Maintenance
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end of
each winter. Pay special attention to
these areas because it is difficult to
see all the mud and dirt. It will do
more harm than good to wet down the
road grime without removing it. The
lower edges of doors, rocker panels,
and frame members have drain holes
that should not be allowed to clog with
dirt; trapped water in these areas can
cause rusting.
Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
• Do not use any abrasive cleaner,
polishing compound, solvent, or
wire brushes on aluminum
wheels.
• Clean the wheel when it has
cooled.
• Use only a mild soap or neutral
detergent, and rinse thoroughly
with water. Also, be sure to clean
the wheels after driving on salt-
ed roads.
• Do not wash the wheels with
high-speed car wash brushes.
• Do not use any cleanser con-
taining acid or alkaline deter-
gents.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, we produces vehicles of
the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner's
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
• Removal of paint or protective coat-
ings; by stones, gravel, abrasion or
minor scrapes and dents which
leave unprotected metal exposed to
corrosion.
NOTICE
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
