Rif the battery is disconnected
Rif the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
Further information on deactivating Active Dis-tance Assist DISTRONIC (Ypage 149).
If Active Distance Assist DISTRONIC detectsthat the vehicle in front is stopping, it brakesyour vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.
iAfter a time, the electric parking brakesecures the vehicle and relieves the servicebrake.
iDepending on the specified minimum dis-tance, your vehicle will come to a standstillat a sufficient distance behind the vehicle infront. The specified minimum distance is setusing the control on the cruise control lever.
When Active Distance Assist DISTRONIC isactivated, the transmission is shifted automati-cally to position]if:
Rthe driver's seat belt is not fastened and thedriver's door is open
Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stop function.
The electric parking brake is applied automati-cally if Active Distance Assist DISTRONIC isactive when the vehicle is stationary and:
Ra system malfunction occurs
Rthe power supply is not sufficient
If a malfunction occurs, the transmission mayalso shift to position]automatically.
Setting a speed
Keep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.
XTo adjust the set speed in 1 mph incre-ments (1 km/h increments):briefly pressthe cruise control lever upCto the pres-
sure point for a higher speed, or downDfor a lower speed.Every time the cruise control lever ispressed up or down, the last speed stored isincreased or reduced.
XTo adjust the set speed in 5 mph incre-ments (10 km/h increments):brieflypress the cruise control lever upCpast thepressure point for a higher speed, ordownDfor a lower speed.Every time the cruise control lever ispressed up or down, the last speed stored isincreased or reduced.
Setting a specified minimum distance
You can set the specified minimum distancefor Active Distance Assist DISTRONIC by vary-ing the time span between one and two sec-onds. This determines the distance that ActiveDistance Assist DISTRONIC is to maintain fromthe vehicle in front, depending on the roadspeed. You can see this distance in the multi-function display (Ypage 149).
The specified minimum distance can bechanged while Active Distance AssistDISTRONIC is switched on or off.
Make sure that you maintain a sufficiently safedistance from the vehicle in front. Adjust thedistance to the vehicle in front if necessary.

Tips for driving with Active Distance
Assist DISTRONIC
General notes
The following contains descriptions of certainroad and traffic conditions in which you mustbe particularly attentive. In such situations,brake if necessary. Active Distance AssistDISTRONIC will then be deactivated.
Cornering, going into and coming out of
a bend
The ability of Active Distance AssistDISTRONIC to detect vehicles when corneringis limited. Your vehicle may brake unexpect-edly or late.
Vehicles traveling on a different line
Active Distance Assist DISTRONIC may notdetect vehicles that are not driving in the mid-dle of their lane. The distance to the vehicle infront will be too short.
Other vehicles changing lanes
Active Distance Assist DISTRONIC has notdetected the vehicle cutting in yet. The dis-tance to this vehicle will be too short.
Narrow vehicles
150Driving systems
Driving and parking

Active Distance Assist DISTRONIC has not yetdetected the vehicle in front on the edge ofthe road because of its narrow width. The dis-tance to the vehicle in front will be too short.
Obstructions and stationary vehicles
Active Distance Assist DISTRONIC does notbrake for obstacles or stationary vehicles. If,for example, the detected vehicle turns a cor-ner and an obstacle or stationary vehicle isrevealed, Active Distance Assist DISTRONICwill not brake for them.
Crossing vehicles
Active Distance Assist DISTRONIC may mis-takenly detect vehicles that are crossing yourlane.
If you activate Active Distance AssistDISTRONIC under the following conditions, thevehicle could pull away unintentionally:
Rat traffic lights with crossing traffic, forexample
Rif there is a vehicle in front, after a crossing,with the HOLD function activated
