Maintenance
tem, 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 the
doors, rocker panels, and frame
members have drain holes that
should not clog with dirt; trapped
water in these areas can cause
rusting.
WARNING
After washing the vehicle, test the
brakes whilst driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.
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. They may scratch or
damage the finish.
