WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

17) Put on a pair of shop gloves to protect your hands from possible
irritation and heat when handling the deployed air bag (inflator)
module.
NOTE:
As a precaution, gloves and safety glasses are recom-
mended to prevent any possible irritation of the skin or
eyes.
18) Disconnect the deployment harness from the air bag (inflator)
module as soon after deployment as possible. This will prevent
damage to the deployment harness due to possible contact
with the hot air bag (inflator) module canister. The deployment
harness are designed to be reused. They should, however, be
inspected for damage after each deployment and replaced if
necessary.
19) Dispose of the deployed air bag (inflator) module through nor-
mal refuse channels after it has cooled for at least 30 minutes
and tightly seal the air bag (inflator) module in a strong vinyl
bag. (Refer to ªDeployed Air Bag (Inflator) Modules Disposalº
in detail.)
20) Wash your hands with mild soap and water afterward.
NOTE:
The remaining steps are to be followed in the unlikely event
that the air bag (inflator) module did not deploy after following
these procedures.
21) Ensure that the deployment harness has been disconnected
from the power source and that its two banana plugs have been
shorted together by fully seating one banana plug into the oth-
er.
22) Disconnect the deployment harness from the air bag (inflator)
module.

with Steps 23) through 26). If the the seat belt pretensioner did
activate, proceed with Steps 19) through 22).
19) Put on a pair of shop gloves to protect your hands from possible
irritation and heat when handling the activated seat belt preten-
sioner.
NOTE:
As a precaution, gloves and safety glasses are recom-
mended to prevent any possible irritation of the skin or
eyes.
20) Disconnect the deployment harness from the seat belt preten-
sioner as soon after activation as possible. This will prevent
damage to the deployment harness due to possible contact
with the hot seat belt pretensioner canister. The deployment
harness are designed to be reused. They should, however, be
inspected for damage after each activation and replaced if nec-
essary.
21) Dispose of the activated seat belt pretensioner through normal
refuse channels after it has cooled for at least 30 minutes and
tightly seal the seat belt pretensioner in a strong vinyl bag. (Re-
fer to ªActivated Seat Belt Pretensioners Disposalº in detail.)
22) Wash your hands with mild soap and water afterward.

24) Temporarily store the seat belt pretensioner. At that time, be
sure NOT to face its exhaust hole provided side down. It must
face up. Refer to ªService Precautionsº in this section for de-
tails.
25) Contact your local distributor for further assistance.
DEPLOYED AIR BAG (INFLATOR)
MODULES DISPOSAL
WARNING:
Failure to follow proper air bag (inflator) module disposal
procedures can result in air bag deployment which may
cause personal injury. Undeployed air bag (inflator) module
must not be disposed of through normal refuse channels.
The undeployed air bag (inflator) module contains sub-
stances that can cause severe illness or personal injury if
the sealed container is damaged during disposal.
Deployed air bag (inflator) modules (driver/passenger) can be dis-
posed of through normal refuse channels just like any other parts.
For their disposal, however, following points should be noted.

The air bag (inflator) module immediately after deployment is very
hot. Wait for 30 minutes to cool it off before handling it.

Never apply water, oil, etc. to deployed air bag (inflator) module
to cool it off and be careful so that water, oil etc. does not get on
the deployed air bag (inflator) module.

After the air bag (inflator) module has been deployed, the surface
of the air bag may contain a powdery residue. This powder con-
sists primarily of cornstarch (used to lubricate the bag as it in-
flates) and byproducts of the chemical reaction. As with many ser-
vice procedures, you should wear gloves and safety glasses.

When disposing of the deployed air bag (inflator) module, be sure
to seal it in a vinyl bag.

When air bag (inflator) module(s) have been deployed inside the
vehicle which is going to be scrapped, leave them as installed to
the vehicle.

Be sure to wash your hands with mild soap and water after han-
dling it.
