In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
R accelerate or brake unexpectedly
There is arisk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes yourv ehicle with up
to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with avisuala nd
acoustic warning. There is arisk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- icallyinc ertain situations.
To avoid damage to the vehicle ,deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in ac ar wash
If you fail to adapt yourd riving style, DISTRONIC
PLUS can neither reduce the risk of an accident
nor override the lawsofp hysics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid.Y ou are responsible for the
distance to the vehicle in front, for vehicle
speed,f or braking in good time, and for staying
in lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed,e .g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheelstol ose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on
adifferent line.
In particular, the detection of obstacle scan be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radars ources
R the possibility of strong radarr eflections, for
example ,inmulti-storey car parks
If DISTRONIC PLUS no longer detects avehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for afilter lane or aslip road
R be so high in the right lane that you pass vehi-
cles driving on the left (left-hand drive coun-
tries)
R be so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is achange of drivers, advise the new
driver of the speed stored.

PARKTRONIC is then
deactivated and the indi-
cator lamp on the

X If problems persist, have PARKTRONIC checked at aqualified spe-
cialist workshop. Only the red segments in

ing displaysa re lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X
Clean the PARKTRONIC sensors (Y page 330).
X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X See if PARKTRONIC functions in adifferent location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems
