Air bags
GWarning!
Air bags are designed to reduce the potential
of injury and fatality in certain
R frontal impacts (front air bags and knee
bags)
R side impacts (side impact air bags and head
air bags)
However, no system available today can
completely eliminate injuries and fatalities.
Deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither harmful
to your health, nor does it indicate a fire in the
vehicle. The dust might cause some
temporary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get fresh
air by opening a window or door.
GWarning!
To reduce the risk of injury when the front air
bags inflate, it is very important for the driver
and passenger to always be in a properly
seated position and to wear their seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body.
Since the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag as it
inflates with great force instantaneously:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R Move the driver’s seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver’s chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm) or more.
You should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R Do not lean your head or chest close to the
steering wheel or dashboard.
R Keep hands on the outside of the steering
wheel rim. Placing hands and arms inside
the rim can increase the risk and potential
severity of hand/arm injury when the driver
front air bag inflates.
R Adjust the passenger seat as far as possible
rearward from the dashboard when the
seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the head air
bag inflates. This could result in serious
injuries or death should the head air bag be
deployed. Always sit as upright as possible,
wear the seat belt properly and use an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safetyOccupant safety45Safety and securityBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 45Z
RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts.
RDo not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
RNo modifications of any kind may be made
to any components or wiring of the SRS.
RDo no change or remove any component or
part of the SRS.
RDo not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, passenger front air bag cover,
outboard sides of the seat backrests, door
trim panels, or door frame trims.
RDo not install additional electrical/
electronic equipment on or near SRS
components and wiring.
RKeep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
RAir bag system components will be hot after
an air bag has inflated. Do not touch them.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RImproper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
RFor your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
RGiven the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS.
Also refer them to the applicable section in
the Operator’s Manual.
Front air bags
GObserve Safety notes, see page 45.
Driver’s front air bag : and passenger front
air bag ; are designed to provide increased
protection for the driver and passenger
against the risk of injuries to the head and
thorax.

The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags to have different rates of inflation.
The rate of inflation is based on the vehicle
deceleration rate as assessed by the air bag
control unit.
The passenger front air bag deployment is
additionally influenced by the passenger’s

Exiting the vehicle in an emergency
If the vehicle lies on the roof after an accident,
the locks in the door hinges of the gullwing
doors are opened pyrotechnically. You will
hear a bang when this happens. Once the
locks were opened, the doors are pushed
outward. The door locks are released at the
same time. The SRS warning lamp 6
comes on.
i The hinge locks will be opened
pyrotechnically only when the vehicle has
come to rest on its roof and does not move
anymore.
The doors can then be moved by pulling on
the door handle from the inside or outside.
Children in the vehicle
Safety notes
If an infant or child is traveling with you in the
vehicle:
XSecure the child using an infant or child
restraint appropriate to the age and size of
the child.XMake sure the infant or child is properly
secured at all times while the vehicle is in
motion.GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts.
GWarning!
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.

Driving safety systems
Introduction
This section contains information about the
following driving safety systems:
R ABS ( Antilock Brake System)
R Adaptive Brake
R BAS ( Brake Assist System)
R EBP ( Electronic Brake Proportioning)
R ESC ( Electronic Stability Control)
R Trunk Wing
Safety notes
GWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance from other road users
and objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
i In winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
ABS
GObserve Safety notes, see page 61.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
XKeep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
Driving safety systems61Safety and securityBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 61Z
functions as a reminder to take extra care
while driving.
Emergency brake maneuverXKeep continuous full pressure on the brake
pedal.GWarning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
BAS
GObserve Safety notes, see page 61.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
GWarning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
ESC
GObserve Safety notes, see page 61.
The Electronic Stability Control (ESC) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESC recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESC works to stabilize the vehicle. The ESC is
especially useful while driving off and on wet
or slippery road surfaces. The ESC also
stabilizes the vehicle during braking and
steering maneuvers.
The ESC warning lamp ÷ in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is
running.GWarning!
Never switch off the ESC when you see the
ESC warning lamp ÷ flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESC cannot
prevent accidents resulting from excessive
speed.
! Because the ESC operates automatically,
the engine and ignition must be shut off
(KEYLESS-GO start/stop button in position
0 or 1, or SmartKey in starter switch
position 0 or 1) when the electronic parking
brake is being tested on a brake test
dynamometer or when the vehicle is being
towed with the rear axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.

! The ESC will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i The cruise control switches off
automatically when the ESC engages.
Electronic Traction System (ETS) GObserve Safety notes, see page 61.
The ETS (Electronic Traction System) is a
component of the ESC. The ETS improves the
vehicle’s ability to utilize available traction,
especially under slippery road conditions by
applying the brakes to a spinning wheel.
When you switch off the ESC, the ETS is still
enabled.
Switching ESC SPORT on or off
GWarning!
ESC SPORT should not be switched on during
normal driving.
Switching ESC SPORT on will result in the
following:
R no restriction to engine torque
R system-supported traction control is
limited
ESC SPORT is designed for driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch on ESC SPORT.
Do not switch on ESC SPORT when a spare
wheel is mounted.
To improve the vehicle’s traction, switch on
ESC SPORT. This allows the drive wheels to
spin and thus cut into surfaces for better grip,
for example
R when driving with snow chains
R in deep snow
R in sand or gravelGWarning!
Switch off ESC SPORT and switch on the ESC
immediately if the aforementioned
circumstances do not apply anymore.
Otherwise ESC SPORT will only stabilize the
vehicle to a limited extent when it is starting
to skid or a wheel is spinning.
When you switch on ESC SPORT
R the ESC stabilizes the vehicle only to a
limited extent
R the engine output is limited, but only to the
extent that allows the drive wheels to spin
and thus cut into surfaces for better grip
R the ETS will still apply the brakes to a
spinning wheel
R the ESC continues to operate when you are
braking hard
R the cruise control cannot be activated
R the cruise control switches off if activated
i When ESC SPORT is switched on and one
or more drive wheels are spinning, the ESC
warning lamp ÷ in the instrument
cluster flashes. However, the ESC will then
stabilize the vehicle only to a limited extent.
