● city regions (country specific)
● motorways
● A-roads
● play streetsAdd on signs ● additional hints to traffic signs
● restriction of trailer towing
● tractor constraints
● wet warning
● ice warning
● time constraints
● distance constraints
● 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.
Indication of multiple signs on the
display is possible.
An exclamation mark in a frame
indicates that there is an additional
sign detected which cannot be clearly
identified by the system.
The system operates without loss of

Driving and operating185detection of a new sign although no
sign on the road might have been
passed.
Fault
Traffic sign assistant may not operate correctly if:
● 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.
● 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 keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings. If the
vehicle approaches a lane marking,
the steering wheel is gently turned to
position the vehicle back into the lane. Override the system by turning the
steering wheel.
Crossing a lane marking significantly
without overriding lane keep assist
starts a visual and acoustic warning.
Unintended lane departure is
assumed
● without using turn signal
● using the turn signal in the opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering.
Notice
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Notice
The system may be switched off, if it detects lanes, which are too narrow,
too wide or too much curved.

Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more tyre pressure sensors were replaced.
The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a relearn tool, in the following order: left side front wheel,
right side front wheel, right side rear
