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.

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, 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. - “EV” indicator ON : Vehicle is driven using the electric motor or the
gasoline engine is stopped.
- “EV” indicator OFF : Vehicle is driven using the gasoline engine.
Charging Cable Connection
Indicator (Plug-in hybrid
vehicle)
This indicator illuminates in red when the
charging cable is connected. 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, 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.

SRS warning light
The SRS (Supplemental Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:
[ The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is in the ON position.

[ The light stays on after illuminating
for approximately three to six seconds.

[ The light comes on while the vehicle
is in motion.

[ The light blinks when the engine is running.
an authorized HYUNDAI dealer inspect
the SRS as soon as possible if any of
these conditions occur. During a moderate to severe frontal
collision, sensors will detect the
vehicle’s rapid deceleration. If the rate of
deceleration is high enough, the control
unit will inflate the front air bags, at the
time and with the force needed.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover by supporting the side upper
body area.
[
Air bags are activated (able to
inflate if necessary) only when the
Engine Start/Stop button is in the
ON or START position, and it can be
activated within about 3 minutes after
the engine is turned off.

[ Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.

[ There is no single speed at which the
air bags will inflate. Generally, air bags
are designed to inflate based upon the
severity of a collision and its direction.
These two factors determine whether
the sensors produce an electronic
deployment/inflation signal.

[ The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after the collision.
