the ESP will immediately be engaged and 
will apply the rear wheel brakes.
Wa r n i n g !
ESP cannot prevent the natural laws of physics 
from acting on the vehicle, nor can it increase the 
traction afforded. The ESP cannot prevent 
accidents, including those resulting from excessive 
speed in turns, or aquaplaning. Only a safe, 
attentive, and skillful driver can prevent accidents. 
The capabilities of an ESP equipped vehicle must 
never be exploited in a reckless or dangerous 
manner which could jeopardize the user’s safety or 
the safety of others.

311 Fuses
Te ch n i c a l
data Instruments

cluster displayPractical hintsCar care Index Stowing things in the vehicle Fuses
Most of your vehicle’s electrical components are fused 
with safety fuses. With the exception of the brake lights, 
all individual lighting system components are 
electronically fused. Before replacing a blown safety 
fuse, determine the cause of the short circuit. Always 
observe amperage and color of fuse.
The circuit for components is protected by a cycled 
circuit breaker interrupted if too much current is being 
drawn. The circuit closes automatically after a short 
time; the circuit is broken again if the malfunction 
reoccurs.
Always use a new fuse for replacement. Never attempt to 
repair or bridge a blown fuse.
A fuse chart is located in fuse box (1).
A special fuse puller is located in the auxiliary fuse box 
in the trunk, see page 314.
Wa r n i n g !
To help avoid personal injury during a collision or 
sudden maneuver, exercise care when stowing 
things. Put luggage or cargo in the trunk if 
possible. Do not pile luggage or cargo higher than 
the seat backs. Do not place anything on the shelf 
below the rear window.
