OCTANE RATING

CAUTION

Do not use fuels with an octane rating lower than 91 RON, 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 fuel with a minimum octane rating of 95 RON. 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 91 RON. Using lower octane-rated fuel may reduce the engine's performance, increase fuel consumption, cause an audible engine knock, and cause other driveability problems.

Consult a retailer/authorised repairer if an engine knock is detected while holding a steady speed on level roads. Also consult a retailer/authorised 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.

Super Green Plus 98 RON unleaded fuel, where available, may be used as an alternative to the standard 95 RON unleaded fuel.
