The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both
a conventional hybrid electric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively
operates between the engine and the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the
electric motor over a certain distance until the hybrid battery becomes low. The driving
distance in EV mode depends on customer driving style and road conditions.
Aggressive driving maneuvers or in need of diagnosis for emission related parts, may
enable the engine to operate. However, engine power can be limited during emission
reduction control period in cold engine condition.
The hybrid battery can be fully charged by connecting a plug to an external electric
power source.

Information

[ Even though charging is possible with
the ignition switch in the ON/START
position, for your safety, 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 ACC
or ON 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), place the
ignition switch to the LOCK/OFF position, and disconnect the charging
cable. Then, connect the charging cable.

Starting the Vehicle
Vehicles with smart key system
1. Carry the smart key or leave it inside the vehicle.
2. Make sure the parking brake is firmly applied.
3. Make sure the shift button is in P (Park). With the shift button in N
(Neutral), you cannot start the vehicle.
4. Depress the brake pedal.
5. Press the Engine Start/Stop button. 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 procedures, “
” indicator on the instrument
cluster will turn on. For more details,
please check chapter 6.
ECONOMICAL and SAFE OPERATION 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 possible.
Always maintain a safe distance
from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear out.

[ The regenerative brake generates
energy when the vehicle decelerates.

[ When the hybrid battery power is
low, the hybrid system automatically
recharges the hybrid battery.

[ When the engine is running with the
shift button in N (Neutral), the hybrid
system cannot generate electricity.
The hybrid battery cannot recharge
with the shift button in N (Neutral).
Information
In the hybrid system, the engine
automatically 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 condition of the hybrid battery
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 under the floor. 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
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.
