ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.Checking the engine coolant
level
WARNING
Never remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
(Continued)
OMD070005N-1
(Continued)
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
WARNING
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.

727
Maintenance
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.
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 the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring
the level to the F mark, but do not
overfill. If frequent additions are
required, we recommend that you
see an authorized HYUNDAI dealer
for a cooling system inspection.Recommended engine coolant
• When adding coolant, use only
deionized water, distilled water or
soft water for your vehicle and
never mix hard water in the coolant
filled at the factory.
• An improper coolant mixture can
result in severe 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.

For mixing percentage, refer to the
following table:
✽NOTICE
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 tempera-
ture ranges of -31°F and higher.
Changing engine coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this chapter.CAUTION
To prevent damage to engine
parts, put a thick towel around
the radiator cap before refilling
the coolant to prevent the
coolant from overflowing into
engine parts, such as the gener-
ator.
WARNING
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
• Engine coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control resulting in an acci-
dent.
• Engine coolant may also
cause damage to paint and
body trim.

BRAKE/CLUTCH FLUID
Checking the brake/clutchfluid
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 the specified
brake/clutch fluid to the MAX level.
The level will fall with accumulated
mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake/clutch system checked by
an authorized HYUNDAI dealer.
✽NOTICE
Use only the specified brake/clutch
fluid (refer to “Recommended
Lubricants and Capacities” in chap-
ter 8).
WARNING
If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. Have
the vehicle inspected by an
authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention.
CAUTION
• 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 cannot be
guaranteed. It should be dis-
posed of properly.
• Do not use the wrong kind of
brake/clutch fluid. A few drops
of mineral based oil, such as
engine oil, in your brake/
clutch system can damage
brake/clutch system parts.

WASHER FLUID
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 6 clicks at a force of 20 kg
(44 lbs, 196 N)
