R you move the selector lever to Non vehi-
cles with automatic transmission* while

If cruise control is deactivated, you will hear
a warning tone. You see the Cruise con‐
trol off message in the multi-function dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Distronic Plus*
i Distronic Plus is not available in all coun-
tries.
Distronic Plus regulates the speed and auto-
matically maintains the distance to the vehi-
cle in front. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic Plus is only an aid designed to assist
driving. The driver is fully responsible for the
vehicle's distance from other vehicles, the
vehicle's speed and for braking in good time.
Distronic Plus does not react 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 detect narrow vehicles
driving in front, e.g. motorcycles, or vehicles
driving on a different line. Therefore, always
pay attention to traffic conditions even when
Distronic Plus is activated. Otherwise, you
may fail to recognise dangers in time, cause
an accident and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front. 140

G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
recognise or no longer recognises the vehicle
in front, do not activate Distronic or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at motorway/road-
way construction sites
Otherwise, Distronic Plus maintains the cur-
rent speed 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 roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
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. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 362).
If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h. Do not use Distronic Plus while driving on
roads with steep gradients. G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.

Pulling away
X
If the vehicle in front pulls away: 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.
Driving
If there is no vehicle in front, Distronic Plus
operates in the same way as cruise control.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front.
If Distronic Plus detects a faster-moving vehi-
cle in front, it increases the driving speed, but
only up to the stored speed. G
Risk of accident
If you depress the brake, Distronic Plus is
deactivated unless your vehicle is stationary.
Distronic Plus then no longer brakes your
vehicle. The driver is fully responsible for the
vehicle's distance from other vehicles, its
speed and for braking in good time.
Stopping G
Risk of accident
The Distronic Plus braking effect is cancelled
and the vehicle can start moving if:
R Distronic Plus is deactivated using the
cruise control lever
R you accelerate
R the system or the power supply is disrup-
ted, e.g. due to battery failure
R the electrical system in the engine com-
partment or the fuses have been tampered
with
R the battery is disconnected G
Risk of accident
Never get out of the vehicle when Distronic
Plus is activated.
Distronic Plus must never be operated or
deactivated by a passenger or from outside
the vehicle.
Distronic Plus does not replace the parking
brake and must not be used for parking.
If you wish to leave the vehicle or park it,
deactivate Distronic Plus and secure the vehi-
cle against rolling away.
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
brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle
in front. The specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
Vehicles with automatic transmission
with selector lever
When Distronic Plus is activated and the vehi-
cle is at a standstill, a warning message
appears in the multi-function display if:
R the driver's door is opened and you release
the seat belt.
R the engine is switched off, unless it is auto-
matically switched off by the ECO Start/
Stop function.
R the bonnet is opened.

Tips for driving with Distronic Plus The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic Plus is then
deactivated.
Cornering, entering and exiting a bend
The ability of Distronic Plus to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or too late. Vehicles travelling on a different line
Distronic Plus may not detect vehicles trav-
elling on a different line. The distance to the
vehicle in front will be too short.
Other vehicles changing lane
Distronic Plus has not detected the vehicle
cutting in yet. The distance to this vehicle will
be too short.
Narrow vehicles
Distronic Plus does not detect the vehicle in
front on the edge of the carriageway, because Driving systems
