Traffic sign detection in
conjunction with navigation
system If the vehicle is equipped with a
navigation system, the following
features can be available:
■ constant indication of actual speed limits
■ on heavy weather conditions, the navigation data for speed limits aredisplayed
Fault
The traffic sign assistant system may
not operate correctly when:
■ The area of the windscreen, where the front camera is located, is not
clean.
■ Traffic signs are completely or partially covered or difficult to
discern.
■ There are adverse environmental conditions, e.g. heavy rain, snow,
direct sunlight or shadows. In this

event, No Traffic Sign Detection
due to Weather is indicated on the
display.
■ Traffic signs are incorrectly mounted or damaged.
■ Traffic signs do not comply with the
Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to recognise certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not recognise
any other than the conventional
traffic signs that might give or end
a speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving, via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
by visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ No operation of turn signals.
■ No brake pedal operation.
■ No active accelerator operation or speeding-up.
■ No active steering.
If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When the control indicator ) in
the instrument cluster illuminates
green, the system is ready to operate.
The system is only operable at
vehicle speeds above 35 mph and if
lane markings are available.
Page 212 of 331

210Driving and operating
When the system recognises an
unintended lane change, the control indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ); the LED in the button
extinguishes.
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, e.g. heavy rain, snow,
direct sunlight or shadows.
The system cannot operate when no
lane marking is detected.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 279. 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.
Page 213 of 331

Driving and operating211Caution
Use of fuel that does not comply toEN 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
sulfur concentration below 50 ppm.
Caution
Use of fuel that does not comply to EN 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.

212Driving and operating
Press LPG to switch 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 tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator i or Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. If possible, close the
manual shut-off valve on the
multivalve. The multivalve is located
on the liquid gas tank in the load
compartment, underneath the rear
floor cover.
Page 215 of 331

Driving and operating213
Turn the thumb wheel clockwise.
If no further gas odour is perceptible
when the manual shut-off valve is
closed, the vehicle can be used in
petrol mode. If the gas odour persists, do not start the engine. Have the
cause of the fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights. Close the
manual shut-off valve on multivalve.
Refuelling9 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.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of vehicle.
Page 216 of 331
214Driving and operating
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
Petrol and Diesel refuelling
To open, turn the cap slowly
anticlockwise.The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After the automatic cut-off, the tank can be topped-up with a maximum
two doses of fuel.
Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and let engage.
Vehicles with misfuel inhibitor9 Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
