Front air bags
GObserve Safety notes, see page 37.
Driver’s front air bag : and front passenger
front air bag ; are designed to provide
increased protection for the driver and front
passenger against the risk of injuries to the
head and thorax.
Driver and front passenger front air bag and
driver’s side knee bag are deployed
Rin the event of certain frontal impacts
Rif the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
Rdepending on whether the respective seat
belt is in use
Rindependently of the side impact air bags
and/or the window curtain air bags
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.
Vehicles with OCS, USA only: The front
passenger front air bag deployment is
additionally influenced by the passenger’s
weight category as identified by the Occupant
Classification System (OCS) (Y page 42).
Vehicles with OCS, USA only: The lighter the
front passenger-side occupant, the higher the
vehicle deceleration rate required for second
stage inflation of the front passenger front air
bag.
The air bags will not deploy in impacts which
do not exceed the system’s preset
deployment thresholds. You will then be
protected by the fastened seat belts.
The front air bags will not deploy in the event
of a rollover unless the vehicle’s rate of
longitudinal deceleration or acceleration
exceeds the preset deployment threshold for
the front air bags.
The front passenger front air bag will only be
deployed if
Rvehicles with OCS, USA only: the system,
based on OCS weight sensor readings,
detects that the front passenger seat is
occupied
Rthe 42 indicator lamp in the
center console is not lit
(USA only: (Y page 42),
Canada only: (Y page 46))
Rthe impact exceeds a preset deployment
threshold
! 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.
Knee bag
Knee bag = is designed to provide increased
protection for the driver against the risk of
injuries to the knees, thighs and lower legs.
Knee bag = is located on the driver side
lower instrument panel. It is designed to
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

purpose when
Ryou engage the latch plate into the buckle
and then turn the SmartKey in the starter
switch to position 2
Rthe SmartKey in the starter switch is in
position 2 and you then engage the latch

The seat belt adjustment function takes place
with a certain amount of retracting force
when the system senses slack between the
vehicle occupant and the seat belt. Do not
retain the seat belt during this procedure. You
can activate or deactivate the seat belt
adjustment function via the control system
(Y page 139).
Releasing the seat beltsXPress seat belt release button ?
(Y page 50).
Allow the retractor to completely rewind
the seat belt by guiding latch plate ;
(Y page 50).
! Make sure the seat belt retracts
completely. Otherwise the seat belt and/or
latch plate could get caught or pinched in
the door or in the seat mechanism. This can
damage the seat belt and impair its
effectiveness, and/or cause damage to the
door and/or door trim panel. Such damage
is not covered by the Mercedes-Benz
Limited Warranty.
Damaged seat belts must be replaced.
Contact an authorized Mercedes-Benz
Center.
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale 7 will always illuminate for
6 seconds to remind you and your passengers
to fasten your seat belts.
If the driver’s seat belt is not fastened when
the engine is started, an additional warning
chime will sound. The warning chime goes out
after approximately 6 seconds or once the
driver’s seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened with
front doors closed,
Rthe seat belt telltale 7 remains
illuminated for as long as either the driver’s
or front passenger’s seat belt is not
fastened.
Rand if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a
maximum of 60 seconds or until the
driver’s and front passenger’s seat belt are
fastened.

The PRE-SAFE®
system takes preventive
measures to better protect the occupants
from the possibility of personal injuries in the
following hazardous situations:
R emergency braking maneuvers with the
Brake Assist System (BAS) ( Y page 63)
activated
R critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
PRE-SAFE ®
takes the following measures
when it is activated:
R The front seat belts are pre-tensioned
automatically.
R Vehicles with front passenger seat memory
function: If the passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
R If the vehicle is in a critical dynamic driving
situation, the door windows close, except
for a minimal gap that remains open.
R Vehicles with power tilt/sliding sunroof: If
the vehicle is in a critical dynamic driving
situation, the tilt/sliding sunroof also
closes, except for a minimal gap that
remains open.
If the closing procedure of any of these
elements is blocked, it will stop and open
slightly.
Once the hazardous situation no longer exists
and an accident has been avoided, the seat
belt pre-tensioning is deactivated. All of the
PRE-SAFE ®
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
the rear until the seat belt tension is
reduced.
The locking mechanism releases.! 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.

function as an integrated comfort feature of
PRE-SAFE ®
, 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 on the front seats are designed to
move forward 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 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.
Contact an authorized Mercedes-Benz Center
for availability.
When the NECK-PRO active front head
restraints have been triggered in an accident,

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 325).
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.
