Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and the
steel fuel door hinge unless the
components are plastic. Applying
silicone grease on weatherstrips
with a clean cloth will make them
last longer, seal better, and not stick
or squeak.
Use plain water to flush dirt and
debris from the vehicle's underbody.
Your dealer or an underbody car
washing system can do this. If not
removed, rust and corrosion can
develop.
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
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.

regularly clean the vehicle's interior.
Immediately remove any soils. Note
that newspapers or dark garments
that can transfer color to home
furnishings can also permanently
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
repellant from all interior surfaces or
permanent damage may result.
Your dealer may have products for
cleaning the interior. Use cleaners
specifically designed for the
surfaces being cleaned to prevent
permanent damage. To prevent
overspray, apply all cleaners directly
to the cleaning cloth. Cleaners
should be removed quickly. Never
allow cleaners to remain on the
surface being cleaned for extended
periods of time.
Cleaners may contain solvents that
can become concentrated in the
interior. Before using cleaners, read
and adhere to all safety instructions
on the label. While cleaning the
