Engine Coolant
The cooling system in the vehicle is
lled with DEX-COOL®engine
coolant. The coolant is designed to
remain in the vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst.
The following explains the cooling
system and how to check and
add coolant when it is low. If there
is a problem with engine
overheating, seeEngine
Overheating on page 5-20.
What to Use
{CAUTION
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.
(Continued)
CAUTION (Continued)
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 you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture, nothing
else needs to be added. This
mixture:
Gives freezing protection down to
−34°F (−37°C), outside
temperature.
Gives boiling protection up to
265°F (129°C), engine
temperature.
Protects against rust and
corrosion.
Will not damage aluminum parts.
Helps keep the proper engine
temperature.
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 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.
SeeRecommended Fluids
and Lubricants on page 6-12for
more information.

Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant recovery tank. If the
coolant inside the coolant recovery
tank is boiling, do not do anything
else until it cools down. If coolant is
visible but the coolant level is not at
or above the FULL COLD mark, add
a 50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant recovery tank, but be sure
the cooling system is cool before this
is done. SeeEngine Coolant on
page 5-17for more information.
The coolant recovery tank cap has
this symbol on it.When the engine is cold, the
coolant level should be at or above
the FULL COLD line marked on
the recovery tank.
When the engine is hot, the level
could be higher than the FULL
COLD line. If the coolant is below
the FULL COLD line when the
engine is hot, there could be a leak
in the cooling system.
If the coolant is low, add the coolant
or take the vehicle to a
dealer/retailer for service.
How to Add Coolant to the
Recovery Tank
{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.Notice:This vehicle has a
specic coolant ll procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If coolant is needed, add the proper
DEX-COOL
®coolant mixture at
the coolant recovery tank.
How to Add Coolant to the
Radiator
{CAUTION
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
5-18 Service and Appearance Care

If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating
Mode” next in this section.Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signicant loss in
power and engine performance. The
temperature gage indicates an
overheat condition exists. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.Notice:After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to
cool before attempting any repair.
The engine oil will be severely
degraded. Repair the cause
of coolant loss, change the oil
and reset the oil life system. See
Engine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir is
located toward the front of the engine
compartment on the passenger
side of the vehicle. SeeEngine
Compartment Overview on
page 5-10for reservoir location.
5-22 Service and Appearance Care

When to Check Power
Steering Fluid
It is not necessary to regularly
check power steering uid unless
you suspect there is a leak in
the system or you hear an unusual
noise. A uid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering uid:
1. Turn the key off and let the
engine compartment cool down.
2. Remove engine oil ll cap.
3. Slide engine cover rearward and
lift to remove.
4. Wipe the cap and the top of the
reservoir clean.
5. Unscrew the cap and wipe the
dipstick with a clean rag.6. Replace the cap and completely
tighten it.
7. Remove the cap again and look
at the uid level on the dipstick.
The uid level should be somewhere
between MAX and MIN line on the
dipstick in room temperature. If the
uid is on or below MIN line, you
should add uid close to MAX Line.
What to Use
To determine what kind of uid to
use, seeRecommended Fluids and
Lubricants on page 6-12. Always
use the proper uid.
Notice:Use of the incorrect uid
may damage the vehicle and
the damages may not be covered
by the vehicle’s warranty.
Always use the correct uid
listed inRecommended Fluids
and Lubricants on page 6-12.
Windshield Washer Fluid
What to Use
When adding windshield washer
uid, be sure to read the
manufacturer’s instructions before
use. If the vehicle will be operating in
an area where the temperature may
fall below freezing, use a uid that
has sufficient protection against
freezing.
Service and Appearance Care 5-23

A uid leak in the brake hydraulic
system can also cause a low uid
level. Have the brake hydraulic
system xed, since a leak means
that sooner or later the brakes will
not work well.
Do not top off the brake uid. Adding
uid does not correct a leak. If uid is
added when the linings are worn,
there will be too much uid when new
brake linings are installed. Add or
remove brake uid, as necessary,
only when work is done on the brake
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, and the
vehicle could be damaged. Add
brake uid only when work is done
on the brake hydraulic system.When the brake uid falls to a low
level, the brake warning light comes
on. SeeBrake System Warning
Light on page 3-33.
What to Add
Use only new DOT-3 brake uid
from a sealed container. See
Recommended Fluids and
Lubricants on page 6-12.
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. SeeWashing
Your Vehicle on page 5-86.

heat shield by pulling the
rubber latch. Store the plastic
spare tire heat shield. See
Storing a Flat or Spare Tire and
Tools on page 5-80for more
information.
{CAUTION
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. SeeChanging a Flat
Tire on page 5-71.
{CAUTION
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle’s wheel
could fall off, causing a crash.

