Underbody maintenance
Corrosive materials used for ice and snow
removal and dust control may collect 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. 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.
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.
• Do not use 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, clean the wheels after
driving on salted roads.
• Do not wash the wheels with
high-speed car wash brushes.
• Do not use any cleaners containing acid
or alkaline detergents.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat
corrosion, HYUNDAI 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 corrosion on
your vehicle are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath the
vehicle.
• Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave
unprotected metal exposed to
corrosion.
High-corrosion areas
If you live in an area where your vehicle is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
