cated by the system before any problem is
apparent. This may prevent more serious
damage to your vehicle. This system is
also designed to assist your service techni-
cian in correctly diagnosing any malfunc-
tion.
When the ignition is on, this light should
come on and should go out after a few sec-
onds as a check to show you it is working.
If the light doesn’t come on, have it
repaired.This light will also come on during a mal-
function in one of two ways:
Light Flashing
A misfire condition has been detected. A
misfire increases vehicle emissions and
may damage the emission control sys-
tem on your vehicle. Diagnosis and ser-
vice may be required.
Light On Steady
An emission control system malfunction
has been detected on your vehicle. Diag-
nosis and service may be required.
If the Light Is Flashing
The following may prevent more serious
damage to your vehicle:
 Reducing vehicle speed.
 Avoiding hard accelerations.
 Avoiding steep uphill grades.
If the light stops flashing and remains on
steady, see “If the Light Is On Steady” fol-
lowing.
If the light continues to flash, when it is
safe to do so, stop the vehicle. Find a safe
place to park your vehicle. Turn the key off,
wait at least 10 seconds and restart the
engine. If the light remains on steady, see
“If the Light Is On Steady” following. If the
light is still flashing, see your SUZUKI
dealer for service as soon as possible. Fol-
low the driving guidelines described above.If the Light Is On Steady
You also may be able to correct the emis-
sion system malfunction by considering the
following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to
fully install the cap. See “Filling Your Tank”
in section 5. The diagnostic system can
determine if the fuel cap has been left off
or is improperly installed. A loose or miss-
ing fuel cap will allow fuel to evaporate into
the atmosphere. A few driving trips with the
cap properly installed should turn the light
off.
Did you just drive through a deep puddle of
water?
If so, your electrical system may be wet.
The condition will usually be corrected
when the electrical system dries out. A few
driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with qual-
ity fuel. See “Gasoline Octane” in section
5. Poor fuel quality will cause your engine
not to run as efficiently as designed. You
may notice stalling after start-up, stalling
when you put the vehicle into gear, misfir-
ing, hesitation on acceleration or stumbling
on acceleration. (These conditions may go
away once the engine is warmed up.) This
will be detected by the system and cause
the light to turn on.
CAUTION
If you keep driving your vehicle with
this light on, your emission controls
may not work as well, your fuel econ-
omy may not be as good, and your
engine may not run as smoothly. This
could lead to costly repairs that may
not be covered by your warranty.
CAUTION
Modifications made to the engine,
transmission, exhaust or intake or
fuel system of your vehicle can affect
your vehicle’s emission controls and
may cause this light to come on.
Modifications to these systems could
lead to costly repairs not covered by
your warranty. This may also result in
a failure to pass a required Emission
Inspection/Maintenance test.
Warning Lights, Gauges and Indicators:

4-13 DRIVING YOUR VEHICLE
85Z03-03E
 As you go over the top of a hill, be alert.
There could be something in your lane,
like a stalled car or an accident.
 You may see highway signs on moun-
tains that warn of special problems.
Examples are long grades, passing or
no-passing zones, a falling rocks area or
winding roads. Be alert to these and take
appropriate action.Winter DrivingHere are some tips for winter driving:
 Have your vehicle in good shape for win-
ter.
 You may want to put winter emergency
supplies in your trunk.Include an ice scraper, a small brush or
broom, a supply of windshield washer fluid,
a rag, some winter outer clothing, a small
shovel, a flashlight, a red cloth and a cou-
ple of reflective warning triangles. And, if
you will be driving under severe conditions,
include a small bag of sand, a piece of old
carpet or a couple of burlap bags to help
provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your
tires meet the road probably have good
traction.
However, if there is snow or ice between
your tires and the road, you can have a
very slippery situation. You’ll have a lot
less traction or “grip” and will need to be
very careful.Very cold snow or ice can be slick and hard
to drive on. But wet ice can be even more
trouble because it may offer the least trac-
tion of all. You can get wet ice when it’s
about freezing (32°F; 0°C) and freezing
rain begins to fall. Try to avoid driving on
wet ice until salt and sand crews can get
there.
Whatever the condition – smooth ice,
packed, blowing or loose snow – drive with
caution.
Accelerate gently. Try not to break the frag-
ile traction. If you accelerate too fast, the
drive wheels will spin and polish the sur-
face under the tires even more.
Unless you have an anti-lock braking sys-
tem, you’ll want to brake very gently, too. (If
you do have anti-lock, see “Braking” in this
section. This system improves your vehi-

This (A) is where you add oil. See “Engine
Compartment Overview” on a previous
page in this section for more information
on location.
Be sure to add enough oil to put the level
somewhere in the proper operating range.
Push the dipstick all the way back in when
you’re through.What Kind of Engine Oil to Use
Oils recommended for your vehicle can be
identified by looking for the starburst sym-
bol.
This symbol indicates that the oil has been
certified by the American Petroleum Insti-
tute (API). Do not use any oil which does
not carry this starburst symbol.
If you choose to perform the engine oil
change service yourself, be sure the oil
you use has the starburst symbol on the
front of the oil container. If you have your
oil changed for you, be sure the oil put into
your engine is American Petroleum Insti-
tute certified for gasoline engines.
You should also use the proper viscosity oil
for your vehicle, as shown in the viscosity
chart. SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is the only viscosity grade recom-
mended for your vehicle. However, if it’s
going to be –4°F (–20°C) or above and
SAE 5W-30 is not available, you may use
SAE 10W-30.
These numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oil such as SAE 10W-40
or SAE 20W-50 under any conditions.

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 the date the tire was manufac-
tured. The TIN is molded on to both
sides of the tire, although only one
side may have the date of manufac-
ture.
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 maximuminflation pressure. The higher the
number is, the greater the load carry-
ing capacity. The letter symbol
denotes the speed at which a tire is
designed to be driven for extended
periods of time. (Ratings are listed
below.)
*The letters ZR may be used on tires with a
maximum speed capability over 149 mph
and will always be used on tires with a
maximum speed capability over 186 mph.Compact Spare Tire Example
A. Temporary Use Only Marking
The compact spare tire should not be
driven at speeds over 50 mph (80 km/
h). The compact spare tire is for
emergency use when a regular road
tire has lost air and gone flat. See
“Compact Spare Tire” and “If a Tire
Goes Flat” in this section.
B. Tire Ply Material
The type of cord and number of plies
in the sidewall and under the tread.
C. Tire Identification Number (TIN)

 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.
