The front air bags increase protection for the
driver's and front-passenger's head and
chest.
Driver's front air bag : deploys in front of
the steering wheel; front-passenger front air
bag ; deploys in front of and above the glove
box. They are deployed:
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other air bags in the
vehicle
If the vehicle overturns, the front air bags are
generally not deployed unless the system
detects high vehicle deceleration in a
longitudinal direction.
Your vehicle has adaptive, dual-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. When the first deployment
threshold is reached, the front air bag is filled
with enough gas to reduce the risk of injuries.
The front air bag is fully deployed if a second
deployment threshold is exceeded within a
few milliseconds.
Vehicles with OCS (USA only): front-
passenger front air bag deployment is also
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
passenger side occupant, the higher the
vehicle deceleration rate required for second
stage inflation of the front-passenger front air
bag. In the second stage, the front air bags
are inflated with the maximum amount of
propellant gas available.
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.
! Vehicles with BabySmart™ (Canada only):
do not place objects heavier than 20 lb
(9 kg) on the front-passenger seat, as this
could be interpreted as the seat being
occupied. In the event of an accident, the
restraint systems on the front-passenger
side are deployed. Have restraint systems
replaced that have been deployed.
The front-passenger front airbag will only
deploy if:
R the system, based on the OCS weight
sensor readings, detects that the front-
passenger seat is occupied (USA only).
R the 42 indicator lamp in the
center console is not lit, USA:
( Y page 42), Canada: ( Y page 48).
R the impact exceeds a preset deployment
threshold.
Driver's knee bagGWarning
Observe "Important safety instructions"
( Y page 38).

In addition, the occupant weight may appear
to increase or decrease due to the following:
R objects hanging on the seat
R objects lodged underneath the seat
R objects lodged between the seat and the
center console
R objects lodged between the seat and the
door
R other passengers exerting weight on the
seat
R objects applying pressure to the back of
the seat
Make sure that the seat always has clearance
in all directions.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories which have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should observe the 42 indicator
lamp to determine whether or not the front
passenger is positioned correctly.GWarning!
If the 4 2 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 4 2 indicator lamp goes out,
or check whether objects are caught under or
around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-month-
old child in a standard child restraint or if the
front passenger seat is classified as being
empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 4 2 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 4 2 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
4 2 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the 4
2 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 4 2 indicator lamp out,
the front passenger front air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 4 2 indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then goes out,
indicating that the front passenger front air
bag is activated.
If the 4 2 indicator lamp is
illuminated, the front passenger front air bag
is deactivated and will not be deployed.Occupant safety43SafetyBA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 43Z
