Active Parking Assist no longer supports you
with steering interventions and brake appli-
cations. When Active Parking Assist is fin-
ished, you must steer and brake again your-
self. PARKTRONIC is still available. Parking tips:
RThe 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.
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 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:
Ryou need to have parked using Active Park-
ing Assist.
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 park- ing 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.

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.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (
Ypage 213) and Lane Keeping
Assist (
Ypage 215).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
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 warn-
ing.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/h). Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles 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.
iUSA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to

Radar sensors
The radar sensors for Blind Spot Assist are
integrated into the rear bumper. Make sure
that the bumpers are free from dirt, ice or
slush. The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified spe-
cialist workshop. Blind Spot Assist may no
longer work properly.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 25).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems 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 only shows messages
or warnings from certain systems in the mul-
tifunction display. You should therefore make sure your vehicle is operating safely at all
times.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do
so. Contact a qualified specialist workshop.
For an overview, see the instrument panel
illustration (
Ypage 31).
Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays
in the instrument cluster are not illuminated.
The lighting in the instrument cluster, in the
displays and the controls in the vehicle inte-
rior can be adjusted using the brightness con-
trol knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(
Ypage 31).
XTurn the brightness control knob clockwise
or counter-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
only on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available.
RDISTRONIC PLUS activated (Ypage 186):
One or two segments in the set speed
range light up.
RDISTRONIC PLUS detects a vehicle in front
that is driving at a slower speed than the
stored speed:
The segments between the speed of the
vehicle in front and the stored speed light
up.
218Displays and operation
On-board computer and displays
Tachometer
!
Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer 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 con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul-
tifunction display (
Ypage 221).
There is a short delay before a change in out-
side temperature appears in the multifunc-
tion display.
Coolant temperature display
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side
(
Ypage 31). Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †).
