Warning Lights, Gauges and
IndicatorsThis section describes the warning lights
and gauges that may be on your vehicle.
The pictures will help you locate them.
Warning lights and gauges can signal that
something is wrong before it becomes seri-
ous enough to cause an expensive repair
or replacement. Paying attention to your
warning lights and gauges could also save
you or others from injury.
Warning lights come on when there may
be or is a problem with one of your vehi-
cle’s functions. As you will see in the
details on the next few pages, some warn-
ing lights come on briefly when you start
the engine just to let you know they’re
working. If you are familiar with this sec-
tion, you should not be alarmed when this
happens.
Gauges can indicate when there may be or
is a problem with one of your vehicle’s
functions. Often gauges and warning lights
work together to let you know when there’s
a problem with your vehicle.
When one of the warning lights comes on
and stays on when you are driving, or
when one of the gauges shows there may
be a problem, check the gauge that tells
you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can
be costly – and even dangerous. So pleaseget to know your warning lights and
gauges. They’re a big help.
Instrument Panel ClusterYour instrument panel cluster is designed
to let you know at a glance how your vehi-
cle is running. You’ll know how fast you’re
going, how much fuel you’re using and
many other things you’ll need to drive
safely and economically.
Your vehicle has this instrument panel
cluster, which includes indicator warning
lights and gauges that are explained on the
following pages.Speedometer and OdometerYour speedometer lets you see your speed
in both miles per hour (mph) and kilome-
ters per hour (km/h).
Your odometer shows how far your vehicle
has been driven, in miles.

Trip OdometerThe trip odometer can record the number
of kilometers or miles traveled for up to two
trips.
The trip odometer button is located in the
lower right area of the speedometer.
There are two independent trip odometers,
which measure the distances your vehicle
has traveled since you last reset this func-
tion.
You can switch the trip odometer display
between Trip A and Trip B by pressing the
trip odometer button.
To reset each trip meter to zero, press and
hold the trip odometer button until it resets.
TachometerThe tachometer shows your engine speed
in revolutions per minute (rpm).
Safety Belt Reminder LightWhen the key is turned to ON, a chime will
come on for several seconds to remind
people to fasten their safety belts, unless
the driver’s safety belt is already buckled.
The safety belt light will also come on and
stay on until the driver’s safety belt is buck-
led.
If the driver’s belt is already buckled, nei-
ther the chime nor the light will come on.Safety Belt Reminder ToneIf your vehicle has this feature, a tone
(instead of a chime) will sound for several
seconds when the ignition is ON to remind
people to fasten their safety belts. The tone
will not sound if the driver’s safety belt is
fastened.
CAUTION
Keep track of your odometer reading
and check the maintenance schedule
regularly for required services.
Increased wear or damage to certain
parts can result from failure to per-
form required services at the proper
mileage intervals.
CAUTION
Do not operate the engine with the
tachometer in the red area, or engine
damage may occur. The damage
would not be covered by your war-
ranty.

Air Bag Readiness LightThere is an air bag readiness light on the
instrument panel. The air bag readiness
system checks the air bag’s electrical sys-
tem for malfunctions. The light tells you if
there is an electrical problem. The system
check includes the air bag sensor, the air
bag modules, the wiring and the crash
sensing and diagnostic module. For more
information on the air bag system, see “Air
Bag Systems” in section 1.
This light will come on when you start your
vehicle, and it will flash for a few seconds.
Then the light should go out. This means
the system is ready.If the air bag readiness light stays on after
you start the vehicle or comes on or
flashes when you are driving, the air bag
system may not work properly. Have your
vehicle serviced right away.
The air bag readiness light should be illu-
minated for a few seconds when you turn
the ignition key to ON. If the light doesn’t
come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System LightThe charging system light will come on
when you turn on the ignition, and the
engine is not running, as a check to show
you it is working.
When the engine is running, the light
should go out.
If it stays on, or comes on while you are
driving, you may have a problem with the
electrical charging system. It could indicate
that you have a loose generator drive belt,
or another electrical problem. Have it
checked right away. Driving while this light
is on could drain your battery.
If you must drive a short distance with the
light on, be certain to turn off all your
accessories, such as the radio and air con-
ditioner.
WARNING
It is absolutely essential that the
driver and passengers wear their
safety belts at all times. Persons who
are not wearing safety belts have a
much greater risk of injury if an acci-
dent occurs. Make a regular habit of
buckling your safety belt before put-
ting the key in the ignition.
S4U3042A
WARNING
If the air bag readiness light stays on
after you start your vehicle, it means
the air bag system may not be work-
ing properly. The air bags in your
vehicle may not inflate in a crash, or
they could even inflate without a
crash. To help avoid injury to yourself
or others, have your vehicle serviced
right away if the air bag readiness
light stays on after you start your
vehicle.

