10-4 RESTRAINT SYSTEM
ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
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 or latch plate.
Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)
When installing a seat belt anchor bolt, it should be tightened by hand at first to prevent cross-threading and
then to specified torque.
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.
For Seat Belt with Pretensioner
Refer to “SERVICE AND DIAGNOSIS” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
DISABLING AIR BAG SYSTEM
Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
ENABLING AIR BAG SYSTEM
Refer to “ENABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
HANDLING AND STORAGE
Refer to “HANDLING AND STORAGE” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
DISPOSAL
Refer to “DISPOSAL” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Section 10B. 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 rea-
son, SUZUKI will supply only the spare buckle and ELR (or webbing) in a set part.
WARNING:
When performing service on or around air bag system components or air bag system wiring, disable
the air bag system. Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under
“ON-VEHICLE SERVICE” in Section 10B.
Failure to follow procedures could result in possible air bag activation, personal injury or unneeded
air bag system repairs.
10-6 RESTRAINT SYSTEM
REMOVAL
1) Disconnect negative battery cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under
“ON-VEHICLE SERVICE” in Section 10B.
3) Remove center pillar lower trim.
4) Disconnect Yellow connector for seat belt pretensioner.
a) Release locking of lock lever.
b) After unlocked, disconnect to connector.
5) Remove front seat belts from the vehicle.
INSPECTION
Seat belts and attaching parts can affect the vital components
and systems of a vehicle.
Therefore, they should be inspected carefully and replaced with
genuine parts only.
Seat belt
Its webbing or strap should be free from damage.
Retractor assembly
It should lock webbing when pulled quickly.
The front seat belt retractor assembly (1) should pass the
above inspection and should lock webbing even when tilted
(approx. 15°) toward the fore and aft or right and left direc-
tions.
Check retractor assembly (1) with seat belt pretensioner
appearance visually for following symptoms and if any one of
them is applicable, replace it with a new one as an assem-
bly.
Pretensioner has activated.
There is a crack in seat belt pretensioner (retractor assem-
bly).
Wire harness or connector (2) is damaged.
Seat belt pretensioner (retractor assembly) is damaged or a
strong impact (e.g., dropping) was applied to it.
Anchor bolt
Anchor bolts should be torqued to specification.
Belt latch
It should be secure when latched. WARNING:
Never measure resistance of pretensioner or disassem-
ble it. Otherwise, personal injury may result.
CAUTION:
If seat belt pretensioner (retractor assembly) was
dropped from a height of 30 cm (1 ft) or more, it should
be replaced.
RESTRAINT SYSTEM 10-7
INSTALLATION
Install in reverse order of removal, noting the following.
Seat belt anchor bolts should have an unified fine thread (7/
16-20 UNF). Under no circumstances should any different
sized or metric screw threads be used.
Connect Yellow connector (1) for seat belt pretensioner
securely and fit seat belt pretensioner connector onto body.
a) Connect connector
b) Lock connector with lock lever
Enable air bag system. Refer to “ENABLING AIR BAG SYS-
TEM” under “SERVICE PRECAUTIONS” in Section 10B.

Service on or around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in this section before performing service on or around the air bag system compo-
nents or wiring. Failure to follow WARNINGS could result in unintended activation of the system or
could render 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
temporarily 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 system repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. 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
conditions are not followed, parts or system damage could result.

CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

NOSTIC SYSTEM CHECK”.
HANDLING AND STORAGE
SDM
Never attempt disassembly of SDM.
When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
If SDM has been dropped, replace it with a new one.
If installation part of SDM was damaged, repair that part
completely before reinstallation.
All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
WARNING:
Never power up air bag system when SDM is not rigidly
attached to the vehicle. Otherwise, personal injury may
result.
CAUTION:
After detecting one time of such collision as to meet
deployment conditions, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.
AIR BAG SYSTEM 10B-57
INSPECTION
Check SDM (3) and SDM plate (5) for dents, cracks or defor-
mation.
Check SDM connector (2) for damage, cracks or lock mech-
anism.
Check SDM terminal for bent, corrosion or rust.
If any faulty condition is found in above checks, replace.
INSTALLATION
For installation, reverse removal procedure, nothing following
points.
Ensure that arrow (4) on the SDM (3) is pointing toward the
front of the vehicle.
Tighten SDM bolts to specified torque.
Tightening torque
SDM mounting bolt (a) : 6 N·m (0.6 kg-m, 4.5 lb-ft)
Connect SDM connector (2) to SDM (3) securely.
Enable air bag system. Refer to “ENABLING AIR BAG SYS-
TEM”. CAUTION:
Do not connect a tester whatever type it may be.
Never repair or disassemble SDM (3).
If SDM has been dropped, or if there are cracks, dents
or other defects in the case or plate, replace it with a
new one.
