Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
parking.
You may also use PARKTRONIC
(Ypage 222).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active
Parking Assist parking procedure.
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
226Driving systems
Driving and parking

Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 224) warning messages during the
parking procedure.
RAt any time, you can intervene in the
steering procedure to correct it. Active
Parking Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthat are parallel to the direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g.
not on the pavement
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.
GWARNING
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.
For further information on the detection
range (Ypage 223).
Active Parking Assist does not support you
with parking spaces parallel to the direction
of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
Rthe area is too small for the vehicle to
maneuver into
Rthe parking space is bordered by an
obstacle, e.g. a tree, a post or a trailer
CDetected parking space on the left
DParking symbol

Active Parking Assist will only detect parking
spaces:
Rthat are parallel to the direction of travel
Rthat are at least 59 in (1.5 m) wide
Rthat are at least 51 in (1.3 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. 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. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing thev
button on the multifunction steering wheel.
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

Active Parking Assist merely aids you by
intervening actively in the steering. If you do
not brake there is a risk of an accident.
Always apply the brakes yourself when
maneuvering and parking.

Parking Assist is finished, you must steer
again yourself. PARKTRONIC is still available.
Parking tips:
RThe 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.
RYou can also select preselect transmission
positionD. The vehicle redirects and does
not drive as far into the parking space.
Should the gear change occur too soon to
achieve a sensible parking position, the
parking procedure will be aborted.
Exiting a parking space
In order that Active Parking Assist can
support you when you exit the parking space:
Ryou need to have parked using Active
Parking Assist.
Rthe border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvered into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available.

Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
Rthere are no, several or unclear lane
markings for a lane, e.g. in areas with road
construction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the lane
Switching on Lane Keeping Assist
XSwitch on Active Lane Keeping Assist using
the on-board computer; to do so, select
StandardStandardorAdaptiveAdaptive(Ypage 282).
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected,
the lines in the assistance graphics display
(Ypage 280) are shown in green. Lane
Keeping Assist is ready for use.

IfStandardStandardis selected, no warning vibration
occurs if:
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
