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.

this section for more information.Cruise Control LightIf your vehicle has this feature, this light will
come on briefly when the ignition is turned
on.
The CRUISE light comes on whenever the
cruise control is set. See “Cruise Control”
in this section. The light will turn off when
the cruise control is turned off.High beam On LightThis light comes on whenever the high-
beam headlamps are on.
See “Headlamp High/Low-Beam Changer”
under “Turn Signal/Multifunction Lever” in
this section for additional information.
Fuel GaugeYour fuel gauge tells you approximately
how much fuel you have left, when the igni-
tion is on. When the indicator nears empty,
the low fuel warning light will come on. You
still have a little fuel left, but you should get
more soon. See “Low Fuel Warning Light”
in this section for more information.
Here are four things that some owners ask
about. None of these show a problem with
your fuel gauge:
 At the service station, the gas pump
shuts off before the gauge reads full.
 It takes a little more or less fuel to fill up
than the gauge indicated. For example,
the gauge may have indicated the tank
was half full, but it actually took a little
more or less than half the tank’s capacity
to fill the tank. The indicator moves a little when you
turn a corner or speed up.
 The gauge goes back to empty when
you turn off the ignition.
For your fuel tank capacity, see “Capacities
and Specifications” in section 5.
Low Fuel Warning LightThis light will come on when the fuel tank is
low on fuel.
To turn it off, add fuel to the fuel tank. See
“Filling Your Tank” in section 5.

Determining Compatibility of Tire and
Vehicle Load Limits
The 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 onthe 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 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.
Towing a TrailerDo not use your vehicle to tow a trailer. The
vehicle is not designed or intended for
such use. Towing a trailer can adversely
affect handling, durability and fuel econ-
omy.
WARNING
Things you put inside your vehicle
can strike and injure people in a sud-
den stop or turn, or in a crash.
 Put things in the trunk or rear area
of your vehicle. In a trunk, put them
as far forward as you can. Try to
spread the weight evenly. If you
have fold-down rear seats, you’ll
find four anchors on the back wall
of your trunk. You can use these
anchors to tie down lighter loads.
They’re not strong enough for
heavy things, however, so put them
as far forward as you can in the
trunk or rear area.
 Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
 Don’t leave an unsecured child
restraint in your vehicle.
 When you carry something inside
the vehicle, secure it whenever you
can.
 Don’t leave a seat folded down
unless you need to.

To open the fuel filler door, pull up on the
fuel filler door release lever located on the
floor to the left of the driver’s seat.
The fuel cap is located on the passenger’s
side of your vehicle.While refueling, hang the tethered cap
inside the fuel door.
To remove the fuel cap, turn it slowly to the
left (counterclockwise).
Be careful not to spill fuel. Don’t top off or
overfill your tank, and wait a few seconds
after you’ve finished pumping before you
remove the nozzle. Clean fuel from painted
surfaces as soon as possible. See “Clean-
ing the Outside of Your Vehicle” in this sec-
tion.
When you put the fuel cap back on, turn it
to the right (clockwise) until you hear a
clicking sound. Make sure you fully install
the cap. The diagnostic system can deter-
mine if the fuel cap has been left off or is
improperly installed. This would allow fuel
to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in section 3.
N4U5041A
WARNING
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. This spray
can happen if your tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and wait for
any “hiss” noise to stop. Then
unscrew the cap all the way.
WARNING
If a fire starts while you’re refueling,
don’t remove the nozzle. Shut off the
flow of fuel by shutting off the pump
or by notifying the station attendant.
Leave the area immediately.
CAUTION
If you need a new fuel cap, be sure to
get a genuine SUZUKI cap or its
equivalent. Your SUZUKI dealer can
get one for you. If you get the
improper type, it may not fit properly.
This may cause your malfunction
indicator lamp to light and may dam-
age your fuel tank and emissions
system. See “Malfunction Indicator
Lamp” in the Index.

Engine OilIf the oil pressure light appears on the
instrument cluster, it means you need to
check your engine oil level right away.
For more information, see “Oil Pressure
Light” in section 3.
You should check your engine oil level reg-
ularly; this is an added reminder.
Checking Engine Oil
It’s a good idea to check your engine oil
every time you get fuel. In order to get an
accurate reading, the oil must be warm
and the vehicle must be on level ground.Use the engine oil dipstick to check the oil
level. The dipstick’s handle will be a yellow
ring. See “Engine Compartment Overview”
in this section for the location of the engine
oil dipstick.
Turn off the engine and give the oil several
minutes to drain back into the oil pan. If
you don’t, the oil dipstick might not show
the actual level.
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back in all
the way. Remove it again, keeping the tip
down and check the level.
When to Add Engine OilIf the oil is at or below the MIN mark, then
you’ll need to add at least one quart of oil.
But you must use the right kind. This sec-
tion explains what kind of oil to use. For
engine oil crankcase capacity, see “Capac-
ities and Specifications” in this section.
CAUTION
Don’t add too much oil. If your engine
has so much oil that the oil level gets
above the upper mark that shows the
proper operating range, your engine
could be damaged.

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.
