SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B–3
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
(Left–Hand Drive Shown, Right–Hand Drive Similar)
AIRBAG MODULE
Driver Airbag Module
Caution: Tampering with the driver side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the driver side air-
bag module should never be disassembled.
The driver airbag module is under the center pad on the
steering wheel.
The driver airbag module contains an ignitor charge and
a gas generator to inflate the folded airbag.
D110B006
Passenger Airbag Module
Caution: Tampering with the passenger side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the passenger side
airbag module should never be disassembled.
The passenger airbag module is on the passenger side
of the instrument panel.
The passenger airbag module contains an ignitor charge
and a gas generator to inflate the folded airbag.
SENSING AND DIAGNOSTIC
MODULE (SDM)
The SDM

Has no user-serviceable parts.

Is under the front console assembly.

Continuously monitors the system components.

Records any faults which are discovered.
Illuminates a warning lamp that alerts the driver to
any faults.

Allows the fault codes to be retrieved with a scan tool.
The SDM controls the deployment of the airbag system
through the use of the

Arming sensor.

Capacitor.

Crash sensor, or accelerometer.
D110B007
Arming Sensor
The arming sensor is safety device made up of a dual-
contact, electro-mechanical switch that:

Acts independently of the electronic components.

Keeps the firing circuits for the airbags unarmed un-
der normal driving conditions.

Allows the airbags to deploy under the required
conditions.
Capacitor
The capacitor provides reserve power.
Crash Sensor
The crash sensor, or accelerometer, electronically rep-
resents the acceleration or deceleration of the vehicle
during a frontal impact. In this electronic representation,
the electrical signal is proportional to the acceleration or
deceleration of the vehicle.
SIR WARNING LAMP
The supplemental inflatable restraints (SIR) system in-
cludes a self-diagnostic function.

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.
