sides 3 can also be displayed in the head-up dis-
play.
System limits
Parking Assist PARKTRONIC does not necessarily
take into account the following obstacles:
= Obstacles below the detection range, e.g. per-
sons, animals or objects.
= Obstacles above the detection range, e.g.
overhanging loads, overhangs or loading
ramps of truck.
= Pedestrians or animals approaching the vehi-
cle from the side.
= Objects placed next to the vehicle
Obstacles on the sides are not shown in the fol-
lowing situations, for example:
= You park the vehicle and switch it oM.
= You open the doors.
Aser the engine is restarted, obstacles must be
detected again by driving past them before a new
warning can be issued.
Also observe the system limits of the following
systems:
= Rear view camera (  page 220)
= 360° camera (  page 223)
Observe the information on vehicle sensors and
cameras; the system otherwise cannot function properly (  page 179).230Driving and parking

Active Parking Assist

qFunction of Active Parking Assist
Active Parking Assist is an electronic parking
assistance system that uses ultrasound with the assistance of the rear view camera and 360°
Camera. When you are driving forwards up to
approximately 22 mph (35 km/h), the system automatically measures parking spaces on both
sides of the vehicle.
Active Parking Assist oMers the following func-
tions:
Vehicles with rear view camera
= Parking in parking spaces parallel to the road
= Backing up into parking spaces perpendicular
to the road
Vehicles with 360° Camera
= Parking in parking spaces parallel to the road
= Parking in parking spaces perpendicular to the
road (optionally either forwards or reverse)
= Parking in parking spaces that can only be
detected as such due to markings (forexample
at the roadside)
= Exiting a parking space parallel to the road
= Exiting a parking space perpendicular to the
road (optionally either les or right)
Active Parking Assist is only an aid. It is not a sub-
stitute for your attention to the surroundings. The responsibility for safe maneuvering and parking
remains with you. Make sure that no persons, ani- mals or objects etc. are in the maneuveringrange.
If Active Parking Assist is available, the Ç mes-
sage appears in the driver\bs display. When thesystem detects parking spaces, È appears.
The arrows show on which side of the road free
parking spaces are located. These are then shown
in the central display.
When Active Parking Assist is activated, the turn signal indicators are activated based on the calcu-
lated path of your vehicle. When you are entering
or exiting a parking space, the procedure is assis-
ted by acceleration, braking, steering and gear changes.
To start the parking procedure, press the E
button (  page 234).
Active Parking Assist will be canceled in the fol- lowing situations:
= You deactivate Parking Assist PARKTRONIC.
= You press the E button again.
= You begin steering.
= You engage transmission position ].
= ESP n
intervenes.
= You open the driver\bs door.232Driving and parking

System limits
Also observe the system limits of the following
systems:
= Rear view camera (  page 220)
= 360° Camera (  page 223)
Objects that are above or below the detection
range of Active Parking Assist, e.g. protruding
loads, overhangs or loading ramps of trucks or boundaries of parking spaces, are not detected
when measuring the parking space. These are
also then not taken into account when calculating the parking procedure. In some circumstances,
Active Parking Assist may therefore guide you into the parking space prematurely or brake too late.
Certain environmental conditions, suchas snowfall or heavy rain, may lead to a parking space being
measured inaccurately. Parking spaces that are
partially occupied by trailer drawbars might not be
identiNed as such or be measured incorrectly.
Only use Active Parking Assist on level, high-grip
ground.&WARNING Risk of accident due to objects
located above or below the detection
range of Active Parking Assist
If there are objects above or below the detec-
tion range, the following situations may arise:
= Active Parking Assist may steer too early.
= The vehicle may not stop in front of these
objects.
There is a danger of collision!
In these situations, do not use Active Parking Assist.
Active Parking Assist can also display unsuitable
parking spaces, e.g. parking spaces in which
parking is not permitted or parking spaces on unsuitable surfaces.
Do not use Active Parking Assist in the following
situations:
= In extreme weather conditions suchas ice,
packed snow or in heavy rain.
= When transporting a load that protrudes
beyond the vehicle.
= If the parking space is on a steep downhill or
uphill gradient.
= When snow chains are installed.
= Directly aser a tire change or when spare tires
are installed.
= If the tire pressure is too low or too high.
= If the suspension is out of alignment, e.g. aser
bottoming out on a curb.
= On steep inclines of more than approximately
15 %.Driving and parking233

q Function of cross traPc warning
The cross traPc warning can warn you of crossing
traPc when you are exiting a parking space. The
radar sensors in the bumper also monitor the area
adjacent to the vehicle.
The cross traPc warning is active under the fol-
lowing conditions:
= Warning for Cross Traffic, Rear : the vehicle is
driving in reverse at a speed slower than approx. 6 mph (10 km/h).
= Warning for Cross Traffic, Front : the vehicle is
