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.
Notice:If you use extra
inhibitors and/or additives in
your vehicle’s cooling system,
you could damage your vehicle.
Use only the proper mixture of
the engine coolant listed in
this manual for the cooling
system. See Recommended
Fluids and Lubricants in the
Maintenance and Limited
Warranty and Owner Assistance
Information manual.Checking Coolant
The coolant reservoir is located in
the engine compartment on the
driver’s side of the vehicle.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
{CAUTION
Turning the coolant reservoir
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 coolant reservoir 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 KALT/COLD line.
Do not overll the coolant reservoir.
Too much coolant can result in
an overow condition when the
uid is hot.

Adding Coolant
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant reservoir, but only
when the engine is cool. If the
coolant reservoir is empty, a
special ll procedure is necessary.
SeeCooling System on page 9-12
for instructions on “How to Add
Coolant to the Coolant Reservoir.”
{CAUTION
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.
Pressure Cap
Notice:If the pressure cap is not
tightly installed, coolant loss
and possible engine damage may
occur. Be sure the cap is
properly and tightly secured.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
Engine Overheating
There is an engine coolant
temperature warning light on your
vehicle’s instrument panel. See
Engine Coolant Temperature
Warning Light on page 4-18for
more information.
If Steam Is Coming From
Your Engine
{CAUTION
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 re. 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.
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 4-18.
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.If you get the engine coolant
temperature warning with no sign of
steam, try this for a minute or so:
1. If your air conditioner is on,
turn it off.
2. In heavy traffic, let the engine
idle in N (Neutral) 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.

Power Steering Fluid
When to Check Power
Steering Fluid
It is not necessary to check the
power steering uid level. A power
steering uid leak is the only
reason for uid loss. If a leak
occurs, take your vehicle to the
dealer/retailer service department
and have it repaired as soon
as possible.
Windshield Washer Fluid
What to Use
When you need windshield
washer uid, 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 uid that has
sufficient protection against freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer uid
until the tank is full. SeeEngine
Compartment Overview on page 9-6
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. The reservoir is
lled with DOT-4 brake uid.
SeeEngine Compartment Overview
on page 9-6for the location of
the reservoir.
There are only two reasons why the
brake uid level in the reservoir
might go down:
The brake uid level goes down
because of normal brake lining
wear. When new linings are
installed, the uid level goes
back up.
A uid leak in the brake and/or
clutch hydraulic system can also
cause a low uid level. Have the
brake and/or clutch hydraulic
system xed, since a leak means
that sooner or later the brakes
and/or clutch will not work well.
Do not top off the brake/clutch uid.
Adding uid does not correct a leak.
If uid is added when the brake
linings are worn, there will be too
much uid when new brake linings
are installed. Add or remove uid, as
necessary, only when work is done
on the brake/clutch hydraulic system.
{CAUTION
If too much brake uid is added,
it can spill on the engine and
burn, if the engine is hot enough.
You or others could be burned,
(Continued)
CAUTION (Continued)
and the vehicle could be
damaged. Add brake uid only
when work is done on the brake
and/or clutch hydraulic system.
Refer toScheduled Maintenance on
page 11-3to determine when to
check the brake uid.
Checking Brake Fluid
The brake uid can be checked
without taking off the cap by looking
at the brake uid reservoir.
The uid level should be above
MIN. If it is not, have your brake
hydraulic system checked to see if
there is a leak. After work is
done on the brake hydraulic system,
make sure the level is above the
MIN but not over the MAX mark.

