VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its
performance, safety or durability and may even violate governmental safety and
emissions regulations.
In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate
abnormally, wire damage, battery discharge and fire. For your safety, we
recommend that you do not use unauthorized electronic devices.
VEHICLE BREAK-IN PROCESS
By following a few simple precautions for the first 600 miles (1,000 km) you may add to
the performance, economy and life of your vehicle.
• Do not race the engine.
• While driving, keep your engine speed (rpm, or revolutions per minute) between
2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying
engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.

VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
This vehicle is equipped with an event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by the EDR under normal
driving conditions and no personal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law enforcement, could combine the
EDR data with the type of personally identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equipment, can read the information if
they have access to the vehicle or the EDR.

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

Warning and indicator lights
Ready indicator
This indicator illuminates:
When the vehicle is ready to be driven.
-ON : Normal driving is possible.
-OFF : Normal driving is not possible,
or a problem has occurred.
-Blinking : Emergency driving.
When the ready indicator goes OFF
or blinks, there is a problem with the
system. If this occurs, we recommend
that you have your vehicle inspected by
an authorized HYUNDAI dealer.
EV mode indicator
This indicator illuminates:
When the vehicle is driven by the electric
motor.
Service warning light
This warning light illuminates:
• When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
-The service warning light illuminates
for approximately 3 seconds and
then turns off when all checks have
been performed.
• When there is a problem with the
hybrid vehicle control system or
hardware.
When the warning light illuminates
while driving, or does not go OFF after
starting the vehicle, we recommend that
you have the vehicle inspected by an
authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and have
your vehicle inspected by an authorized
HYUNDAI dealer. The operation of the
brake pedal may be more difficult than
normal and the braking distance may
increase.

WARNING
If a fire occurs:
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the hybrid vehicle shuts
off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P
(Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to
start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does
not operate, refer to “Jump starting”
section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “Jump starting”
section in chapter 8. When the fuel
level is low, do not attempt to drive
the vehicle only with the battery
power. The high voltage battery may
be discharged, and the hybrid system
will turn OFF.
