Tire Pressure Monitoring
SystemIf your vehicle is equipped with a tire pres-
sure monitoring system, it uses pressure
sensors containing a unique identification
code to monitor the inflation pressure of
the tires. When the inflation pressure of
one or more tires indicates significant
under-inflation, the tire pressure warning
light comes on. If the warning light blinks,
for approximately one minute and then illu-
minates continuously, the monitoring sys-
tem may not be working. For more
information, see “Tire Pressure Monitoring
System Warning Light” in section 3.
The tire pressure monitoring system does
not replace normal tire maintenance. See
“Inflation – Tire Pressure & Correcting the
Tire Pressure” in this section for more
information.
The tire pressure warning light can come
on due to normal causes such as natural
air leaks and pressure changes caused by
changes in temperature or atmospheric
pressure. Adjusting the air pressure in the
tires to the pressure shown on the tire and
loading information label should cause the
tire pressure warning light to turn off.
If you use new wheels with new tire infla-
tion pressure sensors, their ID codes must
be programmed into the tire pressure mon-
WARNING
If the tire pressure warning light does
not come on when the ignition is
turned to the “ON” position, or
comes on and blinks while driving
there may be a problem with the tire
pressure monitoring system. Have
your vehicle inspected by an autho-
rized dealer.
WARNING
If the tire pressure warning light
comes on and stays on, reduce your
speed and avoid abrupt steering and
braking. Stop in a safe place as soon
as possible and check your tires.
 If you have a flat tire, replace it with
a spare tire. Refer to “Changing a
Flat Tire” in section 5.
 If one or more of your tires is
under-inflated, adjust the inflation
pressure in all of your tires to the
recommended inflation pressure as
soon as possible.
Be aware that driving on a signifi-
cantly under-inflated tire can cause
the tire to overheat and can lead to
tire failure, and may affect steering
control and brake effectiveness. This
could lead to an accident, resulting in
severe injury or death.
CAUTION
 Do not use liquid sealants for a flat
tire as air pressure sensors can be
damaged.
 In case of tire a bursting or sudden
pressure drops, the tire pressure
monitoring system warning light
may not come on immediately.
 The inflation pressures vary with
the ambient temperature. If the
vehicle is subjected to large varia-
tions in ambient temperature, the
tire
inflation pressure may be
under-inflated when the ambient
temperature is relatively low. If the
warning light comes on, adjust the
tire inflation pressure.
 The tire pressure sensors can be
damaged by the installation or
removal of tires. When tires must
be repaired or replaced, we highly
recommend that you have them
repaired or replaced by your
SUZUKI dealer.
 If the tire pressure warning light
comes on or blinks frequently,
there may be something wrong
with one of the tires or with the
monitoring system. Have your vehi-
cle inspected by your SUZUKI
dealer.

itoring system. Have tire and wheel
replacement performed by an authorized
service facility to avoid the risk of damag-
ing the tire pressure monitor sensors.
The tire pressure monitoring system may
not work normally in the following circum-
stances:
 Wheels other than genuine wheels are
being used.
 Wheels whose ID codes are not memo-
rized by the vehicle are used. The moni-
toring system should be set up by an
authorized service facility.
 Wheels that are not fitted with tire pres-
sure sensors are being used.
 The tire inflation pressure sensors’ bat-
tery is exhausted.
 A wireless facility or device using the
same frequency is near the vehicle.
 Snow or ice is stuck inside the fenders
and/or on the wheels.
The tire pressure monitoring system oper-
ates on a radio frequency subject to Fed-eral Communications Commission (FCC)
Rules and with Industry and Science Can-
ada.
This device complies with Part 15 of the
FCC Rules and with RSS-210 of Industry
and Science Canada. Operation is subject
to the following two conditions: (1) This
device may not cause harmful interference,
and (2) this device must accept any inter-
ference received including interference that
may cause undesired operation of the
device.
NOTE:
Changes or modifications not expressly
approved by the party responsible for com-
pliance could void the user’s authority to
operate the equipment.
NOTE:
Only use tire sizes that are recommended
for your vehicle. Use of inappropriate-size
tires can cause a variety of problems which
will not be covered under warranty.
Correcting the Tire PressureTo permanently eliminate the low tire pres-
sure warning light, you must fill the tires
with the correct amount of air. However, at
the next vehicle start-up, the warning light
will reappear if the tire pressure is not cor-
rected. The best time to check your tire
pressure is when the tires are cold. A Tire
and Loading Information label, located on
the driver’s door near the door latch, shows
the correct inflation pressure for the tires
when they are cold. Cold means your vehi-
cle has been sitting for at least three hours
or driven no more than one mile. You may
notice during cooler conditions that low tire
pressure warning light will appear when
the vehicle is first started and then turn off
as you start to drive the vehicle. This could
be an early indicator that your tire pres-
sures are getting low and need to be
inflated to the proper pressure.
WARNING
Only use tires and wheels recom-
mended by us as standard or
optional equipment for your vehicle.
Use of tires or wheels not recom-
mended by us can result in TPMS fail-
ure. Refer to “Tires” in the “SERVICE
AND APPEARANCE CARE” section
for additional information.
WARNING
We highly recommend that any TPMS
sensor replacement or tire rotation
be done by an authorized Suzuki
dealer. The dealer will make sure that
the TPMS system is set up to recog-
nize the ID codes of the TPMS sen-
sors.

