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 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.

„„Standard coolant
ONE1091002
„„Low conductivity coolant
ONE1091003
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 HYUNDAI
dealer.
Use only designated coolant water for
electric vehicles, adding other types
of water or antifreeze can damage the
vehicle.
WARNING
Since specific coolant water (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.

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.

WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns: • Before performing maintenance or
recharging the battery, turn off all
accessories and stop the vehicle.
• 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.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin boiling
violently.
• The negative battery cable must
be removed first and installed last
when the battery is disconnected.
Disconnect the battery charger in the
following order:
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
• Use batteries for replacement from
an authorized HYUNDAI dealer. By jump starting
After a jump start from a good battery,
drive the vehicle for 20-30 minutes
before it is shutoff. The vehicle may
not restart if you shut it off before the
battery had a chance to adequately
recharge. See “Jump Starting” in chapter
8 for more information on jump starting
procedures.
Information
An inappropriately disposed battery can be harmful to the
environment and human health. Dispose of the battery according
to your local law(s) or regulation.
Reset Items
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected. •

WARNING
Tire failure may cause loss of vehicle
control resulting in an accident. To
reduce risk of SERIOUS INJURY or
DEATH, take the following precautions: • Inspect your tires monthly for proper
inflation as well as wear and damage.
• The recommended cold tire pressure
for your vehicle can be found in this
manual and on the tire label located
on the driver’s side center pillar.
Always use a tire pressure gauge to
measure tire pressure. Tires with
too much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the spare
every time you check the pressure of
the other tires on your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, or
traction.
• ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that was
originally supplied with this vehicle.
Using tires and wheels other than
the recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively
affect your vehicle’s Anti-Lock Brake
System (ABS) resulting in a serious
accident.Tire Care
For proper maintenance, safety, and
maximum electric energy economy, you
must always maintain recommended
tire inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
OJK010021
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the spare)
should be checked when the tires are
cold. “Cold tires” means the vehicle has
not been driven for at least three hours
or driven less than one mile (1.6 km).
Warm tires normally exceed
recommended cold tire pressures by 28
to 41 kPa (4 to 6 psi). Do not release air
from warm tires to adjust the pressure
or the tires will be under-inflated. For
recommended inflation pressure, refer to
“Tire and Wheels” section in chapter 2.
