General information
When the trailer hitch is attached,
change the configuration settings in
the vehicle personalisation menu in
the Info Display. Vehicle
personalisation 3 124.
When attaching a trailer or bike
carrier to the trailer hitch, the parking
assist is deactivated.
Front-rear parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The front-rear parking assist
measures the distance between the
vehicle and obstacles in front and
behind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system has four ultrasonic
parking sensors each in the rear and
front bumper.
Activation
The system is activated automatically
at a speed up to 11 km/h.
226Driving and operating
When searching for a parking slot, the
system is ready to operate with a
short press of (.
The system recognises and
memorises ten metres for parallel
parking slots or six metres for
perpendicular parking slots in the
parking assist mode.
The system can only be activated and searches for a parking slot at a speed
up to 30 km/h.
Advanced parking assist may not be
activated when driving on very steep
inclines.
FunctionalityParking slot searching mode,

parallel parking or five cycles
when perpendicular parking
● switching off the ignition
Deactivation by the driver or by the system during manoeuvring will beindicated by a message on the
display. Additionally, an acoustic
signal sounds.
Automatic transmission:
If advanced park assist is deactivated
during the parking manoeuvre or
manoeuvre is finished successfully,
the assist holds the vehicle in position
until one of the following conditions
occur:
1. brake pedal is applied.
2. electric parking brake is activated.
3. Selector lever is set to P
Fault
A message appears when:
● There is a fault in the system.● The driver did not successfully complete the parking
manoeuvre.● The system is not operational.
● Any of the deactivation reasons described above apply.
If an object is detected during parking instructions, a message to stop the
vehicle is indicated. Removing the
object will resume the parking
manoeuvre. If the object is not
removed, the system will be
deactivated.
Basic notes on 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.
Driving and operating229Caution
Performance of the system can bereduced 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
It is possible that the sensor detects a non-existing object caused by
echo disturbance from external
acoustic noise or mechanical
misalignments (sporadic false
warnings may occur).
Make sure that the front number
plate is properly mounted (not bent
and no gaps to the bumper on the left
or right side) and the sensors are
firmly in place.
Advanced parking assist system
may not respond to changes in the
available parking space after
initiating a parking manoeuvre. The
system may recognize an entry, a
gateway, a courtyard or even a crossing as a parking slot. After
selecting reverse gear the system
will start a parking manoeuvre. Take care regarding the availability of the
suggested parking slot.
Low curbs and surface irregularities,
e.g. on construction zones, are not
detected by the system. The driver
accepts responsibility.
Note
New vehicles require a calibration
during first use. For optimal parking
guidance, a driving distance of at
least 10 km, including a number of
bends, is required.System is calibrated to factory-fitted
wheels. Parking performance is
altered with other tyre or wheels
sizes.
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.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.
230Driving and operating
When the vehicle is started, both
exterior mirror displays will briefly illuminate to indicate that the system
is operating.
When the system detects a moving
vehicle in the side blind spot while
driving forwards, either while passing a vehicle or being passed, a yellow
warning symbol F will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol F starts
flashing yellow as a warning not to
change lanes.
Side blind spot alert is active at any
speed.
Deactivation
Activation or deactivation of the Side
blind zone alert can be set in the
vehicle personalisation menu in the
Info-Display.
Vehicle personalisation 3 124.
Info-Display 3 118.
Deactivation is indicated by a
message in the Driver Information
Centre.
System limitations Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to a wet area can cause the control
indicator F to light up, as water
splash can be interpreted as an object. Otherwise the control indicator
F may illuminate due to guardrails,
signs, trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.The system may not operate properly
when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms.
● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailer
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.
Note
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.
Driving and operating231Lane change alertAdditional to the side blind spot alert
3 229, lane change alert recognizes
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
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
yellow warning symbol F will
illuminate in the relevant exterior mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing yellow as a warning not to change lanes.
Lane change alert is active at all
speeds.
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. 50 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.
Deactivation
Activation or deactivation of the lane
change alert can be set in the vehicle personalisation menu in the Info-
Display.
240Driving and operatingAlert 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

selecting Reset and confirm by
Driving and operating241pressing SET/CLR on the turn signal
lever or 9 on the steering wheel
controls.
Alternatively, SET/CLR or 9 can be
pressed for three seconds to clear the
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 or provided by map
data of the navigation system.
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” or a sign from
navigation map data 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
● If no navigation map data is available and speed drops below52 km/h (city entry detection)
● If navigation map data is available and a city entry/exit was
detected due to map data change
Traffic sign detection in
conjunction with navigation
system
If the vehicle is equipped with a
navigation system, the currently
displayed sign can either originate
from optical sign detection or from the
map data.
If the currently displayed sign
originates from map data and the map
information changes, a new sign will
be displayed. This may lead to
detection of a new sign although no
sign on the road may have been
passed.System limitations
Traffic sign assistant may not operate properly when:
● Vehicle speed is faster than 200 km/h.
● Driving on winding or hilly roads.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
