tire pressure monitoring system is func-
tioning properly.
Your vehicle has also been equipped with
a TPMS malfunction indictor to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.In this situation, please have the system
inspected by an authorized service facility.
If you replace one or more tires and the
TPMS warning light goes off during driv-
ing, there is no problem. However, if the
warning light does not go off, or if it flashes
again when the vehicle is driven, have the
vehicle inspected by an authorized service
facility.
WARNING
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label and
this manual. (If your vehicle has tires
of a different size than the size indi-
cated on the vehicle label or tire infla-
tion pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life and may
affect the vehicle’s handling and
stopping ability.
(Continued)
WARNING
(Continued)
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger illumi-
nation of the TPMS low tire pressure
telltale.
WARNING
If the tire pressure monitoring system
warning light does not illuminate
when the ignition key is turned to the
“ON” position, have the system
inspected by an authorized service
facility. If the warning light flashes
while driving, check to see whether
the warning light goes off after a few
minutes of driving.
WARNING
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunctions
may occur for a variety of reasons,
including the installation of replace-
ment or alternate tires or wheels on
the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

5) Clamp the steering wheel in a straight-
ahead position with a clamping device
designed for towing.
6) Release the parking brake.
Loading Your VehicleIt is very important to know how much
weight your vehicle can carry. The load
capacities of your vehicle are indicated by
the Gross Vehicle Weight Rating (GVWR),
the Gross Axle Weight Rating (GAWR,
front and rear), the total load capacity, the
seating capacity, and the cargo load
capacity. The GVWR and GAWR (front and
rear) are listed on the Safety Certification
Label which is located below the driver’s
side door latch striker. The total load
capacity and seating capacity are listed on
the Tire and Loading Information Label
which is located on the center pillar, near
the driver’s door latch.
The Tire and Loading Information label
also gives you the size and recommended
inflation pressure for the factory installed,
original equipment tires on your vehicle.
For more information on tires and inflation,
see “Tires” in section 5.Tire and Loading Information Label
Certification Label
The cargo load capacity can be deter-
mined as described below.
Cargo Load Capacity – Maximum weight
of cargo and luggage that the vehicle cansafely carry. Cargo load capacity is the dif-
ference between the total load capacity of
the vehicle and the total combined weight
of all vehicle occupants. Refer to “Steps for
Determining Correct Load Limit” for details
on how to determine cargo load capacity.
GVWR – Maximum permissible overall
weight of the fully loaded vehicle (including
all the occupants, accessories and cargo
plus the trailer tongue weight if towing a
trailer).
GAWR – (Front and Rear) Maximum per-
missible weight on an individual axle.
Seating Capacity – Maximum number of
occupants the vehicle is designed to carry.
NOTE:
Even though the number of occupants is
within the seating capacity, you still must
make sure that you do not exceed the total
load capacity of the vehicle.
Total Load Capacity – Maximum permissi-
ble weight a vehicle can carry including the
weight of all the occupants, accessories
and cargo.
The weight of any accessories already
installed on your vehicle at the time of pur-
chase, or that you or the dealer install after
purchase, must be subtracted from the
total load capacity to determine how much
capacity remains available for occupants
and cargo. Contact your SUZUKI dealer for
further information.

WARNING
Poorly maintained and improperly
used tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out
and a serious accident. See “Load-
ing Your Vehicle” in the Index.
 Under inflated tires pose the same
danger as overloaded tires. The
resulting accident could cause
serious injury. Check all tires fre-
quently to maintain the recom-
mended pressure. Tire pressure
should be checked when your tires
are cold.
 Overi nflated tires are more likely to
be cut, punctured or broken by a
sudden impact – such as when you
hit a pothole. Keep tires at the rec-
ommended pressure.

Tread wear 200 Traction AA Tempera-
ture A
The following information relates to the
system developed by the United States
National Highway Traffic Safety Adminis-
tration, which grades tires by tread wear,
traction and temperature performance.
(This applies only to vehicles sold in the
United States.) The grades are molded on
the sidewalls of most passenger car tires.
The Uniform Tire Quality Grading system
does not apply to deep tread, winter-type
snow tires, space-saver or temporary use
spare tires, tires with nominal rim diame-
ters of 10 to 12 inches (25 to 30 cm), or to
some limited-production tires.
While the tires available on SUZUKI vehi-
cles may vary with respect to these grades,
they all conform to federal safety require-
ments.
Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For
example, a tire graded 150 would wear one
and a half (1.5) times as well on the gov-
ernment course as a tire graded 100. The
WARNING
Your SUZUKI is equipped with tires
which are all the same type and size.
This is important to ensure proper
steering and handling of the vehicle.
Never mix tires of different size or
type on the four wheels of your vehi-
cle. The size and type of tires used
should be only those approved by
SUZUKI Motor Corporation as stan-
dard or optional equipment for your
vehicle.
WARNING
Replacing the wheels and tires
equipped on your vehicle with certain
combinations of aftermarket wheels
and tires can significantly change the
steering and handling characteris-
tics of your vehicle. Oversized tires
may also rub against the fender over
bumps, causing vehicle damage or
tire failure. Therefore, use only those
wheel and tire combinations
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle. For
information regarding the specified
tires, refer to the Tire Information
Label located on the driver’s side
door pillar or “Tire Inflation Pres-
sure” in this section.

