Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically so that the set speed is not exceeded.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. By doing
so, you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the distance to the vehicle in front or take evasive action provided it is safe to
do so.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Distance Pilot DISTRONIC ope rates in the range
b etween 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DISTRONIC while driv-
ing on roads with steep gradients.
Since Distance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Tips for driving with Distance Pilot
DISTRONIC General notes Pay particular attention in the following traffic
situations: R
Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles during cornering is limited. Your vehi-
cle may brake unexpectedly or late. R
Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles which are
not driving in the middle of their lane. The dis-
tance to the vehicle in front will be too short. R
Other vehicles changing lanes: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short. R
Narrow vehicles: Distance Pilot DISTRONIC
has not yet detected the vehicle in front on
the edge of the road because of its narrow
width. The distance to the vehicle in front will
be too short. R
Obstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-
cle or stationary vehicle is then revealed, Dis-
tance Pilot DISTRONIC will not brake for
them. R
Crossing traffic: Distance Pilot DISTRONIC
may mistakenly detect vehicles that are
crossing your lane. Activating Distance Pil ot
DIST
RONIC at, for example, a traffic light with
crossing traffic, could cause your vehicle to
pull away at the wrong time.
In such situations, brake if necessary. Distance
Pilot DISTRONIC will then be deactivated. Distance Pilot DISTRONIC with Steering
Pilot General notes
Distance Pilot DISTRONIC with Steering Pilot
aids you in keeping the vehicle in the center of
the driving lane by means of moderate steering
interventions in a speed range from 0 - 125 mph
(0 - 200 km/h).
It monitors the area in front of your vehicle by
means of camera system C at the top of the
windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
the extended automatic Re-start in traffic jams
focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Pilot focuses on clear lane markings
(left and right), only focusing on the vehicle in
front if clear lane markings are not present.
If these conditions are not present, Steering
Pilot cannot provide assistance.
Distance Pilot DISTRONIC must be active in
order for the function to be available.
Important safety notes
If you fail to adapt your driving style, Distance
Pilot DISTRONIC and Steering Pilot can neither
reduce the risk of an accident nor override the
laws of physics. It cannot take into account
road, weather or traffic conditions. Distance
Pilot DISTRONIC with Steering Pilot is only an
a i d. You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking in
good time and for staying in your lane.
Distance Pilot DISTRONIC with Steering Pilot
does not detect road and traffic conditions and
does not detect all road users. If you are follow-
ing a vehicle which is driving towards the edge of
the road, your vehicle could come into contactDriving system s 177
Dr ivi ng an d parking Z

with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
Distance Pilot DISTRONIC with Steering Pilot
cannot continuously keep your vehicle in lane. In
some cases, the steering intervention is not suf-
ficient to bring the vehicle back to the lane. In
such cases, you must steer the vehicle yourself
to ensure that it does not leave the lane.
The support provided by the system can be
impaired if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or heavy spray R
there is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no or several unclear lane markings
for one lane, e.g. roadworks R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross on e another or mergeR
the road is narrow and winding R
there are strong shadows cast on the road
The system is switched to passive and no longer
assists you by performing steering interventions
if: R
you actively change lane R
you switch on the turn signal R
take your hands off the steering wheel or do
not steer for a prolonged period of time
i After you have finished changing lanes,
Steering Pilot is automatically active once
more. Steering Pilot cannot provide assistance: R
on very sharp corners R
when towing a trailer R
when a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Distance
Pilot DISTRONIC ( Y
page 171).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Pilot is
then switched to passive. Distance Pilot
DISTRONIC remains active.

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
and brake application can assist you during
parking. Parking Assist PARKTRONIC is also
available ( Y
page 187).
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 path of your vehicle.
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 they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may show parking spaces which
are not suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces190
Driving systems
Driving and parking

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 Assist PARKTRONIC during the park-
ing procedure ( Y
page 187).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 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 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/exiting procedure is
calculated, e.g. overhanging loads, tail sections
or loading ramps of trucks. Parking Pilot may
therefore guide you into the parking space too
early.
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. Further information about the detection range
( Y
page 188).
Parking Pilot does not assist you parking in
spaces at a right angle 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 a low
obstacle such as a low curb R
you park forwards
Parking Pilot does not assist you parking in
spaces parallel with or at a right angle to the
direction of travel if: R
the parking space is on a curb 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 maneu-
ver into R
the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
C
Detected parking space on the left D

i Note that Parking Pilot PARKTRONIC cannot
measure the depth of parking spaces if they
are at right angles to the direction of travel.
You will need to judge whether your vehicle
will fit into the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol D as 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 v button
on the multifunction steering wheel. The system
automatically determines whether the parking
space is parallel or at right angles to the direc-
tion of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.

ing interventions and brake applications. When
Parking Pilot is finished, you must steer and
brake again yourself. Parking Assist
PARKTRONIC is still available.
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. Cancel the parking
procedure with Parking Pilot if necessary. 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 assist you: R
the border of the parking space must be high
enough at the front and the rear. A curb is too
small, for example. R
the border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in 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 the Park-
ing Pilot.
i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically
whilst the vehicle is exiting the parking space.
