Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI produces cars
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 corro-
sion 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, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
High-corrosion areas
If you live in an area where your vehi-
cle is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated cor-
rosion are road salts, dust control
chemicals, ocean air and industrial
pollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to
occur. For example, corrosion is
accelerated by high humidity, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact with the car surfaces by moisture
that is slow to evaporate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still
retain the moisture and promote cor-
rosion.
