Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Please remember some driving con-
ditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.

Maintenance
Brake pads, calipers and
rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more infor mation on checking
the pads or lining wear limit, refer to
the HYUNDAI web site.
(http://brakemanual.hmc.co.kr)
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant/
compressor
Check the air conditioning lines and
connections for leakage and dam-
age.

Maintenance
Tire rotation
To equalize tread wear, it is recom-
mended that the tires be rotated
ever y 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.
Refer to “Tire and wheels” in section
8.
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The outside and inside of the
unsymmetrical tire is distinguish-
able. When installing an unsym-
metrical tire, be sure to install the
side marked "outside" face the
outside. If the side marked
"inside" is installed on the out-
side, it will have a bad effect on
vehicle performance.
i
•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 unusu-
al handling characteristics that
could result in death, severe
injury, or property damage.
