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.

56 Getting startedParking and lockingYou 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 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 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.


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


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

57 Getting started
Parking and locking
Parking brake
1Parking brake
2Release handle
Step firmly on parking brake1.
When the engine is running, the indica-
tor lamp;(USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
Switching off headlamps
Turn the exterior lamp switch to posi-
tion M (
page 51).
For more information, see “Exterior lamp
switch” (
page 123).
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. 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 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 167).
When parked on an incline, also turn front
wheels towards the road curb.

83 Safety and Security
Driving safety systems
For more information, see the
“Practical hints” section (
page 324).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


in sand or gravelWhen you switch off the ESP


the ESP does not stabilize the vehicle


the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip


the traction control will still brake a
spinning wheel


the ESP continues to operate when you
are braking


you cannot activate Distronic*
!Because of the ESP’s automatic opera-
tion, the engine must be shut off
(SmartKey in starter switch position 0
or 1 or KEYLESS-GO* start/stop but-
ton in position 0 or 1) 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.
The ESP will only function properly if
you use wheels of the recommended
tire size (
page 422).
Warning!
G
ESP should not be switched off during nor-
mal driving other than in the circumstances
described below. Disabling of the system
will reduce vehicle stability in standard driv-
ing maneuvers.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.
iWhen the ESP is switched off and one
or more drive wheels are spinning, the
ABS/ESP warning lamp v in the
speedometer flashes. However, the
ESP will then not stabilize the vehicle.

85 Safety and Security
Driving safety systems
SBC brake system
The SBC brake system combines a hydrau-
lic brake circuit with electronically con-
trolled brake servo assistance. You have
increased braking safety and improved
braking comfort.Warning!
G
Never ignore a brake malfunction indicated
in the speedometer display, for example by
the;(USA only) or3(Canada only)
indicator lamp. Refer to the “Practical hints”
section (
page 326). Also read and ob-
serve the messages in the instrument clus-
ter multifunction display (
page 347).
Warning!
G
The SBC brake system requires electrical
power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 326)
comes on and warning messages
(
page 347) appear in the multifunction
display while driving. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased!
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
up to 30 miles (50 km) and at a speed not to
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 408).
