TheParkAssistActiveSelect RObserveSurroundingsmessage 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:
RThe 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.
RYou 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:
Rthe border of the parking space must be high enough at the front and the rear. A curb is too
small, for example.
Rthe 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.
Ra 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.
iIf PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time.
XStart the engine.
XRelease the electric parking brake.
XSwitch on the turn signal in the direction you
are pulling away.
XShift the transmission to position Dor R.

XPull away, being ready to brake at all times. Do
not exceed a maximum speed of approx-
imately 6 mph (10 km/h) when exiting a park-
ing space. Otherwise Active Parking Assist
will be canceled.
XDepending on the message or as required,
shift the transmission to position Dor R.
Active Parking Assist immediately steers in
the other direction. The Park Assist
Active Accelerate and BrakeObserveSurroundingsmessage appears in the mul-
tifunction display.
iYou will achieve the best results by waiting
for the steering procedure to complete before
pulling away.
If you back up after activation, the steering
wheel is moved to the straight-ahead posi-
tion.
XDrive forwards and back up as prompted by
the PARKTRONIC warning displays, several
times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and the
Park

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:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
Rif you are driving with the active Steer Assist
of DISTRONIC PLUS
Rif the time has been set incorrectly
Rin active driving situations, such as when youchange lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when continuing the
journey, if:
Ryou switch off the engine
Ryou 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 (Ypage 247) of
the on-board computer.
XSelect the Assistance display for Attention
Assist using the on-board computer
(
Ypage 246).
The following information is displayed:
Rlength of the journey since the last break.
Rthe attention level determined by ATTENTION ASSIST ( Attention Level), displayed in a
bar display in five levels from high to low.
RIf 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
XActivate ATTENTION ASSIST using the on-
board computer (Ypage 248).
The system determines the attention level of
the driver depending on the setting selected:
214Driving systems
Driving and parking

SelectionStandard: the sensitivity with which
the system determines the attention level is set
to normal.
Selection Sensitive
: the sensitivity is set
higher. The attention level detected by Attention
Assist is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated (stand-
ard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display: ATTENTION ASSIST
Take aBreak!.
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
XIf necessary, take a break.
XConfirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you do
not take a break and ATTENTION ASSIST still
detects increasing lapses in concentration, you
will be warned again after 15 minutes at the
earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated
in COMAND.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit. Traffic Sign Assist is a map-based system, and
for this reason, traffic signs put up temporarily
(e.g. near roadworks) are not detected.
If a traffic sign that is relevant to your vehicle is
passed, the display of the speed limits is upda-
ted.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown.
The traffic signs are only displayed with the
restrictions if:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail-
able sources, no speed limit is displayed in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (
Ypage 246).
Important safety notes
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.

Switching on Blind Spot Assist
XMake sure that Blind Spot Assist
(Ypage 248) is activated in the on-board
computer.
XTurn the SmartKey to position 2in the ignition
lock.
Warning lamps :in the exterior mirrors light
up red until the engine is started.
Display in the assistance graphic
When Blind Spot Assist is activated, gray radar
waves propagating backwards appear next to
the vehicle in the assistance display in the mul-
tifunction display. Above a speed of 20 mph
(30 km/h), the color of the radar waves in the
assistance display changes to green :. Blind
Spot Assist is then ready for use.
Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :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. 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 steering wheel for
up to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot 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.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
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 Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep- ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
218Driving systems
Driving and parking

drive system automatically selects the most effi-
cient operating mode for every driving situation.Drive the vehicle in the usual manner.
To save fuel in HYBRIDmode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. When power output require-
ments are high, the combustion engine is auto-
matically switched on. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine
using the power stored in the high-voltage bat-
tery. In addition, the power is used for partially
electric driving, operation of the electric coolant compressor and to support the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on plug-in hybrid oper-
ation (
Ypage 230).
Recuperative Brake System
If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (
Ypage 45).
Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
Ra message appears in the multifunction dis-
play and
Ra warning tone sounds
Further information (
Ypage 272).
All of the vehicle's systems remain active, if:
Rthe vehicle is stationary
Rthe combustion engine is switched off and
Rthe READY indicator in the instrument cluster
lights up If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
may pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function (
Ypage 231).
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This is the case, for example, when
you are parking and your vehicle is not seen by
other road users.
This requires you to adopt a particularly antici-
patory driving style, as it is necessary to allow
for the possibility that other road users may
behave erratically.
