SAFETY 241
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the exhaust
system each time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision if
they have been damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt or retractor
condition, replace the seat belt.Air Bag Warning Light
The Air Bag warning light will turn on for four to eight
seconds as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on during
starting, stays on, or turns on while driving, have the system
inspected at an authorized dealer as soon as possible. After
the bulb check, this light will illuminate with a single chime
when a fault with the Air Bag System has been detected. It
will stay on until the fault is removed. If the light comes on
intermittently or remains on while driving, have an autho
-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and place the
blower control on high speed. You should be able to feel the
air directed against the windshield. See an authorized dealer
for service if your defroster is inoperable.
