ENGINE COOLANT/LIQUID-COOLED INTERCOOLER 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 climate.

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 MAX and the MIN 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 MAX mark, but do not overfill.
If frequent additions are required, see an
authorized retailer of Genesis Branded
products for a cooling system inspection.

WARNING
Never remove the engine coolant radiator cap, coolant
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 vehicle off and wait until
the engine cools down. Use extreme
care when removing the radiator cap,
coolant 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 counterclockwise to
remove it.
Information
The coolant level is influenced by the
engine temperature. Before checking or
refilling the coolant, turn the engine off.
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.
Always turn off the vehicle unless the
vehicle has to be inspected with the
engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

WASHER FLUID
Checking the Washer Fluid Level
ORG3090013
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
climates to prevent freezing.
WARNING
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 damage to
paint and body trim.
• Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol 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.
