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
1-11
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. We recommend driving
at least for 1 hour or 10 miles. When the
hybrid battery is discharged, or when it
is impossible to jump start the vehicle,
we recommend that you 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
• 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.

Where are the air bags?
Driver’s and passenger’s front air
bags
„„Driver’s front air bag
OTM030006
„„Passenger’s front air bag
OTM030007
Your vehicle is equipped with a
Supplemental Restraint System (SRS)
and lap/shoulder belts at both the driver
and passenger seating positions.
The SRS consists of air bags which are
located in the center of the steering
wheel and the passenger’s side front
panel pad above the glove box.
The air bags are labeled with the letters
“AIR BAG” embossed on the pad covers.
The purpose of the SRS is to provide the
vehicle’s driver and front passengers with
additional protection than that offered
by the seat belt system alone in case of a
frontal impact of sufficient severity.The SRS uses sensors to gather
information about the driver’s and front
passenger's seat belt usage and impact
severity.
The seat belt buckle sensors determine
if the driver and front passenger's seat
belts are fastened. These sensors provide
the ability to control the SRS deployment
based on whether or not the seat belts
are fastened, and how severe the impact
is.
The advanced SRS offers the ability to
control the air bag inflation within two
levels. A first stage level is provided for
moderate-severity impacts. A second
stage level is provided for more severe
impacts.
According to the impact severity, and
seat belt usage, the SRS Control Module
(SRSCM) controls the air bag inflation.
Failure to properly wear seat belts can
increase the risk or severity of injury in an
accident.

Seats & Safety System
3-52
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. •
In addition to inflating in serious side
collisions, vehicles equipped with a
rollover sensor, side and/or curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, curtain
air bags will remain inflated longer to
help provide protection from ejection,
especially when used in conjunction
with the seat belts. (if equipped with a
rollover sensor)
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or
lifethreatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to reduce the risk
of being injured by an inflating air bag.
The greatest risk is sitting too close to
the air bag. An air bag needs about 10
in. (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 in. (25 cm) between the center of the
steering wheel and the chest.
