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.
Notice
The parking assist system can be
activated and deactivated by
changing the settings in the
Info-Display.
Vehicle personalisation 3 122.
Notice
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.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Notice
After production, the system
requires a calibration. For optimal
parking guidance, a driving distance
of at least 22 miles, including a
number of bends, is required.
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 alerts
visually 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.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, the amber
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
200Driving and operating
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.
If the vehicle is equipped with lane
change alert 3 201, the symbol F
is displayed in the mirrors.The system can be activated or
deactivated in the vehicle
personalisation.

Deactivation is indicated by a message in the Driver Information
Centre (DIC).
Detection zones
The system sensor covers a zone of
approx. 3.5 metres on both sides of
the vehicle. This zone starts at each
exterior mirror and extends rearwards by approx. 3 metres. The height of the
zone is approx. between 0.5 metres
and 2 metres off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to
ignore stationary objects such as
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault Occasional missed alerts can occur
under normal circumstances.
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

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 DIC. Seek the
assistance of a workshop.
Driving and operating201Lane change alertAdditional to the side blind spot alert
3 199, lane change alert recognizes
rapidly approaching vehicles from behind on parallel lanes next to your
vehicle.
If the vehicle is equipped with lane
change alert, side blind spot alert is
always included.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
amber warning symbol F will
illuminate in the relevant exterior
mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing amber as a warning not to change lanes.
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.
Detection zones
The system sensors cover a zone of
approx. 3.5 metres parallel on both
vehicle sides and approx. 3 metres
rearwards on side blind zone alert
(A) and approx. 70 metres rearwards
on lane change alert (B) on parallel
lanes. The zones start at each
exterior mirror. The height of the zone
is approx. between 0.5 metres and
2 metres off the ground.

Notice
After production, the system
requires a calibration. For optimal performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
Fault
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. Otherwise the system may light up due to guardrails, signs,trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.

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 (DIC).
206Driving and operating
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

■ tractor constraints
■ wet warning■ ice warning
■ direction arrows
Speed limit signs and no passing
signs are displayed in the DIC 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
recognised by the system.
The system is active up to a speed of
