Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. Aparking symbol indicates asuit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting aparking space. Park-
ing Assist PARKTRONIC is also available
(
Ypage 161).
Important safety notes
Parking Pilot is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting aparking
space. Make sure that no persons, animals or
object sare in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
GWARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result in acollision with another road user.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot
parking procedure.
!If unavoidable,y ou should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
RSnowfall or heavy rain may lead to aparking
space being measured inaccurately.
RPay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (
Ypage 162).
RYou can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled.
RWhen transporting aload that protrudes from
your vehicle, you must not use Parking Pilot.
RNever use Parking Pilot when snow chains are
mounted.
RMake sure that the tire pressures are always
correct.T his hasadirect influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are:
Rthat are paralleloratr ight-angles to the direc-
tion of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on the
pavement
Detecting parking spaces
Object slocated above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, truck overhangs or
loading ramps. Parking Pilot may therefore
guide you into the parking space too early.
Parking Pilot does not assist you parking in
spaces perpendicular to the direction of travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to alow
obstacle such as alow curb
Ryou forward-park
Parking Pilot does not assist you parking in
spaces parallelorp erpendicular to the direction
of travel if:
Rthe parking space is on acurb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. atree, apost or atrailer

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics) ,you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize aMOExtended tire by the
MOExtended marking which appears on the
sidewal lofthe tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speedi ndex (
Ypage302).
MOExtended tires may be used only in conjunc-
tion with an activated tire pressure loss warning
