While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check automatic transmission P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check the coolant level in theengine coolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air conditioning hoses for leaks or
damage.
Check the windshield washer spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.

Maintenance
CAUTION
Underinflation also results inexcessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section 8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1 mile (1.6 km).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
CAUTION- Tire pressure
Always observe the following: Check tire pressure when the tires are cold. (After vehiclehas been parked for at leastthree hours or hasn't beendriven more than one mile (1.6km) since startup.)
Check the pressure of your spare tire each time you checkthe pressure of other tires.
Never overload your vehicle. Be careful not to overload avehicle luggage rack if yourvehicle is equipped with one.
Worn, old tires can cause acci- dents. If your tread is badlyworn, or if your tires havebeen damaged, replace them.
CAUTION
Warm tires normally exceed recommended cold tire pres-sures by 4 to 6 psi (28 to 41kPa). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Be sure to reinstall the tire inflation valve caps. Withoutthe valve cap, dirt or moisturecould get into the valve coreand cause air leakage. If avalve cap is missing, install anew one as soon as possible.

Maintenance
Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.Tire rotation
To equalize tread wear, it is recom-
mended that the tires be rotated
every 7,500 miles (12,000 km) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.WARNING
Inspect your tires frequentlyfor proper inflation as well as
wear and damage. Always use
a tire pressure gauge.
Tires with too much or too little pressure wear unevenly caus-
ing poor handling, loss of vehi-
cle control, and sudden tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the tire label located on the dri-
ver's side center pillar.
Worn tires can cause acci- dents. Replace tires that are
worn, show uneven wear, or
are damaged.
Remember to check the pres- sure of your spare tire.
HYUNDAI recommends that
you check the spare every time
you check the pressure of the
other tires on your vehicle.

4. Tire ply composition and mate-rial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire manu-
facturers also must indicate the materi-
als in the tire, 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 inflationpressure
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.WARNING - Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury or
death.

Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical radial-ply tires should
always be used as a set of four.
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval shown in this section
to achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for sporty 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.
CAUTION
Because the sidewall of the low
aspect ratio tire is shorter thanthe normal, the wheel and tire ofthe low aspect ratio tire is easi-er to be damaged. So, follow theinstructions below.
- When driving on a rough road or off road, drive cautiouslybecause tires and wheels maybe damaged. And after driving,inspect tires and wheels.
- When passing over a pothole, speed bump, manhole, or curbstone, drive slowly so that thetires and wheels are not dam-aged.
(Continued)
CAUTION
It is not easy to recognize thetire damage with your owneyes. But if there is the slight-est hint of tire damage, eventhough you cannot see the tiredamage with your own eyes,have the tire checked orreplaced because the tiredamage 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 curbstone, it will not be covered bythe warranty.
You can find out the tire infor- mation on the tire sidewall.
(Continued)
- If the tire is impacted, we rec- ommend that you inspect thetire condition or contact anauthorized HYUNDAI dealer.
- To prevent damage to the tire, inspect the tire condition andpressure every 3,000miles.
