Safety plug
This safety plug (1) located in the rear
trunk as shown should always be pulled
out to disconnect and turn off the hybrid
system.
IMPORTANT: Wait 5 minutes after this
lever is disconnected to work on the
car to assure all remaining charge in
the system has dissipated.
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
an unconventional sound. When you
apply the brake pedal, you may hear a
sound from the regenerative brake sys-
tem. When the hybrid system 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 compartment. None
of these sounds indicate a problem.
These are normal characteristics of
hybrid vehicles.
If any of following occur, it's a normal
condition if you 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.
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 careful
because burns or electric shock
may be caused by high voltage.
Do not drop water or liquid on to
HPCU, HSG, Motor and fuses. The
hybrid system components are
covered. If you drop water or liq-
uid on to hybrid system compo-
nents, it may result in electric
shock.
DANGER
Never touch the safety plug. Safety
plug is attached to high voltage
hybrid battery system. Touching
safety plug will result in death or seri-
ous injury. Service personnel should
follow procedure in service manual.

H11
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 as long as the
"READY" symbol is illuminated.Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System gener-
ates engine sound for pedestrians to
hear vehicle sound because there is no
sound while motor power is used.
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.
CAUTION
The hybrid system contains many
electronic components. High volt-
age components like cables and
other parts may emit electromag-
netic waves. Even if the electromag-
netic cover blocks electromagnetic
emissions, electromagnetic waves
may have an effect on electronic
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 vehi-
cle. If the hybrid battery is dis-
charged and if it is impossible to
jump start the vehicle contact your
Hyundai dealer.

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 obstruct 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 air 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 or near the air intake. If the liq-
uid spills, the hybrid battery locat-
ed in the trunk may be damaged.
Secure all loads in the trunk from
moving while the vehicle is in
motion. If a sharp or heavy load
were to impact or pierce the inte-
rior trunk wall the hybrid battery
system could be damaged and/or
lose function.
