• Never attempt disassembly of the air bag (inflator) modules.
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live (undeployed) air bag (inflator) module, be sure to
deploy it before discarding it.
• When grease, cleaning agent, oil, water, etc., got on the air bag (inflator) modules (driver, passenger, side
of both sides and curtain of both sides), wipe it off
immediately with a dry cloth.
• If air bag (inflator) module was dropped from a height of 90 cm (3 ft) or more, it should be replaced with a
new one as an assembly.
WARNING!
• For handling and storage of a live air bag (inflator) module, select a place where the
ambient temperature below 65 °C (150 ° F),
without high humidity and away from
electric noise.
• When carrying a live air bag (inflator) module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module.
Otherwise, personal injury may result.

WARNING!
When placing a live air bag (inflator) module
on bench or other surface, always face the
bag up, away from the surface. As the live
passenger air bag (inflator) module must be
placed with its bag (trim cover) facing up,
place it on the workbench with a slit (1) or
use the workbench vise (2) to hold it securely
at its lower mounting bracket (3).
It is also prohibited to place anything on top
of the trim cover and stack air bag (inflator)
modules.
This is necessary so that a free space is
provided to allow the air bag to expand in the
unlikely event of accidental deployment.
Otherwise, personal injury may result.

Live (Inactivated) Seat Belt Pretensioner
Special care is necessary when handling and storing a
live (inactivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is
generated and the seat belt (1) is retracted into the
retractor assembly (2) quickly.
Note, therefore, that if they activate accidentally, the seat
belt pretensioners and other object(s) around them may
be thrown through the air.

• When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• When installing it, be careful so that the air bag wire harness is not caught or does not interfere with other
parts.
• Make sure air bag system grounding point (2) is clean and ground is securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.Precautions on Disposal of Air Bag and Seat
Belt Pretensioner
S7RS0B8200003
Do not dispose of the live (undeployed) air bag (inflator)
modules and the live (inactivated) seat belt
pretensioners.
When disposal is necessary, be sure to deploy / activate
the air bag and seat belt pretensioner according to
deployment / activation procedure described in “Air Bag
(Inflator) Module and Seat Belt Pretensioner Disposal”.
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which could
cause personal injury. Undeployed air bag
(inflator) module and inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
inactivated seat belt pretensioner contain
substances that can cause severe illness or
personal injury if the sealed container is
damaged during disposal.

General Description
Air Bag System ConstructionS7RS0B8201001
With the air bag system which includes front air bags,
side curtain-air bag and side-air bags for both the
driver’s and passenger’s sides as well as the seat belt
pretensioners, the sag of the s eat belt is taken up (for
seat belt with pretensioner), the driver air bag (inflator)
module is deployed from th e center of the steering
column and the passenger air bag (inflator) module from
the top of the instrument panel in front of the front
passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement
protection offered by the driver and front passenger seat
belts.
Side-air bag (inflator) module is deployed from the side
of the seat back in occurrence of a sideward collision
with an impact larger than a certain set value.
Side curtain-air bag (inflator) module is deployed from
the roof side in occurrence of a sideward collision with
an impact larger than a certain set value.

The air bag system is designed to activate only in severe
frontal and sideward collisions. It is not designed to
activate in rear impacts, rollovers, or minor frontal and
sideward collisions, since it would offer no protection in
those types of accidents.

DTC CheckS7RS0B8204004
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (DLC) located on underside of instrument panel at
driver’s seat side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
If communication between scan tool and SDM is not
possible, check if scan tool is communicable by
connecting it to SDM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible. 5) After completing the check,
turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).
