Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
can assist you during maneuvering and parking. Parking Assist PARKTRONIC is also available
(Y page 139).
Important safety notes Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Make sure that no persons, animals or
objects are in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot parking procedure.
! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita- ble for parking, e.g.:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces
Parking tips:
R On narrow roads, drive as close to the parking
space as possible.
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 a parking
space being measured inaccurately.
R Pay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (Y page 140).
R You can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled.
R When transporting a load that protrudes from
your vehicle, you must not use Parking Pilot.
R Never use Parking Pilot when snow chains are
mounted.
R Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are:
R parallel 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 Objects located 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. G
WARNING
If there are objects above the detection range:
R Parking Pilot may steer in too early
R the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
For further information on the detection range
(Y page 139).
Parking Pilot does not assist you parking in
spaces parallel to the direction of travel if:
R the parking space is on a curb
R the parking space is apparently blocked, for
example by foliage or grass paving blocks 142

Parking Pilot is activated automatically when
driving forwards. The system is operational at
speeds of up to approximately 22 mph
(35 km/h). While in operation, the system inde- pendently locates and measures parking spaces on both sides of the vehicle.
Parking Pilot will only detect parking spaces:
R parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than your
vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol 0044as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. Park- ing Pilot only displays parking spaces on the
front-passenger side as standard. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain activated until you confirm the
use of Parking Pilot by pressing the 0076button
on the multifunction steering wheel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 50 ft
(15 m) away from it.

Parking tips:
R The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Parking Pilot 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 curb. If necessary, you
should abort the parking procedure with Park- ing Pilot.
R You can also select preselect transmission
position D. The vehicle redirects and does not
drive as far into the parking space. Should the transmission change take place too early, the
parking procedure will be canceled. A sensi-
ble parking position can no longer be ach-
ieved from this position.
Exiting a parking space In order for Parking Pilot to support you when
exiting the parking space:
R
you need to have parked using Parking Pilot.
R the border of the parking space must be high
enough at the front and the rear. A curb stone
is too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvered into the parking
space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using Parking
Pilot. X

detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid to the driver. It
might not always recognize fatigue or increasing inattentiveness in time or fail to recognize them
at all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/ h)
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset when you continue
your journey and starts assessing your tiredness
again if:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break

On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you do
not take a break and ATTENTION ASSIST still
detects increasing lapses in concentration, you will be warned again after 15 minutes at the
earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
Vehicles with the COMAND multimedia sys-
tem: if a warning is output in the multifunction
display, a service station search is performed in the multimedia system. You can select a servicestation and navigation to this service station will
then begin. This function can be activated or
deactivated in the multimedia system; see the
Digital Operator's Manual. Blind Spot Assist
General notes Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you will
also receive an optical and audible warning.
Blind Spot Assist supports you from a speed of
approximately 20 mph (30 km/h).
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance. Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
