Downloaded from www.Manualslib.com manuals search engine 00-3 Precautions:
WARNING!
SDM
• For handling and storage of a SDM, select
a place where the ambient temperature
below 65 °C (150 °F), without high humidity
and away from electric noise.
• During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM). Never strike or jar the SDM.
• Never power up the air bag system when
the SDM is not rigidly attached to the
vehicle. All SDM and mounting bracket
fasteners must be carefully torqued and
the arrow must be pointing toward the
front of the vehicle to ensure proper
operation of the air bag system.
The SDM could be activated when powered
while not rigidly attached to the vehicle
which could cause deployment and result
in personal injury.

WARNING!
Driver and Passenger Seat Belt
Pretensioners
• For handling and storage of a live seat belt
pretensioner, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Never carry seat belt pretensioner by wire
or connector of pretensioner. When
placing a live seat belt pretensioner on the
workbench or some place like that, never
put something on seat belt pretensioner.
Otherwise, personal injury may result.
• Never dispose of live (inactivated) seat belt
pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” before disposal.
• The seat belt pretensioner immediately
after activation is very hot. Wait for at least
half an hour to cool it off before
proceeding the work.
• With many service procedures, gloves and
safety glasses should be worn to prevent
any possible irritation of the skin or eyes.

• Even when the accident was light enough not to
cause air bags to activate, be sure to inspect system
parts and other related parts according to instructions
under “Repair and Inspection Required after Accident
in Section 8B”.
• When servicing parts other than air bag system, if
shocks may be applied to air bag system component
parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver,
passenger, side and curtain), seat belt pretensioners
(driver and passenger), forward sensor, side sensors
or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied, never attempt
disassembly or repair but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got
onto air bag (inflator) modules (driver, passenger, side
and curtain) or seat belt pretensioners (drive and
passenger), wipe off immediately with a dry cloth.
• Air bag wire harness is included in floor and
instrument panel wire harnesses. Air bag wire
harness branched off from floor and instrument panel
wire harnesses can be identified easily as it is covered
with a yellow protection tube and it has yellow
connectors. Be very careful when handling it.
• 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.
• 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.
• Never use air bag system component parts from
another vehicle.
• When using electric welding, be sure to disconnect all
air bag (inflator) module connectors and pretensioner
connectors from air bag wire harness respectively.
• Never expose air bag system component parts
directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each
part of air bag system components. Be sure to follow
the instructions.
• After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check in Section 8B”.
General PrecautionsS6RW0D0000002
The WARNING and CAUTION describe some general
precautions that you should observe when servicing a
vehicle. These general precautions apply to many of the
service procedures, and they will not necessarily be
repeated with each procedure to which they apply.

Precautions on Fuel System ServiceS6RW0D1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot
heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pressure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the
risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each
hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing injector or fuel feed pipe, lubricate its O-ring with gasoline.
• When servicing the fuel tank, it should be treated with respect, with no contact with sharp edges or
hot surfaces. In addition, the fuel tank should not be dropped since fuel tank, fuel pump and other
components can be damaged by the impact. If dropped, all components should be replaced because
there is a risk of damage.
• The fuel tank is made of resin.
Be sure not to allow solvent (chemical article such as grease and sealant) to attach to the fuel tank
as some chemical reaction may occur, causing the fuel tank to be swollen, hardened or distorted
leakage and resulting in fuel leakage from the fuel tank.

Seat Belt with ELR
The seat belt with emergency locking retractor (ELR) is
designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any
further) when any of the following items is detected as
exceeding each set value;
• Speed at which the webbing is pulled out of the
retractor.
• Acceleration or deceleration of the vehicle speed.
• Inclination.
Seat Belt with A-ELR
The automatic and emergency locking retractor (A-ELR)
works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an
Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out
from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further,
unless it is wound all the way back into the retractor,
which releases the lock and allows the webbing to be
pulled out.
Seat Belt with ELR and Pretensioner
The seat belt with ELR and a pretensioner has a
pretensioner mechanism which operates in linkage with
the air bag in addition to the described ELR.The pretensioner is incorporated in retractor and
controlled by SDM as one of air bag system
components. It will be activated at the same time as the
driver and passenger air bag module when an impact at
the front of vehicle exceeds the specified value.
When servicing seat belt (retractor) with pretensioner, be
sure to observe all WARNINGS and CAUTIONS and
“Precautions on Service and Diagnosis of Air Bag
System in Section 8B”.
CAUTION!
Do not reuse the seat belt pretensioner
(retractor) that has activated. Replace it with
a new seat belt and buckle together as a set.
For checking procedure of its activation,
refer to “Repair and Inspection Required after
Accident in Section 8B”.

Seat Belt Remainder
When driver’s seat belt is unfastened (under the
following conditions), seat belt reminder light inform that
driver’s seat belt is unfastened. Seat belt reminder light
located in combination meter located inside BCM
operate as follows:
• Seat belt reminder light comes on when driver’s seat
belt is unfastened while ignition key switch is at ON
position.

Precautions
Precautions on Service and Diagnosis of Air
Bag System
S6RW0D8200004
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/B” fuse and air bag (inflator) module(s) (driver
module, passenger module, side modules and curtain
modules) 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 System Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning light operation 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
module, passenger module, side modules and curtain
modules), seat belt pretensioners (driver module and
passenger module), SDM, forward impact-sensor or
side impact-sensor be careful not to drop it or apply
an impact to it. If an excessive impact was applied
(e.g., SDM, forward impact-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 module,
passenger module, side modules and curtain
modules) and seat belt pretensioner connectors
(driver module and passenger module) respectively.
• When applying paint around the air bag system
related parts, use care so that the harness or
connector will not be exposed 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.
