Gasoline containing alcohol or
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
15% 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.
Using Fuel Additives (except
Detergent Fuel Additives)
Using fuel additives such as:
- Silicone fuel additive
-Ferrocene (iron-based) fuel additive
-Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, damage
to the catalyst, or abnormal corrosion,
and may cause damage to the engine
resulting in a reduction in the overall life
of the powertrain.
- The Malfunction Indicator Lamp (MIL)
may illuminate.
NOTICE
Damage to the fuel system or
performance problem caused by the
use of these fuels or fuel additives may
not be covered by your New Vehicle
Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives such
as MMT (Methylcyclopentadienyl
Manganese Tricarbonyl).
HYUNDAI does not recommend the use
of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emission
control system.
The malfunction indicator lamp on the
cluster may come on.

VEHICLE DATA COLLECTION
AND EVENT DATA
RECORDERS
This vehicle is equipped with an event
data recorder (EDR). The main 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 systems for a short period of
time, typically 30 seconds or less. The
EDR in this vehicle is designed to record
such data as:
• How various systems in your vehicle
were operating;
• Whether or not the driver and
passenger safety belts were buckled/
fastened;
• How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data is recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
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 combine the
EDR data with the type of personally
identifying data routinely acquired
during a crash investigation.
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.

Hybrid System Gauge
Power gauge
„„Type A, B
OCN7H040006
„„Type C
OCN7H040002
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 driven
using the gasoline engine.
Hybrid battery SOC (State of Charge)
gauge
„„Type A, B
OCN7H040007
„„Type C

This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “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 “L (Low)” level, we recommend the
vehicle be checked by an authorized
HYUNDAI dealer.

Seat Warmers (if equipped)
Front seat warmers
Seat warmers are provided to warm the
seats during cold weather.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of
time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers:
• Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:
• Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Do not place heavy or sharp objects
on seats equipped with seat warmers.
• Do not change the seat cover. It
may damage the seat warmer or air
ventilation system.

NOTICE
Never try to start the vehicle if the fuel
tank is empty. In this condition, the
engine cannot charge the high voltage
battery of the hybrid system. If you
try to start the vehicle when the fuel
is empty, the high voltage battery will
become discharged and be damaged.

• When refueling, always move the
shift lever to the P (Park) position,
set the parking brake, and place the
ignition switch to the LOCK/OFF
position.
• Sparks produced by electrical
components related to the engine
can ignite fuel vapors causing a fire.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire. Once refueling
has begun, contact between your
bare hand and the vehicle should
be maintained until the filling is
complete.
• Use only approved portable plastic
fuel containers designed to carry and
store gasoline.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.• If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” suggested in
the Introduction chapter.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces may
damage the paint.
• If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can result
in a serious malfunction of the fuel
system or emission control system.
