How The Airbag System Works
²
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may

Also, the fuel system will shut off immediately upon
airbag deployment (gasoline models only). The ignition
switch will need to be cycled (i.e. turn the ignition key
from the ON position to the LOCK position) after ap-
proximately 5 seconds in order to restart the vehicle.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 right side of the instrument panel. Do not modify
the front bumper, vehicle body structure, or add aftermar-
ket side steps or running boards.
²Do not attempt to modify any part of your advanced airbag
system. The airbag may inflate accidentally or may not
function properly if modifications 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, 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 disabilities, con-
tact your authorized dealer.

Engine Timing Belt Ð 2.4L Engine
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Ignition Wiring System Ð 2.4L Engine
Replace the ignition cables at the intervals described in
the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on ªMaintenance Schedule A.º If,
however, you drive the vehicle frequently under dusty or
severe conditions, the filter element should be inspected
periodically and replaced if necessary at the intervals
shown on ªMaintenance Schedule B.º
WARNING!
The air cleaner can provide protection in the case of
engine backfire. Do not remove the air cleaner
unless it is necessary for repair or maintenance.
Make sure that no one is near the engine compart-
ment before starting the vehicle with the air cleaner
removed. Failure to do so can result in serious
personal injury.
