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.

4-3 DRIVING YOUR VEHICLE
85Z03-03E
Sometimes, as when you’re driving on
snow or ice, it’s easy to ask more of those
control systems than the tires and road
can provide. That means you can lose con-
trol of your vehicle.BrakingBraking action involves perception time
and reaction time.
First, you have to decide to push on the
brake pedal. That’s perception time. Then
you have to bring up your foot and do it.
That’s reaction time.
Average reaction time is about 3/4 of a
second. But that’s only an average. It might
be less with one driver and as long as two
or three seconds or more with another.
Age, physical condition, alertness, coordi-
nation and eyesight all play a part. So do
alcohol, drugs and frustration. But even in3/4 of a second, a vehicle moving at 60
mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emer-
gency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances
vary greatly with the surface of the road
(whether it’s pavement or gravel) the condi-
tion of the road (wet, dry, icy) tire tread the
condition of your brakes the weight of the
vehicle and the amount of brake force
applied.
Avoid needless heavy braking. Some peo-
ple drive in spurts – heavy acceleration fol-
lowed by heavy braking – rather than
keeping pace with traffic. This is a mistake.
Your brakes may not have time to cool
between hard stops. Your brakes will wear
out much faster if you do a lot of heavy
braking. If you keep pace with the traffic
and allow realistic following distances, you
will eliminate a lot of unnecessary braking.
That means better braking and longer
brake life.
If your engine ever stops while you’re driv-
ing, brake normally but don’t pump your
brakes. If you do, the pedal may get harder
to push down. If your engine stops, you will
still have some power brake assist. But you
will use it when you brake. Once the power
assist is used up, it may take longer to stop
and the brake pedal will be harder to push.
Anti-Lock Brake System (ABS)
(if equipped)ABS is an advanced electronic braking
system that will help prevent a braking
skid.
When you start your engine and begin to
drive away, your anti-lock brake system will
check itself. You may hear a momentary
motor or clicking noise while this test is
going on, and you may even notice that
your brake pedal moves a little. This is nor-
mal.
If there’s a problem with the anti-lock brake
system, this warning light will stay on. See
“Anti-Lock Brake System Warning Light” in
section 3.

SteeringPower Steering
If you lose power steering assist because
the engine stops or the system is not func-
tioning, you can steer but it will take much
more effort.
Speed Sensitive Power Steering
System
This system continuously adjusts the effort
you feel when steering at all vehicle
speeds. It provides ease when parking, yet
a firm, solid feel at highway speeds.
If your vehicle has this system, it varies the
amount of effort required to steer the vehi-
cle in relation to the speed of the vehicle.
The amount of steering effort required is
less at slower speeds to make the vehicle
more maneuverable and easier to park. At
faster speeds, the steering effort increases
to provide a sport-like feel to the steering.
This provides maximum control and stabil-
ity.
This warning light will stay on, or come on
while you are driving, if there’s a problem
with the SSPS system.When this warning light is on, your vehicle
will seem harder to steer than normal
when parking or driving slowly. You will still
have power steering, but steering will be
stiffer than normal at slow speeds. See
your SUZUKI dealer for service.
Steering Tips
Driving on Curves
It’s important to take curves at a reason-
able speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here’s why:
Experienced driver or beginner, each of us
is subject to the same laws of physics
when driving on curves. The traction of the
tires against the road surface makes it pos-
sible for the vehicle to change its path
when you turn the front wheels. If there’s
no traction, inertia will keep the vehicle
going in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll
understand this.
The traction you can get in a curve
depends on the condition of your tires and
the road surface, the angle at which the
curve is banked, and your speed. While
you’re in a curve, speed is the one factor
you can control.
Suppose you’re steering through a sharp
curve. Then you suddenly apply the
brakes. Both control systems – steeringand braking – have to do their work where
the tires meet the road. Unless you have
four-wheel anti-lock brakes, adding the
hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you’re steer-
ing through a sharp curve and you sud-
denly accelerate. Those two control
systems – steering and acceleration – can
overwhelm those places where the tires
meet the road and make you lose control.
What should you do if this ever happens?
Ease up on the brake or accelerator pedal,
steer the vehicle the way you want it to go,
and slow down.
Speed limit signs near curves warn that
you should adjust your speed. Of course,
the posted speeds are based on good
weather and road conditions. Under less
favorable conditions you’ll want to go
slower.
If you need to reduce your speed as you
approach a curve, do it before you enter
the curve, while your front wheels are
straight ahead.
Try to adjust your speed so you can “drive”
through the curve. Maintain a reasonable,
steady speed. Wait to accelerate until you
are out of the curve, and then accelerate
gently into the straightaway.

