Bright-metal maintenance
• Use a tar remover to remove road
tar and insects, not scraping or
using a sharp object.
• To protect a bright metal surface
from corrosion, apply a coat of wax
or chrome preservative, or polish
the surface.
• In winter or in coastal areas, apply
a bright metal part with a heavy
coat of wax or preservative. If nec-
essary, coat the part with non-cor-
rosive petroleum jelly or other pro-
tective compound.
Underbody maintenance
Corrosive materials, which are used
to remove ice, snow or dusts, may
accumulate across
underbody. When these materials
are not promptly removed, rusting
process may accelerate across the
underbody, such as the fuel lines,
frame, floor pan and exhaust system,
regardless of the rust-protection
treatment.
Thoroughly wash the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after driving off a road, or after the
winter season. Pay special attention
to the underbody areas to find any
mud or dirt. Remaining road dirt or
grime across the vehicle underbody
does more harm than good. The
lower edges of doors, rocker panels,
and frame members have drain
holes, which should not be clogged
with dirt; clogging in these areas may
cause rusting.
After washing the vehicle, test
the brakes by slowly applying
them to check whether they are
affected by water. When braking
performance is impaired, dry
the brakes by lightly applying
them while driving forward at a
slow 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
the vehicle
finish.
• Clean the wheel, while it is cool.
• Use only a mild soap or neutral
detergent, and thoroughly rinse
with water. Also, always clean the
wheels after driving on a salted
road. This prevents corrosion.
• Avoid washing the wheels with an
automatic high-speed washing
brush.
• Do not use any alkaline or acid
detergent. It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.
