WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Even inadvertently filling the fuel tank with another biofuel such as Ethanol°E85
can result in damage to the fuel system.

If you park the car for a lengthy period, fill with petrol complying with (DIN) EN°228,
because Ethanol E85 can contain low quantities of impurities, which can lead to corro-
sion.
For the sake of the environment
If you use Ethanol E85, the CO
Note

When operating with Ethanol E85, the fuel consumption increases by approx 33%,
as a lower quantity of energy is contained in the bioethanol than in unleaded petrol.

Biofuel Ethanol E85 contains only a low quantity of additives in contrast to
unleaded petrol. Therefore we recommend to fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g. before the oil change) and run it empty,
so that the engine remains clean. Make sure not to use the whole content of the tank
 page 195, "Refuelling".

The interval of 15 000 km applies for the oil change.
Using the system Safety

Driving Tips
Operation in winter
If you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat the
engine before an engine start.
The power socket for the engine preheating is located in the front bumper next to the
 fig.
fog light 158.
The outside temperature
lower than -10 °C
lower than -15 °C
lower than -25 °C
If an engine preheating is not possible at outside temperatures lower than -10 °C, the
share of unleaded petrol complying with EN 228 must be as high as possible. Thus the
cold start property of the engine is clearly improved.
If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can lead at
temperatures below -15°C to very poor or no starting of the engine.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on the
fuel consumption and thus on the environment.
