If you experience one or more of these
conditions, change the fuel brand you use.
It will require at least one full tank of the
proper fuel to turn the light off.
If none of the above steps have made the
light turn off, your SUZUKI dealer can
check the vehicle. Your SUZUKI dealer has
the proper test equipment and diagnostic
tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local govern-
ments have or may begin programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
Here are some things you need to know to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if
the Check Engine light is on or is not work-
ing properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system
determines that critical emission control
systems have not been completely diag-
nosed by the system. The vehicle would be
considered not ready for inspection. This
can happen if you have recently replaced
your battery or if your battery has run
down. The diagnostic system is designed
to evaluate critical emission control sys-tems during normal driving. This may take
several days of routine driving. If you have
done this and your vehicle still does not
pass the inspection for lack of OBD system
readiness, your SUZUKI dealer can pre-
pare the vehicle for inspection.
Oil Pressure LightIf you have a low engine oil pressure prob-
lem, this light will stay on after you start
your engine, or come on when you are
driving. This indicates that your engine is
not receiving enough oil.
The engine could be low on oil, or could
have some other oil problem. Have it fixed
immediately.
The oil light could also come on in three
other situations:
 When the ignition is on but the engine is
not running, the light will come on as a
check to show you it is working. The light
will go out after you start the engine. If it
doesn’t come on with the ignition on, you
may have a problem with the fuse or
bulb. Have it fixed right away. If you’re idling at a stop sign, the light
may blink on and then off.
 If you make a hard stop, the light may
come on for a moment. This is normal.
Fog Lamp LightIf your vehicle has this feature, the fog
lamps indicator light will come on when the
fog lamps are in use.
The light will go out when the fog lamps
are turned off.
WARNING
Don’t keep driving if the oil pressure
is low. If you do, your engine can
become so hot that it catches fire.
You or others could be burned. Check
your oil as soon as possible and have
your vehicle serviced.
CAUTION
Operating your engine with the low
oil pressure light on can result in
severe engine damage which is not
covered by your warranty.

ServiceYour SUZUKI dealer knows your vehicle
best and wants you to be happy with it. We
hope you’ll go to your SUZUKI dealer for
all your service needs. You’ll get genuine
SUZUKI parts and SUZUKI trained and
supported service people.
We hope you’ll want to keep your SUZUKI
vehicle all SUZUKI. Doing Your Own Service WorkYour vehicle has an air bag system. Before
attempting to do your own service work,
see “Servicing Your Air Bag-Equipped
Vehicle” in section 1.
You should keep a record with all parts
receipts and list the mileage and the date
of any service work you perform. See
“Maintenance Record” in section 6.
Adding Equipment to the Outside of
Your VehicleThings you might add to the outside of your
vehicle can affect the airflow around it. This
may cause wind noise and affect wind-
shield washer performance. Check with
your SUZUKI dealer before adding equip-
ment to the outside of your vehicle.
FuelUse of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.Gasoline OctaneUse only unleaded gasoline with a posted
octane rating of 87 or higher. In an emer-
gency, you may be able to use a lower
octane rating – as low as 85 – if heavy
knocking does not occur. Refill your tank
with proper fuel as soon as possible. Oth-
erwise, you might damage your engine. If
you are using 87 or higher-octane rating
fuel and you hear heavy knocking, your
engine needs service.California FuelIf your vehicle is certified to meet California
Emission Standards (see the underhood
emission control label), it is designed to
operate on fuels that meet California spec-
ifications. If this fuel is not available in
states adopting California emissions stan-
dards, your vehicle will operate satisfacto-
rily on fuels meeting federal specifications,
but emission control system performance
may be affected. The malfunction indicator
lamp may turn on (see Malfunction Indica-
tor Lamp in section 3) and your vehicle
may fail a smog-check test. If this occurs,
return to your SUZUKI dealer for diagno-
sis.
WARNING
You can be injured and your vehicle
could be damaged if you try to do
service work on a vehicle without
knowing enough about it.
 Be sure you have sufficient knowl-
edge, experience, the proper
replacement parts and tools before
you attempt any vehicle mainte-
nance task.
 Be sure to use the proper nuts,
bolts and other fasteners.
“English” and “metric” fasteners
can be easily confused. If you use
the wrong fasteners, parts can later
break or fall off. You could be hurt.

