HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
Hybrid Vehicle
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a 270V high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the electric motor with the HEV bat-
tery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

Charging Information
•Normal Charge :
The plug-in hybrid vehicle is
charged by plugging into a normal
charger installed in your home or a
public charging station. (For further
details, refer to the 'Normal
Charge'.)•Trickle Charge :
The plug-in hybrid vehicle can be
charged by using household elec-
tricity. The electrical outlet in your
home must comply with regulations
and can safely accommodate the
Voltage / Current (Amps) / Power
(Watts) ratings specified on the
portable charge.
Charging Time
•Normal Charge :
Takes approximately 2 hours 15
minutes at room temperature. (Can
be charged to 100%.)
Information
Depending on the condition and dura-
bility of the high voltage battery, charg-
er specifications, and ambient tempera-
ture, the time required for charging the
high voltage battery may vary.

H127. Check if the charging indicator
light of the high voltage battery on
the instrument cluster is turned
ON. Charging is not done when
the charging indicator lamp is
OFF.
When the charging connector and
charging plug are not connected
properly, reconnect the charging
cable to charge.
Information
• Even though charging is possible
with the ignition switch in the
ON/START position, for your safe-
ty, start charging when the ignition
switch is in the LOCK/OFF position
and the vehicle shifted to P (Park).
After charging has started, you can
use electrical components such as
the radio by placing the ignition
switch in the ACC or ON position.
• During normal charging, the radio
reception may be bad.
• 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),
place the ignition switch to the
LOCK/OFF position, and discon-
nect the charging cable. Then, con-
nect the charging cable.8. After charging has started, the esti-
mated charging time is displayed on
the instrument cluster for about 1
minute.
If you open the driver seat door while
charging, the estimated charging
time is also displayed on the instru-
ment cluster for about 1 minute.
When scheduled charging is set, the
estimated charging time is displayed
as “--" .
Information
Depending on the condition and dura-
bility of the high voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the battery may vary.

Charging connector AUTO/LOCK
mode
The charging connector is locked in
the inlet at a different period accord-
ing to which mode is selected.
• LOCK mode : The connector locks
when the charging connector is
plugged into the charging inlet.
• AUTO mode : The connector locks
when charging starts.
For more details, refer to “Charging
Connector AUTO/ LOCK Mode” in
this chapter.8. Charging starts automatically
(charging lamp blinks).9. Check if the charging indicator
light of the high voltage battery on
the instrument cluster is turned
ON. Charging is not done when
the charging indicator lamp is
OFF.
When the charging connector is
not connected properly, reconnect
the charging cable to charge it
again.
