Maintenance
The 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.
Changing Engine Coolant
Have coolant changed by an author-
ized retailer of Genesis Branded
products according to the
Maintenance Schedule at the begin-
ning 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 generator.
NOTICE
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause seri-
ous injury. Keep
hands, clothing and tools away
from the rotating fan blades of
the cooling fan.
WARNINGDo 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.
WARNING
(Continued)
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning
counterclockwise to remove it.

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.
OHI076017
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 wind-
shield 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 flamma-
ble.
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.

dusty or sandy areas, replace the ele-
ment more often than the usual rec-
ommended intervals (refer to

does not enter the air intake, or
damage may result.
Use Genesis/Hyundai Part, use of non-Genesis/Hyundai Part

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes dischargedin a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.
AGM battery
Absorbent Glass Matt (AGM) batteries are maintenance-free
and we recommend that the
AGM battery be serviced by an
authorized retailer of Genesis
Branded products. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
When replacing the AGM bat- tery, we recommend that you
use parts for replacement from
an authorized retailer of Genesis
Branded products.
Do not open or remove the cap on top of the battery. This may
cause leaks of internal elec-
trolyte that could result in
severe injury.
NOTICE
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
Before performing mainte-nance or recharging the bat-
tery, turn off all accessories
and press the Engine Start/
Stop button to the OFF posi-
tion.
Keep all flames, sparks, or smoking materials away from
the battery.
Always work outdoors or in an area with plenty of ventilation.
Wear eye protection when checking the battery during
charging.
The battery must be removed from the vehicle and placed in
a well ventilated area.
