at least 39.5 in (1.0 m) longer than your vehi-
cle 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 Note that Active Parking Assist cannot
measure the size of a parking space if it is 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 the 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 park-
ing spaces on the front-passenger side. 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 switched on until you acknowl-
edge the use of Active Parking Assist by press-
ing the v button on the multifunction steer-
ing 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 driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.

G WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if: R
there is a malfunction in the system or in
the voltage supply. 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.
Before leaving the vehicle, always secure it
against rolling away. i When PARKTRONIC detects obstacles,
Active Parking Assist brakes automatically
during the parking process. You are respon-
sible for braking in good time. X

The Park Assist Active Select R Observe
Surroundings message appears in the multi-
function display.
As soon as the parking procedure is complete,
the Park Assist Switched Off message
appears and a warning tone sounds. The vehicle
is now parked.
The vehicle is kept stationary without the driver
having to depress the brake pedal. The braking
effect is canceled when you depress the accel-
erator pedal.
Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. When Active Parking Assist is finished,
you must steer and brake again yourself.
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 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 cancel the parking procedure with
Active Parking Assist. 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 that Active Parking Assist can support
you when you exit the parking space: 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, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvering into the parking
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 the vehicle parallel to the direction of travel using
Active Parking Assist.
i If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time. X
Start the engine. X
Release the electric parking brake. X
Switch on the turn signal in the direction you
are pulling away. X

ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
(200 km/h) range. If ATTENTION ASSIST
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 you are driving with the active Steer Assist
of DISTRONIC PLUS R
if the time has been set incorrectly R
in active driving situations, such as when you
change lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when continuing the
journey, 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
Displaying the attention level
You can have current status information dis-
played in the assistance menu ( Y
page 247) of
the on-board computer. X
Select the Assistance display for Attention
Assist using the on-board computer
( Y
page 246).
The following information is displayed: R
length of the journey since the last break. R
the attention level determined by ATTENTION
ASSIST ( Attention Level ), displayed in a
bar display in five levels from high to low. R
If ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System Suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer ( Y

severe impact or in the event of damage to the

checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring area In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain, snow or spray R
there are narrow vehicles, e.g. motorcycles or
bicycles R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles driving at the inner
edge of their lanes. Due to the nature of the system: R
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders. R
the warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.

Warning display
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. Red warning lamp C flashes. If the turn
signal remains on, vehicles detected are indica-
ted by the flashing of red warning lamp C .
There are no further warning tones.Driving systems 217
