Driver’s front air bag
:
and front passenger
front air bag
;
are designed to provide
increased protection for the driver and front
passenger against the risk of injuries to the
head and thorax.
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 side impact air bags
and/or the window curtain air bags
The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags 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 front passenger front air bag deployment
is additionally influenced by the passenger’s
weight category as identified by the Occupant
Classification System (OCS) (
Y
page 45).
The lighter the front passenger-side
occupant, the higher the vehicle deceleration
rate required for second stage inflation of the
front passenger front air bag.
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 system, based on OCS weight sensor
readings, detects that the front passenger
seat is occupied
R
the
04
indicator lamp in the
center console is not lit (
Y
page 45)
R
the impact exceeds a preset deployment
threshold
Side impact air bags

Observe Safety notes, see page 41.
Front side impact air bags
:
and rear side
impact air bags
;
are designed to provide
increased protection for the thorax but not
the head, neck and arms.
The side impact air bags are deployed
R
on the impacted side of the vehicle
R
in instances with a high rate of lateral
vehicle deceleration or acceleration
R
regardless of whether the seat belts on the
impacted side of the vehicle are in use
R
independently of the front air bags
R
independently of the ETDs
The side impact air bags are not deployed in
side impacts which do not exceed the
system’s deployment threshold.
The side impact air bags will not deploy in the
event of a rollover unless the vehicle’s rate of
lateral deceleration or acceleration exceeds
