TheParkAssistActiveSelect RObserveSurroundingsmessage appears in the multi-
function display.
As soon as the parking procedure is complete,
the Park Assist Switched Off
message
appears and awarning ton esounds. The vehicle
is now parked.
The vehicle is kept stationary without the driver having to depress the brake pedal. The braking
effect is canceled when you depress the accel-
erator pedal.
Active Parking Assist no longer supports you
with steerin ginterventions and brake applica-
tions. When Active Parking Assist is finished,
you must steer and brake again yourself.
PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous 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 aparking space, or not
far enough into it. In some cases, it may also
lead you across or ontot he curb. If necessary,
you should cancel the parking procedure with
Active Parking Assist.
RYou can also select preselect transmission
position D.The vehicle redirectsa nd does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. Asensi-
ble parking position can no longer be ach-
ieved from this position.
Exiting aparking space
In order that Active Parking Assist can support
you when you exit the parking space:
Rthe border of the parking space must be high
enough at the front and the rear. Acurb 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 maneuvering into the parking
space.
Ram aneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exitin gaparking space if you have parked the vehicle parallel to the direction of travel using
Active Parking Assist.
iIf PARKTRONIC detect
sobstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time.
XStart the engine.
XRelease the electric parking brake.
XSwitch on the turn signal in the direction you
are pulling away.
