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
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
CAUTION
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manual-
ly.
CAUTION
The use of a non-specified wiper
blade could result in wiper malfunc-
tion and failure.

For best battery service
• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connections
clean, tight, and coated with petroleum
jelly or terminal grease.
• Rinse any spilled electrolyte from the
battery immediately with a solution of
water and baking soda.
• If the vehicle is not going to be used for
an extended time, disconnect the bat-
tery cables.
✽NOTICE
Basically equipped battery is mainte-
nance free type. If your vehicle is
equipped with the battery marked with
LOWER and UPPER on the side, you can
check the electrolyte level. The electrolyte
level should be between LOWER and
UPPER. If the electrolyte level is low, it
needs to add distilled (demineralized)
water (Never add sulfuric acid or other
electrolyte). When refill, be careful not to
splash the battery and adjacent compo-
nents. And do not overfill the battery
cells. It can cause corrosion on other
parts. After then ensure that tighten the
cell caps. We recommend that you contact

Maintenance
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
have it checked by an author-
ized HYUNDAI dealer.
• Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread, and
a 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 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
1.6 km (one mile).
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 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 1.6 km (1 mile).
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 vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km (one
mile) since startup.)
• Check the pressure of your
spare tire each time you check
the pressure 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 damaged, replace them.
CAUTION
• Warm tires normally exceed
recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
• 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.

745
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 12,000 km (7,500 miles) 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 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 vehi-
cle.

Maintenance
46 7
Disc brake pads should be inspected
for wear whenever tires are rotated.
✽NOTICE
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
Wheel alignment and tire balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.

Directional tires (if equipped)WARNING
• Do not use the compact spare
tire for tire rotation.
• Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.
CAUTION
Improper wheel weights can
damage your vehicle's alu-
minum wheels. Use only
approved wheel weights.

747
Maintenance
Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.

WARNING - Replacing
tires
• Driving on worn-out tires is very
hazardous and will reduce brak-
ing effectiveness, steering
accuracy, and traction.
• Your vehicle is equipped with
tires designed to provide for
safe ride and handling capabili-
ty. Do not use a size and type of
tire and wheel that is different
from the one that is originally
installed on your vehicle.
(Continued)
CAUTION
When replacing the tires,
recheck and tighten the wheel
nuts after driving about 1,000
km (620 miles). If the steering
wheel shakes or the vehicle
vibrates while driving, the tire is
out of balance. Align the tire bal-
ance. If the problem is not
solved, we recommend that you
contact an authorized HYUNDAI
dealer.
(Continued)
It can affect the safety and per-
formance of your vehicle, which
could lead to handling failure or
rollover and serious injury.
When replacing the tires, be
sure to equip all four tires with
the tire and wheel of the same
size, type, tread, brand and load-
carrying capacity.
• The use of any other tire size or
type may seriously affect ride,
handling, ground clearance,
stopping distance, body to tire
clearance, snow tire clearance,
and speedometer reliability.
• It is best to replace all four tires
at the same time. If that is not
possible, or necessary, then
replace the two front or two rear
tires as a pair. Replacing just
one tire can seriously affect
your vehicle’s handling.
