In the event of other types of impacts and

impacts below air bag deployment thresh-

olds, the air bags will not deploy. The driver

and passenger will then be protected to the

extent possible by a properly fastened seat

belt. A properly fastened seat belt is also nee-

ded to provide the best possible protection in

a rollover.
Air bags provide additional protection; they

are not, however, a substitute 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. This will help to make sure the air

bags continue to perform their protective

function for the vehicle occupants in the

event of a crash.

After an air bag has been deployed, have

the vehicle towed to the nearest qualified

specialist workshop, even if your vehicle is

ready to drive.

Front air bags

The front air bags increase protection for the

driver's and front passenger's head and

chest.

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.

They are deployed:

at the start of an accident with a high rate of

vehicle acceleration or deceleration in a

longitudinal direction

if the system determines that air bag

deployment can offer additional protection

to that provided by the seat belt

independently of other air bags in the vehi-

cle

The release time of the front air bags is

dependent upon the use of the seat belt.
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 has adaptive, two-stage front air

bags. In the event of a collision, the air bag

control unit evaluates the vehicle decelera-

tion. In the first deployment stage, the front

air bag is filled with enough propellant gas to

reduce the risk of injuries. The front air bag is

fully deployed if a second deployment thresh-

old is exceeded within a few milliseconds.
The deployment of 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) (

page 49).

The lighter the passenger-side occupant, the

higher the vehicle deceleration rate required

(predicted at the start of the impact) for sec-

ond stage inflation of the front-passenger

front air bag. In the second stage, the front air

bags are inflated with the maximum amount

of propellant gas available.
The front air bags are not deployed in situa-

tions where a low impact severity is predic-

ted. You will then be protected by the fas-

tened seat belt.
