WARNING
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle .Otherwise, you may damage
the wheels or tyres.
Active Parking Assist is an electroni cparking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the
parking symbol. Active steering intervention
can assis tyou during parking. You may also
use PARKTRONIC (Y page 191). When PARK-
TRONIC is switched off, Active Parking Assist
is also unavailable.
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 closely as possi-
ble past the parking space.
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 193) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled.
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 fitted, you should not use Active
Parking Assist here either.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion 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 kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be cancelled. Driving systems

Detecting parking spaces
Example: detected parking space
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assis tisswitched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of th evehicle. When
driving at speeds below 30 km/h, you will see
the parking symbol as a status indicator in the
instrumen tcluster .Active Parking Assist only
displays parking spaces on the front-
passenger side as standard .Parking spaces
on the driver's side are displayed as soon as
the tur nsignal on the driver's side is activa-
ted. To park on the driver's side, you must
leave the driver's side tur nsignal switched
on. This must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the abutton on the multi-
function steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears.
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 m longer than your
vehicle
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it. Parking G
WARNING
PARKTRONIC and Active Parking Assist are
merely parking aids and may no tdetec tall
obstacles. They do not relieve you of the
responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could, otherwise, endanger
yourself and others. G
WARNING
When parking, you need to make sure that no
obstacles are located in the vicinity of the
vehicle during the entire operation. Active
Parking Assist does not relieve you of the
responsibility of paying attention. It merely
aids you by intervening actively in the steer-
ing.

General notes Lane Keeping Assist monitors the area in
front of your vehicle by means of a cam-
era :at the top of the windscreen. Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally.
If you have selected km as the display uni
tin
the Display unit Speed-/odome‐ ter (Y
page 239) function in the on-board
computer, Lane Keeping Assist assists you at
speeds above 60 km/h. If miles is selected
as the display unit, the assistance range
starts at 40 mph.
A warning may be given if a front wheel
passes ove ralane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1. 5seconds.

Standard
If Standard is selected, no warning vibration
occurs if:
R you have switched on the turn signals. In
this case, the warnings are suppressed for
a certain period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
Adaptive
If Adaptive is selected, no warning vibration
occurs if:
R you have switched on the turn signals. In
this case, the warnings are suppressed for
a certain period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognises certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a motor-
way.
R the system recognises solid lane markings. Driving systems

Lane-correcting brake application G
WARNING
Active Lane Keeping Assist does not keep
yourv ehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Corrective braking may
not always be sufficien tto return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen- tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correc
tsteering and for braking in good time.
Always adap tyour driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. If a lane-correcting brake application occurs,
the display shown in the illustration appears
in the multifunction display.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Before this, a warning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. 216
