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:
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 temperature ranges of
- 31°F and higher.

MaintenanceThe 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.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.
WARNING
Never remove the
engine coolant reser-
voir tank/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.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/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.

Changing Engine Coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this chapter.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 alternator.
NOTICE

Maintenance
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 accident.
Engine coolant may also cause
damage to paint and body trim.

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 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/clutch linings. If the fluid level
is excessively low, have the brake/
clutch system checked by an author-
ized HYUNDAI dealer.
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.
Information
Use only the specified brake/clutch
fluid (refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).
i
NOTICE
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.

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 44

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
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 accident or dam-
age to paint and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain alco-
hol and can be flammable.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful to
humans and animals.
Keep washer fluid away from
children and animals.

Maintenance
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual rec-
ommended intervals (refer to
"Maintenance Under Severe Usage
Conditions" in this chapter).
Do not drive with the air cleanerfilter removed. This will result in
excessive engine wear.
When removing the air cleaner filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use HYUNDAI genuine parts. Use of non-genuine parts could
damage the air flow sensor.
Filter Inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, removethe stoppers on both sides to allow
the glove box to hang freely on the
hinges.
