Recommended engine coolant
When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
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 mixture percentage, refer to the fol-
lowing table. Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
WARNING
Radiator cap
Do not remove the radiator cap when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
CAUTION
Put a thick cloth around the radiator cap before refilling the coolant in order to prevent the coolant fromoverflowing into engine parts such
as the generator.
WARNING - 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.

BRAKE AND CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. 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 normal condition asso-
ciated 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.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants orcapacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor as soon as possible.
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
OBK079007
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, aspaint damage will result.
Brake/clutch fluid, which has beenexposed to open air for an extended time should never be used as itsquality cannot 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 damage brake /clutch system parts.

POWER STEERING FLUID
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the gauge at the normal tempera-
ture.
Before adding power steering fluid, thor- oughly clean the area around the reser-
voir cap to prevent power steering fluidcontamination.
If the level is low, add fluid to the MAX
level.
✽✽ NOTICE - (if equipped)
Check that the fluid level is in the "HOT" range on the gauge. If the fluidis cold, check that it is in the "COLD"range.
In the event the power steering system
requires frequent additions of fluid, werecommend that the system be inspect-
ed by an authorized HYUNDAI dealer.
Use only the specified power steering fluid. (Refer to "Recommended lubricants
or capacities" in section 8.)
Checking the power steering hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering pump, do not operate the
vehicle for prolonged periods with a low power steering fluidlevel.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering
system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visualinspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. 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’’ heardwhile fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be serviced by an authorized
HYUNDAI dealer.
Stroke : 5 notch at a force of 20 kg
(44 lbs, 196 N).
WARNING - 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.
Windshield Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.