steer the way you want the vehicle to go. If
you start steering quickly enough, your
vehicle may straighten out. Always be
ready for a second skid if it occurs.
Of course, traction is reduced when water,
snow, ice, gravel or other material is on the
road. For safety, you’ll want to slow down
and adjust your driving to these conditions.
It is important to slow down on slippery
surfaces because stopping distance will be
longer and vehicle control more limited.
While driving on a surface with reduced
traction, try your best to avoid sudden
steering, acceleration or braking (including
engine braking by shifting to a lower gear).
Any sudden changes could cause the tires
to slide. You may not realize the surface is
slippery until your vehicle is skidding.
Learn to recognize warning clues – such
as enough water, ice or packed snow on
the road to make a “mirrored surface” –
and slow down when you have any doubt.
If you have the anti-lock braking system,
remember: It helps avoid only the braking
skid. If you do not have anti-lock, then in a
braking skid (where the wheels are no
longer rolling), release enough pressure
on the brakes to get the wheels rolling
again. This restores steering control. Push
the brake pedal down steadily when you
have to stop suddenly. As long as the
wheels are rolling, you will have steering
control.
Driving at NightNight driving is more dangerous than day
driving. One reason is that some drivers
are likely to be impaired – by alcohol or
drugs, with night vision problems, or by
fatigue.
Here are some tips on night driving.
 Drive defensively.
 Don’t drink and drive.
 Adjust your inside rearview mirror to
reduce the glare from headlamps behind
you.
 Since you can’t see as well, you may
need to slow down and keep more space
between you and other vehicles.
 Slow down, especially on higher speed
roads. Your headlamps can light up only
so much road ahead.
 In remote areas, watch for animals. If you’re tired, pull off the road in a safe
place and rest.
No one can see as well at night as in the
daytime. But as we get older these differ-
ences increase. A 50-year-old driver may
require at least twice as much light to see
the same thing at night as a 20-year-old.
What you do in the daytime can also affect
your night vision. For example, if you
spend the day in bright sunshine you are
wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if
you’re driving, don’t wear sunglasses at
night. They may cut down on glare from
headlamps, but they also make a lot of
things invisible.
You can be temporarily blinded by
approaching headlamps. It can take a sec-
ond or two, or even several seconds, for
your eyes to readjust to the dark. When
you are faced with severe glare (as from a
driver who doesn’t lower the high beams,
or a vehicle with misaimed headlamps),
slow down a little. Avoid staring directly
into the approaching headlamps.
Keep your windshield and all the glass on
your vehicle clean – inside and out. Glare
at night is made much worse by dirt on the
glass. Even the inside of the glass can
build up a film caused by dust. Dirty glass
makes lights dazzle and flash more than
clean glass would, making the pupils of
your eyes contract repeatedly.

Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride on the water. This
can happen if the road is wet enough and
you’re going fast enough. When your vehi-
cle is hydroplaning, it has little or no con-
tact with the road.
Hydroplaning doesn’t happen often. But it
can if your tires do not have much tread or
if the pressure in one or more is low. It can
happen if a lot of water is standing on the
road. If you can see reflections from trees,
telephone poles or other vehicles, and
raindrops “dimple” the water’s surface,
there could be the possibility of hydroplan-
ing.
Hydroplaning usually happens at higher
speeds. There just isn’t a hard and fast rule
about hydroplaning. The best advice is to
slow down when it is raining.Driving Through Deep Standing Water
Driving Trough Flowing Water
Some Other Rainy Weather Tips
 Besides slowing down, allow some extra
following distance. And be especially
careful when you pass another vehicle.Allow yourself more clear room ahead,
and be prepared to have your view
restricted by road spray.
 Have good tires with proper tread depth.
See “Tires” in section 5.
City DrivingOne of the biggest problems with city
streets is the amount of traffic on them.
You’ll want to watch out for what the other
drivers are doing and pay attention to traf-
fic signals.
Here are ways to increase your safety in
city driving:
 Know the best way to get to where you
are going. Get a city map and plan your
trip into an unknown part of the city just
as you would for a cross-country trip.
 Try to use the freeways that rim and
crisscross most large cities. You’ll save
CAUTION
If you drive too quickly through deep
puddles or standing water, water can
come in through your engine’s air
intake and badly damage your
engine. Never drive through water
that is slightly lower than the under-
body of your vehicle. If you can’t
avoid deep puddles or standing
water, drive through them very
slowly.
WARNING
Flowing or rushing water creates
strong forces. If you try to drive
through flowing water, as you might
at a low water crossing, your vehicle
can be carried away. As little as six
inches of flowing water can carry
away a smaller vehicle. If this hap-
pens, you and other vehicle occu-
pants could drown. Don’t ignore
police warning signs, and otherwise
be very cautious about trying to drive
through flowing water.

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?
Your Driving, the Road, and Your Vehicle:

4-12 DRIVING YOUR VEHICLE
85Z03-03E
 Tires: They are vitally important to a
safe, trouble-free trip. Is the tread good
enough for long-distance driving? Are
the tires all inflated to the recommended
pressure?
 Weather Forecasts: What’s the weather
outlook along your route? Should you
delay your trip a short time to avoid a
major storm system?
 Maps: Do you have up-to-date maps?Highway HypnosisIs there actually such a condition as “high-
way hypnosis”? Or is it just plain falling
asleep at the wheel? Call it highway hyp-
nosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires on the road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you
sleepy. Don’t let it happen to you! If it does,
your vehicle can leave the road in less than
a second, and you could crash and be
injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
 Make sure your vehicle is well ventilated,
with a comfortably cool interior.
 Keep your eyes moving. Scan the road
ahead and to the sides. Check your rear-
view mirrors and your instruments fre-
quently. If you get sleepy, pull off the road into a
rest, service or parking area and take a
nap, get some exercise, or both. For
safety, treat drowsiness on the highway
as an emergency.
Hill and Mountain RoadsDriving on steep hills or mountains is differ-
ent from driving in flat or rolling terrain.
If you drive regularly in steep country, or if
you’re planning to visit there, here are
some tips that can make your trips safer
and more enjoyable.
 Keep your vehicle in good shape. Check
all fluid levels and also the brakes, tires,
cooling system and transmission. These
parts can work hard on mountain roads.
 Know how to go down hills. The most
important thing to know is this: let your
engine do some of the slowing down.Shift to a lower gear when you go down
a steep or long hill.
 Know how to go uphill. You may want to
shift down to a lower gear. The lower
gears help cool your engine and trans-
mission, and you can climb the hill bet-
ter.
 Stay in your own lane when driving on
two-lane roads in hills or mountains.
Don’t swing wide or cut across the cen-
ter of the road. Drive at speeds that let
you stay in your own lane.
WARNING
If you don’t shift down, your brakes
could get so hot that they wouldn’t
work well. You would then have poor
braking or even none going down a
hill. You could crash. Shift down to let
your engine assist your brakes on a
steep downhill slope.
WARNING
Coasting downhill in NEUTRAL (N) or
with the ignition off is dangerous.
Your brakes will have to do all the
work of slowing you down. They
could get so hot that they wouldn’t
work well. You would then have poor
braking or even none going down a
hill. You could crash. Always have
your engine running and your vehicle
in gear when you go downhill.