Used Replacement Wheels
Tire Chains
If a Tire Goes FlatIt’s a unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tire properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blowout”, here
are a few tips about what to expect and
what to do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal
and grip the steering wheel firmly. Steer to
maintain lane position, and then gently
brake to a stop well out of the traffic lane.A rear blowout, particularly on a curve,
acts much like a skid and may require the
same correction you’d use in a skid. In any
rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under
control by steering the way you want the
vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
If a tire goes flat, the next part shows how
to use your jacking equipment to change a
flat tire safely.
Changing a Flat TireIf a tire goes flat, avoid further tire and
wheel damage by driving slowly to a level
place. Turn on your hazard warning flash-
ers.
CAUTION
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance and
tire or tire chain clearance to the
body and chassis.
WARNING
Putting a used wheel on your vehicle
is dangerous. You can’t know how it’s
been used or how far it’s been driven.
It could fail suddenly and cause a
crash. If you have to replace a wheel,
use a new SUZUKI original equip-
ment wheel.
CAUTION
Use tire chains only where legal and
only when you must. Use only SAE
class “S” type chains that are the
proper size for your tires. Install them
on the front tires and tighten them as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer’s
instructions. If you can hear the
chains contacting your vehicle, stop
and retighten them. If the contact
continues, slow down until it stops.
Driving too fast or spinning the
wheels with chains on will damage
your vehicle.
WARNING
Lifting a vehicle and getting under it
to do maintenance or repairs is dan-
gerous without the appropriate safety
equipment and training. The jack pro-
vided with your vehicle is designed
only for changing a flat tire. If it is
used for anything else, you or others
could be badly injured or killed if the
vehicle slips off the jack. Use the jack
provided with your vehicle only for
changing a flat tire.

Don’t try to put a wheel cover on your com-
pact spare tire. It won’t fit. Store the wheel
cover in the trunk until you have the flat tire
repaired or replaced.Storing the Flat Tire and Tools
Store the flat tire in the compact spare tire
compartment. Place the tire in the com-
partment, then secure the retainer. Store
the jack in its housing in the cargo area.
Secure the jack by turning the retainer
clockwise. Store the tools securely in the
foam tray and place the tray on top of the
tire. Replace the trim cover.
Storing the Spare Tire and Tools
The compact spare tire is for temporary
use only. Replace the compact spare tire
with a full-size tire as soon as you can. See
“Compact Spare Tire” in this section.
WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to come loose and even come
off. This could lead to an accident. Be
sure to use the correct wheel nuts. If
you have to replace them, be sure to
get new SUZUKI original equipment
wheel nuts. Stop somewhere as soon
as you can and have the nuts tight-
ened with a torque wrench to the
proper torque specification. See
“Capacities and Specifications” in
the Index for the wheel nut torque
specification.
CAUTION
Improperly tightened wheel nuts can
lead to brake pulsation and rotor
damage. To avoid expensive brake
repairs, evenly tighten the wheel nuts
in the proper sequence and to the
proper torque specification. See
“Capacities and Specifications” in
the index for the wheel nut torque
specification.
CAUTION
If you install a full-size tire rather than
your compact spare tire, reinstall the
wheel cover as follows:
1) Put the wheel cover on the full-
size tire.
2) Fasten the 4 plastic caps snugly
by hand.
3) Tighten the caps by turning them
an additional 90° with the wheel
wrench.
– The proper tightening torque is a
maximum of 5.9 lb-ft (8 N·m).
– Tightening to the improper
torque can cause damage to the
plastic caps.
CAUTION
Wheel covers will not fit on your com-
pact spare. If you try to put a wheel
cover on the compact spare, you
could damage the cover or the spare.
WARNING
Improperly storing a jack, a tire, or
other equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or col-
lision, loose equipment could strike
someone. Store all these items in the
