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.

SIDE AIRBAG SENSOR
Removal and Installation Procedure
CAUTION : The sensing and diagnostic mod-
ule(SDM) can maintain sufficient voltage to
deploy the airbags and pretensioners for 1minute
after the ignition is OFF and the fuse has been re-
moved. If the airbags and pretensioners are not
disconnected, do not begin service until one
minute has passed after disconnecting power to
SDM. If the airbags are disconnected, service can
be executed immediately without waiting for
one–minute time period to expire. Failure to tem-
porarily disable the SIR during service can result
in unexpected deployment, personal injury and
unnecessary SIR repairs.

bag or a pretensioner in the vehicle, observe the
following precaution :
S Before deploying the airbags, remove all loose ob-
jects from the airbag’s expansion area.
S Deploy the airbags with the vehicle doors closed
and the side windows open.
S Deploy the airbags only in an evacuated area. Ser-
vice personnel who must be present during the de-
ployment should be at least 10 meters(33 feet) in
front of the vehicle.
S Do not connect the voltage source until after having
completed all other preparations for the deployment
of airbags.
S Allow a deployed airbag module or pretensioner
cool for 30 minutes before handling.
S Wear gloves and eye protection during the disposal
procedure.
S If the deployment fails, disconnect the voltage
source and wait 5 minutes before approaching the
vehicle.

DEPLOYED AIRBAG MODULE
DISPOSAL PROCEDURE
CAUTION : After deployment, a powdery residue
may be on the surface of the airbag. The powder
primarily consists of cornstarch(used to lubri-
cate the bag as it inflates) and by–products of the
chemical reaction. The sodium hydroxide then
quickly reacts with atmospheric moisture and is
converted to sodium carbonate and sodium bi-
carbonate(also known as baking soda). There-
fore, it is unlikely that sodium hydroxide will be
presents after deployment.
CAUTION : Be sure to wear gloves and eye
protection during the disposal procedure.
CAUTION : After deployment, the metal surfaces
of the airbag module will be hot. In order to avoid
the risk of an injury or a fire do not place the
deployed airbag module near any flammable ob-
jects, and allow the airbag module to cool 30 min-
utes before handling.
Deploy an airbag or pretensioner before disposing of
it.
This includes those in a whole vehicle being
scrapped. If the vehicle is still within the warranty peri-
od contact the Daewoo regional service manager for
approval or special instructions before deploying an
airbag module or a pretensioner. Deployed airbag
module or pretensioner should be disposed of in the
same manner as other scrap parts, with the addition
of the following steps :
1. Place the deployed airbag or pretensioner in a
sturdy plastic bag.
2. Seal the plastic bag securely.
3. Wash your hands and rinse them with water after
handling a deployed airbag.
