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.
DRIVING THE HYBRID VEHICLE

01
1-51
When the hybrid system is turned ON,
the gasoline engine may run 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 driving.
Even if the engine is off, you can operate
the vehicle as long as the “
” indicator
is illuminated.
NOTICE
The hybrid system contains many
electronic components. High voltage
components, such as cables and other
parts, may emit electromagnetic waves.
Even when the electromagnetic cover
blocks electromagnetic emissions,
electromagnetic waves may have an
effect on electronic devices. 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. Drive 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
authorized HYUNDAI dealer.
WARNING
• When you start the hybrid system
with the shift button in P (Parking),
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 hybrid system
or locate the shift button in P (Park).
When you depress the accelerator
pedal by mistake, or when the shift
button is not in P (Park), the vehicle
will abruptly move, possibly resulting
in serious injury or death.
Virtual Engine Sound System (VESS)
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
limited sound while motor power is used.
• When the engine is running, the gear
shift button is not in P (Park), the VESS
will operate.
• When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
What does regenerative braking do?
It uses an electric motor when
decelerating and when braking and
transforms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
• Hybrid
- The vehicle is composed of a high
voltage battery that drives the motor
and air conditioner, and an integrated
12V lead battery with the HEV battery
that drives the lamps, wipers, and audio
system.
- The integrated 12V battery is automatically charged when the vehicle
is in the ready (
) mode.
• Plug-in hybrid vehicle
- 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
system.
- The auxiliary battery is automatically charged when the
vehicle is in the ready (
) mode.
