3. Fill the coolant surge tank with the proper mixture,to the COLD FILL line. Wait about five minutes,
then check to see if the level is below the COLD
FILL line. If the level is below the line, add additional
coolant to bring the level up to the line. Repeat
this procedure until the level remains constant at the
COLD FILL line for at least five minutes.
4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan. By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the COLD FILL line, add more of the proper mixture
to the coolant surge tank until the level reaches
the COLD FILL line.
5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see Engine Overheating on
page 6-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
•Give freezing protection down to −34°F (−37°C).
•Give boiling protection up to 265°F (129°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.
6-24

Notice:Using coolant other than DEX-COOL®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant in the
vehicle.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get too
hot but would not get the overheat warning.
WARNING: (Continued)
WARNING: (Continued)
The engine could catch fire and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice: If an improper coolant mixture is used, the
engine could overheat and be badly damaged. The
repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and other
parts.
If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
Notice: If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could be
damaged. Use only the proper mixture of the engine
coolant listed in this manual for the cooling system.
See Recommended Fluids and Lubricants on
page 7-10 for more information.
6-25

Checking Coolant
The coolant surge tank is located in the engine
compartment on the driver’s side of the vehicle. See
Engine Compartment Overview on page 6-12for more
information on location.
{WARNING:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap — even a
little — when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL line.
Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the coolant surge tank, but only
when the engine is cool. If the coolant surge tank is
empty, a special fill procedure is necessary. See Engine
Overheating on page 6-27 for instructions on “How to
Add Coolant to the Coolant Surge Tank.”
6-26

{WARNING:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Engine Overheating
You will find an engine coolant temperature warning
light on your vehicle’s instrument panel. See Engine
Coolant Temperature Warning Light on page 4-29 for
more information.
If Steam Is Coming From Your Engine
{WARNING:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away from
the vehicle until it cools down. Wait until there is no
sign of steam or coolant before you open the hood.
If you keep driving when your engine is overheated,
the liquids in it can catch fire. You or others could
be badly burned. Stop your engine if it overheats,
and get out of the vehicle until the engine is cool.
Notice: If the engine catches re because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.
6-27

If No Steam Is Coming From Your
Engine
An engine coolant temperature warning can indicate a
serious problem. SeeEngine Coolant Temperature
Warning Light on page 4-29 .
If you get an engine coolant temperature warning, but
see or hear no steam, the problem may not be too
serious. Sometimes the engine can get a little too hot
when you:
•Climb a long hill on a hot day.
•Stop after high-speed driving.
•Idle for long periods in traffic.
•Tow a trailer.
If you get the engine coolant temperature warning with
no sign of steam, try this for a minute or so: 1. If you have an air conditioner and it is on, turn it off.
2. In heavy traffic, let the engine idle in N (Neutral) for automatic transmission or NEUTRAL for manual
transmission, while stopped. If it is safe to do so, pull
off the road, shift to P (Park) or N (Neutral) and let
the engine idle.
3. Turn on your heater to full hot at the highest fan speed and open the windows as necessary. If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the engine
for three minutes while you are parked. If you still have
the warning, turn off the engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
6-28

Adding Washer Fluid
Open the cap with the
washer symbol on it. Add
washer fluid until the tank is
full. SeeEngine
Compartment Overview on
page 6-12 for reservoir
location.
Notice:
When using concentrated washer uid, follow
the manufacturer’s instructions for adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts of
the washer system. Also, water does not clean as
well as washer uid.
Fill the washer uid tank only three-quarters full
when it is very cold. This allows for uid
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage the vehicle’s
windshield washer system and paint.
Brakes
Brake Fluid
The brake master
cylinder and, on manual
transmission vehicles,
the clutch hydraulic system
use the same reservoir
filled with DOT 3
brake fluid.
See Engine Compartment Overview on page 6-12 for
the location of the reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down:
•The brake fluid level goes down because of normal
brake lining wear. When new linings are installed,
the fluid level goes back up.
•A fluid leak in the brake and/or clutch hydraulic
system can also cause a low fluid level. Have
the brake and/or clutch hydraulic system fixed, since
a leak means that sooner or later the brakes
and/or clutch will not work well.
6-29

Do not top off the brake/clutch fluid. Adding fluid does
not correct a leak. If fluid is added when the brake
linings are worn, there will be too much fluid when new
brake linings are installed. Add or remove fluid, as
necessary, only when work is done on the brake/clutch
hydraulic system.
{WARNING:
If too much brake fluid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake fluid only when work is
done on the brake and/or clutch hydraulic system.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4-26.
What to Add
Use only new DOT 3 brake fluid from a sealed container.
See Recommended Fluids and Lubricants on page 7-10 .
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This helps keep
dirt from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake or clutch
hydraulic system, the brakes or clutch might not
work well. This could cause a crash. Always use
the proper brake fluid.
6-30

Notice:
Using the wrong uid can badly damage brake
or clutch hydraulic system parts. For example,
just a few drops of mineral-based oil, such
as engine oil, in the brake or clutch hydraulic
system can damage brake or clutch hydraulic
system parts so badly that they will have
to be replaced. Do not let someone put in the
wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged. Be
careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 6-97 .
Brake Wear
This vehicle has front disc brakes and could have rear
drum brakes or rear disc brakes.
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
can come and go or be heard all the time the vehicle is
moving, except when applying the brake pedal firmly.
{WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes.
6-31

Notice:If you leave the radio or other accessories
on during the jump starting procedure, they could be
damaged. The repairs would not be covered by the
warranty. Always turn off the radio and other
accessories when jump starting the 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!
4. Open the hood on the other vehicle and locate the positive (+) and negative ( −) terminal locations on
that vehicle.
You will not see the battery of your vehicle under
the hood. It is located in the trunk. You will not need
to access your battery for jump starting. The vehicle
has a remote positive (+) and a remote negative ( −)
jump starting terminal. Locate the remote
positive (+) terminal which
is located under a red
tethered cap on the engine
compartment fuse block.
Lift the cap to access
the terminal.
Locate the remote
negative (−) ground
terminal, marked GND ( −),
which is located behind
the engine coolant
surge tank.
See Engine Compartment Overview on page 6-12
for more information on the location of the
positive (+) and negative ( −) terminals on the
vehicle.

{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. 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.WARNING: (Continued)
WARNING: (Continued)
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. 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,
explosive gas could be present.
Battery fluid contains acid that can burn you. Do
not 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.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
