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
interconnected, any modifications made
may produce an undesired effect on other
systems. Electronic malfunctions could seri-
ously impair the operating safety of your ve-
hicle.
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 to and impair the
operating safety of your vehicle. If you feel a
sudden strong vibration or ride disturbance,
or you suspect that damage to your vehicle
has occurred, you should turn on your haz-
ard 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 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.
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.

59 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
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
If you have selected the Comfort suspension
tuning (
page 231), the vehicle lowers
slightly when it is locked. You should there-
fore make sure that no one is standing near
the wheel arches or lying underneath the ve-
hicle when it is being locked. Otherwise,
personal injury could result.
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, or
damage to the vehicle drivetrain, as a result
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
wheel towards the road curb.
Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch, or press
KEYLESS-GO* start/stop button.
Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock vehicle
when leaving.
!
If you have selected the Comfort suspen-
sion tuning (
page 231), the vehicle lowers
slightly when you lock it within approximately
60 seconds after switching off the engine. When
parking, make sure that your vehicle cannot
come into contact with other objects, such as a
curb, while lowering. Your vehicle could
otherwise be damaged.
Warning!
G
Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to
lock up. You could lose control of the vehicle
and cause an accident. In addition, the vehi-
cle’s brake lights do not light up when the
parking brake is engaged.
60 Getting startedParking and locking1Release handle
2Parking brake pedal
Step firmly on parking brake pedal2.
When the engine is running, the warn-
ing lamp; (USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
Switching off headlamps
Turn the exterior lamp switch toM
(page 55).
For more information, see “Lighting”
(
page 128).
Turning off engine
Shift the automatic transmission to
positionP (
page 173).
Apply the parking brake (
page 59).
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
selector lever not fully engaged in positionP
is dangerous. Also, when parked on an in-
cline, positionP alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP.
When parked on an incline, turn front wheels
towards the road curb.i
Always set the parking brake in addition to
shifting to positionP (
page 173).
On slopes, turn the front wheels towards the
road curb.
95 Safety and Security
Driving safety systems
For more information, see the “Practical
hints” section (
page 343) and
(
page 361).Electronic traction system
The electronic traction system is a
component of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
Except CLS 63 AMG:
When you switch off the ESP
®, the
electronic traction system is still enabled.Switching off the ESP
®
Switching off the ESP
®
(except CLS 63 AMG)
To improve the vehicle’s traction, switch
off the ESP
® in driving situations where it
would be advantageous to have 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
!
Because the ESP
® operates automatically,
the engine and the 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 axle
raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!
G
If you are driving too fast, the electronic
traction system cannot reduce the risk of an
accident.
The electronic traction system cannot pre-
vent the natural laws of physics from acting
on the vehicle.
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 driving
maneuvers.
Do not switch off the ESP
® when a spare
wheel is mounted.

visual and audible alarm is triggered when
someone opens
a door
the trunk
the hood
The alarm will stay on, even if the activat-
ing element (a door, for example) is imme-
diately closed.
The alarm system will also be triggered
when
someone attempts to raise the vehicle
(only vehicles with tow-away alarm)
the vehicle is opened with the
mechanical key
someone opens a door from the inside
i
In case the engine cannot be started (yet the
vehicle’s battery is charged), the system is not
operational. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA), or
1-800-387-0100 (in Canada).
118 Controls in detailLocking and unlocking
Close the trunk (
page 113).
Remove the mechanical key from the
SmartKey (
page 396).
Insert the mechanical key in the trunk
lid lock.
Turn the mechanical key clockwise to
position2 to lock the trunk.
The trunk remains locked even when the
vehicle is centrally unlocked.
Insert the mechanical key in the trunk
lid lock.
Turn the mechanical key counterclock-
wise to neutral position1 to unlock the
trunk.
You can now open the trunk
(page 112).
Automatic central locking
The doors and the trunk automatically lock
when the ignition is switched on and the
wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km / h) or more.
The locking knobs in the doors move down.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
mode using the control system
(page 165).
Locking and unlocking from the inside
You can lock or unlock the doors and the
trunk from inside using the central locking
switch. This can be useful, for example, if
you want to lock the vehicle before starting
to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking switch.
i
You can only cancel the separate trunk lock-
ing mode by means of the mechanical key.
i
The doors are designed to unlock automati-
cally after an accident if the force of the impact
exceeds a preset threshold. The vehicle locks au-
tomatically when the ignition is switched on and
the wheels are turning at vehicle speeds of ap-
proximately 9 mph (15 km/h) or more. You could
therefore lock yourself out when the vehicle
is pushed or towed
is on a test stand
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. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
