70 Safety and SecurityOccupant safetyThe air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.The front passenger air bag will only be
deployed if:


the front passenger seat is occupied


the 75indicator lamp in
the center console is not lit
(page 76)


the impact exceeds a preset deploy-
ment threshold
Knee bag
The knee bag is located on the driver-side
lower instrument panel. It is designed to
operate together with the driver air bag in
certain frontal impacts exceeding a preset
threshold. The knee bag operates best in
conjunction with a properly positioned and
fastened seat belt.Side impact air bags, window curtain

i
The front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of vehicle deceleration as as-
sessed by the air bag control unit.
USA only:
On the front passenger side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 71).
USA only:
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.
!
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 passen-
ger side to deploy in a crash which exceeds the
system’s deployment threshold.

71 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are deployed:

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front air bags
In addition, the window curtain air bags2
are deployed:


in certain vehicle rollovers
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.Occupant Classification System
(USA only)
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category. Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all di-
rections at all times.
Both driver and the front passenger should
always use the 75 indicator
lamp as an indication of whether or not the
front passenger is properly positioned.i
The system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the Emergency Tensioning De-
vice.
i
If your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to your authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.

75 Safety and Security
Occupant safety
The 75 indicator lamp is lo-
cated in the center console.
1Indicator lamp
The 75 indicator lamp1 will
be illuminated, except with the SmartKey
removed or in starter switch position0
(page 38).
Warning!
G
If the 1indicator lamp and the
75 indicator lamp are lit at the
same time, there is a malfunction in the
Occupant Classification System. The front
passenger front air bag will be deactivated
in this case.
In order to ensure proper operation of the
air bag system and OCS:

Have the system checked as soon as
possible by qualified technicians.
Contact an authorized Mercedes-Benz
Center.


Do not place more than 4.4 lb (2 kg) into
the ruffled storage bag on the back of
the front passenger seat. Otherwise, the
OCS may not be able to properly approx-
imate the occupant weight category.


Do not place objects under and/or
around the front passenger seat.


Do not hang anything from or attach any
items to the seats.


Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.


Do not move the front passenger seat
backwards against stiff objects.


Sit properly belted in a nearly upright
position with your back against the seat
backrest.


Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.


Only have the seat repaired or replaced
by an authorized Mercedes-Benz
Center.


Read and observe all warnings in this
chapter.

After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 75 indicator lamp
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system sens-
es the occupant as being an adult, the
75 indicator lamp will illumi-
nate and go out after approximately
6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 75 indicator lamp
will illuminate and not go out. For more information, see the “Practical

If the 75 indicator lamp should
not illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.Warning!
G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat
must make full contact with the passenger
seat cushion. An incorrectly mounted child
seat could cause injuries to the child in case
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.

tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible child
seat on the front passenger seat, the front
passenger front air bag will not deploy only
if the 75indicator lamp re-
mains illuminated.
Please be sure to check the indicator every
time you use the special system child seat.
Should the indicator lamp go out while the
restraint is installed, please check installa-
tion. If the indicator lamp remains out, do
not use the BabySmart
TM restraint to trans-
port children on the front passenger seat un-
til the system has been repaired.
