Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not: • Use gasoline, kerosene, paint
thinner, or other solvents on or near them.
• Attempt to move the wipers
manually.
• Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to make the windshield difficult to clean.
Information
Wiper blades are a consumable item and
normal wear of the wipers may not be
covered by your vehicle warranty.
Blade replacement

Battery recharging
By battery charger
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.
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns: • Before performing maintenance or
recharging the battery, turn off all
accessories and place the START/
STOP button to the OFF position.
• Keep all flames, sparks, or smoking
materials away from the battery.
• Always work outdoors or in an area
with plenty of ventilation.

TIRE AND WHEELS
WARNING
Tire failure may cause loss of vehicle
control resulting in an accident. To
reduce risk of SERIOUS INJURY or
DEATH, take the following precautions: • Inspect your tires monthly for proper
inflation as well as wear and damage.
• 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 pillar.
Always use a tire pressure gauge to
measure tire pressure. Tires with
too much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the spare
every time you check the pressure of
the other tires on your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, or
traction.
• ALWAYS replace tires with the same
size as each tire that was originally
supplied with this vehicle. Using
tires and wheels other than the
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively
affect your vehicle’s Anti-Lock Brake
System (ABS) resulting in a serious
accident.Tire care
For proper maintenance, safety, and
maximum electric energy economy, you
must always maintain recommended
tire inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
OOS087003
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
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 has been driven for less than 1.6 km (1
mile).
Warm tires normally exceed
recommended cold tire pressures by 28
to 41 kpa (4 to 6 psi). Do not release air
from warm tires to adjust the pressure
or the tires will be under-inflated. For
recommended inflation pressure, refer to
“Tires and Wheels” in chapter 2.

Maintenance
9-22
Tire rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
every 10,000 km (6,000 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 pressure,
improper wheel alignment, out-of-
balance wheels, severe braking or severe
cornering. Look for bumps or bulges in
the tread or side of the tire. Replace the
tire if you find any 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 (proper
torque is 11~13 kgf·m [79~94 lbf·ft]).
„„Without a spare tire
ODH073802
Disc brake pads should be inspected for
wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguishable.
When installing an unsymmetrical tire, be
sure to install the side marked “outside” facing the outside. If the side marked “inside” is installed on the outside, it will have a negative effect on vehicle performance.
WARNING
• Do not use the compact spare tire for
tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause loss
of vehicle control resulting in an
accident.
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.
NOTICE
Incorrect wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.

Maintenance
9-24
Wheel replacement
When replacing the metal wheels for any
reason, make sure the new wheels are
equivalent to the original factory units in
diameter, rim width and offset.
Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. To reduce the
possibility of losing control, slow down
whenever there is rain, snow or ice on
the road.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly,
have your dealer check the wheel
alignment.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always
be rebalanced if it is removed from the wheel.
Tire sidewall labeling
This information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
