Only in the event of such
asituation, will the
air bags provide their supplemental protec-
tion.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible
for the air bags to provide their supplemental
protection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air
bags will not deploy.T he driver and passenger
will then be protected to the extent possible
by ap roperly fastened seat belt. Aproperly
fastened seat belt is also needed to provide
the best possiblep rotection inarollover.
Air bags provide additional protection; they
are not, however, asubstitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced and to have any malfunctioning air bags
repaired.T his will help to make sure the air
bags continue to provide supplemental crash
protection for occupants.
Front air bags Driver's air bag
0043deploysinf ront of the
steering wheel; front-passenger front air
bag 0044deploysinf ront of and above the glove
box.
The front air bags increase protection for the driver's and front-passenger's head 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 depending on whether the seat belt is being
used
R independently of other air bags in the vehi-
cle
If the vehicle rolls over, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in alongitudinal
direction, the front air bags are deployed.
Your vehicle has adaptive, two-stage front air bags. In the event of acollision, the air bag
control unit evaluates the vehicle decelera-
tion. When the first deployment threshold is
reached, the front air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front air bag is fully deployed if asecond
deployment threshold is exceeded within a
few milliseconds.
The deployment of the front-passenger front
air bag is also influenced by the weight cate-
gory of the front passenger, which is deter-
mined by the Occupant Classification System
(OCS) (Y page 42).
The front air bags are not deployed in situa-
tions where alow impact severity is pre-
dicted. You will then be protected by the fas-
tened seat belt.
The front-passenger front air bag will only be deployed if:
R the Occupant Classification System (OCS)
has detected that the front-passenger seat
is occupied
R the 00730074 indicator lamp on the center
console is not lit
R the air bag control unit predicts ahigh-
impact severity 40

front-passenger front ai rbag and the front-
passenger knee ba gare deactivate dauto-
matically for certain weight categories. The
00730074 indicator lamp shows yo uthe cur-
rent status. If the 00730074indicator lamp
lights up ,the front-passenger front ai rbag

Occupant safetySafety

To be classified correctly, the frontp
assenger
must sit:
R with the seat belt fastened correctly
R in ap osition that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by lean-
ing on armrests), OCS may not be able to
approximate the occupant's weight category.
In order to determin ewhether or not the front
passenger has been detected, both the driver and the frontp assenger should observe the
00730074 indicator lamp.
If the front-passenger seat, the seat cover or the seat cushion are damaged, have the nec- essary repair work carried out at an author-
ized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz. G
WARNING
If the 00730074 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or alarger person, ask the passenger to
reposition themselves on the seat so that the
00730074 indicator lamp goes out.
In the event of acollision, the air bag control
unit will not allow front-passenger fronta ir
bag and front-passenger knee bag deploy-
ment when the OCS has classified the front-
passenger occupant as weighing as much as
or less than atypical 12-month-old child in a
standard child restraint or if the front-
passenger seat is classified as being unoccu-
pied.
If OCS has detected that the frontp assenger
weighs the same as or less than atypical 12-
month-old child in astandard child restraint
system, the 00730074indicator lamp lights
up when the engine is started and remains lit. This indicates that the front-passenger front
air bag is deactivated.
If OCS determines that the front-passenger
seat is unoccupied, the 00730074indicator lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger fronta
ir bag and front-
passenger knee bag are deactivated.
If OCS determines that the frontp assenger
weighs more than atypical 12 montho ld child
in as tandard child restraint system and clas-
sifies this as asmall person (e.g. ateenager or
small adult), the 00730074indicator lamp
lights up for approximately 6seconds when
the engine is started. Dependin gonoccupant
weight sensor readings from the seat, it will
then remain illuminated or go out. If the
00730074 indicator lamp is illuminated, the
front-passenger fronta ir bag is deactivated.
With the 00730074 indicator lamp out, the
front-passenger fronta ir bag and front-
passenger knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person, the 00730074 indicator lamp lights up for
approximately 6seconds when the engine is
started and then goes out. This shows that the
front-passenger fronta ir bag and front-
passenger knee bag are activated.
If the 00730074 indicator lamp is illuminated,
the front-passenger fronta ir bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 00730074 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
R in the event of certain frontal impacts
R if the impact exceeds apreset deployment
threshold
R independently of the other air bags
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the frontp assenger's weight category as
determined by the OCS
