WARNING!
Be sure to read “Precautions on Service and
Diagnosis of Seat Belt” before starting to
work and observe every precaution during
work.

Removal1) Fold rear seats referring to “Folding Rear Seats” in Owners Manual.
2) Remove rear side sill scuff (1), quarter lower trim (2)
and quarter upper trim (3).
3) Remove rear seat belt referring to “Rear Seat Belt Components”. Installation
Reverse removal procedure for installation 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.Rear Seat Belt InspectionS7RS0B8106006
WARNING!
Be sure to read “Precautions on Service and
Diagnosis of Seat Belt” before starting to
work and observe every precaution during
work.

• Check the rear seat belt in the same way as “Front Seat Belt Inspection”.
• As to seat belts with A-ELR, check them as follows. – With vehicle at stop, pull seat belt all the way out, let it retract a little and try to pull it. It should not be
pulled out, that is, it should be locked where
retracted.
– Let seat belt retract to its original state. Next, pull it
half way out, let it retrac t a little and try to pull it
again. It should be pulled out smoothly, that is it
should not be locked at this time.

Precautions
Precautions on Service and Diagnosis of Air
Bag System
S7RS0B8200001
WARNING!
• 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 system activation.
• Do not modify the steering wheel, dashboard, both front seat or any other on
or around air bag system components.
Modifications can adversely affect air bag
system performance and lead to injury.
• Be sure to follow the procedures described in this section. Failure to follow
procedures could result in possible air bag
system activation, personal injury or
unneeded air bag system repairs.

• WARNING / CAUTION labels are attached on each
part of air bag system components (SDM, air bag
(inflator) modules and seat belt pretensioners). Be
sure to follow the instructions.
• Many of service procedures require disconnection of
“A/BAG” fuse and air bag (inflator) module(s) (driver,
passenger, side of both si des and curtain of both
sides) from initiator circuit to avoid an accidental
deployment.
• Do not apply power to the air bag system unless all components are connected or a diagnostic flow
requests it, as this will set a DTC.
• The “Air Bag Diagnostic S ystem Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning right operatio n and will lead you to the
correct flow to diagnose any air bag malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements. • Never use air bag component parts from another
vehicle.
• If the vehicle will be exposed to temperatures over 93
° C (200 °F) (for example, during a paint baking
process), remove the air bag system components
beforehand to avoid component damage or
unintended system activation.
• When handling the air bag (inflator) modules (driver, passenger, side of both si des and curtain of both
sides), seat belt pretensio ners (driver and passenger),
SDM, forward-sensor or side-sensor, be careful not to
drop it or apply an impact to it. If an excessive impact
was applied (e.g., SDM, forward-sensor and side-
sensor are dropped, air bag (inflator) module is
dropped from a height of 90 cm (3 ft) or more, seat
belt pretensioner (retractor assembly) is dropped from
a height of 30 cm (1 ft) or more), never attempt
disassembly or repair but replace it with a new one.
• When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver, passenger,
side of both sides and curtain of both sides) and seat
belt pretensioner connectors (driver and passenger)
respectively.
• When applying paint around the air bag system related parts, use care so that the harness or
connector will not be expo sed to the paint mist.
• Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
WARNING!
When performing service on or around air
bag system components or air bag wiring,
follow the procedures listed in “Disabling Air
Bag System” to temporarily disable the air
bag system.
Failure to follow procedures could result in
possible air bag system activation, personal
injury or unneeded air bag system repairs.

NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.
