Important hints for using the
parking assist systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the 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.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Note
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving
distance of at least 10 km, 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.
Page 194 of 321

192Driving and operating9Warning
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.
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 3 193, the symbol F
is displayed in the mirrors.The system can be activated or
deactivated in the vehicle
personalisation.

exterior mirror and extends rearwardsby 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 occurunder 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

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 (DIC). Seek the assistance of
a workshop.Lane change alert
Additional to the side blind spot alert
3 191, 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. Additionally a
warning chime sounds.
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.

The system is deactivated if the
vehicle is towing a trailer.
Deactivation is indicated by a
message in the Driver Information
Centre (DIC).
Note
After use, 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 occurunder normal circumstances and will
increase in wet conditions or in sharp
curves. Otherwise the system maylight 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.
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 more signs in the
display are possible.
An exclamation mark in a frame
indicates that there are additional
signs detected which cannot be
recognised by the system.
The system is active up to a speed of
200 km/h depending on the lighting
conditions. At night the system is
active up to a speed of 160 km/h.
As soon as the speed becomes
slower than 55 km/h 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
Traffic sign detection page in the
Driver Information Centre.
