Hybrid Vehicle
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the petrol engine and the electric motor for power. The electric
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.

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 AC 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

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.

Starting the Vehicle
Vehicles with remote key system
1. Make sure the parking brake is
applied.
2. Make sure the shift lever is in P
(Park).
3. Depress the brake pedal.
4. Turn the ignition swich to the
START position. Hold the key
(maximum of 10 senconds) until
the " " indicator comes on and
release it.
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.
Vehicles with smart key system
1. Carry the smart key or leave it
inside the vehicle.

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.
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 being
charged
- Depending on the temperature con-
dition of the hybrid battery
Special Features
Hybrid vehicles sound different than
petrol 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 petrol engine may run or
may not. In this situation, you may
feel a vibration. This does not indi-
cate a malfunction. When the “ ”
indicator illuminates, the hybrid sys-
tem is ready to begin start. Even if the
engine is off, you can operate the
vehicle as long as the “ ” indicator
is illuminated.

Cycle Mode :
When the vehicle is OFF with all
doors, bonnet and tailgate closed,
the Aux. Battery Saver+ periodically
activates according to the auxiliary
battery status.
Automatic Mode :
When the ignition switch is in the ON
position with the charging connector
plugged in, the function activates
according to the auxiliary battery sta-
tus to prevent overdischarge of the
auxiliary battery.Information
• The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function
will stop activating, judging that

battery. In this case, drive the vehi-
cle for some period of time. The
function will start activating if the
auxiliary battery returns to normal.
• The Aux. Battery Saver+ function
cannot prevent battery discharge if
the auxiliary battery is damaged,
worn out, used as a power supply or
unauthorised electronic devises are
used.
• If the Aux. Battery Saver+ function
was activated, the high voltage bat-
tery level may have decreased.
System Setting
The driver can activate the Aux.
Battery Saver+ function by placing
the ignition switch to the ON position
and by selecting:
