Driver and front passenger front air bags 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 window curtain air
bags
The driver front air bag is designed to inflate
in two stages. This allows the driver front air
bag 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 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 front passenger seat is occupied
R the 4/ indicator lamp in the center
console is not lit ( Y page 37)
R the impact exceeds a preset deployment
threshold
The front passenger front air bag is activated
or deactivated automatically. Both the driver
and the front passenger should always use
the 4/ indicator lamp to check
whether the front passenger front air bag is
activated or deactivated.
Deployment of the driver front air bag does
not mean that the front passenger front air
bag also should have deployed. If the front
passenger seat have determined as being
empty the system suppresses deployment ofthe front passenger front air bag even though
the impact met the criteria and was of
sufficient severity to deploy the driver front
air bag.
When the front passenger seat is detected as
being occupied, the 4/ indicator lamp
will illuminate for approximately 6 seconds
when the SmartKey is in starter switch
position 1 or 2 or the engine is started and
then goes out, indicating that the front
passenger front air bag is activated.
Keep in mind that objects placed on the front
passenger seat may cause the system to
recognize the seat as occupied. This could
cause the front passenger front air bag to
deploy in a crash which exceeds the system’s
deployment threshold.
If the 4/ indicator lamp is illuminated,
the front passenger front air bag is
deactivated and will not be deployed.
If the 4/ indicator lamp is not
illuminated, the front passenger front air bag
is activated and will be deployed.GWarning!
Your vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle when
the system detects the front passenger seat
as empty.
If the 4/ indicator lamp illuminates
when an adult or someone larger than a small
individual is in the front passenger seat, the
front passenger front air bag is deactivated.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the front passenger seat is
detected as being empty.
Have the front passenger reposition himself
or herself in the seat until the 4/
indicator lamp goes out. If the 4/
indicator lamp does not go out, contact an
authorized Mercedes-Benz Center.

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.
RIf you must install a BabySmart™
compatible rear-facing child restraint on
the front passenger seat because
circumstances require you to do so, make
sure the 4/ indicator lamp is
illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 4/ indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 4/ indicator
lamp while driving to make sure the
4/ indicator lamp is illuminated. If
the 4/ 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.
RIf 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.
GWarning!
When using a BabySmart™ compatible child
seat on the front passenger seat, the front
passenger front air bag will not deploy only if
the 4/ indicator lamp remains
illuminated.
Please be sure to check the 4/
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the 4/
indicator lamp go out while the restraint is
installed, please check installation. If the
4/ indicator lamp remains out, do not
use the BabySmart™ restraint to transport a
child on the front passenger seat until the
system has been repaired.
Special BabySmart™ compatible child seats,
designed for use with the Mercedes-Benz
system, are required for use with the
BabySmart™ air bag deactivation system.
Please contact an authorized Mercedes-Benz
Center for information on availability. With
the special child seat installed properly, the
front passenger front air bag will not deploy.
4/ indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position 0.
The system does not deactivate the window
curtain air bag and the Emergency Tensioning
Device (ETD).
Self-test BabySmart™ without special
child seat installed
After turning the SmartKey in the starter
switch to position 1 or 2 the 4/
indicator lamp illuminates. If an adult
occupant is properly sitting on the front
passenger seat and the front passenger seat
is detected as being occupied, the

the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.GWarning!
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at a
time.
GWarning!
Damaged seat belts or seat belts that have
been subjected to stress in an accident must
be replaced. Also, the seat belt anchoring
points must be checked.
Only use seat belts which have been approved
by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate when
necessary.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Proper use of seat belts
GWarning!
USE SEAT BELTS PROPERLY
R Seat belts can only protect when used
properly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in case
of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, front passenger
front air bag, window curtain air bags for
door windows), Emergency Tensioning
Devices (ETDs) and seat belt force limiters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags
and ETDs) and side (window curtain air bags
and ETDs) impacts which exceed preset
deployment thresholds.
R Never wear the shoulder belt under your
arm, against your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R 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.40Occupant safetySafety and security

Seat and head restraintGObserve Safety notes, see page 65.XPosition the seat and head restraint
properly. See ( Y page 66) for seat and
head restraint adjustment.
Observe the following points:
R Always be in a properly seated position.
R The position should be as far rearward from
the front air bag in the steering wheel as
possible, while still permitting proper
operation of vehicle controls.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
R The seat must be adjusted so that you can
correctly fasten and position your seat belt.
R The seat backrest must be in a position that
is as nearly upright as possible.
R Adjust the seat cushion so that the front
edge of the seat cushion lightly supports
your legs.
R 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.
R Never place hands under the seat or near
any moving parts while the seat is being
adjusted.
Children in the vehicle
Safety notes
If an infant or child is traveling with you in the
vehicle:
XSecure the child using an infant or child
restraint appropriate to the age and size of
the child.XMake sure the infant or child is properly
secured at all times while the vehicle is in
motion.GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts.
GWarning!
Do not carry heavy or hard objects in the
passenger or cargo compartment unless they
are firmly secured in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident
