How to Add Coolant to the Coolant
Surge Tank If you have not found a problem yet, check to see if
coolant is visible in the surge tank. 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 surge tank,
but be sure the cooling system, including the coolant
surge tank pressure cap, is cool before you do it.
See Engine Coolant on page 5-24 for more information.
If no coolant is visible in the surge tank, add coolant
as follows:
{ CAUTION: Steam and scalding liquids from a hot cooling
system can blow out and burn you badly.
They are under pressure, and if you turn the
radiator pressure cap — even a little — they
can come out at high speed. Never turn the
cap when the cooling system, including the
radiator pressure cap, is hot. Wait for the
cooling system and radiator pressure cap to
cool if you ever have to turn the pressure cap. { 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. 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.
Notice: In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

Tire Terminology and Denitions 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,
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. See Inflation - Tire Pressure
on page 5-62 .
Curb Weight :
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 Identication Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR :
Gross Vehicle Weight Rating.
See Loading Your Vehicle on page 4-35 .
GAWR FRT :
Gross Axle Weight Rating for
the front axle. See Loading Your Vehicle on
page 4-35 .

Spare Tire Your vehicle, when new, had a fully-inated spare tire.
A spare tire may lose air over time, so check its
ination pressure regularly. See Inflation - Tire Pressure
on page 5-62 and Loading Your Vehicle on page 4-35
for information regarding proper tire ination and loading
your vehicle. For instruction on how to remove, install
or store a spare tire, see Removing the Flat Tire
and Installing the Spare Tire on page 5-85 and Storing
a Flat or Spare Tire and Tools on page 5-94 .
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. The spare tire is made to perform well
at speeds up to 70 mph (112 km/h) at the recommended
ination pressure, so you can nish your trip.
Have the damaged or at road tire repaired or replaced
as soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in case
you need it again. Do not mix tires and wheels of
different sizes, because they will not t. Keep your
spare tire and its wheel together. Appearance Care Interior Cleaning Your vehicle’s interior will continue to look its best if it is
cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
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 your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your 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.
5-98

Notice: If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger. When cleaning the glass on your
vehicle, use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your vehicle’s
interior, maintain adequate ventilation by opening
your vehicle’s doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your dealer/retailer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your dealer/retailer to remove
odors from your vehicle’s upholstery. Do not clean your vehicle using the following cleaners
or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure
can damage your interior and does not improve the
effectiveness of soil removal.
Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers.
Using too much soap will leave a residue that
leaves streaks and attracts dirt. For liquid cleaners,
about 20 drops per gallon (3.78 L) of water is a
good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result from
the use of many organic solvents such as naptha,
alcohol, etc.

The proper replacement parts, uids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 6-13 and Maintenance Replacement Parts
on page 6-15 . When your vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance To maintain the ride, handling, and performance of your
vehicle, it is important that the rst tire rotation service
be performed when the vehicle has 5,000 to 8,000 miles
(8 000 to 13 000 km). Check tires for ination pressures
and wear. See Tires on page 5-56 . Rotate tires. See
Tire Inspection and Rotation on page 5-69 and
“Tire Wear Inspection” in At Least Once a Month on
page 6-10 . When the CHANGE ENGINE OIL SOON message
comes on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions, the
engine oil life system may not indicate that vehicle
service is necessary for over a year. However,
the engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your dealer/retailer has trained service technicians who
will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-16 for information on
the Engine Oil Life System and resetting the system.
