THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
This hybrid vehicle uses the hybrid
battery system inverter and con-
verter to generate high voltage.
High voltage in the hybrid battery
system is very dangerous and can
cause severe burns and electric
shock. This may result in serious
injury or death.
For your safety, never touch,
replace, dismantle or remove the
hybrid battery system including
components, cables and connec-
tors. Severe burns or electric
shock may result in serious
injury or death if you do not fol-
low this warning.
When the hybrid battery system
operates, the hybrid battery sys-
tem can be hot. Always be care-
ful because burns or electric
shock maybe caused by high
voltage.
Do not drop water or liquid to
HPCU, HSG, Motor and fuses. The
hybrid system components are
covered, If you drop water or liq-
uid to hybrid system components,
it may result in electronic shock.
WARNING
This plug is attached to the hybrid
battery system, which contains
very dangerous high voltage.
Touching the service lever may
cause severe burns or electric
shock. When you touch it, be care-
ful not to damage.

The special features of hybrid
vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear a
sound. when you apply the brake pedal,
you may hear a sound from the regener-
ative brake system. When the hybrid sys-
tem is turned off or on, you may hear a
sound in the engine compartment. If you
depress the brake pedal repeatedly
when the hybrid system is turned on, you
may hear a sound in the engine com-
partment. None of these sounds indicate
a problem. They are characteristics of
hybrid vehicles.
If any of following occur, it's not a unnor-
mal condition even if you may hear a
motor sound in the engine compartment.
- After turning off the hybrid system, the
brake pedal is released.
- When the hybrid system is turned off,
the brake pedal is applied.
- When the driver door is opened.When the hybrid system is turned on, the
engine may run or not. In this situation,
you may feel a vibration. This does not
indicate a malfunction. If the "READY"
symbol is turned on, the hybrid system
starts. Even if the engine is off, you can
operate the vehicle.
WARNING
The hybrid system contains many
electronic components. High volt-
age components like cables and
other parts may emit electromag-
netic waves. Even if the electro-
magnetic cover blocks electromag-
netic emissions, electromagnetic
waves may have an effect on elec-
tronic appliances. If you park the
vehicle for a long time, the hybrid
system will discharge. You need to
drive the vehicle several times per
month. We recommend driving at
least 1 hour or 10 miles when you
drive the vehicle. If the hybrid bat-
tery is discharged and if it is impos-
sible to jump start the vehicle con-
tact your Hyundai dealer.
WARNING
When you start the hybrid system
in the "P" transmission position,
the "READY" symbol is illuminat-
ed in the cluster. The driver can
drive the vehicle even if the
engine is stopped.
When you leave the vehicle, you
should turn off the hybrid system
or shift into the "P" position. If
you depress the accelerator
pedal by mistake and the vehicle
is not in the "P" position, the
vehicle will move abruptly. This
may result in serious injury or
death.

H12
The hybrid battery air intake is located
behind the rear seats.The hybrid battery
air intake is used to cool the hybrid bat-
tery. If the hybrid battery air intake is
blocked, the hybrid battery may overheat.
Do not cover the air intake with objects.✽ ✽
NOTICE
Clean the air intake for the hybrid bat-
tery regularly with a dry cloth.
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
Never wash the intake of the
hybrid battery with a wet cloth. If
any water enters the air intake of
the hybrid battery, the hybrid bat-
tery may cause an electric shock.
The electric shock may cause seri-
ous damage, injury or death.
The hybrid battery is composed of
lithium-ion polymer. If you handle
a hybrid battery improperly, it is
dangerous to the environment and
may cause electrical shock and
severe burns. It may result in death
or serious injury.
Do not spill liquid over the air intake
of the hybrid battery. Doing so is
very dangerous and it may cause
electric shock or serious injury.
Do not cover the air intake with
objects.
Do not input any objects into the
air intake of the hybrid battery.
Doing so may cause loss of air
intake to the hybrid battery. If any
objects enters the air intake con-
tact your Hyundai dealer as soon
as possible.
(Continued)
(Continued)
Never place a container of liquid
on the air intake. If the liquid
spills, the hybrid battery located
in the trunk may be damaged.
While driving, be careful of mov-
ing loads in the trunk. Moving

(Continued)
(Continued)
Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to pre-
vent it from moving while driving.
Unsecured cargo in the passen-
ger compartment can cause dam-
age to the vehicle or injury to it’s
occupants.WARNING- Cargo
Cargo should always be secured to
prevent it from being thrown about
the vehicle in a collision and caus-
ing injury to the vehicle occupants.
Do not place objects on the rear
seats, since they cannot be proper-
ly secured and may hit the front
seat occupants in a collision.

Seat belt restraint system
SEAT BELTS
WARNING
Seat belts are designed to bear
upon the bony structure of the
body, and should be worn low
across the front of the pelvis, chest
and shoulders, as applicable; wear-
ing the lap section of the belt
across the abdominal area must be
avoided.
Seat belts should be adjusted as
firmly as possible, consistent with
comfort, to provide the protection
for which they have been designed.
A slack belt will greatly reduce the
protection afforded to the occu-
pant.
(Continued)
(Continued)
Care should be taken to avoid con-
tamination of the webbing with pol-
ishes, oils and chemicals and par-
ticularly battery acid. Cleaning may
safely be carried out using mild
soap and water. The belt should be
replaced if webbing becomes
frayed, contaminated or damaged.
It is essential to replace the entire
assembly after it has been worn in
a severe impact even if damage to
the assembly is not obvious. Belts
should not be worn with straps
twisted. Each seat belt assembly
must only be used by one occu-
pant; it is dangerous to put a belt
around a child being carried on the
occupant's lap.
WARNING
No modifications or additions
should be made by the user which
will either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted
to remove slack.
(Continued)
Avoid wearing twisted seat belts.
A twisted belt can't do its job as
well. In a collision, it could even
cut into you. Be sure the belt
webbing is straight and not twist-
ed.
Be careful not to damage the belt
webbing or hardware. If the belt
webbing or hardware is dam-
aged, replace it.
WARNING
For maximum restraint system
protection, the seat belts must
always be used whenever the car
is moving.
Seat belts are most effective
when seatbacks are in the
upright position.
Children age 12 and younger
must always be properly
restrained in the rear seat. Never
allow children to ride in the front
passenger seat. If a child over 12
must be seated in the front seat,
he/she must be properly belted
and the seat should be moved as
far back as possible.
Never wear the shoulder belt
under your arm or behind your
back. An improperly positioned
shoulder belt can cause serious
injuries in a crash. The shoulder
belt should be positioned midway
over your shoulder across your
collarbone.
