Operation Manual

Driving and operating 137
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
Fuel for ethanol adapted
engines (E85)
If access to E85 is limited then fuel
with a different proportion of ethanol
or normal RON 95 can be used for
refuelling. The engine's control
management system is adjusted
automatically according to the
amount of ethanol in the fuel.
E85 fuel must fulfil the CWA 15293 or
SS 155480 standard.
When the temperature is about
-10 °C or lower a greater proportion of
petrol should be used. E85 in
combination with low temperatures
could lead to the car being more
difficult to start. A slightly higher
proportion of petrol improves the cold
start properties considerably.
During the engine's warm-up phase
(below +50 °C) engine torque is
limited when driving with a proportion
of ethanol.
Ethanol contains less energy per litre
than petrol, which is why fuel
consumption increases when driving
on E85 compared with petrol. A
consequence of this is that a tank of
E85 covers fewer miles than a tank of
petrol.
Caution
Certain additives in petrol could, in
combination with ethanol, cause
reduced driveability. For this
reason, refuel with a full tank of
petrol every 6000 miles. Use up
the majority of this before
refuelling the car again.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply
with EN 590 or similar can lead to
engine power loss, increased
wear or engine damage and loss
of warranty.
Do not use marine diesel oils, heating
oils or entirely or partially plant-based
diesel fuels, such as rape seed oil or
bio diesel, Aquazole and similar
diesel-water emulsions. Diesel fuels
must not be diluted with fuels for
petrol engines.
Refuelling
9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
