4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric 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 amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire 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 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:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
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
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.

Maintenance
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grade C
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference between
the lamp inside and the outside tem-
perature. This is similar to the conden-
sation on your windows inside your
vehicle during the rain and doesn’t
indicate a problem with your vehicle.
If the water leaks into the lamp bulb
circuitry, have your vehicle checked by
an authorized HYUNDAI dealer.
i
Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the igntion switch to the
LOCK/OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

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 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 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
Keep your car 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.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust Emission Control System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Vehicle modifications
This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

Specifications, Consumer information and Reporting safety defects
Recommended SAE viscosity
number
Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage.Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.
