cle’s stability when you make a hard stop
on a slippery road.) Whether you have an
anti-lock braking system or not, you’ll want
to begin stopping sooner than you would
on dry pavement. Without anti-lock brakes,
if you feel your vehicle begin to slide, let up
on the brakes a little. Push the brake pedal
down steadily to get the most traction you
can.
Remember, unless you have anti-lock, if
you brake so hard that your wheels stop
rolling, you’ll just slide. Brake so your
wheels always keep rolling and you can
still steer.
 Whatever your braking system, allow
greater following distance on any slip-
pery road.
 Watch for slippery spots. The road might
be fine until you hit a spot that’s covered
with ice. On an otherwise clear road, ice
patches may appear in shaded areas
where the sun can’t reach: around
clumps of trees, behind buildings or
under bridges. Sometimes the surface of
a curve or an overpass may remain icy
when the surrounding roads are clear. If
you see a patch of ice ahead of you,
brake before you are on it. Try not to
brake while you’re actually on the ice,
and avoid sudden steering maneuvers.If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation. You should
probably stay with your vehicle unless you
know for sure that you are near help and
you can hike through the snow. Here are
some things to do to summon help and
keep yourself and your passengers safe:
 Turn on your hazard flashers.
 Tie a red cloth to your vehicle to alert
police that you’ve been stopped by the
snow.
 Put on extra clothing or wrap a blanket
around you. If you have no blankets or
extra clothing, make body insulators
from newspapers, burlap bags, rags,
floor mats – anything you can wrap
around yourself or tuck under your cloth-
ing to keep warm.You can run the engine to keep warm, but
be careful.
WARNING
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get
inside. CO could overcome you and
kill you. You can’t see it or smell it, so
you might not know it is in your vehi-
cle. Clear away snow from around the
base of your vehicle, especially any
that is blocking your exhaust pipe.
And check around again from time to
time to be sure snow doesn’t collect
there.
Open a window just a little on the
side of the vehicle that’s away from
the wind. This will help keep CO out.

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.

Windshield Washer FluidThe windshield washer fluid reservoir is
located in the front of the engine compart-
ment on the driver’s side. See “Engine
Compartment Overview” in this section for
more information on location.
What to Use
When you need windshield washer fluid,
be sure to read the manufacturer’s instruc-
tions before use. If you will be operating
your vehicle in an area where the tempera-
ture may fall below freezing, use a fluid
that has sufficient protection against freez-
ing.Adding Washer Fluid
Open the cap with the washer symbol on it.
Add washer fluid until the tank is full.
BrakesBrake Fluid
Your brake master cylinder reservoir is
located near the back of the engine com-
partment on the driver’s side of the vehicle.
It is filled with DOT-3 brake fluid. See
“Engine Compartment Overview” in this
section for the location of the reservoir.
There are only two reasons why the brake
fluid level in the reservoir might go down.
The first is that the brake fluid goes down
to an acceptable level during normal brake
lining wear.
When new linings are put in, the fluid level
goes back up. The other reason is that fluid
is leaking out of the brake system. If it is,
you should have your brake system fixed,
since a leak means that sooner or later
your brakes won’t work well, or won’t work
at all.
So, it isn’t a good idea to “top off ” your
brake fluid. Adding brake fluid won’t correct
a leak. If you add fluid when your linings
are worn, then you’ll have too much fluid
when you get new brake linings. You
should add (or remove) brake fluid, as nec-
essary, only when work is done on the
brake hydraulic system.
CAUTION
 When using concentrated washer
fluid, follow the manufacturer’s
instructions for adding water.
 Don’t mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage your
washer fluid tank and other parts of
the washer system. Also, water
doesn’t clean as well as washer
fluid.
 Fill your washer fluid tank only
three-quarters full when it’s very
cold. This allows for expansion if
freezing occurs, which could dam-
age the tank if it is completely full.
 Don’t use engine coolant (anti-
freeze) in your windshield washer.
It can damage your washer system
and paint.

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.

