Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly
R parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R snowfall or heavy rain may lead to aparking
space being measured inaccurately
R pay attention to the PARKTRONIC
(Y page 199) warning messages during the

chains are fitted
R make sure that the tyre pressures are always
correct. This has adirect influenc eonthe
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Object
slocated 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 cal- culated, e.g. overhangin gloads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are object sabove the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in frontoft hese
objects
This could cause acollision. There is arisk of
an accident. If object
sare located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 198).
Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to alow
obstacle such as alow kerb
R you forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
R the parking space is on akerb
R the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. atree, apost or atrailer :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional 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. 202
