Driving and operating209
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system
may not operate properly when:
■ the windscreen is not clean
■ there are adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows
The system can not operate when no
lane marking is detected.Fuel
Fuel for petrol enginesOnly use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable to run with
E10 fuel that fulfills these standards.
E10 fuel contains up to 10 %
bioethanol.
Use fuel with the recommended
octane rating 3 291. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled combustion and engine damage.
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.

210Driving and operatingCaution
Use of fuel that does not comply toEN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for liquid gas
operation
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after around 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator i
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
