Important safety notes G
WARNING
PARKTRONIC and Active Parking Assist are
merely parking aids and may not detect all
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
immediate surroundings when parking,
exiting parking

spaces and maneuvering. You
could otherwise endanger yourself and
others. G
WARNING
When parking or exiting a parking space, 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 steering.
To stop the vehicle or to avoid an accident,
you need to apply the brakes yourself.
G
WARNING
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! 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 is an electronic parking
aid with ultrasound. Active steering
intervention can assist you when parking or 186
Driving systems
Driving and parking

exiting a parking space. You may also use
PARKTRONIC (
Y page 183). When
PARKTRONIC is switched off, Active Parking
Assist is also unavailable.
Parking tips:
R pay attention to the PARKTRONIC
(Y page
185) 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 never use Active Parking Assist when snow
chains or an emergency spare wheel are
mounted.
R make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Parking Detecting a parking space
G
WARNING
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. This may lead to
a collision. For this reason, you should avoid
using Active Parking Assist in such situations. G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommend parking spaces that
are not suitable for parking. For example,
these might be spaces where parking is
prohibited, driveways, unsuitable surfaces,
etc. Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when
the

vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could
cause an accident and injure yourself and
others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. Example: detected parking space
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. At a speed below 19 mph
(30 km/h), you will see parking symbol ; as
the status indicator in the instrument cluster.
If a parking space has been detected, an
arrow pointing to the right = or left : is also
displayed.
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. If you wish to park
in a space on the driver's side, the indicator
on the driver's side must remain on. The turn
signal must remain switched on until you
acknowledge the use of Active Parking Assist Driving systems
187Driving and parking Z

by pressing the
a button on the
multifunction steering wheel.
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 40 in (1.0 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.
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
Backing up into the parking space G
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
oncoming lane

during the parking procedure.

must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist

Parking tips:
R on narrow roads, drive past the parking
space as close 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 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. In some cases, Active Parking
Assist may guide 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 abort 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 G
