BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination.
If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings.
If the fluid level is excessively low, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.
Information
Use only the specified brake/clutch
fluid. (Refer to “Recommended
lubricants and capacities” in sec-
tion 8.)
Never mix different types of fluid.
Before removing the brake/clutch
filler cap, read the warning on the
cap.
NOTICE
i
OLF074008
In the event the brake/clutch
system requires frequent addi-
tions of fluid, we recommend
that the system be inspected by
an authorized HYUNDAI dealer.
WARNING
Clean filler cap before remov-
ing. Use only DOT3 or DOT4
brake/clutch fluid from a sealed
container.
WARNING

7-34
Maintenance
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If brake/
clutch fluid should come in con-
tact with your eyes, immediately
flush them with a large quantity
of fresh tap water. Have your
eyes examined by a doctor as
soon as possible.
WARNING
Do not allow brake/clutch fluid
to contact the vehicle's body
paint, as paint damage will
result. Brake/clutch fluid, which
has been exposed to open air
for an extended time should
never be used as its quality can-
not be guaranteed. It should be
disposed of properly. Don't put
in the wrong kind of fluid.
A few drops of mineral-based
oil, such as engine oil, in your
brake/clutch system can dam-
age brake/clutch system parts.

•Keep the battery top clean and dry.
•Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
•Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
•If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.
Information
Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.
After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.

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.
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 (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section 8.
All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
Tire underinflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.
WARNING
OLF084007N

Maintenance
•Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
•Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread,
and a greater possibility of
damage from road hazards.
CAUTION
•Warm tires normally exceed
recommended cold tire pres-
sures 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-
inflated.
•Be sure to reinstall the tire
inflation valve caps. 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
Tire pressure
Always observe the following:
•Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been driv-
en more than 1.6 km (1 mile)
since startup.)
•Check the pressure of your
spare tire each time you check
the pressure of other tires.
•Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
•Wo r n , o l d t i r e s c a n c a u s e
accidents. If your tread is
badly worn, or if your tires
have been damaged, replace
them.
CAUTION
Tire inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
WARNING

7-48
Maintenance
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
Remove the valve cap from the tire
valve stem. Press the tire gage 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 amount.
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 gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.
•Inspect your tires frequently
for proper inflation as well as
wear and damage. Always use
a tire pressure gauge.
•Tires with too much or too little
pressure wear unevenly caus-
ing poor handling, loss of vehi-
cle control, and sudden tire
failure leading to accidents,
injuries, and even death. The
recommended cold tire pres-
sure for your vehicle can be
found in this manual and on
the tire label located on the dri-
ver's side center pillar.
•Wo r n t i r e s c a n c a u s e a c c i -
dents. Replace tires that are
worn, show uneven wear, or
are damaged.
•Remember to check the pres-
sure of your spare tire.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tires on your vehi-
cle.

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.

Maintenance
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factor y 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.
Improper wheel weights can
damage your vehicle's aluminum
wheels. Use only approved wheel
weights.
Tire replacement
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 (1/16 in.) 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 replac-
ing the tire.
NOTICE
OLMB073027
Tread wear indicatorWhen replacing the tires,
recheck and tighten the wheel
nuts after driving about 1,000
km (620 miles). If the steering
wheel shakes or the vehicle
vibrates while driving, the tire is
out of balance. Align the tire
balance. If the problem is not
solved, we recommend that you
contact an authorized HYUNDAI
dealer.