What to Add
Use only new DOT-4 brake uid
from a sealed container. It is
recommended that the brake
hydraulic system be ushed and
relled with new DOT-4 uid
at a regular maintenance service
every two years. SeeAdditional
Required Services on page 11-6
andRecommended Fluids and
Lubricants on page 11-12.
Always clean the brake uid
reservoir cap and the area around
the cap before removing it.
This helps keep dirt from entering
the reservoir.
{CAUTION
With the wrong kind of uid in
the brake hydraulic system,
the brakes might not work well.
This could cause a crash.
Always use the proper brake uid.Notice:
Using the wrong uid can badly
damage brake hydraulic system
parts. For example, just a few
drops of mineral-based oil,
such as engine oil, in the brake
hydraulic system can damage
brake 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. See
Exterior Cleaning on page 9-76.
Brake Wear
This vehicle has disc brakes.
Notice:Continuing to drive
with worn-out brake pads could
result in costly brake repair.
Front disc brake pads have built-in
brake pad 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 rmly.
{CAUTION
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.
Vehicle Service and Care 9-23

Rear disc brake pads do not have
built-in brake pad wear indicators.
Periodic visual inspection of the rear
brake pads is required to determine
when to replace the pads. Visually
inspect the rear brake pads
whenever the rear wheels are
removed such as during tire rotation.
1. Set the parking brake and make
sure that the brakes have been
given enough time to cool.
2. Remove the rear wheels.
3. Visually inspect the rear brake
inner pads (C) at each rear
wheel through the inspection
window in the brake caliper (A).Brake pads should be replaced
when the inner pad (C) is
worn to 5/64 in (2 mm) of pad
thickness (B). New brake pads,
with no wear, are 25/64 of
an inch (10 mm) thick.
4. After brake pad inspection or
replacement, install the rear
wheels.
Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or
lightly applied. This does not mean
something is wrong with the brakes.Properly torqued wheel bolts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear
and evenly tighten wheel bolts in
the proper sequence to torque
specications inCapacities
and Specifications on page 10-2.
Brake linings should always
be replaced as complete axle sets.
Brake Pedal Travel
See your dealer/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 that brake service might
be required.
Brake Adjustment
Every brake stop, the disc 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. The vehicle was
designed and tested with top-quality
brake parts. When parts of the
braking system are replaced — for
example, when the brake linings
wear down and new ones are
installed — be sure to get new
approved replacement parts. If this
is not done, the brakes might not
work properly. For example,
if someone puts in brake linings
that are wrong for the vehicle, the
balance between the front and
rear brakes can change — for the
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.
Battery
This vehicle has a maintenance free
battery. When it is time for a new
battery, see your dealer/retailer
for one that has the replacement
number shown on the original
battery’s label. SeeEngine
Compartment Overview on page 9-6
for 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.
Vehicle Storage
{CAUTION
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. SeeJump Starting
on page 9-69for tips on
working around a battery without
getting hurt.
Infrequent Usage: If the vehicle is
driven infrequently, remove the
black, negative (−) cable from the
battery. This helps keep the battery
from running down.
Extended Storage: For extended
storage of the vehicle, remove
the black, negative (−) cable from
the battery or use a battery
trickle charger. This helps maintain
the charge of the battery over
an extended period of time.

Headlamp Aiming
The optical headlamp aiming system
has been preset at the factory and
should need no further adjustment.
However, If the vehicle is damaged
in a crash, the headlamp aim may be
affected and adjustment may be
necessary.
If oncoming vehicles ash their high
beams at you, this may also mean
the vertical aim needs to be adjusted.
It is recommended that the vehicle
is taken to your dealer/retailer for
service if the headlamps need to be
re-aimed. It is possible however,
to re-aim the headlamps as
described.The vehicle should:Be placed so the headlamps
are 25 ft. (7.6 m) from a light
colored wall.
Have all four tires on a perfectly
level surface which is level all
the way to the wall.
Be placed so it is perpendicular
to the wall.
Not have any snow, ice, or
mudonit.
Be fully assembled and all other
work stopped while headlamp
aiming is being done.
Have a full tank of fuel and
one person or 160 lbs (75 kg)
on the driver seat.
Have all tires properly inated.
Headlamp aiming is done with
the vehicle’s low-beam headlamps.
The high-beam headlamps will
be correctly aimed if the low-beam
headlamps are aimed properly.To adjust the vertical aim on the
headlamps:
1. Open the hood. SeeHood
Release on page 9-5for
more information.
2. Locate the aim dot on the lens of
the low-beam headlamp.
3. Record the distance from the
ground to the aim dot on the
low-beam headlamp.
