Maintenance
BODY AND INTERIOR MAINTENANCE
Body and hinges, lubricating
Door locksand loclccylinderscan be lubricated with an oil that
contains graphite.
Body and doorhinges, hood latch and doorcheclc rods should
be lubricated with
SAE 30 or SAE 40 engine oil. Lubricate
seat runners with multipurposegrease. Do not apply any oil to
rubber parts.
If door weather-strips are sticking, lubricate
them with silicone spray or talcum powder. The hood release
cable should be lubricated as well.
The use of winter
lock deicer sprays should be lkept to an
absolute minimum, as the alcohol in the deicer will wash the
grease out of the lock assemblies and may cause locks to
corrode internally or to become difficult to operate.
Exterior washing
The longer dirt is left on the paint, the greater the risk of dam-
aging theglossy finish,
eitherby scratching or by thechemical
effect dirt particles may have on the painted surface.
Do not wash the car in direct sunlight. If the engine hood is
warm, allow it to cool. Beads of water not only leave spots
when dried rapidly by the sun or heat from theengine, but also
can act as small magnifying glasses and burn spots into the
finish. Wash the car with a mixture of lukewarm water and a
car wash product. Rinse using plenty of clear water. Wipe the
body dry with a sofl cloth towel or chamois to prevent
water-spotting.
Interior care
Dirt spots can usually be removed with lultewarm soapy water
or a dry foam cleaner. Use spot remover for grease and oil
spots. Do not pour the liquid directly on the carpet or fabric,
but dampen a clean cloth and rub carefully, starting at the
edge of the spot and working inward. Do not use gasoline,
naphtha, or other flammable substances.
Leather upholstery and trim
Leather upholstery and trim should be periodically cleaned
using a slightly damp cotton or wool cloth. The idea is to get
rid of the dirt in the creases and pores that can cause brittle-
ness and premature aging. On heavily soiled areas, use a
mild detergent (such as
wooliteQ) or other specially formulat-
ed leather cleaners. Dry the trim and upholstery completely
