High-corrosion areas
If you live in an area where your car
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 corrosion.
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your car clean and free of mud
or accumulations of other materials.
This applies not only to the visible
surfaces but particularly to the
underside of the car.To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-
lowing:
Keep your vehicle clean
The best way to prevent corrosion is
to keep your car clean and free of
corrosive materials. Attention to the
underside of the car is particularly
important.
• If you live in a high-corrosion area
— where road salts are used, near
the ocean, areas with industrial
pollution, acid rain, etc.—, you
should take extra care to prevent
corrosion. In winter, hose off the
underside of your car at least once
a month and be sure to clean the
underside thoroughly when winter
is over.

Maintenance
84 7
• Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
• When the vehicle is stopped in an
open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with
the engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to
the emission control system.Operating precautions for catalyt-
ic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
• Make sure to refuel your vehicle
according to the "Fuel require-
ments" suggested in section 1.
• Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
• Do not misuse or abuse the
engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.
• Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
• Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
WARNING- Fire
• A hot exhaust system can
ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as grass, vegetation, paper,
leaves, etc.
• The exhaust system and cat-
alytic system are very hot
while the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.
