Pulling away and driving
Cruise control lever
If you depress the brake, DISTRONIC PLUS is deactivated unless your vehicle is stationary.
X If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you 0044, or up 0043or down 0087.
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 front has slowed down, it brakes your vehicle.
It maintains the preset distance to the vehicle
in front.
If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. DISTRONIC PLUS cannot pre-
vent a collision without your intervention. An
intermittent warning tone will then sound and
the distance warning lamp will light up in the instrument cluster. Brake immediately in
order to increase the distance from the vehi-
cle in front, or take evasive action, provided it
is safe to do so.
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
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), DIS-
TRONIC PLUS supports you if:
R you are driving faster than 40 mph
(60 km/h)
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front
R you have switched on the corresponding
turn signal
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 dis-
tance between your vehicle and the vehicle in front becomes too small.
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.
Deactivating DISTRONIC PLUS (Y page 189).
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
stationary and you do not need to depress the 186
Driving systemsDriving an
d parking

DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner 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
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent dam-
age to the vehicle, deactivate DISTRONIC
PLUS and the HOLD function in the follow-
ing or other similar situations:
R when towing the vehicle
R in the car wash

WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper- age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center. Before changing a fuse
X Secure the vehicle against rolling away
(Y page 171).
