Unleaded
Your new vehicle is designed to perform optimally using unleaded fuel having an
octane number((R+M)/2) of 87 (Research Octane Number 91) or higher. (Do not use
methanol blended fuels)
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimize exhaust emissions and spark plug fouling.
NOTICE
To prevent damage to the engine and engine components, never add any fuel
system cleaning agents to the fuel tank other than what has been specified.
Consult an authorized HYUNDAI dealer for additional information.
WARNING

[Do not “top off” after the nozzle automatically shuts off when refueling.

[ Always check that the fuel cap is installed securely to prevent fuel spillage in the
event of an accident.
Gasoline containing alcohol and methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) are being
marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is a
gasohol comprised of 15% ethanol and 85% gasoline.
Do not use gasohol containing more than 10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either of these fuels may cause drivability problems
and damage to the fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if drivability problems occur.
“E85” fuel is an alternative fuel comprised of 85 percent ethanol and 15 percent
gasoline, and is manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is
not compatible with your vehicle. Use of “E85” may result in poor engine performance
and damage to your vehicle’s engine and fuel system. HYUNDAI recommends that
customers do not use fuel with an ethanol content exceeding 15 percent.
NOTICE
To prevent damage to your vehicle’s engine and fuel system:

[Never use gasohol which contains methanol.

[ Never use gasohol containing more than 15% ethanol.

[ Never use leaded fuel or leaded gasohol.

[ Never use “E85” fuel.
Your New Vehicle Limited Warranty does not cover damage to the fuel system or any
performance problems caused by the use of “E85” fuel.
FUEL REQUIREMENTS

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. 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,
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 external AGM
type 12V battery that drives the lamps,
wipers, and audio system.

[ The battery is automatically charged
when the vehicle is in the ready (
)
mode.
