Other features of Active Distance Assist
DISTRONIC:
Adjusts the driving style depending on the
R
selected drive program (fuel-saving, comfort‐
able or dynamic) (
page 147)
→
Reacts to stationary vehicles in urban speed
R
ranges (except bicycles and motorcycles) if
conditions are sufficient to enable detection.
It also does not detect pedestrians.
Initiates rapid acceleration to the stored
R
speed, if the turn signal indicator is switched
on to change to the overtaking lane.
Takes one-sided overtaking restrictions into
R
account on motorways or on multi-lane roads
with separate carriageways.
Vehicles with Active Parking Assist: if the vehicle
has been braked to a standstill on multi-lane,
separate carriageways by Active Distance Assist
DISTRONIC, it can automatically follow the vehi‐
cle in front driving off again within 30 seconds. If
a critical situation is detected when driving off, a
visual and acoustic warning is given indicating
that the driver must now take control of the vehi‐
cle. The vehicle is not accelerated any further.
Active Distance Assist DISTRONIC is only an aid.
The driver is responsible for keeping a safe dis‐
tance 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, for example:
In snow, rain, fog, heavy spray, if there is
R
glare, in direct sunlight or in greatly varying
light conditions.
The windscreen in the area of the camera is
R
dirty, misted up, damaged or covered.
If the radar sensors are dirty or covered.
R
On slippery roads, braking or accelerating
R
can cause the drive wheels to lose traction
and the vehicle could then skid.
In multi-storey car parks or on roads with
R
steep uphill or downhill gradients.
Do not use Active Distance Assist DISTRONIC in
these situations.
Driving and parking 177
& 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
R
considerably faster or slower than the
currently 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.
