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 the engine
off, check for excessive freeplay in the
steering wheel. Check the linkage for
bends or damage. 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
Check the air conditioning lines and
connections for leakage and damage.

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
type, size, brand, construction and
tread pattern 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 fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.
ODN8H019025L
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 one mile
(1.6 km).
Warm tires normally exceed
recommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pressure
or the tires will be under-inflated. For
recommended inflation pressure, refer to
“Tire and Wheels” in chapter 2.

Tire Replacement
Tread wear indicatorTread wear indicator
OLMB073027
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 (2/32 inch) of tread left
on the tire. Replace the tire when this happens.
Do not wait for the tread surface to
become level with the tread wear
indicators 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. •
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.
• When replacing tires, it is
recommended to replace the two
front or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling. If
only replacing one pair of tires, it is
recommended to install the pair of
new tires on the rear axle.
• 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.
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the tread
wear indicator bars on the tire. The
replacement compact spare tire should
be the same size and design tire as the
one provided with your new vehicle
and should be mounted on the same
compact spare tire wheel. The compact
spare tire is not designed to be mounted
on a regular size wheel, and the compact
spare tire wheel is not designed for
mounting a regular size tire.
WARNING
The original tire should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tire is for emergency
use only. Do not operate your vehicle
over 80 km/h (50 mph) when using the
compact spare tire.

Maintenance

•
When cleaning underneath the
vehicle, pay particular attention to the
components under the fenders and
other areas that are hidden from view.
Do a thorough job; just dampening
the accumulated mud rather than
washing it away will accelerate
corrosion rather than prevent it. Water
under high pressure and steam are
particularly effective in removing
accumulated mud and corrosive
materials.
• When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.
Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This creates
a favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered with
snow, ice or mud. Even a heated garage
can contribute to corrosion unless it is
well ventilated so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish should
be covered with “touch-up” paint as
soon as possible to reduce the possibility
of corrosion. If bare metal is showing
through, the attention of a qualified body
and paint shop is recommended.
Bird droppings are highly corrosive and
may damage painted surfaces in just a
few hours. Always remove bird droppings as soon as possible.
Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from
contacting the interior parts because
they may cause damage or discoloration.
If they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to clean
vinyl.
NOTICE
• Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
• When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or acid/
alkaline detergents, the color of the
leather may fade or the surface may
get stripped off.
Cleaning the upholstery and interior trim
Vinyl (if equipped)
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl surfaces with a vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from
fabric with a whisk broom or vacuum
cleaner. Clean with a mild soap solution
recommended for upholstery or carpets.
Remove fresh spots immediately with
a fabric spot cleaner. If fresh spots do
not receive immediate attention, the
fabric can be stained and its color can be
affected. Also, its fire-resistant properties
can be reduced if the material is not
properly maintained.
