minimum distance (Y page 172).
Pulling away and driving G
WARNING
When you step on the brake pedal, you switch
off the DISTRONIC PLUS except when the
vehicle is at a standstill. The DISTRONIC PLUS
will no longer brake your vehicle. You are
always responsible for maintaining a distance
fro mo thervehicles, observing road speeds
and braking well in advance. X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever toward
you 0024.
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 slowed down, it brakes your
vehicle. It maintains the preset distance to
the vehicle in front.
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.
Changing lanes G
WARNING
DISTRONI CPLUS and Active Blind Spot Assist
are only aids 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 yours urroundings.
Otherwise, you may fail to recognize dangers
in time, cause an acciden tand injure yourself
and others.
If you wish to change to the passing lane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane),
DISTRONIC PLU Ssupports you if:
R you are driving faster than 40mph
(60 km/h).
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front. 170
Driving systemsDriving and pa
rking 

R
you have switched on the corresponding
tur ns ignal.
R DISTRONIC PLUS does not detect a danger
of collision.
If these conditions are fulfilled, your vehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in front becomes too small.
Stopping G
WARNING
Neve rget out of the vehicle when DISTRONIC
PLUS is activated.
DISTRONIC PLUS must also never be
operated, activated or deactivated by a
passenger or from outside the vehicle.
DISTRONIC PLUS does not replace the
electric parking brake and must not be used
for parking.
The DISTRONIC PLUS braking effect is
canceled and the vehicle can start moving if:
R DISTRONIC PLUS is deactivated using the
cruise control lever.
R you accelerate.
R there is a malfunction in the system or an
interruption in the power supply, e.g.
battery failure.
R the electrical system in the engine
compartment, the battery or the fuses are
tampered 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 detects that the vehicle
in fron tis 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. After a time, the electric parking brake
secures the vehicle and relieves the service
brake. Depending on the specified minimum
distance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front.T
he specified minimum distance is set
using the control on the cruise control lever.
The electric parking brake automatically
secures the vehicle if DISTRONIC PLUS is
activated and:
R the driver's door is open and the driver's
seat belt is unfastened.
R the engine is switched off, unless it is
automatically switched off by the ECO
start/stop function.
R the hood is opened.
R a system malfunction occurs.
R the power supply is not sufficient.

Tips for driving with DISTRONIC PLUS Important safety notes
G
WARNING
The DISTRONIC PLUS works to maintain the
speed selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance).
This means that:
R Your vehicle can pass another vehicle after
you have changed lanes.
R While in a sharp turn or if the preceding
vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding
vehicle. Your vehicle could then accelerate
to the previously selected speed.
The DISTRONIC PLUS regulates only the
distance between your vehicle and those
directly ahead of it. It may not register
stationary objects in the road, e.g.:
R a stopped vehicle in a traffic jam
R a disabled vehicle
R an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means of
steering or braking the vehicle. G
WARNING
The DISTRONIC PLUS should not be used in
snowy or icy road conditions.

WARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
