SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B – 95
DAEWOO V–121 BL4
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.
1. Disconnect the negative battery cable.
2. Remove the trim from B pillar.
3. Remove the side airbag sensor mounting bolts.
4. Remove the side airbag sensor.
5. Installation should follow the removal procedure in
the reverse order.
Tightening torque of the side airbag sensor mounting
bolts is 8 NSm (71 lb–in).
FRONT SEAT BELT PRETENSIONER
For removal and installation, refer to Section 8A, Seat
Belts.
AIRBAG MODULE DEPLOYMENT
(INSIDE OF VEHICLE)
Deploy the airbags before disposing them. If a vehicle
to be scrapped, the airbag may be deployed inside the
vehicle.
CAUTION : To avoid injury while deploying an air-
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.

9E – 30IINSTRUMENTATION/DRIVER INFORMATION
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
CIGAR LIGHTER
The cigar lighter is located in the front portion of the floor
console. To use the lighter, push it in completely. When the
lighter is hot, it will release itself from contact with the heat-
ing element. The lighter and the heating element can be
damaged if the lighter is not allowed to release itself fully
from the heating element.
ASHTRAY
The ashtray is located below the audio system. To access
the ashtray, pull it out from the center console. The ashtray
lamp will go on when the parking lamps or the headlamps
are turned on.
INSTRUMENT PANEL VENTS
The center and the side vents in the instrument panel can
be adjusted up and down and from side to side. The side
vents can also be aimed toward the side windows in order
to defog them.
GLOVE BOX
The glove box can be opened by pulling up on the latch
handle. The glove box must be removed in order to gain
access to the passenger’s side airbag module.
DIGTAL CLOCK
The digital clock is located in the instrument panel, above
the audio system. The clock is capable of a 12–hour or a
24–hour display.
INSTRUMENT CLUSTER
The instrument cluster is located above the steering col-
umn and in the instrument cluster trim panel. The instru-
ment cluster contains the instruments that provide the
driver with vehicle performance information. The instru-
ment cluster contains a speedometer, an odometer, a trip
odometer, a temperature gauge, a fuel gauge, and several
indicator lamps. For replacement of the indicator lamp
bulbs contained in the instrument cluster, refer to ”Instru-
ment Cluster Indicator Lamps Specifications” and”Instru-
ment Cluster Indicator Lamps” in this section.
SPEEDOMETER/ODOMETER/TRIP
ODOMETER
The speedometer measures the speed of the vehicle in
km/h (mph in some countries). It consists of an instrument
cluster gauge connected to the vehicle speed sensor
(VSS) on the transaxle output shaft.The odometer measures in kilometers (miles in some
countries) the total distance the vehicle has traveled since
it was manufactured. It consists of an instrument cluster
gauge connected to the VSS on the transaxle output shaft.
The trip odometer measures the distance the vehicle has
traveled since the odometer was last reset. It consists of
an instrument cluster gauge connected to the VSS on the
transaxle output shaft. The trip odometer can be reset to
zero at any time so that the driver can record the distance
traveled from any starting point.
FUEL GAUGE
The fuel gauge consists of an instrument cluster gauge
connected to a sending unit in the fuel tank.
The fuel gauge indicates the quantity of fuel in the tank
only when the ignition switch is turned to ON or ACC.
When the ignition is turned to LOCK or START, the pointer
may come to rest at any position.
TEMPERATURE GAUGE
The temperature gauge consists of an instrument cluster
gauge connected to a temperature sensor that is in con-
tact with the circulating engine coolant.
The temperature gauge indicates the temperature of the
coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the
gauge. The engine is overheating if the pointer moves into
the red zone at the upper limit of the gauge.
INSTRUMENT CLUSTER INDICATOR
LAMPS
The instrument cluster contains indicator lamps that indi-
cate the functioning of certain systems or the existence of
potential problems with the operation of the vehicle. The
indicator lamps are replaceable. For replacement of the in-
dicator lamps contained in the instrument cluster, refer to
”Instrument Cluster Indicator Lamps Specifications”
and”Instrument Cluster Indicator Lamps” in this section.
CHIME MODULE
The chime module is located above the instrument panel
fuse block and will sound in order to bring attention to one
or more of the following conditions:
S The lamps are on, the door is ajar, and the ignition
switch is not in ACC, ON, or START.
S The seat belt is unbuckled when the ignition switch
is in ON or START.
S The door is open when the ignition switch is in ON
or START.
S The key is left in the ignition switch when the igni-
tion is in LOCK and the door is open.

9G – 16IINTERIOR TRIM
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
INTERIOR TRIM PANELS
The interior trim panels are molded plastic and fasten with
screws or plastic clips.
PRESSURE RELIEF VENT
When all the windows are closed and the ventilation sys-
tem is on, the addition of outside air to the interior of the
vehicle causes a positive pressure within the vehicle. To
relieve the pressure, air is released through a pressure re-
lief vent. The pressure relief vents are located at the rear
quarter of the vehicle, behind the bumper fascia.
FLOOR CONSOLE
The floor console fits over the tunnel in the floor of the ve-
hicle and extends from under the center of the instrument
panel to the rear seat area. The front portion of the consolecontains the cigar lighter and the transaxle shift lever. The
rear portion of the console contains the parking brake le-
ver, a cupholder, a storage compartment, and an ashtray
for the rear seat occupants.
The sensing and diagnostic module (SDM) for the airbag
system and the remote keyless entry module are located
under the console.
FLOOR CARPET
The one–piece floor carpet goes over both the front and
the rear floor pans.
REAR COMPARTMENT SECURITY
COVER (HATCHBACK)
A rear compartment security cover is provided on the
hatchback model. The security cover is attached to the
hatch and can be easily removed if more cargo space is
needed.

SECTION : 9P
DOORS
CAUTION : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool
or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help
prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.
