i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into a
lower gear in good time on long and steep down-
hill gradients. Take particular note of this when
driving a laden vehicle. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear- ing too quickly. If you need additional braking,
depress the brake pedal repeatedly rather than continuously.
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather 158
Driving systemsDriving and parking

or traffic conditions. SPEEDTRONIC is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane.
If there is a change of drivers, advise the new
driver of the speed stored.
You can set a variable or permanent limit speed:
R variable for speed limits, e.g. in built-up areas
R permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted

Driving systemsDriving and parking

To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of an accident
nor override the laws of physics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid. You are responsible for the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections, for
example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left (in countries where
they drive on the right)
R be so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)

Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again. X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle cruise speed to the
previously stored value. Driving systems

Driving with DISTRONIC PLUS
Pulling away and driving
X
If you want to pull away with DISTRONIC
PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you :.
or X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front.
If no vehicle is detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ- ent line from another vehicle. The vehicle then
brakes automatically.
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
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style when you select the Sor Mdrive program
(Y page 143). Acceleration behind the vehicle in
front or to the set speed is then noticeably more dynamic. If you have selected the Edrive pro-
gram, the vehicle accelerates more gently. This
setting is recommended in stop-start traffic. Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the distance
to a vehicle in front
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle is accel- erated. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane
on left-hand-drive vehicles or the right lane on right-hand-drive vehicles.
Vehicles with COMAND Online Example: roundabout
i
The following function is not operational in
all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations. This is the case if,
while following a vehicle, DISTRONIC PLUS is
active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler- 164

msDriving and parking

ate. This is based on the current map data in the
navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
above 80 km/h. The driving speed is adjusted to
the speed of the queue of vehicles in the adja-
cent lane to the left.
i Prevention of overtaking on the right applies
to countries where traffic drives on the right.
In countries where traffic drives on the left,
overtaking on the left is prevented accord-
ingly.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
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.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating DISTRONIC PLUS (Y page 167).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. When DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position
