How The Airbag System Works
²
TheOccupant Restraint Controller (ORC)determines
if a frontal, side, or rollover collision is severe enough
to require the airbags to inflate. The front airbag
inflators are designed to provide different rates of
airbag inflation from direction provided by the ORC.
The ORC may also modify the rate of inflation based
on the occupant size. The ORC receives this data from
the Occupant Classification Module (OCM). The ORC
will detect roll over, but not rear impacts.

²Turns on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
²Unlocks the doors automatically.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system could cause it to fail when
you need it. You could be injured if the airbag system is not there to
protect you. Do not modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub trim cover or the
upper passenger side of the instrument panel. Do not modify the front
bumper or vehicle body structure.
²Do not attempt to modify any part of your advanced airbag system. The
airbag may inflate accidentally or may not function properly if modifica-
tions are made. Take your vehicle to an authorized dealer for any advanced
airbag system service. If your seat including your trim cover and cushion
needs to be serviced in any way (including removal or loosening/
tightening of seat attachment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accessories may be used. If it is
necessary to modify an advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
²Do not place or hang any items such as add-on video players on the front
passenger seat back. The additional weight may cause the Occupant
Classification System to be unable to classify the front seat passenger
correctly. This could allow the passenger frontal airbag to inflate when it
is not desired.
²It is dangerous to try to repair any part of the airbag system yourself. Be
sure to tell anyone who works on your vehicle that it has an airbag system.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle's hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements Ð Trailer Lights & Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may includea4and7pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
