4. Tyre ply composition and
material
The number of layers or plies of rub-
ber-coated fabric that are in the tyre.
Tyre manufacturers also must indi-
cate the materials in the tyre, which
include steel, nylon, polyester, and
others. The letter "R" means radial
ply construction; the letter "D" means
diagonal or bias ply construction;
and the letter "B" means belted-bias
ply construction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded
100.
The relative performance of tyres
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
tyres. The tyres available as standard
or optional equipment on your vehi-
cles may vary with respect to grade.

Maintenance
Low aspect ratio tyre
(if equipped)
Low aspect ratio tyres, whose aspect
ratio is lower than 50, are provided
for a sporty apperance.
Because the low aspect ratio tyres
are optimized for handling and brak-
ing, the vehicle may be more uncom-
fortable to travel in and there may be
more noise compared with normal
tyres.Because the sidewall of the low
aspect ratio tyre is shorter than
the normal, the wheel and tyre
of the low aspect ratio tyre is
more easily damaged. So, fol-
low the instructions below.
- When driving on a rough road
or off road, drive cautiously
because tyres and wheels may
be damaged. And after driving,
inspect tyres and wheels.
- When passing over a pothole,
speed bump, manhole, or kerb
stone, drive slowly so that the
tyres and wheels are not dam-
aged.
- If the tyre is impacted, we rec-
ommend that you inspect the
tyre condition or contact an
authorised HYUNDAI dealer.
- To prevent damage to the tyre,
inspect the tyre condition and
pressure every 3,000km.
CAUTION
•It is not easy to recognise tyre
damage visually. But if there
is the slightest hint of tyre
damage, even though you
cannot see it, have the tyre
checked or replaced as the
damage may lead to air leak-
age from the tyre.
•If the tyre is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or kerb
stone, it will not be covered by
the warranty.
•You can find out the tyre infor-
mation on the tyre sidewall.

Maintenance
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 vehicle 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 vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the vis-
ible surfaces but particularly to the
underside of the vehicle.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 vehicle clean and free
of corrosive materials. Attention to
the underside of the vehicle is partic-
ularly 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 vehicle at least
once a month and be sure to clean
the underside thoroughly when
winter is over.
• When cleaning underneath the
vehicle, give particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will
accelerate corrosion rather than
prevent it. Water under high pres-
sure 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 longer than is neces-
sary 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
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Observe the following
instructions to avoid CO poi-
soning.
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
whilst the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and the
catalytic converter system as
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.
