Operator’s Manual. Ignoring them could
result in damage to the vehicle or personal
injury to you or others. Vehicle damage
caused by failure to follow instructions is not
covered by the Mercedes-Benz Limited
Warranty.
We continuously strive to improve our
product and ask for your understanding that
we reserve the right to make changes in
design and equipment. Therefore,
information, illustrations, and descriptions in
this Operator’s Manual might differ from your
vehicle.

operate together with the driver front air bag
in certain frontal impacts if the system
determines that air bag deployment can offer
additional protection to that provided by the
seat belt. Knee bag = operates best in
conjunction with a properly positioned and
fastened seat belt.
Side impact air bags
GObserve Safety notes, see page 37.GWarning!
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
Improper repair work on the doors or the
modification or addition of components to the
doors create a risk of rendering the side
impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Center.
Front side impact air bags : and rear side
impact air bags ; are designed to provide
increased protection for the thorax but not
the head, neck and arms.
The side impact air bags are deployed
Ron the impacted side of the vehicle
Rin instances with a high rate of lateral
vehicle deceleration or acceleration
Rregardless of whether the seat belts on the
impacted side of the vehicle are in use
Rindependently of the front air bags
Rindependently of the ETDs
Vehicles with OCS (USA only): The front
passenger side impact air bag will not deploy
if the OCS senses that the front passenger
seat is empty and the front passenger seat
belt is not fastened. With the front passenger
seat empty and the seat belt fastened, the
front passenger side impact air bag will
deploy independently of the empty seat.
Whether a seat belt is recognized as fastened
depends on whether or not the latch plate is
properly inserted into the buckle.
The side impact air bags are not deployed in
side impacts which do not exceed the
system’s deployment threshold.
The side impact air bags will not deploy in the
event of a rollover unless the vehicle’s rate of
lateral deceleration or acceleration exceeds
the preset deployment threshold for the side
impact air bags.
! Vehicles with BabySmart™ air bag
deactivation system (Canada only): Do not
place objects heavier than 20 lb (9 kg) on
the front passenger seat. This could cause
the front or side impact air bag on the front
passenger side to deploy in a crash which
exceeds the system’s deployment
threshold.
GWarning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags and/or pelvis air
bags. Contact an authorized Mercedes-Benz
Center for availability.

interfere with or prevent the deployment of
the side impact air bags and/or pelvis air
bags. Contact an authorized Mercedes-Benz
Center for availability.

tension and decreases the air pressure in the
air pockets of the drive-dynamic multicontour

system
settings can be re-adjusted following the
critical driving event.
If the seat belts do not release:XAdjust the seat backrest or seat slightly to

! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items.

the PRE-SAFE ®
system, see ( Y page 51).
NECK-PRO active front head
restraints
The NECK-PRO active front head restraints
are intended to offer the driver and front
passenger increased protection from
whiplash-type injuries. In the event of a rear-
end collision, the NECK-PRO active front head
restraints are designed to move forward and
up in the direction of travel. They thus provide
the head with increased support earlier on in
the collision sequence. The NECK-PRO active
front head restraints will move forward and
up whether the seats are occupied or not.
GWarning!
Do not attach any objects (e.g. hangers) to the
head restraint posts. Otherwise, the NECK-
PRO active front head restraints may not be
able to function properly or offer the intended
degree of protection they were designed for
in the event of a rear-end collision.
GWarning!
Only use seat or head restraint covers which
have been tested and approved by Mercedes-
Benz for your vehicle model.
Using other seat or head restraint covers may
interfere with or prevent the activation of the
NECK-PRO active front head restraints and/
or the deployment of the front side impact air
bags or pelvis air bags.
Contact an authorized Mercedes-Benz Center
for availability.
When the NECK-PRO active front head
restraints have been triggered in an accident,
the NECK-PRO active front head restraints
must be reset. Otherwise, the NECK-PRO
active front head restraints cannot offer any
additional protection in the event of another
rear-end collision.
For information on resetting the activated
NECK-PRO active front head restraints, see
“Resetting activated head restraints”
( Y page 316).
You cannot remove the NECK-PRO active
front head restraints.GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.
For information on head restraint adjustment,
see “Head restraint height” ( Y page 89), or
see “Head restraint fore and aft adjustment”
( Y page 89).

iIn 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.
Safety notesGWarning!
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 to 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.
ABSGObserve Safety notes, see page 62.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
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
XKeep continuous full pressure on the brake
pedal.62Driving safety systemsSafety and security
