Seat Belt Pretensioner System
(for front seat belt only)
52D011
Your vehicle is equipped with a seat belt
pretensioner system at the front seating
positions. You can use the pretensioner
seat belts in the same manner as ordinary
seat belts.
The seat belt pretensioner system works
with the SUPPLEMENTAL RESTRAINT
SYSTEM (advanced air bags). The crash
sensors and the electronic controller of the
air bag system also control the seat belt
pretensioners. The pretensioners are trig-
gered only when there is a frontal crash
severe enough to trigger the front air bags
and the seat belts are fastened. If the seat
belts are not fastened, the respective pre-
tensioner system will not be activated. For
precautions and general information
including servicing the pretensioner sys-
tem, refer to the “Supplemental Restraint
System (air bags)” section in addition to
this “Seat Belt Pretensioner System” sec-
tion, and follow all those precautions.
The pretensioner is located in each front
seat belt retractor. The pretensioner tight-
ens the seat belt so the belt fits the occu-
pant’s body more snugly in the event of a
frontal crash. The retractors will remain
locked after the pretensioners are acti-
vated. Upon activation, some noise will
occur and some smoke may be released.
These conditions are not harmful and do
not indicate a fire in the vehicle.
WARNING
Failure to follow these instructions
may increase the risk of injury in a
crash.
 Only use an extender for the per-
son, vehicle and seating position it
was provided for.
 Do not use if open end of
extender’s buckle is within 152 mm
(6 inches) of center of occupant’s
body (See diagram).
 Remove and stow the extender
when it is not being used.
WARNING
This section of the owner’s manual
describes your SUZUKI’s SEAT BELT
PRETENSIONER SYSTEM. Please
read and follow ALL these instruc-
tions carefully to minimize your risk
of severe injury or death.

Driver’s Seat Position SensorThe driver’s seat is equipped with a seat
position sensor to monitor the driver seat
fore/aft position. The seat position sensor
provides information which is used to
judge if the driver’s front air bag should
deploy at reduced power or at full power.
When the seat position sensor has a prob-
lem, the AIR BAG light on the instrument
cluster will turn on. If this happens, deploy-
ment of the driver’s front air bag will not
include consideration of seat fore/aft posi-
tion. Have the air bag system inspected by
an authorized SUZUKI dealer as soon as
possible.
Front Passenger’s Seat Belt Buckle
SensorThe front passenger’s seat belt buckle is
equipped with a sensor to monitor whether
or not the front passenger’s seat belt is fas-
tened. The front passenger’s seat belt
buckle sensor provides information which
is used to judge if the front passenger’s air
bag should deploy at reduced power or at
full power.
WARNING
An air bag supplements, or adds to,
the crash protection offered by seat
belts. The driver and all passengers
must be properly restrained by wear-
ing seat belts at all times, whether or
not air bags are mounted at their
seating position, to minimize the risk
of severe injury or death in the event
of a crash.
WARNING
If the AIR BAG light in the instrument
cluster ever comes on and stays on,
it means that something may be
wrong with the air bag system. If this
ever happens, have the vehicle ser-
viced immediately, because the air
bags may not offer the protection for
which they were designed.
CAUTION
Do not put any cargo or metal objects
under the seat. The seat position sen-
sor may not work properly or may be
damaged if it is covered with some-
thing.
WARNING
When the buckle sensor has a prob-
lem, the AIR BAG light on the instru-
ment cluster will turn on. If this
happens, deployment of the front
passenger’s air bag will not include
consideration of whether the front
passenger’s seat belt is fastened or
not. Have the air bag system
inspected by an authorized SUZUKI
dealer as soon as possible.

