2008 BUICK LACROSSE Owner's Manual

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 3-33.
