8A – 2  SEAT BELTS

DESCRIPTION AND OPERATION

DRIVER SEAT BELT WARNING

The driver’s safety belt incorporates a safety belt re-
minder light in the instrument cluster to remind the driver
if the safety belt is not fastened when the ignition is
turned ON.

THREE-POINT PRETENSIONER
FRONT SEAT BELT (W/EUROPE
ONLY)

The pretensioner front seat belt is optional. It contains a
electrically-controlled pyrotechnical retractor, which re-
duces seat belt slack when it is activated in a head-on or
angled front collision. The pretensioner front seat belt
must be replaced after an accident that causes its ac-
tivation.

THREE-POINT WLR FRONT SEAT
BELT

The three-point web locking retractor (WLR) seat belt
will limit the movement of the driver and offer better
protection in an accident.

THREE-POINT ELR FRONT SEAT
BELT

The three-point emergency locking retractor (ELR) front
seat belt is always unlocked, allowing the passenger
freedom of movement, except in emergencies (rapid de-
celeration, rapid acceleration, or hard cornering maneu-
vers).

THREE-POINT ELR REAR
OUTBOARD SEAT BELT

The rear outboard seating positions use the three-point
emergency locking retractor (ELR) seat belts. The
three-point emergency locking retractor (ELR) seat belt

is always unlocked, allowing the passenger freedom of
movement, except in emergencies (rapid deceleration,
rapid acceleration, or hard cornering maneuvers).

TWO-POINT LAP REAR CENTER
SEAT BELT

The two-point lap rear center seat belt is a single contin-
uous length of webbing. The webbing is routed from the
anchor through a latch plate and into a single retractor.

OPERATIONAL AND FUNCTIONAL
CHECKS

Caution:

D

Keep sharp objects and potentially damaging ob-
jects away from the seat belts.

D

Avoid bending or damaging any portion of the
buckle or the latch plate.

D

Do not bleach or dye the belt webbing. Use only
mild soap and water in order to clean the belts.

D

When installing the seat belt anchor bolts and
the screws, start the bolts and the screws by
hand in order to prevent crossthreading.

D

Do not attempt any repairs on the retractor mech-
anisms or the covers. Replace any defective as-
semblies with new assemblies.

D

Replace any belts that are cut or damaged in any
way.

1. Inspect all seat belt anchor bolts and the screws in or-

der to verify that they are secure.

2. Inspect the seat belt buckle. The buckle must lock

and unlock easily.

3. After inserting the latch into the buckle, tug sharply on

the belt. The buckle must remain locked.

4. Fully extend the shoulder belt portion to make sure

that there is no twisting or tears in the belt.

5. Let the shoulder belt retract fully. The belt should re-

tract easily.
