The Hyundai Hybrid Electric Vehicle
(HEV) uses a gasoline engine and an
electric motor for power. The electric
motor is run from a 280V high voltage
HEV battery.
Depending on the driving conditions,
the HEV computer decides whether to
use the engine or use the electric
motor or even both at times.
Fuel is saved when the engine is not
running at idle or when the vehicle is
driven by the electric motor from the
HEV battery.
The HEV battery charge must be
maintained for the times when the
engine acts as a generator, such as
when stopped at idle. Charging also
occurs when decelerating or by
regenerative braking.Display of Hybrid system
Many displays provide information about
the hybrid system, such as, ECO level
and ECO score.
Through the ECO LEVEL, the driver can
understand the benefits of economical
driving.
If the driver is using economical driving
techniques, the ECO LEVEL rises. This
means the CO2 emissions are reduced.
In TOTAL ECO SCORE, when you reach
the maximum step of ECO LEVEL, the
ECO system calculates the score and
saves the score.ECO level display flower mode.1
When the hybrid vehicle is started, the
ECO level step 4 is displayed. If you drive
economically, the ECO level will be
upgraded.
- However, if you do not drive economically,
the ECO level will be down-graded.

ECO level display flower mode.2
In the “vehicle setting”, if you change the
animation mode to "ON", the dynamic
image will be activated.
- This provides the driver with the
dynamic ECO mode.Total ECO score display
If your ECO level achieves the top step,
your ECO score automatically saves 1
point.
In the “vehicle setting”, if you change the
animation mode to “ON”, the dynamic
image will be on.SOC Gauge (State of charge)
This State of Charge(SOC) gauge indi-
cates the remaining Hybrid battery
power. If the SOC is near L level, the
vehicle automatically operates the
engine to charge the battery. However, if
the service indicator and
MIL(Malfunction indicator lamp) turn on
when the State of Charge(SOC) is near
L(Low), the vehicle should be towed.
Refer to Chapter 6 for towing information.

The Hyundai SONATA hybrid system
notifies customers of its energy flow
through MODE.
While driving, eleven MODEs show driv-
ers the current operating system.
Vehicle Stop
This mode means the
vehicle is stopped.

Starting the engine
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 the P(Park)
position. In N(Neutral) position, you
can not start the vehicle.
4. Depress the brake pedal.
5. Press the engine start/stop button.
6. In extremely cold weather or after the
vehicle has not been operated for sev-
eral days, let the engine warm up with-
out depressing the accelerator.
Whether the engine is cold or warm, it
should be started without depressing
the accelerator.

if it is far away from you, the engine
may not start.

in the ACC or ON position, if any door
is open, the system checks for the
smart key. If the smart key is not in
the vehicle, the warning, "Key is not
in vehicle" will come on, and if all
doors are closed, the chime will also
sound for about 5 seconds. The indi-
cator will turn off while the vehicle is
moving. Keep the smart key in the
vehicle when using the ACC position
or if the vehicle engine is on.If the starting procedure is followed,
the "READY" symbol on the instru-
ment cluster will turn on. For more
details, please check Chapter 5.
ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a moder-
ate rate and maintain a steady cruising
speed. Don't make "jack-rabbit" starts.
Don't race between stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
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 runs in "N" position,
the hybrid system can not generate
electricity. The hybrid battery cannot
recharge in "N" position. Please check
Chapter 5.
✽ ✽
NOTICE
In the hybrid system, the engine auto-
matically runs and stops. If the hybrid
system operates, the "READY" symbol
is illuminated.
In the following situation, the engine
may operate automatically.
- When the engine is ready to run
- When the hybrid battery is charged
- Depending on the temperature condi-
tion of the hybrid battery
STARTING THE HYBRID VEHICLE (SMART KEY)
WARNING
To avoid serious injury, turn off
ignition and be sure "READY" lamp
is off before working under hood.
Engine may start unexpectedly.

THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
In the hybrid system, the hybrid bat-
tery uses high voltage to operate the
motor and other components. This
high voltage hybrid battery system
can be very dangerous. Never touch
the hybrid system. If you touch the
hybrid battery system, serious
injury or death may occur.
WARNING
Never touch orange or high voltage
labeled components including
wires, cables, and connections. If
the insulators or covers are dam-
aged or removed, severe injury or
death from electrocution may occur.
WARNING
When replacing the fuses in the
engine compartment, never touch
the HPCU. The HPCU carries high
voltage. Touching the HPCU could
result in electrocution, serious
injury, or death.

WARNING
• Do not disassemble the high volt-
age motor connector. The high
voltage motor connector may con-
tain residual high voltage. Coming
in contact with high voltage may
result in death or serious injury.
Your vehicle's hybrid system
should only be inspected or
repaired by an authorized
Hyundai dealer.
