Pilo tGeneral notes
Distanc e Pilo t DISTRONIC wit h Steerin g Pilo t
aids you in keepin g th e vehicle in th e middle of
th e lan e by means of moderat e steerin g inter-
vention s in a speed range from 0 – 12 5 mph
(0 - 20 0 km/h).
It monitors th e are a in fron t of your vehicle by
means of multifunction camera C , fixed at th e
to p of th e windshield .
In a speed range from 0 - 37 mph (0 - 60 km/ h) ,
Steering Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Pilot focuses on clear lane markings
(left and right), focusing on the vehicle in front
only 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
Distance Pilot DISTRONIC and Steering Pilot can
neither reduce the risk of an accident if you fail
to adapt your driving style nor override the laws
of physics. Distance Pilot DISTRONIC with
Steering Pilot cannot take into account road,
weather or traffic conditions. Distance Pilot
DISTRONIC with Steering Pilot is only an aid.
You are responsible for maintaining a safe dis-
tance to the ve hi
cle in front, for vehicle speed,
for braking in good time and for staying in 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 contact 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 markers on a con-
struction site that are 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.
DISTRONIC PLUS with Steering Pilot cannot
continuously keep your vehicle in lane. In some
cases, steering intervention is not sufficient 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 system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road su rface i s 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 one another or merge R
the road is narrow and winding R
there are highly variable shade conditions on
the roadway
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
you take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering
Pilot is automatically active once more.Driving systems 177
Driving and parking Z

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and: R
a system malfunction occurs R
the power supply is insufficient
If a malfunction occurs, the transmission may
also be shifted to position ] automatically.
DSR
General notes DSR (Downhill Speed Regulation) is an aid to
assist you when driving downhill that is available
only in vehicles with the Off-Road Engineering
package.
It keeps the speed of travel at the speed selec-
ted on the on-board computer. The steeper the
downhill gradient, the greater the DSR braking
effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position [ , ^
or \\ . You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes
G WARNING
If the speed driven and the set speed deviate
and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
DSR can neither reduce the risk of accident if
you fail to adapt your driving style nor override
the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for maintaining a
safe distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not always be able to keep to the set speed, depend-
ing on road surface and tire conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Further information about "Driving off-road"
( Y
page 165).
Activating/deactivating DSR If you activate DSR and no speed has been set,
the vehicle decelerates to 4 mph (6 km/h).
You can activate DSR only when driving at
speeds below 25 mph (40 km/h).

Driving and parking

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 and when exiting a parking space. You
can also still use Parking Assist PARKTRONIC
( Y
page 191).
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.
For vehicles with a trailer tow hitch installed, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa-
ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
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 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 Assist PARKTRONIC during the park-
ing procedure ( Y
page 193).R
You can intervene in the steering procedure
to correct it at any time. Parking Pilot is then
canceled- R
When transporting a load that protrudes from
your vehicle, you should not use Parking Pilot- R
Never use Parking Pilot when snow chains are
mounted. R
Always pay attention to the specified tire
pressure for your vehicle. 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 procedure is calcula-
ted, e.g. overhanging loads, tail sections or load-
ing 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.188

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.

Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Blind Spot Assist
is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. The red warning lamp flashes on the
relevant exterior mirror. If the turn signal
remains on, detected vehicles are indicated by
the flashing of the red warning lamp on the exte-
rior mirror. There are no further warning tones.

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era C which is attached behind the top of the
windshield. Active Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally.Driving systems 207
Driving and parking Z

This function is available in the range between
40 mph and 120 mph (60 km/ ha nd 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.

Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning lamp lights up in the exterior mirrors and draws your
attention to vehicles detected in the monitored
area. If you then switch on the corresponding
turn signal to change lane, you will also receive
an optical and audible warning. If a risk of lateral
collision is detected, corrective braking may
help you avoid a collision. Before a course-cor-
recting brake application, Active Blind Spot
Assist evaluates the space in the direction of
travel and at the sides of the vehicle. For this,
Active Blind Spot Assist uses the forward-facing
radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/ h) .
Important safety notes Active Blin d Spot Assist is only an aid and is not
a substitute for attentive driving.
G WARNING
Active 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 appr oach with a large speed
differential and overtake your vehicle
As a result, Active Blin d Spot Assist may ne i-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
