is not harmful to painted surfaces and is
specifically intended for your purposes.
Follow the manufacturer’s directions when
using these special cleaners.
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.
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.
Repair finish damage
Carefully examine your vehicle for damage
to the painted surfaces. Should you find
any chips or scratches in the paint, touch
them up immediately to prevent corrosion
from starting. If the chips or scratches have
gone through to the bare metal, have a
qualified body shop make the repair.

How to Help Prevent Corrosion
Common causes of corrosion
1) Accumulation of road salt, dirt, mois-
ture, 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 abra-
sion by stones and gravel.
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.
Keep passenger and luggage compart-
ments clean
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.
Moisture, dirt or mud can accumulate
under the floor mats and may cause corro-
sion. Occasionally, check under these
mats to ensure that this area is clean and
dry. More frequent checks are necessary if
the vehicle is used off road or in wet
weather.
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.
Certain cargos such as chemicals, fertiliz-
ers, cleaners, salts, etc. are extremely cor-
rosive by nature. These products should
be transported in sealed containers. If a
spill or leak does occur, clean and dry the
area immediately.
For washing instructions, refer to the “Vehi-
cle 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

erated rate of corrosion to parts of the
