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.
FUEL REQUIREMENTS

Foreword/Starting your Hybrid/Plug-in hybrid vehicle1-6
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
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.
Detergent Fuel Additives
HYUNDAI recommends that you use good quality gasolines treated with detergent
additives such as TOP TIER Detergent Gasoline, which help prevent deposit formation
in the engine. These gasolines will help the engine run cleaner and enha\
nce
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, detergent-based fuel additives
that you can purchase separately may be added to the gasoline. If TOP TIER Detergent
Gasoline is not available, one bottle of additive added to the fuel tank according to the
maintenance schedule is recommended (refer to the Maintenance Schedule in chapter
9).
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.

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.

HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the
electric motor for power. The electric 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 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.
