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.(Continued)

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
1.6 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 under-
inflation
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.
OBH088004N
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,
we recommend that the sys-
tem be 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.

Maintenance
40 7
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 1.6 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.

741
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 lit-
tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and sudden
tire failure leading to acci-
dents, injuries, and even
death. The recommended cold
tire pressure for your vehicle
can be found in this manual
and on the tire label located
on the driver's side center pil-
lar.
• 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
42 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 bal-
ance
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 vehi-
cle 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.
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
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
could result in death, severe
injury, or property damage.
CAUTION
Improper wheel weights can
damage your vehicle's aluminum
wheels. Use only approved wheel
weights.

Maintenance
WARNING- Replacing
tires
To reduce the chance or serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
• Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
• Do not drive your vehicle with
too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
• When replacing tires, never
mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.
(Continued)
(Continued)
• Using tires and wheel other
than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-
ous accident.
• Wheels that do not meet
HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
• The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) to work irregularly.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.
