While the adjustment is taking place, a mes-
sage appears in the multi-function display,
e.g. : If you press the
æorç button on the
multi-function steering wheel, the messages
will disappear.
Once highway level has been reached, all indi-
cator lamps 3go out. You will see a message
in the multi-function display, for example: If you have not previously selected the off-
road menu (Y page 126) in the on-board
computer, the message disappears after
about five seconds.
The vehicle automatically selects highway
level if you are driving at a speed above 115 km/h or if you drive at between
100 km/h and 115 km/h for around 20 sec-
onds. At high speeds, the vehicle is lowered
to high-speed level in accordance with the
ADS basic setting (Y
page 157). Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distance
between your vehicle and an object. Parktronic is activated automatically when
you:
R
switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. 1
Example: sensors in the front bumper,

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 251). Side view Top view
Front sensors
Centre Approximately 100 cm
Corners Approximately 60 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 brakes
or a pneumatic drill could cause Parktronic
to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 15 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 in the
roof trim at the rear. Controls
