160 Driving and parking
distance to the vehicle in front and the set speed.
Speed and distance are set and stored on the
steering wheel. The speed can be set in the range
between 20 km/h and 160 km/h or between
20 km/h and the vehicle's maximum speed.
Other features of Active Distance Assist
DISTRONIC:
Depending on the preselected distance,
R
DISTRONIC intervenes either dynamically
(short distance) or to save fuel (long dis‐
tance).
Depending on the vehicle mass detected, the
R
dynamics of the DISTRONIC intervention are
reduced.
Rapid acceleration to the stored speed is initi‐
R
ated if the turn signal indicator is switched on
to change to the overtaking lane.
Active Distance Assist DISTRONIC is only an aid.
The driver is responsible for the distance to the
vehicle in front, for vehicle speed and for braking
in good time.
System limitations
The system may be impaired or may not function
in the following instances:
The radar sensors are affected by snow, rain,
R
fog, heavy spray, glare, direct sunlight or
greatly varying light conditions.
The radar sensors may malfunction in multi-
R
storey car parks or on roads with steep uphill
or downhill gradients.
If the radar sensors are dirty or covered.
R
On icy or slippery roads, braking or accelerat‐
R
ing can cause the drive wheels to lose trac‐
tion and the vehicle could then skid.
Stationary objects are not detected if these
R
were not previously detected as moving.
On bends, target vehicles may be lost or not
R
recognised correctly. As a result, a target
vehicle is not used to regulate the speed
which may lead to unwanted acceleration.
Do not use Active Distance Assist DISTRONIC in
these situations.
& WARNING Risk of accident from acceler‐
ation or braking by Active Distance Assist
DISTRONIC
Active Distance Assist DISTRONIC may accel‐
erate or brake in the following cases, for
example:
If the vehicle pulls away using Active Dis‐
R
tance Assist DISTRONIC.
If the stored speed is called up and is con‐
R
siderably faster or slower than the cur‐
rently driven speed.
If Active Distance Assist DISTRONIC no
R
longer detects a vehicle in front or does
not react to relevant objects.
Always carefully observe the traffic con‐
#
ditions and be ready to brake at all
times.
Take into account the traffic situation
#
before calling up the stored speed.
& WARNING Risk of accident due to insuf‐
ficient deceleration by Active Distance
Assist DISTRONIC
Active Distance Assist DISTRONIC brakes
your vehicle with up to 50 % of the maximum
possible deceleration. If this deceleration is
not sufficient, Active Distance Assist
DISTRONIC alerts you with a visual and
acoustic warning.
In these cases, adjust your speed and
#
keep a sufficient distance.
Brake the vehicle yourself and/or take
#
evasive action.
& WARNING Risk of accident if detection
function of Active Distance Assist
DISTRONIC is impaired
Active Distance Assist DISTRONIC does not
react or has a limited reaction:
when driving on a different lane or when
R
changing lanes
to pedestrians, animals, bicycles or sta‐
R
tionary vehicles, or unexpected obstacles
to complex traffic conditions
R
to oncoming vehicles and crossing traffic
R
As a result, Active Distance Assist DISTRONIC
may neither give warnings nor intervene in
such situations.