According to accident statistics, children
are safer when properly restrained in rear
seating positions than in front seating posi-
tions. Whenever possible, SUZUKI recom-
mends you install child restraints in the
rear seat.
The front passenger sensing system is
designed to enable the front passenger’sfront air bag when the system senses a
properly-seated adult in the front passen-
ger’s seat. When the passenger sensing
system has allowed the air bag to be
enabled, the “PASS AIR BAG OFF” indica-
tor will remain off to remind you that the air
bag is active.
If a person of adult size is sitting in the
front passenger’s seat and the “PASS AIR
BAG OFF” indicator comes on, it could be
because that person isn’t sitting properly in
the seat. If this happens, unfasten the seat
belts, sit upright in the center of the seat
with the seatback nearly vertical and your
legs outstretched, and refasten the seat
belt.
52D258
When seated as shown in the above illus-
tration, the front passenger sensing sys-
tem senses a properly-seated occupant
and enables the air bag.When using a seat belt extender, follow the
instructions in the “Seat Belt Extender”
section.
WARNING
Do not install a rear-facing child
restraint in the front passenger’s
seat. If the passenger’s front air bag
inflates, a child in a rear-facing child
restraint could be seriously injured.
The back of a rear-facing child
restraint would be too close to the
inflating air bag.
WARNING
Do not place any heavy objects on
the front passenger’s seat. The pres-
sure sensors in the sensor mat could
be damaged and the front passenger
sensing system may not work prop-
erly.
WARNING
The front passenger sensing system
may not work properly in the follow-
ing situations:
 The occupant is sitting near the
dashboard or is not sitting in the
proper position.
 Objects placed under the seat are
pushing up on the seat cushion.
WARNING
If the “PASS AIR BAG OFF” indicator
on the instrument panel turns on
even though there is no occupant or
an adult occupant in the front pas-
senger’s seat, it means that some-
thing may be wrong with the
passenger sensing system. Have the
system inspected by an authorized
SUZUKI dealer as soon as possible.

BEFORE DRIVING

How the System WorksIn a frontal collision, the crash sensors will
detect rapid deceleration and send a signal
to the controller. If the controller judges
that the deceleration represents a severe
frontal crash, the controller will trigger the
inflators. The controller also judges:
 Whether the front air bags should deploy
at reduced power or at full power accord-
ing to crash severity.
 Whether the air bags should deploy at
reduced power or at full power according
to crash severity, driver’s seat fore/aft
position and whether or not the front
passenger’s seat belt is fastened.
 Whether the front passenger’s front air
bag should deploy or not based on clas-
sification of the occupant of the front
passenger’s seat.
Since your vehicle is equipped with side air
bags, and side curtain air bags, crash sen-
sors will detect a side collision, and if the
controller judges that the side collision is
severe enough, it will trigger the side air
bag and side curtain air bag inflators.
The inflators inflate the appropriate air
bags with nitrogen or argon gas. The
inflated air bags provide a cushion for your
head (front air bags and side curtain air
bags only) and upper body. The air bag
inflates and deflates so quickly that you
may not even realize that it has activated.
The air bag will neither hinder your view
nor make it harder to exit the vehicle.Air bags must inflate quickly and forcefully
in order to reduce the chance of serious or
fatal injuries. However, an unavoidable
consequence of the quick inflation is that
the air bag may irritate bare skin, such as
the facial area against a front air bag. Also,
upon inflation, a loud noise will occur and
some powder and smoke will be released.
These conditions are not harmful and do
not indicate a fire in the car. Be aware,
however, that some air bag components
may be hot for a while after inflation.
A seat belt helps keep you in the proper
position for maximum protection when an
air bag inflates. Adjust your seat as far
back as possible while still maintaining
control of the vehicle. Sit fully back in your
seat; sit up straight; do not lean over the
steering wheel or dashboard. Front occu-
pants should not lean on or sleep against
the door. Please refer to the “Seat Adjust-
ment” section and the “Seat Belts and
Child Restraint Systems” section in the
“BEFORE DRIVING” section for details on
proper seat and seat belt adjustments.
WARNING
 Do not spill any liquids on the seat.
Liquids can damage the sensors
under the front seat.
 Have the driver’s seat position sen-
sor and the front passenger’s sen-
sor mat inspected by your dealer
after a collision.
 Do not replace the front seats. If
you replace them, the air bags and
front passenger sensing system
may not work properly.
 Do not use a seat cover. If you use
a seat cover, the front passenger
sensing system may not work prop-
erly.

