Unleaded
Your new vehicle is designed to perform optimally with 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.

VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its performance, safety or durability and may even violate governmental safety and
emissions regulations.
In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate abnormally, wire damage, battery discharge and fire. For your safety, do not use
unauthorized electronic devices.
NOTICE
Some warning sounds (including welcome/good-bye sound, etc.) are generated
from the interior speakers or amplifiers. If necessary, purchase HYUNDAI Part to
replace an interior speaker or amplifier. Any unauthorized product may cause a
malfunction of the interior speakers or amplifiers.
VEHICLE BREAK-IN PROCESS
By following a few simple precautions for the first 600 miles (1,000 km) you may add to
the performance, economy and life of your vehicle.
• Do not race the engine.
• While driving, avoid sudden acceleration.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
• Fuel economy and engine performance may vary depending on vehicle break-in process and be stabilized after 4,000 miles (6,000 km). New engines may consume
more oil during the vehicle break-in period.
• Do not tow a trailer during the first 1,200 miles (2,000km) of operation.

Actual charger image and charging
method may vary in accordance with the
charger manufacturer.
WARNING
• Electromagnetic waves that are
generated from the charger can
seriously impact medical electric
devices such as an implantable
cardiac pacemaker.
When using medical electric devices
such as an implantable cardiac
pacemaker, make sure to ask the
medical team and manufacturer
whether charging your electric
vehicle will impact the operation of
the medical electric devices such as
an implantable cardiac pacemaker.
• Check to make sure there is no
water or dust on the charging
cable connector and plug before
connecting to the charger and
charging inlet. Connecting while
there is water or dust on the charging
cable connector and plug may cause
a fire or electric shock.
• Be careful not to touch the charging
connector, charging plug, and the
charging inlet when connecting
the cable to the charger and the
charging inlet on the vehicle. •
Comply with the following in order
to prevent electrical shock when
charging:
- Use a waterproof charger.
- Be careful when touching the
charging connector and charging
plug with your hands wet, or when
standing in water or snow while
connecting the charging cable.
- Be careful when there is lightning.
- Be careful when the charging
connector and plug is wet.
• Immediately stop charging when
you find abnormal symptoms (odor,
smoke).
• Replace the charging cable if the
cable coating is damaged to prevent
electrical shock.
• When connecting or removing the
charging cable, make sure to hold
the charging connector handle and
charging plug.
If you pull the cable itself (without
using the handle), the internal wires
may disconnect or get damaged. This
may lead to electric shock or fire.
