Example: sensors in the front bumper,
left-hand side
Range of the sensors The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 196). Side view Top view
Front sensors
Centre Approximately 100 cm
Corners Approximately 80 cm
Rear sensors
Centre Approximately 120 cm
Corners Approximately 80 cm
!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. Parktronic
does not detect such objects when they are
in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects. Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brake
system or a pneumatic drill could cause
Parktronic to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 20 cm
If there is an obstacle within this range, all
warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
The warning display for the rear area is loca-
ted on the roof lining in the rear compart-
ment.Controls

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, i.e.
not on the pavement, for example;
Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces which are littered, over-
grown or partially occupied by trailer tow-
bars might not be identified properly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the Parktronic warning
messages during the parking procedure
(Y page 120).
R You can intervene in the steering procedure
to correct it at any time. Active parking
assist will then be cancelled.
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
fitted. R
Make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
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 as well as the condition
of the location. In some cases, Active park-
ing assist may guide you too far into a park-
ing space, or not far enough into it. In some
cases it may also lead you across or onto
the kerb. If necessary, you should abort the
parking procedure with Active parking
assist.
R You can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be aborted.
! When unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise you may damage
the wheel rims or tyres. Detecting parking spaces Active parking assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 35 km/h, you will see
the parking symbol as a status indicator in the
instrument cluster. Active parking assist only
displays parking spaces on the front-
passenger side as standard. Parking spaces
on the driver's side are displayed as soon as
the turn signal on the driver's side is activa-
ted. If you wish to park in a space on the driv-
er's side, the indicator on the driver's side
must remain on. This must remain switched
on until you acknowledge the use of Active
parking assist by pressing the jbutton on
the multi-function steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. Controls
