Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any
other loose or damaged safety belt system parts.
If you see anything that might keep a safety belt
system from doing its job, have it repaired. See
Care of Safety Belts on page 5-92for more information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers, and
have them repaired or replaced. The airbag system
does not need regular maintenance.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the side
impact airbag covering (if equipped) on the ceiling
near the side windows, the airbag may not work
properly. You may have to replace the airbag
module in the steering wheel, both the airbag
module and the instrument panel for the right front
passenger’s airbag, or side impact airbag module
and ceiling covering for roof-mounted side impact
airbags (if equipped.) Do not open or break the
airbag coverings.

switch cannot be turned to LOCK unless the shift lever
is in PARK (P).

ignition switch could cause damage or break the
key. Use the correct key and turn the key only
with your hand. Make sure the key is all the way in.

you turn the key hard. If none of this works,
then your vehicle needs service.

ON to operate your electrical accessories and to display
some instrument panel cluster warning and indicator
lights. The transmission is also unlocked in this position
on automatic transmission vehicles.START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch will return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the
radio or items plugged into the accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and the key
is in the ignition.

Your radio, wipers and power windows will work when
the ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features will continue to
work for up to 20 minutes or until a door is opened.
