Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded gasoline with
an octane rating of RON 91-94 / AKI
87-90 but it may result in slight per-
formance reduction of the vehicle. (Do
not use methanol blended fuels)
Except Europe
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher. (Do not use methanol
blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorized HYUNDAI dealer for
details.)
NOTICE
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Starting the Vehicle
Vehicles with remote key system
1.Make sure the parking brake is
applied.
2.Make sure the shift lever is in P
(Park).
3.Depress the brake pedal.
4.Turn the ignition swich to the
START position. Hold the key
(maximum of 10 senconds) until
the " " comes on and release it.
Whether the engine is cold or
warm, it should be started without
depressing the accelerator.
After following the start proce-
dures, “ ” indicator on the
instrument cluster will turn on.
For more information, please check
Chapter 5.
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.Place the shift lever in P (Park).
With the shift lever in N (Neutral),
you cannot start the vehicle.
4.Depress the brake pedal.
5.Press the Engine Start/Stop but-
ton. 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 proce-
dures, “ ” indicator on the
instrument cluster will turn on.
For more information, please check
Chapter 5.ECONOMICAL and SAFE OPERA-
TION 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 pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear out.
• The regenerative brake generates
energy when the vehicle deceler-
ates.
• When the hybrid battery power is
low, the hybrid system automatical-
ly recharges the hybrid battery.
• When the engine run with the shift
lever in N (Neutral), the hybrid sys-
tem cannot generate electricity. The
hybrid battery cannot recharge with
the shift lever in N (Neutral).

Hybrid Battery SOC
(State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "0 or L (Low)" level, the
vehicle automatically operates the
engine to charge the battery.However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the "0 or L (Low)"
level, we recommend the vehicle be
checked by an authorized HYUNDAI
dealer.
Plug-in Hybrid Mode
(Plug-in hybrid vehicle)
EV/HEV Button
Pressing the [EV/HEV] button
changes the plug-in hybrid system
modes, between Electric (CD) mode
and Hybrid (CS) mode.
Each time the mode is changed a
corresponding indicator is displayed
on the instrument cluster as follows.

• When the vehicle is paint baked,
do not bake over 30 minutes in
70°C (158°F) or 20 minutes in
80°C (176°F) degree.
• Do not wash the engine compart-
ment, using water. Water may
cause an electric shock to and
damage the electronic.
NOTICE
•Never use the package mod-
ules (high voltage battery,
inverter and converter) for any
other purpose.
•Do not use an unauthorized
battery charger to charge the
high voltage battery. Doing so
may result in death or serious
injury.
•Never locate the high voltage
system near or in a fire.
•Never drill into or strike the
package module. Otherwise, it
may be damaged. An electric
shock may occur, resulting in
serious injury or death.
WARNING
•Do not disassemble or assem-
ble the high voltage battery
system. Doing so may result
in electric shock, causing
death or serious injury.
•If you disassemble or assem-
ble hybrid system compo-
nents improperly, it may dam-
age the performance and reli-
ability of your vehicle.
•If electrolyte comes in contact
with your body, clothes or
eyes, immediately flush with a
large quantity of fresh tap
water. Have your eyes exam-
ined by a doctor as soon as
possible.
WARNING
Never assemble or disassemble
the high voltage battery system.
•If you assemble or disassem-
ble the high voltage battery
system, the durability and per-
formance of the vehicle may be
damaged.
•When you want to check the
high voltage battery system,
have the vehicle checked and
inspected by an authorized
HYUNDAI dealer.
•Do not touch the high voltage
battery and high voltage cable
connected to motor (orange
color). Severe burns and elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not remove
the cover of electronic compo-
nents and electronic cable. In
particular, never touch the high
voltage battery system when
the hybrid system in operation.
It may result in death or serious
injury.
WARNING

SRS warning light
The SRS (Supplement 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 indi-
cates that there is a potential problem
with your air bag system.During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags,
at the time and with the force needed.
The front air bags help protect the driv-
er 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 by supporting
the side upper body area.
• Air bags are activated (able to inflate
if necessary) only when the ignition
switch is in the ON position.
• Air bags inflate in the event of certain
frontal or side collisions to help pro-
tect 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 direc-
tion. These two factors determine
whether the sensors produce an elec-
tronic deployment/inflation signal.
Safety system of your vehicle
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 malfunction-
ing:
•The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
•The light stays on after illumi-
nating for approximately six
seconds.
•The light comes on while the
vehicle is in motion.
•The light blinks when the
engine is running.
We recommend that an author-
ized HYUNDAI dealer inspect the
SRS as soon as possible if any
of these conditions occur.
