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.

Plug-in Hybrid Vehicle
The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid elec-
tric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and
the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain dis-
tance until the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and
road conditions. Aggressive driving maneuvers may at times temporarily enable the engine to operate for maximum
power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.

Information
Charging connector AUTO/LOCK
mode
The charging connector is locked in
the inlet at a different period accord-
ing to which mode is selected.
• LOCK mode : The connector locks
when the charging connector is
plugged into the charging inlet.
• AUTO mode : The connector locks
when charging starts.
For more details, refer to “Charging
Connector AUTO/ LOCK Mode” in
this chapter.8. Charging starts automatically
(charging lamp blinks).9. Check if the charging indicator
light of the high voltage battery on
the instrument cluster is turned
ON. Charging is not done when
the charging indicator lamp is
OFF.
When the charging connector is
not connected properly, reconnect
the charging cable to charge it
again.

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).

What Does Regenerative
Braking Do?
It uses an electric motor when decel-
erating and when braking and trans-
forms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
• Hybrid
- The vehicle is composed of a
high voltage battery that drives
the motor and air conditioner, and
an integrated 12V lithium ion
polymer battery with the HEV
battery that drives the lamps,
wipers, and audio system.
- The integrated 12V battery is auto-
matically charged when the vehicle
is in the ready ( ) mode.
• Plug-in hybrid vehicle
- The vehicle is composed of a
highvoltage battery that drives
the motor and air-conditioner,
and an auxiliary battery (12 V)
that drives the lamps, wipers, and
audio system.
- The auxiliary battery is automati-
cally charged when the vehicle is
in the ready ( ) mode.
Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
• CHARGE :
Shows that the energy made by
the vehicle is being converted
to electrical energy. (Regenerated
energy)
• ECO :
Shows that the vehicle is being
driven in an Eco-friendly manner.
• POWER :
Shows that the vehicle is exceeding
the Eco-friendly range.According to the hybrid system
gauge area, the "EV" indicator comes
on or off.
- "EV" indicator ON : Vehicle is driven
using the electric motor or the
gasoline engine is stopped.
- "EV" indicator OFF : Vehicle is driv-
en using the gasoline engine.

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.

or the [All menus] screen and the
menus related to plug-in hybrid
([ECO driving], [Energy information],
[EV range], [Set charging times],
[Charging stations], [Petrol stations])
are displayed.
For more information, please refer
to the Multimedia System Manual
that was separately supplied with
your vehicle.
Aux. Battery Saver+
(Plug-in hybrid vehicle)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12 V auxiliary battery. If the aux-
iliary battery level is low, the main
high voltage battery charges the aux-
iliary battery.
Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the cluster. For more information,
refer to the following page.
