Corrosion protection
Protecting your vehicle from corro-
sion
HYUNDAI produces a vehicle of the
highest quality by using the most
advanced design and construction
practices to combat
However, this is only one part of anti-
corrosion resistance practices. To
achieve a long-term corrosion resist-
ance of your vehicle, your coopera-
tion and assistance are required.
Common causes of corrosion
The followings are the most common
causes of corrosion:
• Road salt, dirt and moisture, which
accumulate across the vehicle
underbody.
• Exposure of an unprotected metal
to corrosion due to the removal of
paint or protective coat, possibly by
a stone, gravel, abrasion, minor
scrape, or dent.
High-corrosion areas
In an area, where your vehicle is reg-
ularly exposed to corrosive materi-
als, an anti-corrosion measure is
particularly important. Some of the
common causes of instant vehicle
corrosion are road salts, dust, chem-
icals, salty air and industrial pollu-
tants.

Moisture breeds corrosion
Moisture creates a condition in which
corrosion is most likely to occur. For
example, a corrosion process is
accelerated by high humidity, partic-
ularly when a temperature is just
above the freezing point. In such

condition, the vehicle surface is kept
in contact with moisture that is slow
to evaporate.
Mud
because it is slow to dry and holds
moisture in contact with the vehicle.
Although the mud appears to be dry,
it may still retain some moisture
inside and promote corrosion.
A high temperature also accelerates
a corrosion process, when the air is
unventilated, and when the moisture
pervades. For all these reasons, it is
particularly important to keep your
vehicle clean, and remove mud or
any other accumulated substances.
This applies not only to the visible
surfaces but particularly to the vehi-
cle underbody.
To help prevent corrosion
You can prevent corrosion from the
start by following the below precau-
tions.
