Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyreinflation pressure matches the rec-ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reachthe recommended amount.
If you overfill the tyre, release air by pushing on the metal stem in the
centre of the tyre valve. Recheck the
tyre pressure with the tyre gauge. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture. Tyre rotation
To equalize tread wear, it is recom- mended that the tyres be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of tyre. Replace the tyre if you find
either of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring thefront and rear tyre pressures to spec-
ification and check nut tightness.
WARNING
Inspect your tyres frequently for proper inflation as well as
wear and damage. Always use
a tyre pressure gauge.
Tyres with too much or too lit- tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and suddentyre failure leading to acci-
dents, injuries, and even death.The recommended cold tyre
pressure for your vehicle can
be found in this manual and onthe tyre label located on the
driver's side centre pillar.
Worn tyres can cause acci- dents. Replace tyres that are
worn, show uneven wear, or
are damaged.
Remember to check the pres- sure of your spare tyre.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tyres on your
vehicle.

4. Tyre ply composition and material
The number of layers or plies of rub-
ber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, 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 theletter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflation
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 ofthe 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 graded100.
The relative performance of tyres depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle
tyres. The tyres available as standard
or optional equipment on your vehi-
cle may vary with respect to grade.

Maintenance
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any acid detergent. It may damage and corrode the aluminum
wheels coated with a clear protectivefinish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we 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 isalso required.
Common causes of corrosion The most common causes of corrosion
on your car are:
allowed to accumulate underneath the
car.
Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion. High-corrosion areas
If you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly impor-
tant. Some of the common causes of
accelerated corrosion 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, particularly when tempera-
tures are just above freezing. In such
conditions, the corrosive material is kept
in contact with the car surfaces by mois-
ture 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 themoisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dis-
persed. For all these reasons, it is par-
ticularly 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.
