Replacing Restraint System Parts
After a Crash
{WARNING:
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 the vehicle has been in a crash, do you need newsafety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.But the safety belt assemblies that were used during anycrash may have been stressed or damaged. See yourdealer/retailer to have the safety belt assembliesinspected or replaced.
If the vehicle has the LATCH system and it was beingused during a crash, you may need new LATCH systemparts.
New parts and repairs may be necessary even if thesafety belt or LATCH system (if equipped), wasnot being used at the time of the crash.
If an airbag inflates, you will need to replace airbagsystem parts. See the part on the airbag system earlierin this section.
Have the safety belt pretensioners checked if thevehicle has been in a crash, if the airbag readiness lightstays on after the vehicle is started, or while you aredriving. SeeAirbag Readiness Light on page 4-50.

The system checkincludes the airbag sensor, the pretensioners, the airbagmodules, the wiring and the crash sensing anddiagnostic module. For more information on the airbagsystem, seeAirbag System on page 2-58.
The airbag readiness lightflashes for a few secondswhen the engine isstarted. If the light doesnot come on then, have itfixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbagDriver Information Center (DIC) message can also comeon. SeeDIC Warnings and Messages on page 4-67for more information.

If the word ON or the on symbol is lit on the passengerairbag status indicator, it means that the right frontpassenger frontal airbag and seat-mounted side impactairbag are enabled (may inflate).
If the word OFF or the off symbol is lit on the passengerairbag status indicator, it means that the passengersensing system has turned off the right front passengerfrontal and seat-mounted side impact airbag.
If, after several seconds, both status indicator lightsremain on, or if there are no lights at all, there may be aproblem with the lights or the passenger sensingsystem. See your dealer/retailer for service.