Brake System Warning LightYour vehicle’s hydraulic brake system is
divided into two parts. If one part isn’t
working, the other part can still work and
you will be able to stop the vehicle. For
good braking, though, you need both parts
working well.
If the warning light comes on, there is a
brake problem. Have your brake system
inspected right away.
This light should come on briefly when you
turn the ignition key to ON. If it doesn’t
come on then, have it fixed so it will be
ready to warn you if there’s a problem.
When the ignition is on, the brake system
warning light will also come on when you

on if your parking brake doesn’t release
fully. If the lights stays on after your parking
brake is fully released, it means you have a
brake problem.If the light comes on while you are driving,
pull off the road and stop carefully. You
may notice that the pedal is harder to
push. Or, the pedal may go closer to the
floor. It may take longer to stop. If the light
is still on, have the vehicle towed for ser-
vice. See “Towing Your Vehicle” in section
4.
Anti-Lock Brake System Warning
LightIf your vehicle has an anti-lock brake sys-
tem, the ABS warning light comes on
briefly when you turn the ignition ON. This
indicates that the system is performing a
self-check and the indicator bulb is operat-
ing properly. The light should go out after
several seconds.
Contact your SUZUKI dealer for repairs if
the ABS warning light does any of the fol-
lowing:
 Does not come on when the ignition is
turned ON.
 Does not go out after several seconds.
 Comes on while driving.
If the ABS warning light comes on while
driving, your vehicle may have an ABS
malfunction. Although your vehicle will
operate normally without ABS, have your
SUZUKI dealer check the system and
make any necessary repairs as soon as
possible.
WARNING
If any of the following conditions
occur, you should immediately ask
your SUZUKI dealer to inspect the
brake system.
 If the brake system warning light

If the warning light stays on, or comes on
while you are driving, the SSPS system
may not be working. If this happens, see
your SUZUKI dealer for service.
Hold Mode LightIf your vehicle has this feature, this light will
come on when the Hold mode is active.
If the HOLD mode light flashes, have your
vehicle checked.
See “Hold Mode” under “Automatic Trans-
mission Operation” in section 2 for addi-
tional information on this feature.Engine Coolant Temperature GaugeYour vehicle is equipped with an engine
coolant temperature gauge. With the igni-tion in the ON position, this gauge shows
the engine coolant temperature.
If the gauge pointer moves into the red
area, your engine is too hot! It means that
your engine coolant has overheated.
If you have been operating your vehicle
under normal driving conditions, you
should pull off the road, stop your vehicle
and turn off the engine as soon as possi-
ble.
See “Engine Overheating” in section 5.
Malfunction Indicator LampCheck Engine Light
Your vehicle is equipped with a computer
which monitors operation of the fuel, igni-
tion and emission control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is
intended to assure that emissions are at
acceptable levels for the life of the vehicle,
helping to produce a cleaner environment.
The Check Engine Light comes on to indi-
cate that there is a problem and service is
required. Malfunctions often will be indi-

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:

3-24 INSTRUMENT PANEL
85Z03-03E
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.
