Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction Gear Fluid
Inspect the reduction gear fluid
according to the maintenance sched-
ule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake Fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 4 specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the
vehicle off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

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 parts in the motor
compartment is cool.
If the coolant level is low, have your
vehicle inspected by an authorized
HYUNDAI dealer. Use only designat-
ed coolant water for electric vehicles,
adding other types of water or
antifreeze can damage the vehicle.The electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
OAEE076002L
Since a specific coolant water is
applied for electric vehicles,
replenishment of other
antifreeze or water may cause
problems to the vehicle.
WARNING
The electric motor for the cool-
ing fan may continue to operate
or start up when the vehicle is
not running and can cause seri-
ous injury. Keep hands, clothing
and tools away from the rotat-
ing fan blades of the cooling
fan.

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.
OAEE076004
To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use coolant or
antifreeze in the washer fluid
reservoir.
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.

Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.
Intended Outboard Sidewall
The side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light truck(LT) tire
A tire designated by its manufacturer
as primarily intended for use on light-
weight trucks or multipurpose pas-
senger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.

This is primarily due to reduced per-
formance of the EV battery when
exposed to cold temperatures.
Some vehicles may come equipped
with Winter mode selectable option.
The Winter mode feature can be
selected in the EV Settings menu.
When selected, Winter mode
enables the use of the EV battery
coolant heater. This mode is recom-
mended to improve EV battery per-
formance in cold climate conditions.
Note that EV range may reduce
when Winter mode is enabled, as
electrical energy is used to maintain
the EV battery temperature.
Winter mode enables operation of
the EV battery coolant heater. While
driving your vehicle, if the battery
temperature is low or the A/C and/or
heater is turned ON, the EV battery
coolant heater will be used.
Note that the EV battery coolant
heater will not be used when the EV
battery SOC is low.
❈This mode is available for the vehi-
cles equipped with the battery
heater.Warning
You can select or deselect the Range
Warning.
- Range Warning: If the destination
set in the navigation cannot be
reached with the remaining EV bat-
tery charge level, a warning mes-
sage is displayed.
EV route
If EV route is selected, EV related
information will show on the route.
You can check the distance the vehi-
cle can be driven with the current EV
battery charge level % along the
route.
An icon is also indicated so the driv-
er is able to search for nearby charg-
ing stations.
