Tips for driving with DISTRONIC PLUS
Important safety notes
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.
WARNING
The DISTRONIC PLUS works to maintain the 
speed selected by the driver unless a moving 
obstacle proceeding directly ahead of it in the 
same travel direction is detected (e.g. following another vehicle ahead of you 
at your 
set distance).
This means that:
• Your vehicle can pass another vehicle after 
you have changed lanes.
• While in a sharp turn or if the preceding 
vehicle is in a sharp turn, the DISTRONIC 
PLUS could lose sight of the preceding 
vehicle. Your vehicle could then accelerate 
to the previously selected speed.
The DISTRONIC PLUS regulates only the 
distance between your vehicle and those 
directly ahead of it. It may not register 
stationary objects in the road, e.g.:
• a stopped vehicle in a traffic jam
• a disabled vehicle
• an oncoming vehicle
The driver must always be alert, observe all 
traffic and intercede as required by means of 
steering or braking the vehicle.
WARNING
The DISTRONIC PLUS should not be used in 
snowy or icy road conditions.
Cornering, going into and coming out of a bend

The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late.
Vehicles traveling on a different line

DISTRONIC PLUS may not detect vehicles traveling 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 has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short.
Obstructions and stationary vehicles

DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these.
Crossing vehicles

DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.
