the camera, e.g. on the vehicle front end
or the running gear.
P
lease also observe text messages that
appear in the display of the instrument
cluster and the Infotainment system.
No sensor or camera view, or the park-
ing system has been switched o
The sensor area is switched o permanent-
ly if a sensor fails. The aected sensor area
can be displayed by the
symbol and a grey
ima
ge segment
in the Infotainment sys-
tem. T
he parking system is switched o
completely if necessary.
If there is a fault in the parking sensors, an
acoustic signal will sound for several sec-
onds when it is switched on. A text notifica-
tion may also be shown on the instrument
cluster display.
1. Check whether one of the listed causes
is present.
2. Switch the system on again once you
have rectified the source of the fault.
3. If the problem persists, go to a corre-
spondingly qualified workshop.
Active Park Assist is active and the ve-
hicle brakes
In some countries, Active Park Assist can
assist the driver with an automatic braking
intervention in certain situations
→ page 191.
Depending on the vehicle equipment and
certain conditions, e.g. weather, load or in-
clination of the vehicle, Active Park Assist
can automatically brake the vehicle before
an obstacle. Following this intervention, the
driver must depress the brake pedal.
The parking manoeuvre is ended if an auto-
matic braking intervention occurs.
Active Park Assist is active and the
parking manoeuvre is automatically
cancelled
Active Park Assist automatically cancels
a parking procedure if one of the following
criteria is met:
— The
function button is pressed.
—
The driver intervenes using the steering
wheel.
— The driver door is opened.
— The time limit or number of manoeuvres
for parking are exc
eeded.
— TCS is switched o or is taking corrective
action.
— There is a fault in the system.
Start the parking procedure again
→ page 198.
Active Park Assist is active and sup-
ports steering movements when the ve-
hicle is stationary
If Active Park Assist attempts to turn the
steering wheel when the vehicle is station-
ary, the white symbol
appears on the in-
strument cluster displa
y.
1. Depress the brake pedal.
Active Park Assist parks inaccurately
aer a wheel change
If Active Park Assist parks inaccurately aer
a wheel change (e.g. vehicle is too far away
or too close to the kerb), it may be neces-
sary for the system to adopt the new wheel
circumferences.
1. Drive a longer distance with the vehicle,
including curves.
Active Park Assist learns the new wheel cir-
cumferences automatically.

Introduction
The parking sensors assist the driver
when manoeuvring and parking.
