Important safety notes G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time.
SPEEDTRONIC brakes automaticallysot hat
you do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. 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
wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
You can set avariableorp ermanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted (Y page 170) i
The speed indicated in the speedometer
may differ slightly from the limit speed
stored.

WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detec tnarro wvehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on adifferen tline. Therefore,
always pay attention to traffic condition seven
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise danger sin
time, cause an accident and injure yourself
and others. 170
Driving systemsDriving and parking

G
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

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
