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.

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.

See “Fog Lamps” under Exterior Lamps in
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.

tire pressure monitoring system is func-
tioning properly.
Your vehicle has also been equipped with
a TPMS malfunction indictor to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.In this situation, please have the system
inspected by an authorized service facility.
If you replace one or more tires and the
TPMS warning light goes off during driv-
ing, there is no problem. However, if the
warning light does not go off, or if it flashes
again when the vehicle is driven, have the
vehicle inspected by an authorized service
facility.
WARNING
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label and
this manual. (If your vehicle has tires
of a different size than the size indi-
cated on the vehicle label or tire infla-
tion pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life and may
affect the vehicle’s handling and
stopping ability.
(Continued)
WARNING
(Continued)
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger illumi-
nation of the TPMS low tire pressure
telltale.
WARNING
If the tire pressure monitoring system
warning light does not illuminate
when the ignition key is turned to the
“ON” position, have the system
inspected by an authorized service
facility. If the warning light flashes
while driving, check to see whether
the warning light goes off after a few
minutes of driving.
WARNING
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunctions
may occur for a variety of reasons,
including the installation of replace-
ment or alternate tires or wheels on
the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

time and energy. See the next part,
“Freeway Driving.”
 Treat a green light as a warning signal. A
traffic light is there because the corner is
busy enough to need it. When a light
turns green, and just before you start to
move, check both ways for vehicles that
have not cleared the intersection or may
be running the red light.Freeway DrivingMile for mile, freeways (also called thru-
ways, parkways, expressways, turnpikes or
superhighways) are the safest of all roads.
But they have their own special rules.
The most important advice on freeway
driving is: Keep up with traffic and keep to
the right. Drive at the same speed most of
the other drivers are driving. Too-fast or
too-slow driving breaks a smooth trafficflow. Treat the left lane on a freeway as a
passing lane.
At the entrance, there is usually a ramp
that leads to the freeway. If you have a
clear view of the freeway as you drive
along the entrance ramp, you should begin
to check traffic. Try to determine where you
expect to blend with the flow. Try to merge
into the gap at close to the prevailing
speed. Switch on your turn signal, check
your mirrors and glance over your shoulder
as often as necessary. Try to blend
smoothly with the traffic flow.
Once you are on the freeway, adjust your
speed to the posted limit or to the prevail-
ing rate if it’s slower. Stay in the right lane
unless you want to pass.
Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance
quickly over your shoulder to make sure
there isn’t another vehicle in your “blind”
spot.
Once you are moving on the freeway,
make certain you allow a reasonable fol-
lowing distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move
to the proper lane well in advance. If you
miss your exit, do not, under any circum-
stances, stop and back up. Drive on to the
next exit.The exit ramp can be curved, sometimes
quite sharply. The exit speed is usually
posted. Reduce your speed according to
your speedometer, not to your sense of
motion. After driving for any distance at
higher speeds, you may tend to think you
are going slower than you actually are.
Before Leaving on a Long TripMake sure you’re ready. Try to be well
rested. If you must start when you’re not
fresh – such as after a day’s work – don’t
plan to make too many miles that first part
of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you
keep it serviced and maintained, it’s ready
to go. If it needs service, have it done
before starting out. Of course, you’ll find
experienced and able service experts in
SUZUKI dealerships all across North
America. They’ll be ready and willing to
help if you need it.
Here are some things you can check
before a trip:
 Windshield Washer Fluid: Is the reser-
voir full? Are all windows clean inside
and outside?
 Wiper Blades: Are they in good shape?
 Fuel, Engine Oil, Other Fluids: Have you
checked all levels?
 Lamps: Are they all working? Are the
lenses clean?

Run your engine only as long as you must.
This saves fuel. When you run the engine,
make it go a little faster than just idle. That
is, push the accelerator slightly. This uses
less fuel for the heat that you get and it
keeps the battery charged. You will need a
well-charged battery to restart the vehicle,
and possibly for signaling later on with your
headlamps. Let the heater run for a while.
Then, shut the engine off and close the
window almost all the way to preserve the
heat. Start the engine again and repeat
this only when you feel really uncomfort-
able from the cold. But do it as little as pos-
sible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the
vehicle and do some fairly vigorous exer-
cises every half hour or so until help
comes.
If You Are Stuck: In Sand, Mud, Ice or
Snow
In order to free your vehicle when it is
stuck, you will need to spin the wheels, but
you don’t want to spin your wheels too fast.
The method known as “rocking” can help
you get out when you’re stuck, but you
must use caution.For information about using tire chains on
your vehicle, see “Tire Chains” in section 5.Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and
right. That will clear the area around your
front wheels. Then shift back and forth
between REVERSE (R) and a forward
gear (or with a manual transmission,
between FIRST (1) or SECOND (2) and
REVERSE (R)), spinning the wheels as lit-
tle as possible. Release the accelerator
pedal while you shift, and press lightly on
the accelerator pedal when the transmis-
sion is in gear. By slowly spinning your
wheels in the forward and reverse direc-
tions, you will cause a rocking motion that
may free your vehicle. If that doesn’t get
you out after a few tries, you may need to
be towed out. If you do need to be towed
out, see “Towing Your Vehicle” in the fol-
lowing section.
WARNING
If you let your tires spin at high
speed, they can explode, and you or
others could be injured. And, the
transmission or other parts of the
vehicle can overheat. That could
cause an engine compartment fire or
other damage. When you’re stuck,
spin the wheels as little as possible.
Don’t spin the wheels above 35 mph
(55 km/h) as shown on the speedom-
eter.
CAUTION
Spinning your wheels can destroy
parts of your vehicle as well as the
tires. If you spin the wheels too fast
while shifting your transmission back
and forth, you can destroy your trans-
mission. See “Rocking Your Vehicle
To Get It Out.”

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.
