8. After charging has started, theestimated charging time is dis-
played on the instrument cluster
for about 1 minute. It is also dis-
played, when the driver’s door is
opened with charging in progress.
When scheduled charging is set,

10. Check if the charging cable con-
nection indicator of the high volt-
age battery in the instrument
cluster is turned ON.
Charging does not occur when
the indicator is OFF. When the
charging connector is not con-
nected properly, reconnect the
charging cable to charge.
Information
• The charging is in progress only with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the battery
with the Engine Start/Stop button in
the OFF position.
• Moving the shift lever from P (Park) to R (Reverse)/N(Neutral)/D (Drive)
stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable and restart the
vehicle again. 11. After charging has started, the

Starting the vehicle
1. Carry the smart key or leave it
inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Place the shift lever in P (Park). With the shift lever in N (Neutral),
you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop but- ton. If the hybrid system starts, the
" " indicator will come on and a
double chime can be heard.
Whether the engine is cold or warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, " " indicator on the
instrument cluster will turn on.
For more information, please
check Chapter 5. ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a
moderate rate and maintain a
steady cruising speed. Do not
make "jack-rabbit" starts. Do not
race between stoplights.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
The regenerative brake generates energy when the vehicle deceler-
ates.
When the hybrid battery power is low, the hybrid system automatical-
ly recharges the hybrid battery.
When the engine is running with the shift lever in N (Neutral), the
hybrid system cannot generate
electricity. The hybrid battery can-
not recharge with the shift lever in N
(Neutral).
Information
In the hybrid system, the engine auto-
matically runs and stops. When the
hybrid system operates, the " "
indicator is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is beingcharged
- Depending on the temperature con- dition of the hybrid battery
i
To avoid serious injury, turn off
hybrid system and be sure " "
indicator is off before working
under hood. Engine may start
unexpectedly.
WARNING

H23
Special features
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 system.
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 compart-
ment. None of these sounds indicate
a problem. These are normal charac-
teristics 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.
When the hybrid system is turned
ON, the gasoline engine may acti-
vate or may not. In this situation, you
may feel a vibration. This does not
indicate a malfunction. When the
" " indicator illuminates, the
hybrid system is ready to begin driv-
ing. Even if the engine is off, you can
operate the vehicle as long as the
" " indicator is illuminated. The hybrid system contains many
electronic components. High volt-
age components, such as cables
and other parts, may emit electro-
magnetic waves. Even when the
electromagnetic cover blocks elec-
tromagnetic emissions, electro-
magnetic waves may have an
effect on electronic appliances.
When your vehicle is not used for
a long period of time, the hybrid
system will discharge. You need to
drive the vehicle several times a
month. We recommend driving at
least for 1 hour or 10 miles. When
the hybrid battery is discharged,
or when it is impossible to jump
start the vehicle, contact your
HYUNDAI dealer.

Virtual Engine Sound System
(VESS)
The Virtual Engine Sound System
generates engine sounds for pedes-
trians to hear vehicle sound because
there is limited sound while electric
power is used.
What Does RegenerativeBraking Do?
It uses an electric motor when decel-
erating and braking and transforms
kinetic energy to electrical energy in
order to charge the high voltage bat-
tery.
Battery
The vehicle is composed of a high-
voltage battery that drives the
motor and air-conditioner, and an
auxiliary battery (12 V) that drives
the lamps, wipers, and audio sys-
tem.
The auxiliary battery is automati- cally charged when the vehicle is in
the ready ( ) mode.
Hybrid system gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
CHARGE :
Shows that the energy made by
the vehicle is being converted
to electrical energy. (Regenerated
energy)
ECO : Shows that the vehicle is being
driven in an Eco-friendly manner.
POWER : Shows that the vehicle is exceeding
the Eco-friendly range.
When you start the hybrid
system with the shift lever in
P (Park), the " " indicator
illuminates on the instrument
cluster. The driver can drive
the vehicle, even when the
gasoline engine is off.
When you leave the vehicle,
you should turn OFF the vehi-
cle and place the shift lever in
P (Park). If you depress the
accelerator pedal by mistake,
or when the shift lever is not
in P (Park), the vehicle will
abruptly move, possibly
resulting in serious injury or
death.
WARNING

H25
According to the hybrid system
gauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is drivenusing the electric motor or the
gasoline engine is stopped.
- "EV" indicator OFF : Vehicle is driv- en using the gasoline engine.Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "L (Low)" level, the vehicle
automatically operates the engine to
charge the battery. However, if the Service Indicator ( )
and Malfunction Indicator Lamp (MIL)
( ) turn on when the SOC (State of
charge) gauge is near the "L (Low)"
level, have the vehicle checked by an
authorized HYUNDAI dealer.
