to the wheels . Your vehicle could "creep " forward or backward.
When stopped , keep the brake pedal fully depressed and use
the parking brake if necessary to keep the vehicle from rolling.
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before sele cting a driving posi ­
tion.

If the electronic control unit registers a crash of medium severity,
the first s tage of the airbag deploys followed by the second stage at
a much later time in the crash sequence -regardless of whether the
safety be lt is being used or not . In higher severity crashes as regis ­
tered by the e lectronic control unit , both the first and second stages
deploy almost at the same time .
On the passenger side, regardless of sa fety belt use, the airbag w ill
be turned off if the weight on the passenger seat is less than the
a m ount program med in the e lectronic control unit . The front airbag
on the passenger side w ill also be turned off if one of the chi ld seats
that has been cer tified unde r Federal Motor Vehicle Safety Standard
208 has been recogni zed on the seat . The
PASSENGER AIR BAG OFF

More Important things to know about front
airbags
Fi g. 2 32 In fl ated front
airba gs
Safety be lts are important to he lp keep front seat occupants in the
proper seated position so tha t airbags can unfold properly and
provide supplementa l protection in a fronta l collision.
The front air bags are designed to provide addi tional p rotecti on for
the chest and face of the driver and the front seat passenger when :
• safety belts are worn properly ,
• the seats have been positioned so that the occupant is properly
seated as far as possi ble fr om the a irbag,
• and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye with grea t force , things
you have on your lap or have p laced on the seat cou ld become
dangerous projectiles , and be pushed into you if the airbag inflates .
When an airbag deploys, fine dus t is released . This is norma l and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powde r used to lubrica te the airbags as they d eploy . It could irri tate
skin .
I t is important to remember that while the supplemental airbag
system is designed to reduce the likel ihood of serious injuries, other
injuries, for example swelling , bruising and minor abrasions, can
a lso happen when ai rbags inflate . Airbags do no t pro tect the arms
