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
standards
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
interconnected, any modifications made
may produce an undesired effect on other
systems. Electronic malfunctions could
seriously 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
never 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 to 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
vehicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Center
or other qualified maintenance or repair
facility 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.
Removal of any of these labels may cause
you and others to be unaware of certain
risks which may result in an accident and/or
personal injury.

55 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:
Parking brake
1Release handle
2Parking brake pedal
Step firmly on parking brake pedal2.
When the engine is running, the indica-
tor lamp ;(USA only)
or3(Canada only) in the instru-
ment cluster will be illuminated.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important 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.
Warning!
G
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore 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
wheel towards the road curb.


Turn the SmartKey to starter switch
position0 and remove, or press
start / stop button (vehicles with
KEYLESS-GO*).


Take the SmartKey or the SmartKey with
KEYLESS-GO* and lock vehicle when
leaving.

56 Getting startedParking and locking
Switching off headlamps
Turn the exterior lamp switch toM
(page 50).
For more information, see “Lighting”
(
page 124).
Turning off the engine 
Place the gear selector lever in
positionP.
Turning off the engine with the
SmartKey

Turn the SmartKey in the starter switch
(page 34) to position0 and remove
it.
The immobilizer is activated.
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 from positionP, either of which
could result in an accident and/or serious
personal 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 169).
When parked on an incline, turn front wheels
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP.
On slopes, turn the front wheels to-
wards the curb.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.

87 Safety and Security
Driving safety systems
For more information, see “Practical hints”
(page 353).Switching off the ESP
To improve the vehicle’s traction, turn 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:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


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
capabilities of an ESP equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.
!Because of the ESP’s automatic
operation, the engine must be shut off
when

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
iThe ESP will only function properly if
you use wheels of the recommended
tire size.
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.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.
