Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated 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 underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial 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. G230106AUN-EA
Aluminium wheel maintenance
The aluminium wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminium wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any acid detergent. It may damage and corrode the aluminium
wheels coated with a clear protectivefinish.
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 for-
ward speed.