Brake Pedal Travel
See your SUZUKI dealer if the brake pedal
does not return to normal height, or if there
is a rapid increase in pedal travel. This
could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake
stop, your disc brakes adjust for wear. If
you rarely make a moderate or heavier
stop, then your brakes might not adjust
correctly. If you drive in that way, then –
very carefully – make a few moderate
brake stops about every 1,000 miles
(1,600 km), so your brakes will adjust prop-
erly.
Replacing Brake System Parts
The braking system on a vehicle is com-
plex. Its many parts have to be of top qual-
ity and work well together if the vehicle is
to have really good braking. When you
replace parts of your braking system – for
example, when your brake linings wear
down and you need new ones put in – be
sure you get new approved SUZUKI
replacement parts. If you don’t, your
brakes may no longer work properly. For
example, if someone puts in brake linings
that are wrong for your vehicle, the balance
between your front and rear brakes can
change – for the worse. The braking per-
formance you’ve come to expect can
change in many other ways if someone
puts in the wrong replacement brake parts.
BatteryYour new vehicle comes with a mainte-
nance free battery. When it’s time for a new
battery, get one that has the replacement
number shown on the original battery’s
label. See “Engine Compartment Over-
view” in this section for battery location.
Vehicle Stor ag e
If you’re not going to drive your vehicle for
25 days or more, remove the black, nega-
tive (–) cable from the battery. This will
help keep your battery from running down.
Contact your SUZUKI dealer to learn how
to prepare your vehicle for longer storage
periods.
Jump StartingIf your battery has run down, you may want
to use another vehicle and some jumper
cables to start your vehicle. Be sure to fol-
low the steps below to do it safely.
1) Check the other vehicle. It must have a
12-volt battery with a negative ground
system.
WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the
State of California to cause cancer
and reproductive harm. Wash hands
after handling.
WARNING
Batteries have acid that can burn you
and gas that can explode. You can be
badly hurt if you aren’t careful. See
the next section, “Jump Starting”, for
tips on working around a battery
without getting hurt.
WARNING
Batteries can hurt you. They can be
dangerous because:
 They contain acid that can burn
you.
 They contain gas that can explode
or ignite.
 They contain enough electricity to
burn you.
If you don’t follow these steps
exactly, some or all of these things
can hurt you.
CAUTION
Ignoring the following steps could
result in costly damage to your vehi-
cle that wouldn’t be covered by your
warranty.
Trying to start your vehicle by push-
ing or pulling it won’t work, and it
could damage your vehicle.

7-3GENERAL INFORMATION
85Z04-03E
On-Board Vehicle Computers
and Event Data RecordersYour vehicle is equipped with on-board
computer systems which monitor and
control several aspects of vehicle per-
formance, including the following:
 Emission-related components and
engine parameters such as engine
speed and throttle position are moni-
tored to provide emissions control
and to provide optimum fuel econ-
omy. Your vehicle also has an on-
board diagnostic system which mon-
itors and records information about
emission-related malfunctions.
 Signals from various sensors are
monitored to provide air bag deploy-
ment.
 If your vehicle is equipped with
antilock brakes, conditions such as
vehicle speed and brake perfor-
mance are monitored, so that the
ABS system can provide effective
antilock braking. If your vehicle has
an Electronic Stability Program
(ESP
®) system, conditions such as
yaw rate, lateral acceleration, and
brake fluid pressure are monitored,
so that the ESP
® system can help
the driver control the vehicle in diffi-
cult driving situations.
Some information may be stored by
the on-board computers during normaloperation of the vehicle. This stored
information can assist technicians in
repairing the vehicle when malfunc-
tions occur. Other information is stored
only in the event of crash, by computer
systems that are commonly called
Event Data Recorders (EDRs).
In a crash event, EDRs such as the
Airbag Sensing and Diagnostic Mod-
ule (SDM) in your vehicle may record
information about the condition of the
vehicle and how it was operated, such
as data related to airbag readiness,
airbag performance, safety belt usage,
and the severity of the collision. These
data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur and lead to
the designing of safer vehicles. The
SDM in your vehicle does not collect
or store personal information.
To read the stored information, special
equipment is needed and access to
the vehicle or storage device is
required. SUZUKI will not access infor-
mation about a crash event or share it
with others other than with the consent
of the vehicle owner or lessee, in
response to an official request from
the police or similar government office,
as part of SUZUKI’s defense of litiga-
tion through the discovery process, or
as required by law.In addition, once SUZUKI collects or
receives data, SUZUKI may use the
data for research conducted by
SUZUKI, make the data available for
outside research if need is shown and
confidentiality is assured, or make
summary data which does not identify
specific vehicles available for outside
research.
Others, such as law enforcement per-
sonnel, may have access to the spe-
cial equipment that can read the
information if they have access to the
vehicle or storage device.
