WEATHERSTRIP LUBRICATION

All weatherstrips should be periodically lubricated (minimum of every
six months) with a silicone grease lubricant. A thin film of silicone
grease lubricant should be applied using a clean cloth. Silicone grease
application will lengthen weatherstrip life, help sealing, and assist in
eliminating squeaks.

CORROSION PROTECTION

Your vehicle has been designed and built to resist corrosion. Special
materials and protective finishes were used on most parts of your
vehicle when it was built to help maintain good appearance, strength,
and reliable operation. However, some parts which normally are not
visible (such as those under the vehicle and under the hood) are such
that surface rust will not affect their reliability. So corrosion protection
is not needed or used on these parts.

Sheet Metal Damage

If your vehicle is damaged and requires sheet metal repair or
replacement, make sure the body repair shop applies anti-corrosion
material to the parts repaired or replaced so that corrosion protection
is restored. (Also see "Finish Damage" which follows.)

Foreign Material Deposits

Calcium chloride and other salts, ice-melting agents, road oil and tar,
tree sap, bird droppings, chemicals from industrial chimneys and other
foreign matter may damage vehicle finishes if left on painted surfaces.
Prompt washing may not completely remove all of these deposits.
Other cleaners may be needed. When using chemical cleaners, be
sure they are safe for use on painted surfaces.
Finish Damage
Any stone chips, fractures or deep scratches in the finish should be
repaired promptly. Bare metal will corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be repaired with touchup materials
available from your authorized dealer or other service outlets. Larger
areas of finish damage can be corrected in your dealer's body and
paint shop.
