Filter inspection
If the vehicle is operated in the
severely air-polluted cities or on
dusty rough roads for a long period,
it should be inspected more fre-
quently and replaced earlier. When
you, the owner, replace the climate
control air filter, replace it performing
the following procedure, and be care-
ful to avoid damaging other compo-
nents.
Replace the filter according to the
maintenance Schedule.
Filter replacement
1. Open the glove box and remove
the support strap (1).
CAUTION - Air filter
maintenance
Do not drive with the air clean-er removed; this will result inexcessive engine wear.

WIPER BLADES
Blade inspection
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean. Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours. When recharging the battery, observe
the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Watch the battery during charging, and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 120°F (49°C).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
Before performing maintenance or recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last
when the battery is disconnected.

Maintenance
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
1 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. Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear at the center of the
tire tread, and a greater possibility
of damage from road hazards.
Warm tires normally exceed rec- ommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.OHG050081L
WARNING - Tire under
inflation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
can lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control leading to severe injury
or death. This risk is much high-
er on hot days and when driving
for long periods at high speeds.

Always observe the following:
Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
has not been driven more than 1
mile (1.6 km) since startup.)
Check the pressure of your spare tire each time you check the pres-
sure of other tires.
Never overload your vehicle. Be careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Worn, old tires can cause acci- dents. If your tread is badly worn,
or if your tires have been dam-
aged, replace them.
Checking tire inflation pressure
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). 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.
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.

739
Maintenance
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.
Refer to “Tire and wheels” in section 8.

■Without a spare tire
■ Directional tires (if equipped)WARNING
Inspect your tires frequently
for 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.