Tire Inflation PressureThe Tire and Loading Information label
shows the correct inflation pressures for
your tires when they’re cold. “Cold” means
your vehicle has been sitting for at least
three hours or driven no more than 1 mile
(1.6 km). See “Loading Your Vehicle” in
section 4.
When to Check
Check your tires each time you fill your fuel
tank or at least once a month using a tire
pressure gauge.
Don’t forget your compact spare tire. It
should be at 60 psi (420 kPa).
How to check
Use a good quality pocket-type gauge to
check tire pressure. You can’t tell if your
tires are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they’re under inflated.
Check the tire’s inflation pressure when the
tires are cold. Cold means your vehicle has
been sitting for at least three hours or
driven no more than 1 mile (1.6 km).Remove the valve cap from the tire valve
stem. Press the tire gauge firmly onto the
valve to get a pressure measurement. If
the cold tire inflation pressure is low, add
air until you reach the recommended pres-
sure.
If you overfill the tire, release air by push-
ing on the metal stem in the center of the
tire valve. Recheck the tire pressure with
the tire gauge.
Be sure to put the valve caps back on the
valve stems. They help prevent leaks by
keeping out dirt and moisture.
Tire Inspection and RotationInspect your vehicle’s tires at least once a
month.
Tires should be rotated every 7,500 miles
(12,000 km).
Any time you notice unusual wear, rotate
your tires as soon as possible and check
wheel alignment. Also check for damaged
tires or wheels. See “When It Is Time for
New Tires” and “Wheel Replacement” in
this section for more information.
The purpose of regular rotation is to
achieve more uniform wear for all tires on
the vehicle. The first rotation is the most
important. See “Scheduled Maintenance
Services” in section 6, for scheduled rota-
tion intervals. Tire

WARNING
 Air pressures should be checked
when the tires are cold or you may
get inaccurate readings.
 Check the inflation pressure from
time to time while inflating the tire
gradually, until the specified pres-
sure is obtained.
(Continued)
WARNING
(Continued)
 Never underinflate or overinflate
the tires.
Underinflation can cause unusual
handling characteristics or can
cause the rim to slip on the tire
bead, resulting in an accident or
damage to the tire or rim.
Underinflation can also cause tires
to overheat, leading to tire failure.
Overinflation can cause the tire to
burst, resulting in personal injury.
Overinflation can also cause
unusual handling characteristics
which may result in an accident.

When rotating your tires, always use the
correct rotation pattern shown here.
Don’t include the compact spare tire in
your tire rotation.
After the tires have been rotated, adjust
the front and rear inflation pressures as
shown on the Tire and Loading Information
label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut
Torque” under “Capacities and Specifica-
tions” in this section.
Vehicle LoadingThe tires on your vehicle, when they are
inflated to the recommended tire inflation
pressure, have a load-carrying capacity
that is greater than the load that will be on
the tires when the vehicle is at its GVWR
or GAWR limit. Never use replacement
tires that have a load-carrying capacity
less than the original tires on your vehicle.
Tire load-carrying capacity information is
molded into the tire sidewall typically
shown as “Max. Load”. Use of replacement
tires with a lower load-carrying capacity
than the original tires, or failure to keep the
tires inflated to the recommended tire pres-
sure, may reduce the GVWR or GAWR
limit of your vehicle.NOTE:
Use of replacement tires with a higher
load-carrying capacity than the original
tires, or using a tire inflation pressure
higher than the recommended tire inflation
pressure, will not increase the GVWR or
GAWR limit of your vehicle.
When It Is Time for New TiresOne way to tell when it’s time for new tires
is to check the tread wear indicators, which
will appear when your tires have only 1/16
inch (1.6 mm) or less of tread remaining.
You need a new tire if any of the following
statements are true:
 You can see the indicators at three or
more places around the tire.
 You can see cord or fabric showing
through the tire’s rubber.
WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose after
a time. The wheel could come off and
cause an accident. When you change
a wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you can
use a cloth or a paper towel to do
this, but be sure to use a scraper or
wire brush later, if you need to, to get
all the rust or dirt off. See “Changing
a Flat Tire” in this section.

