Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system
may not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the belt assemblies that were used during any crash
may have been stressed or damaged. See your
dealer/retailer to have your safety belt assemblies
inspected or replaced.If your vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH
system parts.
New parts and repairs may be necessary even if the
belt or LATCH system (if equipped), was not being used
at the time of the crash.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have your safety belt pretensioners checked if your
vehicle has been in a crash, if your airbag readiness
light stays on after you start your vehicle, or while you
are driving. SeeAirbag Readiness Light on page 3-34.

about ve seconds after the key is turned to ON/RUN.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release the
key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock system is not
working properly and must be serviced by your
dealer/retailer. Your vehicle is not protected by Passlock
at this time. You may also want to check the fuse.
