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 rust-
ing.

WARNING
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.

Aluminum wheel maintenance

The aluminum wheels are coated
with a clear protective finish.
CAUTION
• Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminum
wheels.
• Clean the wheel when it has
cooled.

tral detergent, and rinse thor-
oughly with water. Also, clean
the wheels after driving on
salted roads.
• Do not wash the wheels with
high-speed car wash brushes.

taining acid or alkaline or acid
