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
( Y
page 224).
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. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G WARNING
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 Park-
ing 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.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces Driving systems 227
Driving and parking Z

Parking tips: R
On narrow roads, drive as close to the park-
ing space as possible. R
Parking spaces that are littered or over-
grown might be identified or measured
incorrectly. R
Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly. R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately. R
Pay attention to the PARKTRONIC
( Y
page 225) 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 canceled. R
When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist. R
Never use Active Parking Assist when snow
chains are installed. R
Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
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
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.
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.
For further information on the detection
range ( Y
page 224).
Active Parking Assist does not support you
parking in spaces that are parallel to the
direction of travel if: R
the parking space is on a curb R
the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks R
the area is too small for the vehicle to
maneuver into R
the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer
C

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 driv-
er'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 the v
button on the multifunction steering wheel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) awa y from it .

Parking tips: 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 Driving system s 229
Dr ivi ng an d parking Z

some cases, it may also lead you across or
onto the curb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist. R
You can also select preselect transmission
position D . 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 sup-
port you when you exit the parking space: R
you need to have parked using Active Park-
ing Assist. R
the border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example. R
the 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 park-
ing space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available. X
Start the engine. X
Release the electric parking brake. X

appears in the multifunction display. You will
then have to steer and merge into traffic on
your own. PARKTRONIC is still available. You
can take over the steering, before the vehicle
has exited the parking space completely. This
is useful, for example when you recognize
that it is already possible to pull out of the
parking space.230

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( Y
page 244) and Lane Keeping
Assist ( Y
page 246).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. 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 col-
lision warning.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/ h) . Important safety notes
G WARNING
Blin d Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which appr oach with a large speed
differential and overtake your vehicle
As a result, Blin d Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
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.
