WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognise sthe vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverted ,e.g. at roadworks on amotor-
way
DISTRONIC PLUS otherwise maintains the
current spee dset by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the road sare slippery ,snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicl ecould
start to skid.
R if the sensors are dirty or there is poor vis-
ibility ,e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4m/s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detect sarisk of collision
with avehicle in front, an intermittent warning
tones ounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brak etoavoidacollision. General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tanc
etot he vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
By doing so, you will make use of the braking
effec tofthe engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detectsas lower-moving
vehicle in front,y our vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 368).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 225) and operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on road swith
steep gradients. Driving systems

i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended message appears in the multifunction dis-
play. The set distanc etoaslower-moving

You will be driving at the speed you deter-
mine by the position of the accelerator
pedal.

X Press the cruise control lever repeatedly
up : or down =until the desired speed
is set.
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

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
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away ,especially on steep
slopes
R when manoeuvrin gonsteep slopes
R when waiting in traffic The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effec tiscancelled and the HOLD
function is deactivated when you depress the
accelerator pedal to pull away.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary.
R the engine is running or it has been auto-
matically switched off by the ECO start/
stop function.
R the driver's door is closed or your seat belt
is fastened.
R the parking brake is released.
R the bonnet is closed.
R the transmission is in position D,Ror N.
R DISTRONIC PLUS is deactivated.
Activating the HOLD function G
WARNING
The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate the HOLD function if the vehicle is
to be set in motion by other means (e.g. in a
car wash or by towing).
X Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal further
until ë appears in the multifunction dis-
play.
The HOLD function is activated. You can
release the brake pedal.
i If depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again. Driving systems

R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to aparking
space being measured inaccurately. R
pay attention to the PARKTRONIC
(Y page 186) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correc tit. Active Parking
Assist will then be cancelled.
R when transporting aload which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergenc yspare
wheel are fitted, you should not use Active
Parking Assist here either.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the wa yyourv ehicl eisp ositioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion and shape of the vehicles parked in

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 kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