Note that even though your vehicle may be
moderately damaged in a collision, the col-
lision may not have been severe enough to
trigger the front, side, or side curtain air
bags to inflate. If your car sustains ANY
front-end or side damage, have the air bag
system inspected by an authorized
SUZUKI dealer to ensure it is in proper
working order.
Your vehicle is equipped with a diagnostic
module which records information about
the air bag system if the air bags deploy in
a crash. The module records information
about overall system status, which sensors
activated the deployment, and whether the
front seat belts were in use.Servicing the Air Bag SystemIf the air bags inflate, have the air bags and
related components replaced by an autho-
rized SUZUKI dealer as soon as possible.
If your vehicle ever gets in deep water and
the driver’s floor is submerged, the air bag
controller could be damaged. If this hap-
pens, have the air bag system inspected
by the SUZUKI dealer as soon as possible.
Special procedures are required for servic-
ing or replacing an air bag. For that reason,
only an authorized SUZUKI dealer should
be allowed to service or replace your air
bags. Please remind anyone who services
your SUZUKI that it has air bags.
WARNING
 The driver should not lean over the
steering wheel. The front passen-
ger should not rest his or her body
against the dashboard, or other-
wise get too close to the dash-
board. For vehicles with side air
bags and side curtain air bags,
occupants should not lean on or
sleep against the door. In these sit-
uations, the out-of-position occu-
pant would be too close to an
inflating air bag, and may suffer
severe injury.
 Do not attach any objects to, or
place any objects over, the steering
wheel or dashboard. Do not place
any objects between the air bag
and the driver or front passenger.
These objects may interfere with air
bag operation or may be propelled
by the air bag in the event of a
crash. Either of these conditions
may cause severe injury.
 For vehicles with side air bags, do
not place seat covers on the front
seats, because seat covers could
restrict the air bag’s inflation. Also,
do not place any cup holders or
other objects on the door, as these
objects could be propelled by the
air bag in the event of a crash.
Either of these conditions may
cause severe injury.

driver’s seat belt is buckled. After repeating
several times, the reminder will be can-
celed even if the driver’s seat belt remains
unbuckled.
For details about the seat belt reminder,
refer to “Seat Belts and Child Restraint
Systems” in the “BEFORE DRIVING” sec-
tion.AIR BAG Light
63J030
This light monitors inflators, crash sensors,
seat belt pretensioners, the front passen-
ger sensing system, and corresponding
electrical circuits.
This light blinks for several seconds when
the ignition switch is turned to the “ON”position so you can check if the light is
working. The light will come on and stay on
if there is a problem in the air bag system
or the seat belt pretensioner system.
Malfunction Indicator Light
65D530
Your vehicle has a computer-controlled
emission control system. A malfunction
indicator light is provided on the instrument
panel to indicate when it is necessary to
have the emission control system serviced.
The malfunction indicator light comes on
when the ignition switch is turned to the
“ON” position to let you know the light is
working and goes out when the engine is
started.If the malfunction indicator light comes on
or blinks when the engine is running, ser-
vice to the emission control system is nec-
essary. Bring the vehicle to your SUZUKI
dealer to have the emission control system
serviced right away and avoid hard accel-
eration until the service is performed.
NOTE:
If the fuel filler cap is not installed fully, the
electrical system gets wet (such as by driv-
ing through a deep puddle of water) or the
fuel tank gets nearly empty, the malfunc-
tion indicator light may come on. If so, the
light will go off after driving a few times
after the fuel filler cap is installed fully, the
electrical system dries out or the fuel tank
is filled.
WARNING
It is absolutely essential that the
driver and passengers wear their seat
belts at all times. Persons who are
not wearing seat belts have a much
greater risk of injury if an accident
occurs. Make a regular habit of buck-
ling your seat belt before putting the
key in the ignition.
WARNING
If the AIR BAG light does not blink
when the ignition switch is turned to
the “ON” position or stays on or
comes on when driving, the air bag
system or the seat belt pretensioner
system may not work properly. Have
both systems inspected by an autho-
rized SUZUKI dealer.
CAUTION
Continuing to drive the vehicle when
the malfunction indicator light is on
or blinking can cause permanent
damage to the vehicle’s emission
control system, and can affect fuel
economy and driveability.
