Fault
Fault messages are displayed with a 9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
■ the surrounding is dark
■ the sun or the beam of headlights is
shining directly into the camera
lens
■ ice, snow, mud, or anything else covers the camera lens. Clean the
lens, rinse it with water, and wipe it
with a soft cloth

■ there are extreme temperature changesTraffic 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
■ tractor constraints
■ wet warning
■ ice warning
■ direction arrows
Speed limit signs and no passing
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.

Driving and operating165
Combinations of multiple signs in the
display are possible.
An 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.
As soon as the 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 indication
Traffic signs are displayed on the
page Traffic sign detection on the
Driver Information Centre. Choose
Vehicle by the Menu button and
select Traffic sign detection entry via
the adjuster wheel on the turn signal lever 3 93.
When another page on the Driver
Information Centre menu was
selected and then Traffic sign
detection page is chosen again, the
last recognised traffic sign will be
displayed.
Alert function
Once activated, speed limit and no
passing signs are displayed as pop-
up alerts in the Driver Information
Centre.

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 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.
Lane departure warning
The lane departure warning systemobserves 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
via 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 performing these
actions, no warning will be issued.
Activation
The lane departure warning system is activated by pressing the ) button.
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.

The menu can be selected by the
buttons on the turn signal lever.
Press the MENU button to select the
Vehicle Menu .
Turn the adjuster wheel to select the
tyre pressure monitoring system.
Baselevel display and Midlevel
display:
The tyre pressure for each tyre is
displayed on its own page.
Uplevel display:
The tyre pressures for all tyres are
displayed on one page.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in the DIC.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 91.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 237.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
Page 204 of 249

202Vehicle care
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for getting low
pressure. Check tyre pressure.
Vehicle messages 3 100.
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 tyres. Control indicator w
illuminates. For the further three tyres
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.
External high-power radio equipment
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 the
clipped sensor; replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according tyre information label or
tyre pressure chart 3 237, and select
the according setting in the menu Tire
