PARKTRONIC
Important safety notes G
WARNING
PARKTRONIC is only an aid and may not
detect all obstacles. It is not asubstitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visuallya nd
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitorst he area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
!
When parking, pay particular attention to
objectsa bove or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objectsw hen
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objectsw hich absorb ultrasonic sources. Ultrasonic sources, such as an automatic
car wash,
alorry's compressed-air brakes
or ap neumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. :
Example: sensors in the front bumper,
left-han dside
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function cor-
rectly. Cleant he sensors regularly,t aking
care not to scratchord amage them

Important safety notes G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommendp arking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could cause an accident and injure yourself and oth-
ers.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
WARNING
Objectsl ocated above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. Driving systems

Activ eParking Assist is an electroni cparking
aid wit hultrasound. Ultrasound is used to
measure th eroad on bot hsides of th evehicle.
As uitable parking spac eisindicated by the

can assis tyou during parking. You may also
use PARKTRONIC (Y page 185). When PARK-
TRONIC is switched off, Active Parking Assist
is also unavailable.
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, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to aparking
space being measured inaccurately. R
pay attention to the PARKTRONIC
(Y page 186) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correc tit. Active Parking
Assist will then be cancelled.
R when transporting aload which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergenc yspare
wheel are fitted, you should not use Active
Parking Assist here either.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the wa yyourv ehicl eisp ositioned 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 and the conditionsoft he
location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
ag ear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be cancelled. 188
