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 maintenance
schedule.
Reduction Gear Fluid
The reduction gear fluid should be
inspected according to the intervals
specified in the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the 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 conforming to DOT
4 specification.
Brake Discs, Pads, Calipers and
Rotors
Check the pads, the disc, and the rotor
for any excessive wear-out. Inspect
calipers for any 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

Maintenance
„Standard coolant
ORG3EV091003
„Low conductivity coolant
ORG3EV091002
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 or F and the MIN
or L marks on the side of the coolant
reservoir when the parts in the motor
compartment is cool.
If the coolant is low, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
Use only designated coolant for electric
vehicles, adding other types of water or
antifreeze can damage the vehicle.
WARNING
Since specific coolant (Blue color, Low
conductivity) is applied for electric
vehicles, replenishment of other
antifreeze or water may cause problems
to the vehicle.
WARNING
The electric motor for the
cooling fan may continue to
operate or start up when the
vehicle is not running and can
cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
The electric motor for the cooling
fan is controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off. This is
a normal condition.

WARNING

[Check the coolant level when
the motor compartment
is cooled. Coolant level is
influenced by temperature,
and if the coolant reservoir
cap is removed when coolant
temperature is high, hot
coolant and steam may blow
out under pressure causing
serious injury.

[Make sure the coolant cap is properly
closed after refilling coolant.
Otherwise the motor could be
overheated while driving.

1. Check if the coolant cap label is
straight in front.

2. Make sure that the tiny protrusions
inside the coolant cap are securely
interlocked.

Maintenance
Checking the Brake Fluid Level
ORG3EV091004
Check the fluid level in the reservoir
periodically. 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 the specified brake
fluid to the MAX level. The level will fall
with accumulated kilometers. This is a
normal condition associated with the
wear of the brake linings. If the fluid level
is excessively low, have the brake system
checked by an authorized retailer of
Genesis Branded products.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. Have the
vehicle inspected by an authorized
retailer of Genesis Branded products.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE

[Do not allow brake fluid to contact
the vehicle’s body paint, as it will
result in paint damage.

[NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed. It should be disposed
of properly.

[Do not use the wrong type of brake
fluid. A few drops of mineral based
oil in your brake system can damage
brake system parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).

Checking the Washer Fluid Level
ORG3EV091005
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 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.
WASHER FLUID REDUCTION GEAR FLUID
There is no reduction gear fluid level
gauge in the vehicle. Check the
reduction gear fluid every 60,000 km
regularly. If the vehicle is driven under
severe condition, check the maintenance
under severe usage condition and
consult an authorized retailer of Genesis
Branded products.

Maintenance
Blade Inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not:

[Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.

[Attempt to move the wipers
manually.

[Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Information
Wiper blades are consumable items.
Normal wear of the wipers may not be
covered by your vehicle warranty.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE

[In order to prevent damage to the
hood and the wiper arms, the wiper
arms should only be lifted when in
the top wiping position.

[Always return the wiper arms to the
windshield before driving.

ORG3EV091050N
1. Within 20 seconds of turning off the
vehicle, lift up and hold the wiper
lever to the MIST position for about 2
seconds until the wipers move to the
top wipe position.
2. At this time you can lift the wipers off
the windshield.
Information
This vehicle has a “hidden” wiper design
which means that the wipers cannot be
lifted manually when they are in their
bottom resting position.
