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.
Tire replacement
Tread wear indicatorTread wear indicator
OHI078080
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 1/16 in. (1.6 mm) 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
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and 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.
• When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.
• Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six (6)
years of normal service.
• Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

Low aspect ratio tires
(if equipped)
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
The side wall of a low aspect ratio
tire is shorter than the normal one.
Thus, the low-aspect wheel and
tire are easily damaged. Follow the
below instructions.
• When driving on a rough road or
driving off a road, be careful not
to damage the tires and wheels.
After driving, inspect the tires
and wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tires and
wheels.
• When there is an impact on a tire,
inspect the tire condition. Or,
you can contact an authorized
HYUNDAI dealer.
• Inspect the tire condition and
pressure every 1,800 miles (3,000
km) to prevent tire damage.
• It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.
• When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such as a
pothole, manhole, or curb stone,
your warranty does not cover the
damage.
• The tire information is specified
on the tire side wall.

Maintenance

Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
NOTICE
• Do not use abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels.
• Clean the wheel when it has cooled.
• Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, clean the wheels after
driving on salted roads.
• Do not wash the wheels with high-
speed car wash brushes.
• Do not use any cleaners containing
acid or alkaline detergents.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI produces vehicles
of the highest quality. However, this is
only part of the job. To achieve the long-
term corrosion resistance your vehicle
can deliver, the owner’s cooperation and
assistance is also required.
Common causes of corrosion
The most common causes of corrosion
on your vehicle are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
• Removal of paint or protective
coatings by stones, gravel, abrasion
or minor scrapes and dents which
leave unprotected metal exposed to
corrosion. High-corrosion areas
If you live in an area where your vehicle is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to occur.
For example, corrosion is accelerated
by high humidity, particularly when
temperatures are just above freezing. In
such conditions, the corrosive material is
kept in contact with the vehicle surfaces
by moisture that is slow to evaporate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still retain
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly important to keep your
vehicle clean and free of mud or
accumulations of other materials. This
applies not only to the visible surfaces
but particularly to the underside of the
vehicle.
