stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically applying the brakes.
Storing the current speed or calling up the
last stored speed G
WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.

Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting a parking space. When maneuvering,
parking or pulling out of a parking space, make
sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a truck or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you: R switch on the ignition
R shift the transmission to position D,Ror N
R shift the transmission to position D,Ror N
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h) . It is reactiva-
ted at lower speeds.
Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. people, ani-
mals or objects.
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. 0043
Sensors in the front bumper, left-hand side

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

0087 Detected parking space on the right
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.

WARNING
Parking Pilot merely aids you by intervening
actively in the steering. If you do not apply the brakes yourself, there is the risk of an acci-
dent. Always apply the brakes yourself while
maneuvering and parking.

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
