bag is disabled. If the front-passenger seat is
recognized as empty, the air bag control unit
will not deploy the front-passenger air bag in
the event of a collision.
Ask your passenger to sit correctly on the
front-passenger seat in an upright position
until the 4/ indicator lamp goes out.
If the 4/ indicator lamp does not go
out, please consult an authorized Mercedes-
Benz Center. Driver's air bag
:deploys in front of the
steering wheel; front-passenger front air
bag ;deploys in front of and above the glove
box.
The front air bags increase protection for the
driver's and front-passenger's head, neck and
chest.
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 independently of other air bags in the
vehicle
R depending on whether the seat belt is being
used
If the vehicle rolls over, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in a longitudinal
direction, the front air bags are deployed.
Your vehicle is equipped with a dual-stage
driver's air bag and a single-stage front-
passenger front air bag. In the event of a
collision, the air bag control unit evaluates the vehicle deceleration. In the first deployment
stage, the driver's air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front-passenger front air bag, however, is
immediately filled with the maximum amount
of propellant gas. The driver's air bag is fully
deployed if a second deployment threshold is
exceeded within a few milliseconds.
The lighter the front passenger, the higher the
vehicle deceleration rate required (predicted
at the start of the impact) for triggering the
front-passenger front air bag.
The front air bags will not deploy in impacts
with vehicle deceleration or acceleration
rates which do not exceed the system’s
preset deployment thresholds for vehicle
deceleration or acceleration. You will then be
protected by the fastened seat belt.
Front-passenger front air bag ;will only
deploy if:
R the front-passenger seat is occupied
R the 45 indicator lamp on the center
console is not lit (Y page 44)
R the impact exceeds a preset deployment
threshold
The front-passenger air bag is automatically
activated and deactivated. Both driver and
passenger should always check whether the
front-passenger air bag is activated or
deactivated.
The deployment of the driver's air bag does
not mean that the front-passenger air bag will
also deploy. If the system recognizes that the
front-passenger seat is empty, the front-
passenger air bag does not deploy even if the
impact fulfills the criteria and the driver's air
bag has deployed.
If the system detects that the front-passenger
seat is occupied, the 45indicator
lamp lights up for approximately six seconds
if:
R you turn the SmartKey to position 1or 2in
the ignition lock.
R the engine is running and then you switch
it off. Occupant safety
43Safety Z

Observe the manufacturer's instructions
when installing special child restraint
systems. Your vehicle is equipped with a BabySmart™
system.
Special child restraint systems which are
compatible with BabySmart™ are necessary
for deactivating the front-passenger air bag.
When the special BabySmart™-compatible
child restraint system is installed correctly
and is recognized by the sensor system in the
front-passenger seat, the front-passenger air
bag is deactivated. In this case, 45
indicator lamp :lights up. If you have any
questions regarding the special BabySmart™-
compatible child restraint systems, consult
an authorized Mercedes-Benz Center.
If the SmartKey has been removed from the
ignition lock or is in position 0,45
indicator lamp :does not light up.
The system does not disable:
R the window curtain air bag
R the Emergency Tensioning Device
System self-test G
WARNING
Do not leave any switched on notebooks,
mobile phones, electronic tags (e.g. a ski
pass) or similar electronic devices on the
front-passenger seat. Signals emitted from
such devices can interfere with the
BabySmart™ air bag deactivation system.
Such interference can lead to the 45 indicator lamp not lighting up during the self-
test.
If the
+ SRS warning lamp and the
4/ indicator lamp light up
simultaneously in the instrument cluster, the
system is malfunctioning. The front-
passenger air bag could deploy without cause,
or may fail to deploy in the event of an
accident.
Have the system checked as soon as possible
at an authorized Mercedes-Benz Center.
The 45 indicator lamp lights up when
the SmartKey is turned to position 1or 2in
the ignition lock.
The 45 indicator lamp goes out after
approximately six seconds.
If the 45 indicator lamp does not light
up or is always lit, then the system is
malfunctioning. Have the BabySmart™
system checked at an authorized Mercedes-
Benz Center before transporting a child on
the front-passenger seat.
For further information, see "Problems with
air bag deactivation system" (Y page 47).46
Occupant safetySafety

!
If the co-driver's seat is unoccupied, do
not insert the belt tongue into the buckle of
the co-driver's seat. This may otherwise
lead to the triggering of the Emergency
Tensioning Device in the event of an
accident, which will then need to be
replaced.
X In order to ensure that the pyrotechnic
Emergency Tensioning Devices have not
been triggered, always have the seat belts
checked after an accident.
If the Emergency Tensioning Devices have
been triggered, they must be replaced.
The seat belts for the front seats and rear
outer seats are equipped with Emergency
Tensioning Devices and seat belt force
limiters.
The ETDs on the driver's and front-passenger
seat consist of pyrotechnic belt buckle
tensioners and belt anchor installation
tensioners that are triggered together. The
belt buckle tensioner is mounted on the B-
pillar and the belt anchor installation is
mounted on the side of the seat. After
deploying, both tensioners must always be
replaced.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
Seat belt force limiters, when activated, are
employed to help reduce the peak force
exerted by the seat belts on occupants during
a crash.
The front seat belt force limiters are
synchronized with the front air bags, which
take on a part of the deceleration force. Thus,
the force exerted on the occupant is
distributed over a greater area. The ETDs can only be activated when:
R
the SmartKey is in position 1or 2in the
ignition lock.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 40).
R the belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
The Emergency Tensioning Devices are
triggered depending on the type and severity
of an accident, if:
R in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R in the event of a side impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R in certain situations where the vehicle rolls
over, the system determines that it can
provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up. Children in the vehicle
