ParkingDriving and parking

If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is
maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed. The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected the S or M driv-
ing program (Y page 150). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the E driving program, the vehicle
accelerates more gently. This setting is rec-
ommended in stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 43.5 mph
(70 km/h)
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
R you switch on the appropriate turn signal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles. Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating DIS-
TRONIC PLUS (Y page 173).
If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is
set using the control on the cruise control
lever. Driving systems
171Driving and parking Z

system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking spaces:
R that are parallel or at right-angles to the
direction of travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol 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. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv-
er'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
switched on until you acknowledge the use of Active Parking Assist by pressing the 0076
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right-angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it.

Parking tips: R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. It may be the case that Active
Parking Assist 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 can-
cel the parking procedure with Active Park- ing Assist.
R You can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should a gear be changed too early, the parking pro- cedure will be canceled. A sensible parking
position can no longer be achieved from
this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space:
R the border of the parking space must be
high enough. A curb is too small, for exam- ple.
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 maneuvering into the park-
ing space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with exiting a parking space if you have parked thevehicle parallel to the direction of travel using
Active Parking Assist.

General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 191) and Lane Keeping
Assist (Y page 193).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will also receive a visual and audible collision
warning. For this purpose, Blind Spot Assist
uses sensors in the rear bumper.
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.
i USA only: Driving systems

speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30 km/h), then warning lamp 0043on
the corresponding 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 differ-
ence in speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp 0043flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp 0043. There are no further warning tones.

ted in the on-board computer
(Y page 206).
X Turn the SmartKey to position 2in the igni-
tion lock.
Warning lamps 0043in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow. Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in
front of your vehicle with camera
0043, which is
mounted at 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.
This function is available in the range between
40 mph and 120 mph (60 km/h and
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 steer-
ing wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident. Driving systems
193Driving and parking
Z

You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep- ing Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics. Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane Keeping Assist is merely an aid. 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.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or 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
vicinity of the camera
R there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
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 strong shadows cast on the lane
Switching on Lane Keeping Assist
X Switch on Active Lane Keeping Assist using

green.
When Standard is selected, no warning vibra-
tion occurs if:
R you switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®

R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a free-
way.
R the system recognizes solid lane markings.
