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 5 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 ªEngine Overheatingº in
the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you use
only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX
-COOL is not
covered by your new vehicle warranty.

Use a clean cloth or sponge, and change to a
clean area often. A soft brush may be used if stains
are stubborn.

If a ring forms on fabric after spot cleaning, clean the
entire area immediately or it will set.
Cleaning Vinyl
Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.

Things like tar, asphalt and shoe polish will stain if you
don't get them off quickly. Use a clean cloth and a
vinyl/leather cleaner. See your dealer for this product.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let the
leather dry naturally. Do not use heat to dry.

For stubborn stains, use a leather cleaner. See your
dealer for this product.

Never use oils, varnishes, solvent
-based or abrasive
cleaners, furniture polish or shoe polish on leather.
Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the
finish, it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft c
loth or sponge. Commercial cleaners may affect the
surface finish.
Cleaning Wood Panels
Use a clean cloth moistened in warm, soapy water (use
mild dish washing soap). Dry the wood immediately
with a clean cloth.
Cleaning Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker won't be damaged. Clean spots with just water
and mild soap.
