R
On icy or slippery roads, braking or accelerat-
ing can cause the drive wheels to lose traction
and the vehicle could then skid.
R
Stationary objects are not detected if these
were not previously detected as moving.
R
On curves, target vehicles may be lost or not
recognized correctly. As a result, a target vehi-
cle is not used to regulate the speed which
may lead to unwanted acceleration.
Do not use Active Distance Assist DISTRONIC in
these situations.

WARNING
ARNING Risk of accident from accelera-
tion or braking by Active Distance Assist
DISTRONIC
Active Distance Assist DISTRONIC may accel-
erate or brake in the following cases, for exam-
ple:
R
If the vehicle pulls away using Active Dis-
tance Assist DISTRONIC.
R
If the stored speed is called up and is con-
siderably faster or slower than the cur-
rently driven speed.
R
If Active Distance Assist DISTRONIC no
longer detects a vehicle in front or does
not react to relevant objects.
#
Always carefully observe the tra c con-
ditions and be ready to brake at all times.
#
Take into account the tra c situation
before calling up the stored speed.

WARNING
ARNING Risk of accident due to insu -
cient deceleration by Active Distance
Assist DISTRONIC
Active Distance Assist DISTRONIC brakes your
vehicle with up to 50% of the possible deceler-
ation. If this deceleration is not su cient,
Active Distance Assist DISTRONIC alerts you
with a visual and acoustic warning.
#
Adjust your speed and maintain a suita-
ble distance from the vehicle in front.
#
Brake the vehicle yourself and/or take
evasive action.

WARNING
ARNING 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:
R
when driving on a di erent lane or when
changing lanes
R
to pedestrians, animals, bicycles or station-
ary vehicles, or unexpected obstacles
R
to complex tra c conditions
R
to oncoming vehicles and crossing tra c
As a result, Active Distance Assist DISTRONIC
may neither give warnings nor intervene in
such situations.
#
Always observe the tra c conditions
carefully and react accordingly.
Active Distance Assist DISTRONIC may not detect
narrow vehicles driving in front, e.g. motorcycles
and vehicles not traveling in line with your vehicle.
