Protecting your Toyota from
corrosion
Toyota, through its diligent research, de-
sign
and
use
of
the
most
technology available, has done its part to
help prevent corrosion and has provided
you
with
the
finest
quality
construction. Now, it is up to you. Proper
care of your Toyota can help ensure long−
term corrosion prevention.
The most common causes of corrosion
to your vehicle are:
D
The accumulation of road salt, dirt and
moisture in hard−to−reach areas under
the vehicle.
D
Chipping
of
paint,
or
undercoating
caused
by
minor
accidents
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:
D
Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea−
coast or in areas of industrial pollution.
D
High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.

D
Wetness or dampness to certain parts
advanced
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
vehicle
be dry.
D
High ambient temperatures can cause
corrosion to those components of the
vehicle
which
quick−drying due to lack of proper ven-
tilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.

To
help
prevent
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:
D
If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.
D
Pay particular attention to the vehicle's
underside and wheel housings as it is
difficult to see all the mud and dirt. It
will do more harm than good to simply
wet the mud and debris without remov-
ing them. The lower edge of doors,
rocker panels and frame members have
drain holes which should not be al-
are
prevented
from
lowed to clog with dirt as trapped wa-
ter in these areas can cause corrosion.
D
Wash the underside of the vehicle thor-
oughly when winter is over.
See "Washing and waxing your Toyota" for
more tips.
Check the condition of your vehicle's
corrosion
on
your
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.
