Introduction
Fuel Additives
HYUNDAI recommends that you use good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at every 12,000 km(7,500 miles) or 12 months is recom-mended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. No special break-in period is needed.
By following a few simple precautions
for the first 1,000 km (600 miles) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.

Introduction
This vehicle is equipped with an
event data recorder (EDR). Themain purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will assist
in understanding how a vehicle's
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
vehicle were operating;
passenger safety belts were
buckled/ fastened;
depressing the accelerator
and/or brake pedal; and,
ing. These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle onlyif a non-trivial crash situation
occurs; no data are recorded bythe EDR under normal driving
conditions and no personal data
(e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as
law enforcement, could combinethe EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investiga-tion.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such
as law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.

HHEEVV (( HH YY BBRRIIDD EE LLEE CCTT RR IICC VV EEHH IICC LLEE )) SS YY SSTT EEMM
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is off at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

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 for over a certain
distance 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 maxi-
mum power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.

Charging Information
• Normal Charger (Stage-2 type): The
plug-in hybrid vehicle is charged by
plugging into a normal charger
installed in your home or a public
charging station. (For further
details, refer to the ‘Normal charg-
ing.’) Trickle Charger (Stage-1 type): The
plug-in hybrid vehicle can be emer-
gently charged by using household
electricity.
The electrical outlet in your home
must comply with regulations and
can safely accommodate the
Voltage / Current (Amps) / Power
(Watts) ratings specified on the
trickle charge.
Charging Time
• Normal Charger (Stage-2 type):
Takes about 2-3 hours at room tem-
perature (Can be charged to 100%.).Depending on the condition and
durability of the high-voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the high-voltage battery
may vary.

Charging Status
You can monitor the charging status
outside of the vehicle when charging
the high-voltage battery.
Scheduled Charging (if equipped)
You can set-up a charging sched-ule for your vehicle through the
Blue Link AVN control unit.
Refer to the Multimedia manual or
the Blue Link manual for detailed
information about setting sched-uled charging.
Scheduled charging can only be done when using a normal charger
or the portable charging cable
(ICCB: In-Cable Control Box).
