Corrosion Prevention
It is important to take good care of your
vehicle to protect it from corrosion.
Listed below are instructions for how to
maintain your vehicle to prevent corrosion.
Please read and follow these instructions
carefully.
Important Information About Corro-
sion
Common causes of corrosion
1) Accumulation of road salt, dirt, moisture
or chemicals in hard-to-reach areas of
the vehicle underbody or frame.
2) Chipping, scratches and any damage to
treated or painted metal surfaces
resulting from minor accidents or
impact from stones and gravel.
Environmental conditions which accel-
erate corrosion
1) Road salt, dust control chemicals, sea
air or industrial pollution will all acceler-
ate the corrosion of metal.
2) High humidity will increase the rate of
corrosion particularly when the temper-
ature range is just above the freezing
point.
3) Moisture in certain areas of a vehicle
for an extended period of time may pro-
mote corrosion even though other body
sections may be completely dry.
4) High temperatures will cause an accel-
erated rate of corrosion to parts of the
vehicle which are not well ventilated to
permit quick drying.

This information illustrates the necessity of
keeping your vehicle (particularly the
underbody) as clean and dry as possible. It
is equally important to repair any damage
to the paint or protective coatings as soon
as possible.
How to Help Prevent Corrosion
Wash your vehicle frequently
The best way to preserve the finish on your
vehicle and to help avoid corrosion is to
keep it clean with frequent washing.
Wash your vehicle at least once during the
winter and once immediately after the win-
ter. Keep your vehicle, particularly the
underside, as clean and dry as possible.
If you frequently drive on salted roads, your
vehicle should be washed at least once a
month during the winter. If you live near the
ocean, your vehicle should be washed at
least once a month throughout the year.
Wash your vehicle immediately after using
it off-road. For washing instructions, refer
to the “Vehicle Cleaning” section.
Remove foreign material deposits
Foreign material such as salts, chemicals,
road oil or tar, tree sap, bird droppings and
industrial fall-out may damage the finish of
your vehicle if it is left on painted surfaces.
Remove these types of deposits as quickly
as possible. If these deposits are difficult to
wash off, an additional cleaner may be
required. Be sure that any cleaner you use
is not harmful to painted surfaces and is
specifically intended for your purposes.
Follow the manufacturer’s directions when
using these special cleaners.
WARNING
Foreign material can lodge between
the fuel tank of your vehicle and the
skid plate which covers it. You should
periodically clean out any foreign
material which has accumulated in
this area, since it could create a fire
hazard.
