What to Add
When you do need brake uid, use only DOT-3
brake uid. Use new brake uid from a sealed
container only. SeeRecommended Fluids
and Lubricants on page 345.
Always clean the brake uid reservoir cap and
the area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the
brake/clutch system, the brakes/clutch
may not work well, or they may not even
work at all. This could cause a crash.
Always use the proper brake uid.Notice:
Using the wrong uid can badly damage
brake/clutch system parts. For example,
just a few drops of mineral-based oil,
such as engine oil, in the brake/clutch
hydraulic system can damage brake/clutch
system parts so badly that they will
have to be replaced. Do not let someone
put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 318.

Brake Wear
Your vehicle has four-wheel disc brakes.
Front disc brake pads have built-in wear indicators
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 rmly.
{CAUTION:
The brake wear warning sound means
that soon the brakes will not work well.
That could lead to an accident. When
you hear the brake wear warning sound,
have your vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates may cause a
brake squeal when the brakes are rst 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 Saturn
torque speci cations.
Brake linings should always be replaced as
complete axle sets.
Brake Pedal Travel
See your retailer 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 apply the brakes, with or without
the vehicle moving, your brakes adjust for wear.

Replacing Brake System Parts
The braking system on a vehicle is complex.
Its many parts have to be of top quality and work
well together if the vehicle is to have really good
braking. Your vehicle was designed and tested
with top-quality Saturn brake parts. 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 Saturn replacement parts.
If you do not, 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
performance you have come to expect can
change in many other ways if someone puts in
the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 242for battery location.
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.

Notice:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
Notice:If the other vehicle’s system is not
a 12-volt system with a negative ground, both
vehicles can be damaged. Only use vehicles
with 12-volt systems with negative grounds to
jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not
want. You would not 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 rmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The
repairs would not be covered by your
warranty. Always turn off your radio and
other accessories when jump starting
your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged
into the cigarette lighter or the accessory
power outlet. Turn off the radio and all lamps
that are not needed. This will avoid sparks
and help save both batteries. And it could
save the radio!

Tire Terminology and De nitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission/
transaxle, power steering, power brakes, power
windows, power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the
plies are laid at alternate angles less than
90 degrees to the centerline of the tread.Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square
inch (psi) or kilopascals (kPa) before a tire has
built up heat from driving. SeeIn ation - Tire
Pressure on page 292.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identi cation Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.

When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut, or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Buying New Tires
Saturn has developed and matched speci c tires
for your vehicle. The original equipment tires
installed on your vehicle, when it was new,
were designed to meet General Motors Tire
Performance Criteria Speci cation (TPC spec)
system rating. If you need replacement tires,
Saturn strongly recommends that you get tires
with the same TPC spec rating. This way, your
vehicle will continue to have tires that are designed
to give the same performance and vehicle safety,
during normal use, as the original tires.
GM’s exclusive TPC spec system considers over
a dozen critical speci cations that impact the
overall performance of your vehicle, including
brake system performance, ride and handling,
traction control, and tire pressure monitoring
performance. GM’s TPC spec number is molded
onto the tire’s sidewall by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by a MS,
for mud and snow. SeeTire Sidewall Labeling
on page 287for additional information.

Different Size Tires and Wheels
If you add wheels or tires that are a different
size than your original equipment wheels and
tires, this may affect the way your vehicle
performs, including its braking, ride and handling
characteristics, stability, and resistance to
rollover. Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction
control, and stability control, the performance
of these systems can be affected.{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires
not recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use Saturn speci c wheel and
tire systems developed for your vehicle,
and have them properly installed by a
Saturn certi ed technician.
SeeBuying New Tires on page 296and
Accessories and Modi cations on page 233for
additional information.

Each new wheel should have the same
load-carrying capacity, diameter, width, offset and
be mounted the same way as the one it replaces.
{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
If you need to replace any of your wheels, wheel
bolts, or wheel nuts, replace them only with
new Saturn original equipment parts. This way,
you will be sure to have the right wheel, wheel
bolts, and wheel nuts for your vehicle.Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle ground
clearance, and tire clearance to the body
and chassis.{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause a crash. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if you need to, to get all the rust or
dirt off.
