Traffic sign assistant
Functionality The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the
Driver Information Centre.Traffic signs which will be detected
are:Limit and no passing signs ● speed limit
● no passing
● end of speed limit
● end of no passingRoad signs
beginning and end of:
● motorways
● A-roads
● play streetsAdd-on signs ● additional hints to traffic signs
● restriction of trailer towing
● wet warning
● ice warning
● direction arrows
Speed limit signs are displayed in the
Driver Information Centre until the
next speed limit sign or end of speed
limit is detected or up to a defined sign timeout.
Combinations of multiple signs in the
display are possible.
Driving and operating205An exclamation mark in a frame
indicates that there is an additional
sign detected which cannot be
recognised by the system.
The system is active up to a speed of
124 mph depending on the lighting
conditions. At night the system is
active up to a speed of 99 mph.
As soon as vehicle speed becomes
slower than 34 mph the display will be
reset and the content of the traffic sign page will be cleared, e.g. when
entering a city zone. The next
recognized speed indication will be
displayed.
Display indicationTraffic signs are displayed on the
page Traffic sign detection in the
Driver Information Centre, chosen via the adjuster wheel on the turn signal
lever 3 116.
When another function in the Driver Information Centre menu was
selected and then Traffic sign
detection page is chosen again, the
last recognised traffic sign will be
displayed.
After the traffic sign page is cleared
by the system, the following symbol is
indicated:The content of the traffic sign page is also cleared during driving by
pressing and holding SET/CLR on the
turn signal lever.
Pop-up function
Speed limits and no passing signs are
displayed as pop-ups on each page
of the Driver Information Centre.
206Driving and operating
The pop-up function can be
deactivated on the traffic sign page by
pressing SET/CLR on the turn signal
lever.
Once the Settings page is displayed,
select Off to deactivate pop-up
function. Reactivated by selecting

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
case No Traffic Sign Detection
due to Weather is indicated in the
Driver Information Centre.● 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 discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern 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.
210Driving and operatingLPG 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 LPG 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.

message is displayed
in the Driver
Information Centre.
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.
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.
248Vehicle care
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
The system considers the tyre
temperature for the warnings.A detected low tyre pressure
condition is indicated by control
indicator w 3 114.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 288.
If w flashes for 60-90 seconds and
then illuminates continuously, there is a fault in the system. Consult a
workshop.
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 3 122.
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 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.
The 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.
250Vehicle care3. Press MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should display.
6. Press SET/CLR again to confirm
the selection. The horn sounds
twice to signal the receiver is in
relearn mode.
7. Start with the left side front wheel.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activatethe TPMS sensor. A horn chirp
confirms that the sensor
identification code has been
matched to this wheel position.
9. Proceed to the right side front wheel, and repeat the procedure
in Step 8.
10. Proceed to the right side rear wheel, and repeat the procedure
in Step 8.11. Proceed to the left side rear wheel, and repeat the procedure
in Step 8. The horn sounds twice
to indicate the sensor
identification code has been
matched to the left side rear tyre,
and the TPMS sensor matching
process is no longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
3 116.
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 10 kPa for a10 °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.
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.
266Vehicle careAfter the underbody is washed, checkthe underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Rear carrier system Clean the rear carrier system with a
steam-jet or high-pressure jet cleaner
at least once a year.
Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Air shutter Clean the shutter system in the front
bumper to maintain correct
functionality.
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
belts or studded jeans.