If you are in an area of extreme cold,
where the temperature falls below –22°F
(–30°C), it is recommended that you use
either an SAE 5W-30 synthetic oil or an
SAE 0W-30 oil. Both will provide easier
cold starting and better protection for your
engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. The recom-
mended oils with the starburst symbol are
all you will need for good performance and
engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
 Most trips are less than 5 miles (8 km).
This is particularly important when out-
side temperatures are below freezing.
 Most trips include extensive idling (such
as frequent driving in stop-and-go traf-
fic).
 The vehicle is used for delivery service,
police, taxi or other commercial applica-
tion.Driving under these conditions causes
engine oil to break down sooner. If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,750 miles (6,000 km) or 3 months –
whichever occurs first.
If none of them is true, use the long trip/
highway maintenance schedule. Change
the oil and filter every 7,500 miles (12,000
km) or 6 months – whichever occurs first.
Driving a vehicle with a fully warmed
engine under highway conditions will
cause engine oil to break down slower.
What to Do with Used Oil
Used engine oil contains certain elements
that may be unhealthy for your skin and
could even cause cancer. Don’t let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly dis-
pose of clothing or rags containing used
engine oil. See the manufacturer’s warn-
ings about the use and disposal of oil prod-
ucts.
Used oil can be a threat to the environ-
ment. If you change your own oil, be sure
to drain all the oil from the filter before dis-
posal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into
sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of your used oil, askyour SUZUKI dealer, a service station or a
local recycling center for help.
Engine Air Cleaner/FilterThe engine air cleaner/filter is located on
the passenger’s side of the engine com-
partment. See “Engine Compartment
Overview” in this section for more informa-
tion on location.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter every 7,500
miles (12,000 km) or 6 months – whichever
occurs first.
Replace every 30,000 miles (48,000 km)
or 24 months – whichever comes first.
If you are driving in dusty/dirty conditions,
inspect the filter every 3,750 miles (6,000
CAUTION
Use only engine oil with the Ameri-
can Petroleum Institute Certified For
Gasoline Engines starburst symbol.
Failure to use the recommended oil
can result in engine damage not cov-
ered by your warranty.

Hydraulic ClutchThere is one reservoir for both the brake
and the hydraulic clutch fluid. See “Brakes”
in this section for more information.
The hydraulic clutch linkage in your vehicle
is self-adjusting. The master cylinder res-
ervoir is filled with hydraulic fluid.
A fluid loss in this system could indicate a
problem. Have the system inspected and
repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to
determine how often you should check the
fluid level and for the proper fluid. See sec-
tion 6.
How to Check and Add Fluid
To check the fluid level, look on the side of
the reservoir. If the fluid level is betweenthe MIN and the MAX marks on the reser-
voir, the fluid level is correct. The reservoir
is located near the back of the engine com-
partment on the driver’s side of the vehicle.
See “Engine Compartment Overview” in
this section for more information on loca-
tion.
Engine CoolantThe following explains your cooling system
and how to add coolant when it is low. If
you have a problem with engine overheat-
ing, see “Engine Overheating” in this sec-
tion.
What to Use
The cooling system in your vehicle is
designed to use either Dex-cool coolant,
which is red in color, or silicate based cool-
ant, which is blue. These two types of cool-
ant are not compatible with each other and
should never be mixed. Therefore, if the
original coolant in your vehicle’s cooling
system was red, then you should use only
Dex-cool coolant for the life of your vehicle.
If the original coolant in your vehicle's cool-
ing system was blue, then you should use
only silicate based coolant for the life of
your vehicle. Even if the cooling system
has been completely drained before a refill,
do not switch types of coolant.Use a 60/40 mixture of clean, drinkable
water and engine coolant which won’t
damage aluminum parts. If another type of
coolant is used, aluminum parts might be
subject to corrosion.
You can also use a recycled coolant with a
complete coolant flush and refill. If you use
this coolant mixture, you don’t need to add
anything else.
A 60/40 mixture of clean, drinkable water
and proper coolant will:
 Give freezing protection down to –33°F
(–36°C).
 Give boiling protection up to 268°F
(131°C).
 Protect against rust and corrosion.
 Help keep the proper engine tempera-
ture.
 Let the warning lights and gauges work
as they should.
For protection in extremely cold weather
conditions, use a 50/50 mixture of clean,
drinkable water and proper coolant.
WARNING
Do not mix Dex-cool and silicate
based coolant in your coolant sys-
tem.
The mixture can damage the cooling
system.

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.

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

 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.

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.
