Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
• When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.

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.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 pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
• Check the pressure of the
spare (if equipped) every time
you check the pressure of the
other tires on your vehicle.
(Continued)
(Continued)
• Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, 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 recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.

All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar
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).
Warm tires normally exceed recom-
mended cold tire pressures 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-inflat-
ed. For recommended inflation pres-
sure, refer to “Tire and Wheels” in
chapter 8.
OMD060012N
WARNING
Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.

Maintenance
Check tire inflation pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge 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 pressure. Make sure to
put the valve caps back on the valve
stems. 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.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 gauge. Be
sure to put the valve caps back on
the valve stems. 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.
CAUTION
Under-inflation results in exces-
sive wear, poor handling and
reduced fuel economy. Wheel
deformation is also possible.
Keep your tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked
by an authorized HYUNDAI deal-
er.
Over-inflation produces a harsh
ride, excessive wear at the cen-
ter of the tire tread, and a
greater possibility of damage
from road hazards.

Maintenance
44 7
Tire rotation
To equalize tread wear, HYUNDAI
recommends 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 (proper torque is
9-11 kg.m [65-79 lb.ft]).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.
OBH078040 ■Without a spare tire
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 may cause loss of
vehicle control resulting in an
accident.
