4. Tire ply composition and
material
The number of layers or plies of rub-
ber-coated fabric are in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amountof air pressure that should be put inthe tire. Do not exceed the maximumpermissible inflation pressure. Referto the Tire and Loading Informationlabel for recommended inflationpressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tr e a d w e a r
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.

Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for spor ty looks.
Because the low aspect ratio tires
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tires.
Because the sidewall of the low
aspect ratio tire is shorter than
the normal, the wheel and tire of
the low aspect ratio tire is easi-
er to be damaged. So, follow the
instructions below.
- When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.
- When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.
- If the tire is impacted, we rec-
ommend that you inspect the
tire condition or contact an
authorized HYUNDAI dealer.
- To prevent damage to the tire,
inspect the tire condition and
pressure every 3,000km.
CAUTION
•It is not easy to recognize the
tire damage with your own
eyes. But if there is the slight-
est hint of tire damage, even
though you cannot see the
tire damage with your own
eyes, have the tire checked or
replaced because the tire
damage may cause air leak-
age from the tire.
•If the tire is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.

Maintenance
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
Yo u c a n h e l p p r e v e n t c o r r o s i o n f r o m
getting started by observing the fol-
lowing:
Keep your car 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.
• When cleaning underneath the car,
give particular attention to the
components under the fenders and
other areas that are hidden from
view. Do a thorough job; just damp-
ening the accumulated mud rather
than washing it away will acceler-
ate corrosion rather than prevent
it. Water under high pressure and
steam are particularly effective in
removing accumulated mud and
corrosive materials.

Maintenance
•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 cat-
alytic converters (if equipped)
Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-
ing.
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 dry grass, 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.
