If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals. (Refer to “Maintenance under severe usage condi-tions” in this section.)
CAUTION
Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, ordamage may result.
Use a Hyundai genuine part. Use of nongenuine parts could dam-age the air flow sensor.

CLIMATE CONTROL AIR FILTER
Filter inspection
The climate control air filter should be
replaced every 10,000 miles (15,000
km). 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 frequently and
replaced earlier. When you, the owner,
replace the climate control air filter,
replace it performing the following proce-
dure, and be careful to avoid damaging
other components.
Filter replacement
1. Open the glove box and remove thesupport rod. 2. With the glove box open, remove the

WIPER BLADES
Blade inspection
✽
✽NOTICE
Commercial hot waxes applied by auto-
matic car washes have been known to
make the windshield difficult to clean.
Contamination of either the windshield or
the wiper blades with foreign matter can
reduce the effectiveness of the wind-
shield wipers. Common sources of con-
tamination are insects, tree sap, and hot
wax treatments used by some commer-
cial car washes. If the blades are not wip-
ing properly, clean both the window and
the blades with a good cleaner or mild
detergent, and rinse thoroughly with
clean water.Blade replacement
When the wipers no longer clean ade-
quately, the blades may be worn or
cracked, and require replacement.

1JBA5122CAUTION

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, 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.
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.

When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cables
are connected.
The electrical ignition system works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.

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 inflation
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. All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Severe underinflation (10 psi
(70 kPa) or more) 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.

OHD086003
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check tires are
properly inflated before driv-
ing.
Driving on tires with no or insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, and injury and even
death. Worn-out tires should
be replaced as soon as possi-
ble and should never be used
for driving. Always check tire
tread before driving your car.

Maintenance
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
Underinflation also results in excessive 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.
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.
