R Do not lean your head or chest close to the
steering wheel or dashboard.
R Keep hands on the outside of the steering
wheel rim. Placing hands and arms inside
the rim can increase the risk and potential
severity of hand/arm injury when the driver
front air bag inflates.
R Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious injuries or death should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint, or
booster seat recommended for the size and
weight of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual. G
Warning!
Accident research shows that the safest place
for
children in an automobile is in a rear seat.
There is a possibility for a side impact air bag-
related injury if occupants, especially
children, are not properly seated or restrained
when next to a side impact air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their heads in the area of the
door
where the side impact air bag
inflates. This could result in
serious injuries or death should
the side impact air bag be
deployed.
(2) Always sit as upright as possible, wear
the seat belt properly and use
an appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for the
size and weight of the child. and
for children 12 years old and
under, use an appropriately sized
infant restraint, toddler restraint,
or booster seat recommended for
the size and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of these
guidelines,
it would be safer for your rear seat
occupants to have the rear mounted side
impact air bags deactivated, then
deactivation can be carried out upon your
written request at an authorized Mercedes-
Benz Center at an additional cost.
Please contact an authorized Mercedes-Benz
Center or call the Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes
(1-800-367-6372), or Customer Service (in
Canada) at 1-800-387-0100 for details.
Air bags are designed to deploy only in certain
R frontal impacts (front air bags and driver’s
side knee bag)
R side impacts (side impact and window
curtain air bags) if the system determines
the need for air bag deployment
R rollovers (window curtain air bags)
Only in the event of such a situation will they
provide their supplemental protection.
The driver and passengers should always
wear their seat belts. Otherwise it is not
possible for the air bags to provide their
supplemental protection. 38

R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS.

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 bag and
driver’s side knee bag 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 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.
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 41).
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 the system, based on OCS weight sensor
readings, detects that the front passenger
seat is occupied
R the 04 indicator lamp in the
center console is not lit (Y page 41)
R the impact exceeds a preset 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 40

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

Furthermore, 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 stuffed between the seat and
middle console
R objects stuffed between the seat and door
R other passengers pushing on the seat
R 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 04
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 04 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 04 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 04 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating 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
04 indicator lamp will illuminate

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. The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt
and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer’s instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 04
indicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 04
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the Occupant safety

04 indicator lamp while
driving to make sure the 04
indicator lamp is illuminated. If the
04 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R If you have to place a child in a forward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions. For
children larger than the typical 12-month-
old child, the front passenger front air bag
may or may not be activated.
Deployment of the driver front air bag does
not mean that the front passenger front air
bag also should have deployed.
The OCS may have determined
R that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both of which are instances
where the system suppresses deployment
of the front passenger front air bag even
though the impact met the criteria and was
of sufficient severity to deploy the driver
front air bag
R that the seat was occupied by a small
individual (such as a young teenager or a
small adult) or a child who weighs more
than the weight of a typical 12-month-old
child in a standard child restraint – both of
which are instances where the system may
suppress deployment of the front
passenger front air bag even though the
impact met the criteria and was of sufficient severity to deploy the driver front
air bag

Warning!
If the red SRS indicator lamp + in the
instrument cluster and the 04
indicator lamp are lit at the same time, there
is a malfunction in the OCS. The front
passenger front air bag will be deactivated in
this case. Have the system checked by
qualified technicians as soon as possible.
Contact an authorized Mercedes-Benz
Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
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 storage bag 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. 44

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 04 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 04 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 04 indicator lamp
will illuminate and not go out. G
Warning!
If the 04
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 260). 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. Seat belts
Safety notes The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in motion.

Warning!
Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly
restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat

Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
a crash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
R Pregnant women should also always use a
lap/shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R Place the seat backrest in a position that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R When using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer’s instructions. G
Warning!
Do not pass seat belts over sharp edges. They
could tear. Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
