SAFETY PRECAUTIONS

Make sure that the following warnings have been read and understood. Failure to observe the warnings could result in an accident, leading to serious injury or death.

WARNING

Do not smoke, use an exposed flame, or cause sparks while refueling.
Avoid exposing the fuel gases to any potential sources of ignition.
Switch off the engine when refueling, as it is both a source of extreme temperature and electrical sparks.
When refueling, switch off any personal electronic devices such as cell phones or music players.
Take note of all warnings and instructions given on the label affixed to the inside of the fuel filler flap.
The fuel system is designed to make sure that spillage does not occur. Do not attempt to fill the tank past its maximum capacity.
Make sure that the fuel filler nozzle is fully inserted into the filler neck. If the nozzle is inserted loosely, fuel spillage may occur.
When refueling, make sure that all of the windows, doors and panoramic roof are fully closed. Use extreme care and caution if young children or animals are in the vehicle.
Only use containers specifically designed for carrying fuel, and always remove them from the vehicle to fill them.

GASOLINE ENGINED VEHICLES

CAUTION
Use high-quality fuel with detergent. Low-quality fuel can damage the engine and reduce engine performance.

CAUTION
Do not use leaded fuels, fuels with lead substitutes, e.g., manganese-based, or fuel additives. The vehicle’s emission control systems can be adversely affected, which may affect the vehicle’s warranty coverage.

CAUTION
Fuel system cleaning agents should not be used unless approved by the vehicle manufacturer. Inadequate cleaning agents may damage the fuel system.

OCTANE RATING

CAUTION
Do not use fuels with an octane rating lower than 87 AKI as severe engine damage may occur.

CAUTION
Do not use leaded fuels, fuels with lead substitutes, e.g., manganese-based or fuel additives. Doing so may adversely affect the vehicle’s emission control systems and affect the vehicle’s warranty.

The vehicle manufacturer recommends the use of premium unleaded gasoline with a minimum octane rating of 91 AKI (Anti-Knock Index). Using the correct fuel specification helps to maintain the vehicle’s performance, fuel economy, and driveability.

If premium unleaded fuel is not available, use unleaded fuel with a lower octane rating, down to a minimum of 87 AKI. Using a lower specification fuel may reduce the vehicle’s performance, increase fuel consumption, cause an audible engine knock, and other driveability problems.

Consult a retailer/authorized repairer if an engine knock is detected while holding a steady speed on level roads. Also consult a retailer/authorized repairer if a heavy persistent engine knock is detected, even if using fuel to the recommended octane rating. Failure to do so is misuse of the vehicle which is not covered by the vehicle’s warranty.

NOTES
An occasional, light engine knock when accelerating or climbing hills is acceptable.

NOTES
Federal law requires that gasoline octane ratings be posted on the pumps.

ETHANOL

CAUTION
Do not use fuels containing more than 15% ethanol. Inadequate fuel can reduce engine performance and may cause damage to engine components.

CAUTION
Do not use E85 fuels with 85% ethanol content, as serious engine and fuel system damage will occur.

Fuels containing up to 15% ethanol may be used, e.g., E10 and E15.

Make sure that the fuel has octane ratings no lower than those recommended for unleaded fuel. Most drivers do not notice any operating difference with fuel containing ethanol. If driveability issues are experienced, revert to using fuel containing no more than 10% ethanol. If the issues remain, use premium quality unleaded fuel instead.

METHYL TERTIARY BUTYL ETHER (MTBE)

Unleaded fuel containing an oxygenate known as Methyl Tertiary Butyl Ether (MTBE) can be used. The ratio of MTBE to conventional fuel must not exceed 15%. MTBE is an ether-based compound derived from gasoline. MTBE has been specified by several refiners as a substance to enhance the octane rating of the fuel.

REFORMULATED GASOLINE

Reformulated gasoline is specially formulated to help further reduce the vehicle’s exhaust emissions. The vehicle manufacturer fully supports all efforts to protect and maintain the ambient air quality, and encourages the use of reformulated gasoline, where available.

RUNNING OUT OF FUEL

CAUTION
Avoid running out of fuel. Doing so can cause damage to the vehicle’s engine, fuel and emission control systems.

If the vehicle does run out of fuel, a minimum of 1.1 U.S. gallons (4 L) is required to restart the engine. The vehicle should be left with the ignition on for 5 minutes after refueling, before attempting to restart the engine. The vehicle needs to be driven 1 – 3 miles (1.6 – 5 km), in order to reset the engine management and monitoring systems.

NOTES
If the vehicle does run out of fuel, seeking qualified assistance is advisable.

FUEL FILLER FLAP

WARNING

Make sure the relevant safety warnings have been read and understood before refueling the vehicle. See SAFETY PRECAUTIONS.

The fuel filler flap is located on the right side of the vehicle, at the rear. To operate, proceed as follows:

Press and release the rear of the fuel filler flap to unlatch.
Pull the flap open. The label on the inside of the flap indicates the correct fuel for the vehicle.
Turn the filler cap counter-clockwise to undo.
Use the retaining clip to keep the filler cap out of the way while fueling.

When replacing the filler cap, turn it clockwise until the ratchet clicks.

To close the filler flap, push the flap until it is securely latched.

FUEL FILLER

WARNING
Make sure the relevant safety warnings have been read and understood before refueling the vehicle. See SAFETY PRECAUTIONS.

CAUTION
Check the fuel pump information carefully, to make sure that the correct fuel is used to refuel the vehicle. Inadequate fuel can reduce engine performance and may cause permanent damage to engine components.

CAUTION
If the vehicle is filled with incorrect fuel, it is essential to seek qualified assistance before starting the engine. Inadequate fuel can reduce engine performance and may cause permanent damage to engine components.

Filling station pumps are equipped with automatic cut-off sensing to avoid fuel spillage. Fill the tank until the filler nozzle automatically cuts off the supply. Do not attempt to fill the tank beyond this point.

FUEL TANK CAPACITY

Avoid the risk of running out of fuel. Never intentionally drive the vehicle when the fuel gauge indicates that the tank is empty. When refueling the vehicle after the indicated range reads zero, it may not be possible to add the maximum fuel quantity. The fuel tank retains a small reserve of fuel. See CAPACITIES.
