Use Active Parking Assist for parking spaces:
R
that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same
level as the road, e.g.
not on the pavement
Parking tips:
R On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 182) warning messages during the
parking procedure.
R You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergency spare
wheel are mounted, you should not use
Active Parking Assist here either.
R Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or
loading
ramps of goods
vehicles. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely. You may cause a collision as a result. There is
a risk of an accident.
If there are objects
above
the detection range,
stop and deactivate Active Parking Assist.
Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. When driving at speeds below
19 mph (30 km/h), you will see the parking
symbol as a status indicator in the instrument
cluster. By default, Active Parking Assist only
displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. To park
on the driver's side, you must leave the
driver's side turn signal switched on. This
must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the 0076 button on the
multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. Example: detected parking space
0043

0087 Detected parking space on the right
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than
your vehicle Driving systems

Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and
behind it
and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
R You can also engage forward gear
prematurely. The vehicle redirects and
does not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A
sensible parking position can no longer be
achieved from this position.
Exiting a parking space In order that Active Parking Assist can
support you when you
exit
the parking space:
R the border of the parking space must not
be too low.
R the border of the parking space must not
be too wide. The system maneuvers the
vehicle into a position at a maximum of 45°
to the starting position in the parking
space.
R a maneuvering distance of at least 24 in
(0.60 m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle using Active Parking Assist.

Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in
time
or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the
surface is uneven or if there are potholes
R if there is a strong side wind Driving systems

Detected message appears in the
multifunction display.
X If necessary, take a break.
X Press the 0076 button to confirm the
message.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break,
you will be warned again
after 15 minutes at the earliest. The
precondition for this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration. ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness again if:
R
you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a
change of drivers or
to take a break. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 198) and Lane Keeping
Assist (
Y
page 200).
Blind Spot Assist General notes
Blind Spot Assist uses
a
radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
For Blind Spot Assist to assist you when
driving, the radar sensor system must be:
R activated(Y page 229)
R operational
Important safety notes
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles. 198

WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles being overtaken at a speed
difference of more than 7.5 mph
(12 km/h )
R vehicles which approach with
a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
i USA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or
bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to
10 ft (3m) behind your vehicle and directly
next to your vehicle,
as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if there are vehicles driving at the
inner edge of their lanes.
Due to the nature of the system:
R warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly. Driving systems
