14 IntroductionOperating safety
Operating 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 modification made may
produce an undesired effect on other sys-
tems.
See your 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 or 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 or
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 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 la-
bels unless explicitly instructed to do so by
information on the label itself. Removal of
any of these labels may cause you and oth-
ers to be unaware of certain risks which may
result in an accident and/or personal injury.

47 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
1Brake lever
2Release button
Pull up brake lever1 firmly.
When the engine is running, the indica-
tor lamp; (USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
Warning!
G
Wait until the vehicle is stationary before re-
moving the key from the starter switch. The
vehicle cannot be steered when the key is
removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
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.


Pull up the brake lever firmly.


Move the selector lever to position
P
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the key to steering lock position
0
and remove.

48 Getting startedParking and locking
Switching off headlamps
Turn the exterior lamp switch toM
(page 43).
More information can be found in the
“Controls in detail” section (
page 83).
Turning off engine 
Place the gear selector lever in
positionP (manual transmission: first
or reverse gear).

Turn the key in the steering lock to
position0 (
page 29) and remove it.
The immobilizer is activated.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock and lock the vehi-
cle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehi-
cle. Children could release the parking
brake and/or move the gear selector lever
from positionP, either of which could result
in an accident and/or serious injury.
Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. 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 (manual transmission:
first or reverse gear).
When parked on an incline, turn front wheel
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP (manual
transmission: first or reverse gear).
On steep slopes, turn the front wheels
towards the road curb.

69 Safety and Security
Driving safety systems
For more information, see “Practical hints”
(page 199).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 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.
!Because of the ESP’s automatic opera-
tion, the engine must be shut off (key in
steering lock position0 or1) 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.
The ESP will only function properly if
you use wheels of the recommended
tire size (
page 269).
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.
