When an adult is seated in the front
passenger seat, if the PASSENGER
AIR BAG “OFF” indicator is on,
change Engine Start/Stop button to
the OFF position and ask the pas-
senger to sit properly (sitting upright
with the seat back in an upright posi-
tion, centered on the seat cushion
with their seat belt on, legs comfort-
ably extended and their feet on the
floor). Restart the engine and have
the person remain in that position.
This will allow the system to detect
the person and to enable the pas-
senger air bag. If the PASSENGER AIR BAG “OFF”
indicator is still on, ask the passen-
ger to move to the rear seat.
✽ ✽
NOTICE
The PASSENGER AIR BAG “OFF”
indicator illuminates for about 4 sec-
onds after Engine Start/Stop button
is turned to the ON position after the
engine is started. If the front passen-
ger seat is occupied, the occupant
detection sensor will then classify
the front passenger after several
more seconds.

Proper position
WARNING - “AIR BAG
OFF” light
Do not allow an adult passenger
to ride in the front seat when the
PASSENGER AIR BAG “OFF”
indicator is illuminated,
because the air bag will not
deploy in the event of a crash.
The driver must instruct the
passenger to reposition himself
in the seat. Failure to properly
position yourself may lead to air
bag deactivation resulting in air
bag non-deployment in a colli-
sion. If the PASSENGER AIR
BAG “OFF” indicator remains
illuminated after the passenger
repositions themselves proper-
ly and the car is restarted, it is
recommended that passenger
move to the rear seat because
the passenger's front air bag
will not deploy.

Side air bag
❈ The actual air bags in the vehicle may differ
from the illustration.
Your vehicle is equipped with a side
air bag in each front seat. The purpose of the air bag is to pro-
vide the vehicle's driver and/or the
front passenger with additional pro-
tection than that offered by the seat
belt alone.
The side air bags are designed to
deploy during certain side-impact
collisions, depending on the crash
severity, angle, speed and point of
impact. However, when side deploy-
ment threshold is satisfied at front-
impact, side air bags may deploy.
The side air bags may deploy on the side of the impact or on both sides.
The side and/or curtain air bags on both sides of the vehicle will deploy
if a rollover or possible rollover is
detected.
The side air bags are not designed to deploy in all side impact or
rollover situations.

OJF035040
WARNING- Unexpected
deployment
Avoid impact to the side impact
airbag sensor when Engine
Start/Stop button is ON to pre-
vent unexpected deployment of
the side air bag.
WARNING- No attaching objects
No objects (such as dash pad
cover, cellular phone holder,
cup holder, perfume or stickers)
should be placed over or near
the air bag modules on the
steering wheel, instrument
panel, windshield glass, and the
front passenger's panel above
the glove box. Such objects
could cause harm if the vehicle
is in a crash severe enough to
cause the air bags to deploy. Do
not place any objects over the
air bag or between the air bag
and yourself.
WARNING
Never place or insert any object
into any small opening near
side airbag labels attached to
the vehicle seats. When the air
bag deploys, the object may
affect the deployment and
result in unexpected accident or
bodily harm.
