Service plug
This service 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 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
loads may have an effect on
package modules causing dam-
age and loss of function.

If An Accident OccursWhen the hybrid vehicle shuts off
When the high voltage battery dis-
charged, 12-volt battery discharged, or
fuel tank is empty, the hybrid system may
not operate while driving. If the Hybrid
system is not operated, do the following;
1. Reduce the vehicle speed gradually.
Pull your vehicle off the road as safe
area.
2. Shift the transmission into "P" position.
3. Turn on the hazard warning flashers.
4. Set the start button at OFF, and try to
start the Hybrid system by applying the
brake pedal and pushing the start but-
ton.
5. If the Hybrid system will not operate,
refer to "EMERGENCY STARTING" in
chapter 6.
When you try to jump start the vehicle,
confirm the fuel level and exact proce-
dure of jump start. For details, see the
"EMERGENCY STARING" in chapter 6.
