Maintenance
Keep paint and trim in good con-
dition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as
soon as possible.
Don't neglect the interior
Moisture can collect under the floor
mats and carpeting and cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fertil-
izers, cleaning materials or chemi-
cals in the car.
These should be carried only in
proper containers and any spills or
leaks should be cleaned up, flushed
with clean water and thoroughly
dried.Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er, and air freshener from contacting
the interior parts because they may
cause damage or discoloration. If
they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to
clean vinyl.
CAUTION- Electrical components
Never allow water or other liq-uids to come in contact withelectrical/electronic compo-nents inside the vehicle as thismay damage them.
CAUTION - Leather
When cleaning leather products(steering wheel, seats etc.), useneutral detergents or low alco-hol content solutions. If you usehigh alcohol content solutionsor acid/alkaline detergents, thecolor of the leather may fade orthe surface may get stripped off.
