WARNINGS:
Do not modify the fuel system configuration or the components in the system.
Do not replace the fuel system or the components with parts not specially designed to be used with E85.
CAUTIONS:
Do not use leaded petrol or petrol with additives containing other metallic compounds (e.g.
manganese-based). They could damage the emission system.
Do not use methanol instead of E85.
Note: We recommend that you use only high quality fuel without additives or other engine treatments.
Note: When using E85, you may experience a higher fuel consumption.
Note: Your vehicle will operate well on commercial quality 95 octane unleaded petrol, but only high quality E85 offers the same protection and performance.
Use minimum 95 octane unleaded petrol that meets the specification defined by EN 228, or equivalent. You can also use a mixture of unleaded petrol and E85.
Long-term storage
Due to small amounts of corrosive impurities that may be found in the E85, it is recommended that you fill the tank with only 95 octane unleaded petrol prior to long-term storage of your vehicle.
