COOLANT
Inverter coolant
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level everyday. If it is near or at MIN, add enough coolant
between MIN and MAX and check the
cooling system for air bleed at an author-
ized HYUNDAI dealer.
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 per every day, at the begin-
ning of the winter season, and before
traveling to a colder climate.
Checking the coolant level
CAUTION
Do not confuse the cap of engine
coolant and inverter coolant. If not, the coolant circulation problem ofengine or Hybrid system may occur because the cap pressure is different.
CAUTION
When adding coolant, be carefulnot to overfill.
WARNING
Removing radiator
cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
The engine coolant level is influ- enced by hybrid system tempera-
ture. Before filling the engine
coolant, turn the hybrid vehicle off,
fill the engine coolant carefully.

Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and 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 provide pro-
tection against freezing and corrosion.
Bring the level to F, but do not overfill. If
frequent additions are required, see an
authorized HYUNDAI dealer for a cooling
system inspection.

(Continued)
Turn the engine off and wait until itcools down. Use extreme care
when removing 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 cool-
ing system. When you are sure all
the pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
Even if the engine is not operat- ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.WARNING
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 tem-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition.

Recommended engine and inverter
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 aluminum engine parts and must be protected by
an ethylene-glycol-based coolant to pre-
vent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the specified
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 mixture percentage, refer to the fol-
lowing table.
Changing the coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
WARNING - Radiator cap &
Inverter coolant cap
Do not remove the radiator cap and
inverter coolant cap when the
engine and radiator are hot.
Scalding hot coolant and steam
may blow out under pressure caus-
ing serious injury.
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.
CAUTION
Put a thick cloth or fabric aroundthe radiator cap before refilling thecoolant in order to prevent thecoolant from overflowing intoengine parts such as generator.

BRAKE FLUID
Checking the brake 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. To check the brake
fluid exactly, after stopping the vehicle,
apply the brake pedal few times and then
check the fluid level.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake 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, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid. (Referto “Recommended lubricants or capaci-ties” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake 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 doctor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
CAUTION
Do not allow brake fluid to contactthe vehicle's body paint, as paint damage will result. Brake fluid,which has been exposed to open air for an extended time should neverbe used as its quality cannot be guaranteed. It should be disposedof properly. Don't put in the wrong kind of fluid. A few drops of miner-al-based oil, such as engine oil, in your brake system can damagebrake system parts.
CAUTION
If the brake fluid is overfilled than MAX, the other parts may be dam-aged while depressing the brake pedal repeatedly or driving thevehicle because the fluid flows, donot overfill.

WASHER FLUID
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
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 whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 44 lb (20 kg, 196 N) of
force. 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 : 4~5 notch
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 allow
sparks or flame to contact the
washer 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.
