antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of
vehicle control or damage to
paint and body trim.

amounts of alcohol and can
be flammable under certain
circumstances. Do not allow

the washer fluid or the
washer fluid reservoir.

MAINTENANCE
7-38When choosing an oil, consider the range
of temperature your vehicle will be
operated in before the next oil change.
Then select the recommended oil
viscosity from the chart.EXTERIOR CAREEXTERIOR GENERAL
CAUTIONIt is very important to follow the
manufacturer’s directions when using
any chemical cleaner or polish. Read all
warning and caution statements that
appear on the label.FINISH MAINTENANCE
WASHINGTo help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
special attention to the removal of any
accumulation of salt, dirt, mud, or other
foreign materials. Make sure the drainholes in the lower edges of the doors and
rocker panels are kept clear and clean.
Insects, tar, tree sap, bird droppings,
industrial fallout and similar deposits can
damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, can be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
WAXINGWax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim as well,
to protect it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.
✻
NOTICE
Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
CAUTION
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow
forward speed.
