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.

• If boxes or objects are stacked in the
vehicle, the system may not detect
the boxes or objects. Or, the alert may
operate if the boxes or objects fall off.
• The sensor may not operate normally
if the senor is blocked with foreign
substances.
• The alert may operate if movement
in the driver or passenger seat is
detected.
• The alert may operate with the doors
locked due to car wash or surrounding
vibration or noise.
• If the vehicle is started remotely (if
equipped with Remote Start), inside
movement detection will stop.
WARNING
Even if your vehicle is equipped with
Rear Occupant Alert, always make sure
to check the rear seat before you leave
the vehicle.
Rear Occupant Alert may not operate
when:
• Movement does not continue for
a certain period of time or the
movement is small.
• The rear passenger is covered with
an object such as a blanket.
• Always be cautious of the
passenger’s safety as the detection
function and second alert may
not operate depending on the
surrounding environment and
certain conditions.

The Pre-Tensioner Seat Belt System
consists mainly of the following
components. Their locations are shown
in the illustration above:
(1)
SRS air bag warning ligh
t
(2)
Re

tractor pre-tensioner
(3)
SRS contr

ol module
(4)
Emer

gency fastening device
NOTICE
The sensor that activates the SRS
control module is connected with the
pre–tensioner seat belts. The SRS air
bag warning light on the instrument
cluster will illuminate for approximately
3~6 seconds after the Engine Start/Stop
button is in the ON position, and then it
should turn off.
If the pre-tensioner is not working
properly, the warning light will
illuminate even if the SRS air bag is not
malfunctioning. If the warning light
does not illuminate, stays illuminated
or illuminates when the vehicle is
being driven, we recommend the pre-
tensioner seat belts and/or SRS control
module be inspected by an authorized
HYUNDAI dealer as soon as possible.
Information
• Pre-tensioner seat belts may be
activated in certain frontal or side
collisions or rollover situations (if
equipped with rollover sensor).
• When the pre-tensioner seat belts are
activated, a loud noise may be heard
and fine dust, which may appear to be
smoke, may be visible in the passenger
compartment. These are normal
operating conditions and are not
hazardous.
• Although it is non-toxic, the fine dust
may cause skin irritation and should
not be inhaled for prolonged periods.
Wash all exposed skin areas thoroughly
after an accident in which the pre-
tensioner seat belts were activated.

WARNING
To reduce the risk of serious injury or
death from an inflating side air bag and
front center air bag, take the following
precautions:
• Seat belts must be worn at all times
to help keep occupants positioned
properly.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Hold the steering wheel at the 9
o’clock and 3 o’clock positions, to
minimize the risk of injuries to your
hands and arms.
• Do not use any accessory seat
covers. This could reduce or prevent
the effectiveness of the system.
• Do not hang other objects except
clothes. In an accident it may cause
vehicle damage or personal injury
especially when air bag is inflated. •
Do not place any objects over the
air bag or between the air bag and
yourself. Also, do not attach any
objects around the area the air bag
inflates such as the door, side door
glass, front and rear pillar.
• Do not place any objects between
the door and the seat. They may
become dangerous projectiles if the
side air bag inflates.
• Do not install any accessories on the
side or near the side air bags.
• Do not cause impact to the doors
when the Engine Start/Stop button
is in the ON or START position as this
may cause the side air bags to inflate.
• If the seat or seat cover is damaged,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.

How does the air bags system
operate?
ONX4030055
The SRS consists of the following
components:
(1)
Driver's fr
ont air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Emergency fastening device system
(12) Occupant classification system
(13) Seat belt buckle sensor
The SRSCM continually monitors all SRS
components while the ignition switch
is ON to determine if a crash impact
is severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
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.
We recommend that an authorized
HYUNDAI dealer inspect the SRS
as soon as possible if any of these
conditions occur.
