when the ignition is first switched to the ON position.
Correct Functioning
The system is working properly if:

The SIR warning lamp turns OFF after approximately
four seconds.
Faulty Functioning
The system is not working properly, meaning one of the
SIR components or the wiring connector is faulty, if:

The SIR warning lamp fails to turn ON when the
ignition is first switched ON.

The SIR warning lamp remains ON.

CLOCK SPRING
The clock spring:

Is on the steering column.

Contains a coil that is the electrical contact between
the steering column wiring harness and the driver
side airbag module.

Is part of the circuit for the horn.
Notice: Turning the steering wheel more than three and
one-quarter turns may damage the clock spring.
Turning the steering wheel:

In one direction tightens the coil.

In the opposite direction loosens the coil.

More than three and one-quarter turns may damage
the clock spring.
Caution: Disassembling the clock spring can cause
injury and vehicle damage.The clock spring should never be disassembled.
The clock spring must be replaced if the airbags have
been deployed.
D110B008A
WIRING HARNESS/CONNECTORS
The connector for the sensing and diagnostic module
(SDM) has a built-in shorting bar that will turn ON the
warning lamp if there is a poor connection at the SDM.
As an anti-deployment mechanism, additional shorting
bars are in the

Connector for the clock spring at the lower steering
column.

Passenger airbag module connector.

SDM connector.
When these connectors are separated, the shorting
bars will short circuit any current which is applied, pre-
venting the current from reaching the airbag modules.
SIR SYSTEM
The supplemental inflatable restraints (SIR) system is a
safety device used in conjunction with the seat belts.
The airbag does not replace the function of the seat belt.
The driver and the passengers must always fasten their
seat belts and adjust them for a proper fit.
The SIR is designed to protect the driver and the front
seat passenger in the event of a significant frontal im-
pact to the vehicle. The airbags deploy if the force is ap-
plied from a direction within 30 degrees of the vehicle’s
centerline and above 25 km/h (15 mph) speed.
The SIR consists of a

Driver airbag module.

9B – 2 LIGHTING SYSTEMS
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
HEADLAMPS AND PARKING LAMPS
The headlamps are controlled by the multifunction lever
located on the left side of the steering column. They will
come on with the ignition switch in any position. Turning
the headlamp switch to the first position turns on the
parking lamps, the license plate lamps and the instru-
ment panel illumination. Turning the switch to the sec-
ond position turns on all of the previous lamps and the
headlamps. Turning the switch to the off position turns
off all the lamps.
The parking lamps can be turned on by turning the light-
ing switch to the first position. The parking lamps can be
turned off by turning the switch to the OFF position.
Headlamp high beam and low beam are also controlled
by this lever. When the headlamps are on, pushing the
lever away from the driver until the switch clicks
changes the lamp from low beam to high beam. An indi-
cator lamp on the instrument cluster assembly will come
on when the high beam headlamps are on. To return the
headlamps to low beam, pull the lever toward the driver.
The headlamps must be aimed for proper illumination of
the road. Headlamp aim should be checked whenever a
new headlamp assembly is installed or service repairs to
the front end area may have disturbed the headlamp as-
sembly or its mountings.
FRONT TURN SIGNAL LAMPS
When the turn signals are activated, the side turn signal
lamps flash to signal a turn. The turn signal works only
when the ignition switch is on.
The turn signals are controlled by the light switch on the
left side of the steering column. Moving the lever all the
way up or down (past the detent) will turn on the turn sig-
nals. When the turn is completed, the lever will return to
horizontal and the turn signals will stop flashing.
For changing lanes or shallow turns where the steering
wheel does not turn far enough to cancel the signal,
move the signal only to the first detent and hold it there.
When the lever is released, it will return to horizontal and
the turn signal will cancel.
REAR FOG LAMP
The rear fog lamp is incorporated in the drive side tail-
lamp assembly and are controlled by the rear fog lamp
switch on the instrument panel. The rear fog lamp can
be turned on only when headlamps are on.
TAILLAMPS
The taillamps, stoplamps, backup lamp(s), rear fog lamp
(if equipped with) and turn signal lamps are one assem-
bly.
Turning on either the headlamps or the parking lamps
will also turn on the taillamps. When the brake pedal is
pushed, the taillamps will glow brighter to serve as sto-
plamps.
The center high-mounted stoplamp is located in the rear
window and will come on when the brake pedal is
pressed.
LICENSE PLATE LAMPS
The license plate lamps will come on when the head-
lamps or the parking lamps are on. The license plate
lamps are mounted on the rear bumper, above the li-
cense plate.
INTERIOR COURTESY LAMP
The courtesy lamp is located on the headliner just be-
fore the front seats. The lamp switch has three posi-
tions. If the switch is in the center position, the lamp will
go on whenever a door is opened and go off when it is
closed. In the ON position, the lamp will stay on until it is
turned off. In the OFF position, the lamp will not come
on, even when a door is opened.
BACKUP LAMP(S)
The backup lamps are located in the rear combination
lamps. They will come on when the transaxle is shifted
into REVERSE. On a vehicle with a manual transaxle,
they are activated by a reverse switch which is part of
the transaxle.
DAYTIME RUNNING LAMPS (DRL)
(W/Europe Only)
The daytime running lamps (DRL) work in conjunction
with the exterior lamps system. When the ignition switch
is turned to the ”II” position with the light switch off, park-
ing, tail, license plate and instrument panel lights illumi-
nate. And, when the engine is started, the headlamps
(low beam) also come on.
They remain on until the ignition switch is turned off or
the light switch is turned on. They revert to normal op-
eration when the light switch is on.
The daytime running lamps (DRL) is optional.

9C – 2 HORN
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
HORN
The horn is located under the hood. It is attached near
the radiator at the front of the vehicle. The horn is actu-ated by pressing the steering wheel pad, which grounds
the horn’s electrical circuit.

9D – 2 WIPERS/WASHER SYSTEMS
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
WINDSHIELD WIPER SYSTEM
The windshield wiper system consists of a wiper motor,
a linkage, a wiper arm and a blade, and a wiper/washer
switch. The windshield wiper circuit incorporates a self-
parking device which consists of a worm gear and a cam
plate in order to keep the circuit engage temporarily
when the switch is turned off. The wiper system is driven
by a permanent magnet-type motor. The windshield wip-
er motor is mounted on the dash panel and is directly
connected to the windshield wiper linkage.
The windshield wiper motor has two speeds, LOW and
HIGH, and also has intermittent wiper capability. The
wiper switch is an integral part of the wiper/washer
switch. Windshield wiper operation is actuated through
the lever on the right side of the steering column.
WINDSHIELD WASHER SYSTEM
The windshield washer system is equipped with a wash-
er fluid reservoir, a washer fluid pump, hoses, nozzles,and a wiper/washer switch. The windshield washer res-
ervoir is mounted inner the front right wheel well splash
shield. Attached to the reservoir is a washer pump,
which pumps fluid through the hoses to the two nozzles
mounted on the cowl panel. The washer switch is an in-
tegral part of the wiper/washer switch. Windshield wash-
er operation is actuated through the lever on the right
side of the steering column.
REAR WIPER/WASHER SYSTEM
The rear wiper/washer system is equipped with the high
grade vehicle. The rear wiper and the washer are one
assembly. The rear washer is installed to the rear wiper.
The rear wiper/washer switch is same with the wind-
shield wiper. Push the switch to one position forward
and the rear wiper operate slowly. And push more the
switch forward and the rear wiper/washer system oper-
ate.
