Controls in detail
Warning display in the left-hand exterior
mirror for the area to the rear left-hand side
4 Left-hand side of vehicle
5 Indicator segments
The warning display is divided into 5 yellow
and 2 red segments for each side of the ve-
hicle. PARKTRONIC is operational if yellow
indicator segments 3 and 5 light up.
There is a malfunction if only the red seg-
ments of the warning display light up
(
e page 238).
The selector lever position determines
whether the front and/or rear area is mon-
itored.
One or more segments light up as the vehi-
cle approaches an obstacle, depending on
the vehicle's distance from the obstacle.
From the:
O sixth segment, an intermittent warning
tone sounds for approximately
2 seconds
O seventh segment, a continuous warn-
ing tone sounds. You have reached the
minimum distance.
Roll-back warning
PARKTRONIC automatically begins to mon-
itor the area behind the vehicle if the vehi-
cle begins to roll backwards without
reverse gear engaged, e.g. after stopping
on an uphill gradient.
If PARKTRONIC detects an obstacle no
more than 31 in (80 cm) away, all the seg-
ments of the warning displays light up. A
continuous warning tone sounds as the ve-
hicle approaches the obstacle and for a
further 2 seconds after the vehicle has
come to a halt.
Switching PARKTRONIC on/off
You can switch PARKTRONIC on and off
manually.
E Press upper part 1 of the f
switch.
If PARKTRONIC is switched off, the in-
dicator lamp in the switch lights up.
Trailer towing
If your vehicle has the corresponding elec-
trical basic wiring for towing and you hitch
up a trailer, PARKTRONIC is deactivated
for the rear area as soon as the electrical
connection is made between your vehicle
and the trailer.
Remove a detachable trailer coupling when
it is no longer required. PARKTRONIC mea-
sures the minimum detection range to an
obstacle from the bumper, not from the
ball coupling.
