Important safety notes
G
WARNING
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems
no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
In this section, you will learn the most
important facts about the restraint system
components of the vehicle. 38
Occupant safety
Safety

If the
0073007C indicator lamp does not go
out, please consult an authorized Mercedes-
Benz Center. Driver's air bag
0043 deploys in front of the
steering wheel; front-passenger front air
bag 0044 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 0044 will only
deploy if:
R the front-passenger seat is occupied.
R the 00730074 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 00730074 indicator
lamp lights up for approximately six seconds
if:
R you turn the SmartKey to position 1 or 2 in
the ignition lock.
R the engine is running and then you switch
it off.
This indicates the operational readiness of
the front-passenger air bag.
Note that objects placed on the front-
passenger seat may cause the system to
recognize the seat as occupied. This can
result in the deployment of the front- Occupant safety
43
Safety Z

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, 00730074
indicator lamp 0043 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, 00730074
indicator lamp 0043 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 00730074
indicator lamp not lighting
up during the self-
test.
If the 007E SRS warning lamp and the
0073007C 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 00730074 indicator lamp lights up when
the SmartKey is turned to position 1 or 2 in
the ignition lock.
The 00730074 indicator lamp goes out after
approximately six seconds.
If the 00730074 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.

air bag deactivation system" ( Y page 47).46