Compact Spare TireAlthough the compact spare tire was fully
inflated when your vehicle was new, it can
lose air after a time. Check the inflation
pressure regularly. It should be 60 psi (420
kPa).
After installing the compact spare tire on
your vehicle, you should stop as soon as
possible and make sure your compact
spare tire is correctly inflated. The compact
spare tire is made to perform well at
speeds up to 50 mph (80 km/h), so you
can finish your trip and have your full-size
tire repaired or replaced where you want.
Of course, it’s best to replace your spare
with a full-size tire as soon as you can.
Your spare will last longer and be in good
shape in case you need it again.
Don’t use your compact spare tire on other
vehicles.
And don’t mix your compact spare tire or
wheel with other wheels or tires. They
won’t fit. Keep your compact spare tire and
its wheel together.
CAUTION
When the compact spare Tire is
installed, don’t take your vehicle
through an automatic car wash with
guide rails. The compact spare can
get caught on the rails. That can
damage the tire and wheel, and
maybe other parts of your vehicle.
CAUTION
Tire chains won’t fit your compact
spare tire. Using them can damage
your vehicle and can damage the
chains too. Don’t use tire chains on
your compact spare.
WARNING
The compact spare tire and wheel are
intended for temporary emergency
use only. Continuous use of the com-
pact spare tire can result in tire fail-
ure and loss of control. Always
observe these precautions when
using the compact spare tire:
 Your vehicle will handle differently
with this temporary spare.
 Do not exceed 80 km/h (50 mph)
speed.
 Replace the compact spare tire
with a standard tire and wheel as
soon as possible.
 Use of the compact spare tire will
reduce ground clearance.
 Recommended air pressure for the
compact spare tire is 420 kPa (60
psi).
(Continued)
WARNING
(Continued)
 Do not use tire chains on the com-
pact spare tire. If you must use tire
chains, rearrange the wheels so
standard tires and wheels are fitted
to the front axle.
 The compact spare tire has a much
shorter tread life than the conven-
tional tires on your vehicle.
Replace the tire as soon as the
tread wear indicator appears.
 When replacing the compact spare
tire, use a replacement tire with the
exact same size and construction.

SUZUKI dealer. See “Vehicle Care/
Appearance Materials” later in this section.
Don’t use cleaning agents that are petro-
leum based, or that contain acid or abra-
sives. All cleaning agents should be
flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the fin-
ish with a soft, clean chamois or an all-cot-
ton towel to avoid surface scratches and
water spotting.
High pressure car washes may cause
water to enter your vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft
cloth and a car washing soap to clean
exterior lamps and lenses. Follow instruc-
tions under Washing Your Vehicle.
Finish Care
Occasional waxing or mild polishing of
your vehicle by hand may be necessary to
remove residue from the paint finish. You
can get SUZUKI-approved cleaning prod-
ucts from your SUZUKI dealer. See “Vehi-
cle Care/Appearance Materials” later in
this section.
Your vehicle has a “basecoat/clear coat”
paint finish. The clear coat gives more
depth and gloss to the colored basecoat.
Always use waxes and polishes that are
non-abrasive and made for a basecoat/
clear coat paint finish.Foreign materials such as calcium chloride
and other salts, ice melting agents, road oil
and tar, tree sap, bird droppings, chemicals
from industrial chimneys, etc., can damage
your vehicle’s finish if they remain on
painted surfaces. Wash the vehicle as
soon as possible. If necessary, use non-
abrasive cleaners that are marked safe for
painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to
aging, weather and chemical fallout that
can take their toll over a period of years.
You can help to keep the paint finish look-
ing new by keeping your vehicle garaged
or covered whenever possible.
Cleaning Windshield and Wiper Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade
chatters when running, wax, sap or other
material may be on the blade or wind-
shield.
Clean the outside of the windshield with a
full-strength glass cleaning liquid. The
windshield is clean if beads do not form
when you rinse it with water.Grime from the windshield will stick to the
wiper blades and affect their performance.
Clean the blades by wiping vigorously with
a cloth soaked in full-strength windshield
washer solvent. Then rinse the blades with
water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
Cleaning Aluminum Wheels
Keep your wheels clean using a soft clean
cloth with mild soap and water. Rinse with
clean water. After rinsing thoroughly, dry
with a soft clean towel. A wax may then be
applied.
The surface of these wheels is similar to
the painted surface of your vehicle. Don’t
use strong soaps, chemicals, abrasive pol-
ishes, abrasive cleaners, cleaners with
acid, or abrasive cleaning brushes on them
because you could damage the surface.
Do not use chrome polish on aluminum
wheels.
Don’t take your vehicle through an auto-
matic car wash that has silicone carbide
tire cleaning brushes. These brushes can
also damage the surface of these wheels.
Cleaning Tires
To clean your tires, use a stiff brush with
tire cleaner.
CAUTION
Machine compounding or aggressive
polishing on a basecoat/clearcoat
paint finish may dull the finish or
leave swirl marks.
