effect is cancelled when you depress the accel-
erator pedal.
Parking Pilot no longer supports you with steer- 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 of and
behind it and the conditions of the location. It
is possible that Parking Pilot could guide you
too far or not far enough into a parking space. In some cases, it may also lead you across or 198
Driving systemsDriving an
d parking

onto the kerb. If necessary, you should cancel
the parking procedure with Parking Pilot.
R You can also preselect transmission position
h. The vehicle redirects and does not drive
as far into the parking space. Should the
transmission change take place too early, the
parking procedure is cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order that Parking Pilot can support you when
exiting the parking space:
R you need to have parked using Parking Pilot
R the border of the parking space must be high
enough at the front and the rear. A kerb stone 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 manoeuvred into the parking
space
R a manoeuvring distance of at least 1.0 mmust
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 Vehicles with automatic transmission:
If Parking Assist PARKTRONIC detects obsta-
cles, Parking Pilot brakes automatically whilst the vehicle is exiting 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
will drive out of the parking space.

Information in the Digital Owner's Man-
ual In the Digital Owner's Manual, you will find infor-
mation on the following topics:
R Displays in the COMAND display
R Images displayed with PARKTRONIC display
Stopping the 360° camera display As soon as your vehicle exceeds a speed of

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed 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. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect 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 in the following situations:
R 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 contains potholes
R in the event of strong crosswinds
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 at a speed
below 60 km/h or above 200 km/h R
if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your tiredness again when you continue your
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 226) of
the on-board computer.
X Select the assistance graphics display for
ATTENTION ASSIST using the on-board com-
puter (Y page 226).
The following information is displayed:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST( Attention level 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 output a warn-
ing, the System suspended System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h.

board computer (Y page 227).

Important safety notes
G
WARNING
If you operate information and communica-
tion equipment integrated in the vehicle when driving, you could be distracted from the traf-
fic situation. This could also cause you to lose control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the traffic
situation permits. If you cannot be sure of this,
stop the vehicle paying attention to road and
traffic conditions and operate the equipment
with the vehicle stationary.
You must observe the legal requirements for the
country in which you are currently driving when operating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer shows only display mes- sages or warnings from certain systems on the
multifunction display. You should therefore
make sure your vehicle is operating safely at alltimes.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos-
sible. Contact a qualified specialist workshop.
For an overview, see the instrument cluster illus-
tration (Y page 34). Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster auto-
matically controls the brightness of the multi-
function display. In daylight, the displays in the
instrument cluster are not illuminated. The lighting in the instrument cluster, in the dis-
plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 34).
X Turn the brightness control knob clockwise or
anti-clockwise.
If the light switch is set to the Ã,Tor
L position, the brightness is dependent
upon the brightness of the ambient light. Speedometer with segments
The speedometer is divided into segments on
vehicles with Distance Pilot DISTRONIC.
The segments in the speedometer indicate
which speed range is available.
R Variable speed limiter is activated
(Y page 178):
The segments light up from the start of the
scale to the selected speed limitation.
R Distance Pilot DISTRONIC is activated
(Y page 180):
One or two segments in the stored speed
range light up.
R Distance Pilot DISTRONIC detects a vehicle in
front moving more slowly than the stored
speed:
The segments between the speed of the vehi- cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The engine is limited within a range to protect
the engine when the red band is reached. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature. Displays and operation
