Occupant safety
In addition, the window curtain air bags
2
are deployed in certain vehicle rollovers.
The front passenger side impact air bag
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy indepen-
dently of the empty seat.
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Seat belts
When the engine is started, the seat belt
telltale
<
illuminates for a maximum of
6 seconds and a warning chime sounds to
remind you and your passengers to fasten
your seat belts.
If after these 6 seconds, the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) are not fastened
with all doors closed,
앫
and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt
telltale
<
remains illuminated for as
long as either the driver’s or front
passenger’s seat belt is not fastened
앫
and the vehicle speed exceeds
15 mph (25 km/h), the seat belt
telltale
<
starts flashing and a
warning chime sounds with increasing
intensity until both the driver’s and
front passenger’s seat belt are fas-
tened, or for a maximum of 60 seconds
from the time the vehicle speed
exceeded 15 mph (25 km/h) if either
the driver’s or front passenger’s seat
belt remains unfastened.
If the driver’s or front passenger’s seat
belt remains unfastened after
60 seconds, the seat belt telltale
<
stops flashing and the warning chime
stops sounding. The seat belt
telltale
<
then continues to be illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt are
not fastened.
The seat belt telltale
<
will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.
