WARNING
To prevent serious or fatal injury:

[Do not get out of the vehicle without
the parking brake firmly set. If you
have left the vehicle running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.

[Do not apply the accelerator pedal to
hold the vehicle on an uphill.
Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:

[Start your vehicle;

[Shift into gear; and

[Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when Towing a
Trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include reduction gear fluid,
axle lubricant and cooling system fluid.
Brake condition is another important
item to frequently check. If you’re
trailering, it’s a good idea to review these
items before you start your trip. Don’t
forget to also maintain your trailer and
hitch. Follow the maintenance schedule
that accompanied your trailer and check
it periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:

[Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.

[When towing check reduction gear
fluid more frequently.

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.
Replace any damaged parts and, if
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and 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.
