16 IntroductionOperating safety
Proper use of the vehicle
Proper use of the vehicle requires that you
are familiar with the following information
and rules:
the safety precautions in this manual
the “Technical data” section in this
manual
traffic rules and regulations
motor vehicle laws and safety stan-
dards
Warning!
G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could seri-
ously impair the operating safety of your
vehicle.
See an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore nev-
er turn off the engine while driving.
Warning!
G
Heavy blows against the vehicle underbody
or tires/wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
operating safety of your vehicle. If you feel a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires/wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Center
or other qualified maintenance or repair fa-
cility for further inspection or repairs.
Warning!
G
Various warning labels are attached to your
vehicle. These warning labels are intended
to make you and others aware of various
risks. You should not remove any of these
warning labels unless explicitly instructed to
do so by information on the label itself. Re-
moval of any of these labels may cause you
and others to be unaware of certain risks
which may result in an accident and/or per-
sonal injury.

57 Getting started
Parking and locking
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows:Warning!
G
With the engine not running, there is no
power assistance for the brake and the
steering systems. In this case, it is impor-
tant to keep in mind that a considerably
higher degree of effort is necessary to brake
and steer the vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.
Turn the SmartKey to starter switch
position0 and remove, or press
KEYLESS-GO* start/stop button
(page 35).
Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock vehicle
when leaving.
58 Getting startedParking and lockingParking brake
1Parking brake pedal
2Release handle
Step firmly on parking brake1.
When the engine is running, the indica-
tor lamp ; (USA only) or
3(Canada only) in the instrument
cluster will be illuminated.
Switching off headlamps
Turn the exterior lamp switch toM
(page 52).
For more information, see “Exterior lamp
switch” (page 125).
Turning off the engine
Place the gear selector lever in
positionP.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake and/or move the gear selec-
tor lever to positionP, either of which could
result in an accident and/or serious injury.Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 48).
When parked on an incline, turn front wheels
towards the road curb.iAlways set the parking brake in addi-
tion to shifting to position P.
On slopes, turn the front wheels to-
wards the curb.
83 Safety and Security
Driving safety systems
For more information, see “Practical hints”
(page 332).Switching off the ESP
®
To improve the vehicle’s traction, switch
off the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravel
Warning!
G
The 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
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP
® equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
iDistronic* is switched off when the
ESP
® engages.
iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 410).
!Because of the ESP’s
® automatic oper-
ation, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO*
start/stop button in position0 or1)
when
the parking brake is being tested on
a brake test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
®
may otherwise seriously damage the
brake system.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
iDistronic* cannot be activated when
the ESP
® has been switched off.

Tow-away alarm
Once the tow-away alarm is armed, a visual
and audible alarm will be triggered when
someone attempts to raise the vehicle.Arming tow-away alarm
Lock your vehicle with the SmartKey or
KEYLESS-GO*.
The tow-away alarm is automatically
armed after about 30 seconds.
Disarming tow-away alarm
To prevent triggering the tow-away alarm,
switch off the tow-away alarm feature be-
fore towing the vehicle, or when parking on
a surface subject to movement, such as a
ferry or auto train.
iThe tow-away protection alarm is trig-
gered, for example, if the vehicle is lift-
ed on one side.
If the alarm stays on for more than
30 seconds, a call to the Response
Center is initiated automatically by the
Tele Aid system (
page 241) provided
Tele Aid service was subscribed to and
properly activated, and that necessary
cellular service and GPS coverage are
available.
