If the vehicle in front of you is stationary, you
can only activate DISTRONIC PLUS once your
vehicle is stationary as well.
i DISTRONIC PLUS can only be activated at
under 30 km/h if avehicle in front has been
detected. Therefore, the DISTRONIC PLUS
distance displayint he instrument cluster
should be activated (Y page 219).
i You can use the cruise control lever to set
the stored speed and the control on the
cruise control lever to set the specified
minimum distance (Y page 176).
Pulling away and driving G
WARNING
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. In such cases, control the distance
from vehicles travelling in front with the brake
alone. You could otherwise cause an accident
and thereby injure yourselfa nd others. The
driver remains fully responsibl efor the vehi-
cle's distance from othe rvehicles, the speed
being driven and for braking in good time. X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ;,orp ress it up :or down =.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
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 fron thas slowe ddown ,itb rakes yourv ehi-
cle. In this way, the distanc eyou have selec-
ted is maintained.
If DISTRONIC PLUS detects that the vehicle
in fron tisdriving faster, it accelerates your
vehicle, but only up to the speed you have
stored.
Changing lanes G
WARNING
DISTRONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
They do not relieve you of the responsibility
of paying attention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
If you change to the overtaking lane, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to avehicle in front.
R you switch on the respective turn signals.
R DISTRONIC PLUS does not detect adanger
of collision.
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis- Driving systems

ebetween your vehicl eand the vehicl ein
front become stoo small.
i Whe nchanging lanes, DISTRONIC PLUS
monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles.

i The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case if, while following a
vehicle, DISTRONIC PLUS is active and you:
R approach or drive around aroundabout
R approach aT-junction
R turn off at amotorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. Example: roundabout
The current speed is maintained:
R
approximately ten seconds before the
roundabout/T-junction and for approx-
imately 1.5seconds when driving on the
roundabout
R approximately twelve seconds before
reaching amotorway exit and approx-
imately four seconds after the motorway
exit Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
WARNING
Never get out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must also never be oper-
ated, activated or deactivated by apassenger
or from outside the vehicle.
DISTRONIC PLUS does not replace the park-
ing brake and must not be used for parking.
The DISTRONIC PLUS braking effect is can-
celled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is amalfunction in the system or an
interruption in the power supply,e .g. bat-
tery failure.
R the electrical system in the engine com-
partment,t he battery or the fuses are tam-
pered with.
R the battery is disconnected.
If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If DISTRONIC PLUS detectst hat 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 Depending on the specified minimum dis-
tance, your vehicle will come to astandstill
at as ufficient distance behind the vehicle
in front.T he specified minimum distance is
set using the control on the cruise control
lever. 174
Driving systemsDriving and parking

Setting the specified minimum distance
You can set the specified minimum distance
for DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in
front,d ependent on vehicle speed. You can
see this distance in the multifunction display
(Y page 176).
X To increase: turn control=in direc-
tion ;.
DISTRONIC PLUS then maintains agreater
distance between your vehicle and the
vehicle in front.
X To decrease: turn control=in direc-
tion :.
DISTRONIC PLUS then maintains ashorter
distance between your vehicle and the
vehicle in front.
i Make sure that you maintain asufficient
and safe distance from the vehicle in front.
Adjust the distance to the vehicle in front if
necessary. Displaying DISTRONIC PLUS in the
speedometer When DISTRONIC PLUS is activated, one or
two segments
;in the set speed range light
up.
i For design reasons, the speed displayed
in the speedometer may differ slightly from
the speed set for DISTRONIC PLUS.

Tips for driving with DISTRONIC PLUS General notes
The following contains description
sofcertain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles travelling on
adifferent line DISTRONIC PLUS may not detec
tvehicles
travelling on adifferent line. The distance to
the vehicle in fron twill be too short.
Other vehicles changing lane DISTRONIC PLUS has not yet detected the
vehicle cuttin
gin. The distanc etothis vehicle
will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the carriage-
way, because of its narrow width
.The dis-
tance to the vehicle in front will be too short. 178
Driving systemsDriving and parking

Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turn sacorner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally. HOLD function

WARNING
If you have selected "Comfort tuning", the
vehicle will be lowered if you lock it within
60 seconds of the engine being switched off.
Make sure, therefore, that nobody is in the
vicinit yofthe wheel housing or under the
vehicle when you lock the vehicle. Otherwise,
limbs could become trapped.
! The vehicle is lowered by about 15 mm if:
R you have selected "Comfort tuning"
R you switch off the engine and
R you lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that
it does not make contact with the kerb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
Your vehicle regulates its height automati-
cally. All-round level control ensures the best
possible suspension and constant ground
clearance, even with aladen vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. Driving systems
