GENERAL INFORMATION 0A-3
PRECAUTIONS
PRECAUTION FOR VEHICLES EQUIPPED
WITH A SUPPLEMENTAL RESTRAINT (AIR
BAG) SYSTEM
WARNING:

The configuration of air bag system parts are as shown in
the figure. When it is necessary to service (remove, rein-
stall and inspect) these parts, be sure to follow proce-
dures described in Section 9J. Failure to follow proper
procedures could result in possible air bag deployment,
personal injury, damage to parts or air bag being unable
to deploy when necessary.

If the air bag system and another vehicle system both
need repair, Suzuki recommends that the air bag system
be repaired first, to help avoid unintended air bag deploy-
ment.

Do not modify the steering wheel, dashboard, or any other
air bag system component. Modifications can adversely
affect air bag system performance and lead to injury.

If the vehicle will be exposed to temperatures over 93C,
200F (for example, during a paint baking process), re-
move the air bag system components (air bag (inflator)
modules, sensing and diagnostic module) beforehand to
avoid component damage or unintended deployment.
DIAGNOSIS

When troubleshooting air bag system, be sure to follow
“DIAGNOSIS” in Section 9J. Bypassing these procedures
may result in extended diagnostic time, incorrect diagnosis,
and incorrect parts replacement.

Never use electrical test equipment other than that specified
in this manual.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

NOTE:

There are two kinds of colored wire used in this vehicle. One is
single-colored wire and the other is dual-colored (striped) wire.
The single-colored wire uses only one color symbol (i.e. “G”).
The dual-colored wire uses two color symbols (i.e. “G/Y”). The first
symbol represents the base color of the wire (“G” in the figure) and
the second symbol represents the color of the stripe (“Y” in the fig-
ure).

MAINTENANCE AND LUBRICATION 0B-21
[Parking brake]
Check that lever has proper travel.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
Steering

Check to ensure that steering wheel is free from in-
stability, or abnormally heavy feeling.

Check that the vehicle does not wander or pull to
one side.
Engine

Check that engine responds readily at all speeds.

Check that engine is free from abnormal noise and
abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting sys-
tem are free from abnormal noise and abnormal
vibration or any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter, tem-
perature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that air comes out from defroster
outlet when operating heater or air conditioning.
Set fan switch lever to “HI” position and mode lever to
defroster position for this check. WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.
