Vehicle Care 185.
Helps keep the proper engine
temperature
CautionDo not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard
GMW3420 and clean, drinkable
water. Anything else can cause
damage to the engine cooling
system and the vehicle, which
would not be covered by the
vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health. Checking Coolant The vehicle must be on a level
surface when checking the coolant
level.
It is normal to see coolant moving in
the upper coolant hose return line
when the engine is running.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge 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 mark
pointed to, add a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.
If no coolant is visible in the coolant
surge tank, add coolant as follows: How to Add Coolant to the
Coolant Surge Tank
{ WarningSteam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
{ Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.

242 Vehicle Care Caution (Continued)This could cause damage that
would not be covered by the
vehicle warranty.
If using an automatic car wash,
follow the car wash instructions. The
windshield wiper and rear window
wiper, if equipped, must be off.
Remove any accessories that may
be damaged or interfere with the car
wash equipment.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
Convertible Top Care
Frequently hand wash convertible
tops with mild car wash soap. Never
use a stiff brush, steam, bleach,
or aggressive cleaners. If necessary, a soft brush can be
used to remove dirt. When finished
cleaning, thoroughly rinse the fabric.
Avoid automatic car washes with
overhead brushes or very high
pressure sprays as they can cause
damage and leaking.
Only lower the top when it is
completely dry and avoid leaving
the top lowered for extended
periods of time to prevent excessive
interior weathering.
Avoid leaving large amounts of
snow on the top for extended
periods of time as damage may also
occur.
Finish Care Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces
are damaged, see your dealer to
have the damage assessed and
repaired. Foreign materials such as
calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle's finish if they remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See
your dealer for approved cleaning
products.
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur.
Caution
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.

246 Vehicle Care corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting Airborne pollutants can fall upon
and attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See “ Finish Care ”
previously in this section.
Interior Care To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils.
Newspapers or dark garments can
transfer color to the vehicle ’ s
interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild
soap solution, immediately remove
hand lotions, sunscreen, and insect
repellent from all interior surfaces or
permanent damage may result. Use cleaners specifically designed
for the surfaces being cleaned to
prevent permanent damage. Apply
all cleaners directly to the cleaning
cloth. Do not spray cleaners on any
switches or controls. Remove
cleaners quickly.
Before using cleaners, read and
follow all safety instructions on the
label. While cleaning the interior,
open the doors and windows to get
proper ventilation.
To prevent damage, do not clean
the interior using the following
cleaners or techniques:
.
Never use a razor or any other
sharp object to remove soil from
any interior surface.
.
Never use a brush with stiff
bristles.
.
Never rub any surface
aggressively or with too much
pressure.
.
Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners,
use approximately 20 drops per 3.8 L (1 gal) of water.
A concentrated soap solution will
create streaks and attract dirt.
Do not use solutions that contain
strong or caustic soap.
.
Do not heavily saturate the
upholstery when cleaning.
.
Do not use solvents or cleaners
containing solvents.
Interior Glass To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning with
plain water.
Caution
To prevent scratching, never use
abrasive cleaners on automotive
glass. Abrasive cleaners or
aggressive cleaning may damage
the rear window defogger.
