gerous move, since the passing vehicle
occupies the same lane as oncoming traf-
fic for several seconds. A miscalculation,
an error in judgment, or a brief surrender to
frustration or anger can suddenly put the
passing driver face to face with the worst of
all traffic accidents – the head-on collision.
So here are some tips for passing:
 “Drive ahead.” Look down the road, to
the sides and to crossroads for situa-
tions that might affect your passing pat-
terns. If you have any doubt whatsoever
about making a successful pass, wait for
a better time.
 Watch for traffic signs, pavement mark-
ings and lines. If you can see a sign up
ahead that might indicate a turn or an
intersection, delay your pass. A broken
center line usually indicates it’s all right
to pass (providing the road ahead is
clear). Never cross a solid line on your
side of the lane or a double solid line,
even if the road seems empty of
approaching traffic.
 Do not get too close to the vehicle you
want to pass while you’re awaiting an
opportunity. For one thing, following too
closely reduces your area of vision,
especially if you’re following a larger
vehicle. Also, you won’t have adequate
space if the vehicle ahead suddenly
slows or stops. Keep back a reasonable
distance.
 When it looks like a chance to pass is
coming up, start to accelerate but stay inthe right lane and don’t get too close.
Time your move so you will be increas-
ing speed as the time comes to move
into the other lane. If the way is clear to
pass, you will have a “running start” that
more than makes up for the distance you
would lose by dropping back. And if
something happens to cause you to can-
cel your pass, you need only slow down
and drop back again and wait for another
opportunity.
 If other vehicles are lined up to pass a
slow vehicle, wait your turn. But take
care that someone isn’t trying to pass
you as you pull out to pass the slow vehi-
cle. Remember to glance over your
shoulder and check the blind spot.
 Check your mirrors, glance over your
shoulder, and start your left lane change
signal before moving out of the right lane
to pass. When you are far enough ahead
of the passed vehicle to see its front in
your inside mirror, activate your right
lane change signal and move back into
the right lane. (Remember that your right
outside mirror is convex. The vehicle you
just passed may seem to be farther away
from you than it really is.)
 Try not to pass more than one vehicle at
a time on two-lane roads. Reconsider
before passing the next vehicle.
 Don’t overtake a slowly moving vehicle
too rapidly. Even though the brake lamps
are not flashing, it may be slowing down
or starting to turn. If you’re being passed, make it easy for
the following driver to get ahead of you.
Perhaps you can ease a little to the right.
Loss of ControlLet’s review what driving experts say about
what happens when the three control sys-
tems (brakes, steering and acceleration)
don’t have enough friction where the tires
meet the road to do what the driver has
asked.
In any emergency, don’t give up. Keep try-
ing to steer and constantly seek an escape
route or area of less danger.
Skidding
In a skid, a driver can lose control of the
vehicle. Defensive drivers avoid most skids
by taking reasonable care suited to exist-
ing conditions, and by not “overdriving”
those conditions. But skids are always pos-
sible.
The three types of skids correspond to
your vehicle’s three control systems. In the
braking skid, your wheels aren’t rolling. In
the steering or cornering skid, too much
speed or steering in a curve causes tires to
slip and lose cornering force. And in the
acceleration skid, too much throttle causes
the driving wheels to spin.
A cornering skid is best handled by easing
your foot off the accelerator pedal.
If your vehicle starts to slide, ease your
foot off the accelerator pedal and quickly

Tire Sidewall LabelingUseful information about a tire is molded
into its sidewall. The examples below show
a typical passenger car tire and a spare
tire sidewall.
Passenger Car Tire Example
A. Tire Size
The tire size is a combination of let-
ters and numbers used to define a
particular tire’s width, height, aspect
ratio, construction type and service
description. See the “Tire Size” illus-tration later in this section for more
detail.
B. Department of Transportation (DOT)
Code
The Department of Transportation
(DOT) code indicates that the tire is in
compliance with the U.S. Department
of Transportation Motor Vehicle
Safety Standards.
C. Tire Identification Number (TIN)
The letters and numbers following the
DOT code are the Tire Identification
Number (TIN). The TIN shows the
manufacturer and plant code, tire size
and date the tire was manufactured.
The TIN is molded on to both sides of
the tire, although only one side may
have the date of manufacture.
D. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
E. Uniform Tire Quality Grading (UTQG)
Tire manufacturers are required to
grade tires based on three perfor-
mance factors: treadwear, traction
and temperature resistance.
F. Maximum Cold Inflation Load Limit
Maximum load that can be carried
and the maximum pressure needed to
support that load.
G. Load Index and Speed Rating
The two- or three-digit number is the
tire’s load index, the maximum load a
tire can carry at the speed indicated
by its speed symbol at the maximum
inflation pressure. The higher the
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.
 Underinflated 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.
 Overinflated 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.

ratio is “70”, as shown in item “C” of
the illustration, it would mean that thetire’s sidewall is 70% as high as it is
wide.
D. Construction Code
A letter code is used to indicate the
type of ply construction in the tire. The
letter “R” means radial ply construc-
tion, the letter “D” means diagonal or
bias ply construction; and the letter
“B” means belted-bias ply construc-
tion.
E. Rim Diameter
Diameter of the wheel in inches.
F. Service Description
These characters represent the load
range and the speed rating of a tire.
The load range represents the load
carrying capacity a tire is certified to
carry. The speed rating is the maxi-
mum speed a tire is certified to carry
a load. Speed ratings range from “A”
to “Z”.
Glossary of Tire TerminologyAir Pressure:
The amount of air inside the tire pressing
outward on each square inch of the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight:
This means the combined weight of
optional accessories. Some examples of
optional accessories are automatic trans-
mission, power steering, power brakes,
power windows, power seats, and air con-
ditioning.
Aspect Ratio:
The relationship of a tire’s height to its
width.
Belt:
A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other
reinforcing materials.
Bead:
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Bias Ply Tire:
A pneumatic tire in which the plies are laid
at alternate angles less than 90 degrees to
the centerline of the tread.

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 underinflated.
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.
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
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.

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 treadwear 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.
 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.
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

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:
Treadwear 200 Traction AA Temperature
A
The following information relates to the
system developed by the United States
National Highway Traffic Safety Adminis-
tration, which grades tires by treadwear,
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.
Treadwear
The treadwear 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
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 sudden
tire 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
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.
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.

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.See “Changing a Flat Tire” in this section

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.
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.