Compact Spare Tire
The compact spare tire, if the
vehicle has one, was fully inated
when the vehicle was new, however,
it can lose air after a time. Check
the ination pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare
on the vehicle, stop as soon
as possible and make sure the
spare tire is correctly inated. The
compact spare is made to perform
well at speeds up to 65 mph
(105 km/h) for distances up to
3,000 miles (5 000 km), so you can
nish your trip and have the
full-size tire repaired or replaced at
your convenience. Of course, it
is best to replace the spare with a
full-size tire as soon as possible.
The spare tire will last longer and
be in good shape in case it is
needed again.Notice:When the compact spare
is installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.
And do not mix the compact spare
tire or wheel with other wheels
or tires. They will not t. Keep the
spare tire and its wheel together.
The All-Wheel Drive (AWD) system
will be automatically disabled
when you use the compact spare.
To restore the AWD and prevent
excessive wear on the clutch in your
AWD, replace the compact spare
tire with a full-size tire as soon
as possible.
Notice:Tire chains will not t the
compact spare. Using them can
damage the vehicle and can
damage the chains too. Do not use
tire chains on the compact spare.
Appearance Care
Interior Cleaning
The vehicle’s interior will continue
to look its best if it is cleaned often.
Although not always visible, dust
and dirt can accumulate on the
upholstery. Dirt can damage carpet,
fabric, leather, and plastic surfaces.
Regular vacuuming is recommended
to remove particles from the
upholstery. It is important to keep
the upholstery from becoming and
remaining heavily soiled. Soils
should be removed as quickly as
possible. The vehicle’s interior may
experience extremes of heat that
could cause stains to set rapidly.
Lighter colored interiors may
require more frequent cleaning.
Use care because newspapers and
garments that transfer color to home
furnishings may also transfer color
to the vehicle’s interior.
Service and Appearance Care 5-83

When cleaning the vehicle’s interior,
only use cleaners specically
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only on
glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the
cleaning cloth.
Notice:Using abrasive cleaners
when cleaning glass surfaces
on the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the
vehicle, use only a soft cloth and
glass cleaner.Many cleaners contain solvents that
may become concentrated in the
vehicle’s breathing space. Before
using cleaners, read and adhere to
all safety instructions on the
label. While cleaning the vehicle’s
interior, maintain adequate
ventilation by opening the vehicle’s
doors and windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the vehicle’s upholstery and
clean the vehicle’s glass can be
obtained from your dealer/retailer.Do not clean the vehicle using:
A knife or any other sharp object
to remove a soil from any interior
surface.
A stiff brush. It can cause
damage to the vehicle’s interior
surfaces.
Heavy pressure or aggressive
rubbing with a cleaning cloth. Use
of heavy pressure can damage
the interior and does not improve
the effectiveness of soil removal.
Laundry detergents or
dishwashing soaps with
degreasers can leave residue that
streaks and attracts dirt. For liquid
cleaners, about 20 drops per
gallon (3.78 L) of water is a good
guide. Use only mild, neutral-pH
soaps.
Too much cleaner that saturates
the upholstery.
Organic solvents such as naptha,
alcohol, etc. that can damage the
vehicle’s interior.
5-84 Service and Appearance Care

Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment frequently to
remove dust and loose dirt.
A canister vacuum with a beater bar
in the nozzle may only be used
on oor carpet and carpeted oor
mats. For any soil, always try
to remove it rst with plain water or
club soda. Before cleaning,
gently remove as much of the soil
as possible using one of the
following techniques:
For liquids: gently blot the
remaining soil with a paper towel.
Allow the soil to absorb into
the paper towel until no more can
be removed.
For solid dry soils: remove as
much as possible and then
vacuum.
To clean:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess
moisture.3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled
area until the cleaning cloth
remains clean.
5. If the soil is not completely
removed, use a mild soap
solution and repeat the cleaning
process that was used with
plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When
a commercial upholstery cleaner or
spot lifter is to be used, test a
small hidden area for colorfastness
rst. If the locally cleaned area
gives any impression that a
ring formation may result, clean the
entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture
from the fabric or carpet.
Leather
A soft cloth dampened with water
can be used to remove dust. If
a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can
be used. Allow the leather to dry
naturally. Do not use heat to
dry. Never use steam to clean
leather. Never use spot lifters or
spot removers on leather. Many
commercial leather cleaners
and coatings that are sold to
preserve and protect leather may
permanently change the appearance
and feel of the leather and are not
recommended. Do not use
silicone or wax-based products, or
those containing organic solvents to
clean the vehicle’s interior because
they can alter the appearance
by increasing the gloss in a
non-uniform manner. Never use
shoe polish on leather.
