Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water.
Bring the level to F (MAX), but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer.
Recommended engine coolant
•When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
•The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
•DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified coolant.
•Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.

The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
WARNING

Maintenance
For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a
50% water and 50% antifreeze mix
is the easiest to mix together as it
will be the same quantity of each. It
is suitable to use for most temper-
ature ranges of -35°C (-31°F) and
higher.
Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.

Coolant
•Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
•Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.
WARNING
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as generator.

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.
CAUTION

BATTERY
For best battery service
•Keep the battery securely mounted.
•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.
i
Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.

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.
