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).

CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
WARNING:
If replacing seat belt is necessary, replace buckle and ELR (or webbing) together as a set. This is for
the reason of ensuring locking of tongue plate with buckle. If these parts are replaced individually, such
a locking condition may become unreliable. For this reason, SUZUKI will supply only the spare buckle
and ELR (or webbing) in a set part.
Before servicing or replacing seat belts, refer to following precautionary items.

Seat belts should be normal relative to strap retractor and buckle portions.

Keep sharp edges and damaging objects away from belts. Avoid bending or damaging any portion of belt buckle,
latch plate and ELR.

Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)

When installing a seat belt anchor bolt, start bolt by hand to prevent cross-threading.

Use only the correct seat belt anchor bolts and screws and tighten to the correct torque value.

Do not attempt any repairs on retractor mechanisms or retractor covers. Replace defective assemblies with new
replacement parts.

Keep belts dry and clean at all times.

If there exist any parts in question, replace such parts.

Replace belts whose webbing is cut or otherwise damaged.

Do not put anything into trim panel opening which seat belt webbing passes through.

SECTION 10B
AIR BAG SYSTEM
WARNING:

Service on or around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in this section before performing service on or around the air bag system components or
wiring. Failure to follow WARNINGS could result in unintended activation of the system or could ren-
der the system inoperative. Either of these two conditions may result in severe injury.

The procedures in this section must be followed in the order listed to disable the air bag system tem-
porarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures could
result in possible activation of the air bag system, personal injury or otherwise unneeded air bag sys-
tem repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above condi-
tions are not followed, parts or system damage could result.
