GENERAL DESCRIPTION
AND SYSTEM OPERATION
DRIVER SEAT BELT WARNING
The driver’s safety belt incorporates a safety belt reminder
light in the instrument cluster to remind the driver if the
safety belt is not fastened when the the ignition is turned
ON.
THREE–POINT ELR FRONT SEAT
BELT WITH PRETENSIONER
The three–point emergency locking retractor (ELR) front
seat belt pretensioner is always unlocked, allowing the
passenger freedom of movement, except in emergencies
such as rapid deceleration, rapid acceleration, or hard cor-
nering maneuvers.
The front seat belt pretensioner contains an ignitor charge
and a gas generator to inflate the pretensioner. The pre-
tensioner also includes wiring and a connector. The con-
nector of the pretensioner contains a shorting bar which
short–circuits the pretensioner high circuit to the preten-
sioner low circuit when the connector is disconnected. The
shorting bar prevents current from traveling through the
pretensioner during servicing. The shorting bar disen-
gaged when the connecotr is connected.
The pretensioner is an electronically controlled pyrotech-
nical reactor which reduce seat belt slack when it is actived
with air bags.
The front seat belt pretensioner must be replaced after an
accident that cause its activation.
THREE–POINT CLR (ELR) REAR
OUTBOARD SEAT BELT
The rear outboard seating positions use the three–point
child locking retractor (CLR) or emergency locking retrac-
tor (ELR) seat belts. The three–point CLR (ELR) seat beltis always unlocked, allowing the passenger freedom of
movement, except in emergencies such as rapid decel-
eration, rapid acceleration, or hard cornering maneuvers.
