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 or affected
by foreign items, e.g. stickers.
● 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
214Driving and operatingCaution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full functioning of the LPG system
can only be guaranteed with liquid
gas which complies with the minimum
requirements of DIN EN 589.
Fuel selector
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 approximately
60 seconds (depending on exterior
temperature) and the first firm press
on the accelerator. The status LED
shows the current operating mode.1 off:petrol operation1 flashes:checking conditions
for fuel transition to
liquid gas operation.

message is displayed
in the Driver
Information Centre.
If the fuel tank is empty, the engine
will not start.
The selected fuel mode is stored and
reactivated at the next ignition cycle if conditions allow.
As soon as the liquid gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
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?

Remove the cover.
Vehicle care253The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 281.
3. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 292.For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition. After adjusting tyre
pressure switch on ignition and select
the according setting on the page
Tyre load in the Driver Information
Centre, 3 110.
Temperature dependency The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down tyre will show a decreased value,
which does not indicate an air leak.
254Vehicle careTyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns just about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Select the Tyre pressure monitoring
page under the Info Menu in the
Driver Information Centre 3 110.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 252.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 108.
If
w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 292.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure condition. Check tyre pressure.
Vehicle messages 3 119.
If the tyre pressure must be reduced or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
illuminates. For the further three
wheels the system remains
operational.
Vehicle care255The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced tyre
pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor replace valve core and sealing ring, for clipped
sensor replace complete valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according tyre information label or
tyre pressure chart 3 292, and select
the appropriate setting in the Tyre
loading page under the Settings
menu in the Driver Information Centre 3 110 . This setting is the reference for
the tyre pressure warnings.
The menu Tyre loading only appears
if the vehicle is in a standstill and the parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
12 mph. In this case $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message is
displayed in the Driver Information
Centre.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
272Vehicle careTowing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using a soft damp cloth. If necessary use aweak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible discolourations, especially on light-coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water
or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could
damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
