Front air bags
G
Observe 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 bags are
deployed
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the respective seat
belt is in use
R independently 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
R
vehicles with OCS, USA only: the system,
based on OCS weight sensor readings,
detects that the front passenger seat is
occupied
R the 42 indicator lamp in the
center console is not lit
(USA only: (Y page 42),
Canada only: ( Y page 45))
R the 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.
Side impact air bags G
Observe Safety notes, see page 37. G
Warning!
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 40

R
regardless of whether the seat belt on the
impacted side of the vehicle is in use
R in certain vehicle rollovers, if the system
determines that air bag deployment can
offer
additional protection to that provided
by the seat belt
Window curtain air bags : are not deployed
in impacts which do not exceed the system’s
deployment threshold.
Window curtain air bags : deploy in the area
indicated by the arrows. Occupant Classification System
The
Occupant Classification System (OCS) is
standard equipment in USA.
The OCS activates or deactivates the front
passenger front air bag automatically. The
respective status is based on the classified
occupant weight category determined by
weight sensor readings from the front
passenger seat.
The system does not deactivate
R the front passenger side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices (ETDs)
To be classified correctly, the front passenger
must sit
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between the
seat and middle console or the seat and door,
other passengers pushing on the seat, or objects applying pressure to the back of the
seat. Always make sure the seat has
clearance in all directions at all times.
If your seat, including the trim cover and
cushion,

needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 42 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 42 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 42 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 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated. 42

In order to ensure proper operation of the air
bag system and OCS:
R
Do not place more than 4.4 lb
(2 kg) into
the parcel net on the back of the front
passenger seat. Otherwise, the OCS may
not be able to properly approximate the
occupant weight category.
R Do not place objects under and/or around
the front passenger seat.
R Do not hang anything from or attach any
items to the seats.
R Do not stuff objects such as books between
the front passenger seat and the center
console or front passenger door.
R Do not move the front passenger seat
backwards against stiff objects.
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 While seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result in
the OCS being unable to correctly
approximate the occupant’s weight
category.
R Read and observe all warnings in this
chapter.
OCS Self-test After turning the SmartKey in the starter
switch to position 1 or 2 or pressing the
KEYLESS-GO start/stop button once or
twice, the 42 indicator lamp
illuminates. If an adult occupant is properly
sitting on the front passenger seat and the
system classifies the occupant as an adult,
the 42 indicator lamp will
illuminate and go out after approximately
6 seconds.
If the seat is not occupied and the system
classifies the front passenger seat as being empty, the 42 indicator lamp
will illuminate and not go out. G
Warning!
If the 42
indicator lamp does not
illuminate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
For more information, see the “Practical
hints” section ( Y page 307). G
Warning!
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the

effectiveness of the OCS. The bottom and
back of the child seat must make full contact
with the passenger seat cushion and
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats. BabySmart™ air bag deactivation
system
The

BabySmart™ air bag deactivation system
is standard equipment in Canada. G
Warning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children

be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child. Occupant safety
