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.
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
Changes or modifications expressly
approved by the party responsible for
compliance could void the user’s
authority to operate the equipment.

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

 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.
Tires:

5-37 SERVICE AND APPEARANCE CARE

 The tread or sidewall is cracked, cut or
snagged deep enough to show cord or
fabric.
 The tire has a bump, bulge or split.
 The tire has a puncture, cut or other
damage that can’t be repaired well
because of the size or location of the
damage.Buying New TiresTo find out what kind and size of tires you
need, look at the Tire and Loading Infor-
mation label.
Make sure the replacements are the same
size, load range, speed rating and con-
struction type (bias, bias-belted or radial)
as your original tires.
Uniform Tire Quality GradingQuality grades can be found where appli-
cable on the tire sidewall between the
tread shoulder and the maximum section
width. For example:
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.
CAUTION
Replacing the original tires with tires
of a different size may result in false
speedometer or odometer readings.
Check with your SUZUKI dealer
before purchasing replacement tires
that differ in size from the original
tires.

relative performance of tires depends upon
the actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road charac-
teristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
Temperature – A, B, C
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to suddentire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard No.109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Wheel Alignment and Tire BalanceThe wheels on your vehicle were aligned
and balanced carefully at the factory to
give you the longest tire life and best over-
all performance.
Scheduled wheel alignment and wheel bal-
ancing are not needed. However, if you
notice unusual tire wear or your vehicle
pulling one way or the other, the alignment
may need to be reset. If you notice your
vehicle vibrating when driving on a smooth
road, your wheels may need to be rebal-
anced.
Wheel ReplacementReplace any wheel that is bent, cracked or
badly rusted or corroded. If wheel nuts
keep coming loose, the wheel, wheel bolts
and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your SUZUKI dealer if
any of these conditions exist.
Your SUZUKI dealer will know the kind of
wheel you need.
Each new wheel should have the same
load-carrying capacity, diameter, width, off-
set and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them
only with new SUZUKI original equipment
parts. This way, you will be sure to have
the right wheel, wheel bolts and wheel nuts
for your vehicle.
WARNING
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, underinflation, or exces-
sive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
WARNING
Using the wrong replacement wheels,
wheel bolts or wheel nuts on your
vehicle can be dangerous. It could
affect the braking and handling of
your vehicle, make your tires lose air
and make you lose control. You could
have a collision in which you or oth-
ers could be injured. Always use the
correct wheel, wheel bolts and wheel
nuts for replacement.

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.

the jack to change a tire.Removing the Spare Tire and Tools
A. Jack
B. Wrench
C. Jack Handle
D. Screwdriver
The compartment spare tire and tools
you’ll need are located in the trunk.
1) Remove the trim cover from the floor of
the cargo area by pulling up on the tab.
2) Remove the foam tray that contains the
tools.
3) Turn the retainer on the compact spare
tire counterclockwise and remove the
retainer.
WARNING
Changing a tire can cause an injury.
The vehicle can slip off the jack and
roll over you or other people. You and
they could be severely injured. Find a
level place to change your tire. To
help prevent the vehicle from mov-
ing:
1) Set the parking brake firmly.
2) Put an automatic transmission
shift lever in PARK (P), or shift a
manual transmission to FIRST (1)
or REVERSE (R).
3) Turn off the engine and do not
restart while the vehicle is raised.
4) Do not allow passengers to
remain in the vehicle.
To be even more certain the vehicle
won’t move, you should put blocks at
the front and rear of the tire farthest
away from the one being changed.
That would be the tire on the other
side, at the opposite end of the vehi-
cle.
WARNING
Only use the jack for lifting this car
during an emergency tire change.
