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 at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.

Checking the coolant level
ENGINE COOLANT
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.
Turn the engine off and wait until it
cools 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.
(Continued)
(Continued)
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. If your
vehicle is equipped with GDI, the
electric motor (cooling fan) may
operate until you disconnect the
negative battery cable.

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. Bring the level
to F, but do not overfill. If frequent addi-
tions are required, see an authorized
HYUNDAI dealer for a cooling system
inspection.
G070101AUN
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 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.

BRAKE FLUID
G080100AEN
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.
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. (Refer
to “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 contact
the vehicle's body paint, as paint
damage will result. Brake 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 disposed
of 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 damage
brake system parts.

POWER STEERING FLUID
G090100ABH
Checking the power steering fluid
level
With the vehicle on level ground, check the
fluid level in the power steering reservoir
periodically. The fluid should be between
MAX and MIN marks on the side of the
gauge at the normal temperature.
Before adding power steering fluid, thor-
oughly clean the area around the reservoir
cap to prevent power steering fluid contam-
ination.
If the level is low, add fluid to the MAX level.
In the event the power steering system
requires frequent addition of fluid, the vehi-
cle should be inspected by an authorized
HYUNDAI dealer.
Use only the specified power steeringfluid. (Refer to "Recommended lubricantsor capacities" in section 8.)
G090200AEN
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 thevehicle for prolonged periods witha low power steering fluid level.
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 steeringsystem.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.
