166Infotainment systemNavigationGeneral information
The navigation system will reliably
guide you to your destination.
The current traffic situation is taken
into account in the route calculation.
For this purpose, the Infotainment
system receives traffic
announcements in the current
reception area via RDS-TMC.
The navigation system cannot,
however, take into account traffic
incidents, traffic regulations changed
at short notice and hazards or
problems that arise suddenly (e.g.
road works).Caution
The usage of the navigation
system does not release the driver
from the responsibility for a
correct, vigilant attitude in road
traffic. The relevant traffic
regulations must always be
followed. If a navigation instruction contradicts traffic regulations, the
traffic regulations always apply.
Functioning of the navigation
system
The position and movement of the
vehicle are detected by the navigation
system using sensors. The travelled
distance is determined by the
vehicle’s speedometer signal, turning
movements on bends by a sensor.
The position is determined by the GPS (Global Positioning System)
satellites.
By comparing the sensor signals with the digital maps, it is possible to
determine the position with an
accuracy of approx. 10 metres.
The system will also work with poor
GPS reception. However, the
accuracy of the determination of the
position will be reduced.
After the entry of the destination
address or point of interest (nearest
petrol station, hotel, etc.), the route is calculated from the current location to
the destination selected.
Route guidance is provided by voice
output and an arrow, as well as with
the aid of a multi-colour map display.
Important information
TMC traffic information system and
dynamic route guidance
The TMC traffic information system
receives all current traffic information from TMC radio stations. This
information is included in the
calculation of the overall route. During
this process, the route is planned so
that traffic problems related to pre-
selected criteria are avoided.
If there is a traffic problem during
active route guidance, depending on
the pre-settings, a message appears
as to whether the route should be
changed.
TMC traffic information is displayed in
the map display as symbols or as
detailed text on the TMC messages
menu.
To be able to use TMC traffic
information, the system must receive
TMC stations in the relevant region.
Driving and operating233Driver Information Centre and a
warning chime sounds. Depress the
brake pedal, if it is required by the
situation.
Deactivation
The system can be deactivated.
Press V repeatedly until Forward
Collision Alert Off appears in the
Driver Information Centre.
General information for both
variants of forward collision alert9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also onother metallic objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance indication
The following distance indication
displays the distance to a preceding
moving vehicle. The system uses,
depending on the vehicle equipment,
either the radar behind the radiator
grille or the front camera in the
windscreen to detect the distance of
a vehicle directly ahead in your path.
It is active at speeds above 40 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 117.
Press MENU on the turn signal lever
to select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 s.
238Driving and operatingexternal noise sources may causethe system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
It is possible that the sensor detects a non-existing object (echo
disturbance) caused by external acoustical or mechanic
disturbances.
Note
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse gear first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r briefly to
deactivate the parking assist.
Side blind spot alert
The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system
displays a visual alert in each exterior
mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
Driving and operating239When the system detects a vehicle in
the side blind zone while driving
forward, either while passing a
vehicle or being passed, a yellow
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
yellow as a warning not to change
lanes.
Note
If the passing vehicle is at least
10 km/h faster than the passed
vehicle, the warning symbol B in the
relevant exterior mirror may not
illuminate.Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
illuminate to indicate that the system
is operating.
The system can be activated or
deactivated in the Info-Display,
vehicle personalisation 3 124.
The system is deactivated if the
vehicle is towing a trailer.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The detection zones start at the rear
bumper and extend approx.
three metres rearwards and to thesides. The height of the zone is
approx. between half a metre and two metres off the ground.
Side blind spot alert is designed to
ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions
3 300.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop in case of a permanent
fault.
Driving and operating243
Choose ? via MENU and select
traffic sign assistant page with the adjuster wheel on the turn signal lever
3 117.
When another page on the Driver
Information Centre menu was
selected and then traffic sign
assistant page is chosen again, the
last recognised traffic sign will be
displayed.
Alert function
The alert function can be activated or
deactivated in the setting menu of the
traffic sign assistant page.Once activated and when the traffic
sign detection page is currently not
displayed, newly detected speed limit and no passing signs are displayed
as popup alerts in the Driver
Information Centre.
When traffic sign assistant page is
displayed, press SET/CLR on the turn
signal lever.
244Driving and operating
Select Alerts ON or Alerts OFF by
turning the adjuster wheel and press

content of the page.
Upon successful reset, a chime will
sound and the following “Default
Sign” is indicated until the next traffic
sign is detected.
In some cases, traffic sign assistant is
cleared up automatically by the
system.
Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” is displayed in the
Driver Information Centre.
Reasons for signs being cleared:
● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● The speed becomes slower than 52 km/h (city entry detection)
Fault
The traffic sign assistant system 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).
Driving and operating245Caution
The system is intended to help thedriver 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 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
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 active, no warning will
be issued.
ActivationThe lane departure warning system isactivated 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 56 km/h and if
lane markings are available.
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 56 km/h the system
is inoperable.
