Unleaded
Your new vehicle is designed to use only 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.

Information

[ The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux. Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function will
stop activating, judging that there is
a problem with the auxiliary battery.
In this case, drive the vehicle for some
period of time. The function will start activating if the auxiliary battery
returns to normal.

[ The Aux. Battery Saver+ function
cannot prevent battery discharge if the auxiliary battery is damaged, worn out,
used as a power supply or unauthorized
electronic devices are used.

[ If the Aux. Battery Saver+ function was activated, the high voltage battery level
may have decreased.
System Setting
OAEPHQ049855L
The driver can activate the Aux. Battery
Saver+ function by placing the ignition
switch to the ON position and by selecting:

8VHU6HWWLQJV
Ÿ2WKHU
Ÿ$X[%DWWHU\
Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels the
system setting.
WARNING
OTMPHQ010017L
When the function is activating the
charging indicator lamp will quickly
blink and high voltage electricity will
be flowing in the vehicle. Do not touch
the high voltage electric wire (orange),
connector, and all electric components
and devices. This may cause electric
shock and lead to injuries. Also, do not
modify your vehicle in any way. This
may affect your vehicle performance
and lead to an accident.

or sudden stop, the unlocked seatback
could allow cargo to move forward with
great force and enter the passenger
compartment, which could result in
serious injury or death.

since they cannot be properly secured
and may hit vehicle occupants in a
collision causing serious injury or death.
WARNING
Make sure the engine is off, the gear
shifted to P (Park), and the parking
brake is securely applied whenever
loading or unloading cargo. Failure
to take these steps may allow the
vehicle to move if the shift button
is inadvertently pressed to another position.
CAUTION

[ Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.

[ When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.

This section describes how to use the
seat belts properly. It also describes
some of the things not to do when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
not a replacement. Most countries
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts:
[ Children under the age of 13 should
be properly restrained in the rear
seats.

[ Never allow children to ride in the
front passenger seat, unless the air
bag is deactivated. If a child is seated
in the front passenger seat, move
the seat as far back as possible and
properly restrain them in the seat.

[ NEVER allow an infant or child to be
carried on an occupant’s lap.

[ NEVER ride with the seatback
reclined when the vehicle is moving.

[ Do not allow children to share a seat
or seat belt.

[ Do not wear the shoulder belt under
your arm or behind your back.
[
NEVER wear a seat belt over fragile
objects. If there is a sudden stop or
impact, the seat belt can damage it.

[ Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.

[ Do not use a seat belt if the webbing
or hardware is damaged.

[ Do not latch the seat belt into the
buckles of other seats.

[ NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an accident.

[ Make sure there is nothing in the
buckle interfering with the seat belt
latch mechanism. This may prevent
the seat belt from fastening securely.

[ No modifications or additions
should be made by the user which
will either prohibit the seat belt
adjusting devices from operating to
remove slack, or prohibit the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace:
[ Frayed, contaminated, or damaged
webbing.

[ Damaged hardware.

[ The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent.
