Unleaded
Your new vehicle is designed to perform optimally using 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 / Hybrid System Overview1-6
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.

WARNING
If a fire occurs:

[ If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires.
If it is impossible to extinguish
the fire in the early stage, remain
a safe distance from the vehicle
and immediately call your local
fire emergency responders. Also,
advise them that a hybrid vehicle is
involved.
If the fire spreads to the high voltage
battery, large amount of water is
needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.

[ Upon witnessing any sparks, gases,
flames, or fuel leakage of your
vehicle, immediately call emergency
services or contact an authorized
HYUNDAI dealer. Also, advise them
that a hybrid vehicle is involved.
WARNING
When a submersion in water occurs:
When your vehicle is flooded in water, a
high-voltage battery may cause shock
or fires. Thus, turn the hybrid system
OFF, take the key in your possession and
escape to a safe place. Never attempt
physical contact with your flooded
vehicle.
Immediately contact an authorized
HYUNDAI dealer and advise them that a
hybrid vehicle is involved.
When the Hybrid Vehicle Shuts
Off
When the high voltage battery or 12 volt
battery is discharged, or when the fuel
tank is empty, the hybrid system may
not operate while driving. When the
Hybrid system does not operate, do the
following:
1. Gradually reduce the vehicle speed.
Pull over your vehicle off the road in a
safe area.
2. Make sure the shift button is in P (Park).
3. Turn ON the hazard warning flashers.
4. Turn OFF the vehicle, and try to start the hybrid system again, while
depressing the brake pedal and
turning on the ignition switch.
5. When the hybrid system still does not operate, refer to “Jump starting”
section in chapter 8.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to “Jump starting”
section in chapter 8. When the fuel
level is low, do not attempt to drive
the vehicle only with the battery
power. The high voltage battery may
be discharged, and the hybrid system
will turn OFF.

Recommended SAE Viscosity Number
CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.
