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.

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?

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.

km) or 3 months. If necessary, clean or
replace it.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter, remove the
filter from the vehicle and lightly shake the
filter to release loose dust and dirt. If the fil-
ter remains “caked” with dirt, a new filter is
required.
To inspect or replace the filter, do the fol-
lowing:
1) Remove the four screws on the cover.
2) Lift off the cover.
3) Check or replace the engine air
cleaner/filter. See “Normal Mainte-
nance Replacement Parts” in this sec-
tion for replacement part numbers.
4) Reinstall the filter, put the cover back on
tightly, and tighten the screws.
Automatic Transmission FluidTo ensure proper functioning, efficiency,
and durability of the automatic transmis-
sion, be sure to keep the transmission fluid
at the proper level. Too much or too little
fluid can cause problems.
The fluid level must be checked with the
engine running and the selector lever in P
(Park). The vehicle must be up to normal
operating temperature and parked on level
ground.
The normal operating temperature for the
fluid will be reached after driving about 10
minutes.
Checking Automatic Transmission Fluid
Level
If the fluid is contaminated or discolored,
change the automatic transmission fluid.
A decrease in the fluid level indicates a
leak in the automatic transmission. If
noted, contact your SUZUKI dealer for
repair as soon as possible.1) Start the engine.
2) Warm up the engine until the tempera-
ture of the automatic transmission fluid
reaches approximately 40°C (104°F).
3) Move the selector lever from “P” to “1”
and return to “P”. Wait for a few sec-
onds at each select position until the
selected gears are fully engaged.
WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air cleaner
not only cleans the air, it helps to
stop flame if the engine backfires. If it
isn’t there and the engine backfires,
you could be burned. Don’t drive with
it off, and be careful working on the
engine with the air cleaner/filter off.
CAUTION
If the air cleaner/filter is off, a backfire
can cause a damaging engine fire.
And, dirt can easily get into your
engine, which will damage it. Always
have the air cleaner/filter in place
when you’re driving.
WARNING
This work requires special skill and
equipment. Before attempting to do
the work, be sure you are fully
acquainted with doing this job.
Have your SUZUKI dealer do this
work if you are not confident you can
complete the task safely.
Otherwise, you could be injured or
could damage the vehicle.

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.

When your brake fluid falls to a low level,
your brake warning light will come on. See
“Brake System Warning Light” in section 3.
What to Add
When you do need brake fluid, use only
DOT-3 brake fluid. Use new brake fluid
from a sealed container only. See “Recom-
mended Fluids and Lubricants” in section
6.
Always clean the brake fluid reservoir cap
and the area around the cap before remov-
ing it. This will help keep dirt from entering
the reservoir.Brake Wear
Your vehicle has front and rear disc brakes.
Disc brake pads have built-in wear indica-
tors that make a high-pitched warning
sound when the brake pads are worn and
new pads are needed. The sound may
come and go or be heard all the time your
vehicle is moving (except when you are
pushing on the brake pedal firmly).Some driving conditions or climates may
cause a brake squeal when the brakes are
first applied or lightly applied. This does
not mean something is wrong with your
brakes.
Properly torqued wheel nuts are necessary
to help prevent brake pulsation. When tires
are rotated, inspect brake pads for wear
and evenly tighten wheel nuts in the proper
sequence to SUZUKI torque specifica-
tions.
Brake linings should always be replaced as
complete axle sets.
See “Brake System Inspection” in section
6.
WARNING
If you have too much brake fluid, it
can spill on the engine. The fluid will
burn if the engine is hot enough. You
or others could be burned, and your
vehicle could be damaged.
WARNING
With the wrong kind of fluid in your
brake system, your brakes may not
work well, or they may not even work
at all. This could cause a crash.
Always use the proper brake fluid.
CAUTION
 Using the wrong fluid can badly
damage brake system parts. For
example, just a few drops of min-
eral-based oil, such as engine oil,
in your brake system can damage
brake system parts so badly that
they’ll have to be replaced. Don’t let
someone put in the wrong kind of
fluid.
 If you spill brake fluid on your vehi-
cle’s painted surfaces, the paint fin-
ish can be damaged. Be careful not
to spill brake fluid on your vehicle.
If you do, wash it off immediately.
See “Appearance Care” in the
Index.
WARNING
The brake wear warning sound
means that soon your brakes won’t
work well. That could lead to an acci-
dent. When you hear the brake wear
warning sound, have your vehicle
serviced.
CAUTION
Continuing to drive with worn-out
brake pads could result in costly
brake repair.

2) Get the vehicles close enough so the
jumper cables can reach, but be sure
the vehicles aren’t touching each other.
If they are, it could cause a ground con-
nection you don’t want. You wouldn’t be
able to start your vehicle, and the bad
grounding could damage the electrical
systems.
To avoid the possibility of the vehicles
rolling, set the parking brake firmly on
both vehicles involved in the jump start
procedure. Put an automatic transmis-
sion in PARK (P) or a manual transmis-
sion in NEUTRAL before setting the
parking brake.3) Turn off the ignition on both vehicles.
Unplug unnecessary accessories
plugged into the cigarette lighter or in
the accessory power outlet. Turn off the
radio and all lamps that aren’t needed.
This will avoid sparks and help save
both batteries. And it could save your
radio!
4) Open the hoods and locate the batter-
ies. Find the positive (+) and negative
(–) terminal locations on each vehicle.
Your vehicle’s positive (+) terminal is
located under a red tethered cap on the
battery. The negative (–) terminal is
located under a black tethered cap on
the battery. See “Engine Compartment
Overview” in this section for more infor-
mation on location. Flip the caps up to
access the positive (+) and negative (–)
terminals.
5) Check that the jumper cables don’t
have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged, too.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) or to a
remote positive (+) terminal if the vehi-
cle has one. Negative (–) will go to a
heavy, unpainted metal engine part or
to a remote negative (–) terminal if the
vehicle with the dead battery has one.
Don’t connect positive (+) to negative
(–) or you’ll get a short that would dam-
CAUTION
If the other system isn’t a 12-volt sys-
tem with a negative ground, both
vehicles can be damaged. Only use
vehicles with 12-volt systems with
negative grounds to jump start your
vehicle.
CAUTION
If you leave your radio or other acces-
sories on during the jump starting
procedure, they could be damaged.
The repairs wouldn’t be covered by
your warranty. Always turn off your
radio and other accessories when
jump starting your vehicle.
WARNING
An electric fan under the hood can
start up and injure you even when the
engine is not running. Keep hands,
clothing and tools away from any
underhood electric fan.
WARNING
Using a match near a battery can
cause battery gas to explode. People
have been hurt doing this, and some
have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough
water. You don’t need to add water to
the battery installed in your new vehi-
cle. But if a battery has filler caps, be
sure the right amount of fluid is
there. If it is low, add water to take
care of that first. If you don’t, explo-
sive gas could be present.
Battery fluid contains acid that can
burn you. Don’t get it on you. If you
accidentally get it in your eyes or on
your skin, flush the place with water
and get medical help immediately.
