Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the vehi-
cle is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictionsprohibit the driver from using a mobile phonewhile driving a vehicle.
If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.

Driving and parking

To activate Active Distance Assist DISTRONIC,all the following conditions must be fulfilled:
Rthe engine must be started. It may take upto two minutes of driving before Active Dis-tance Assist DISTRONIC is ready for use.
Rthe electric parking brake must be released.
RESP®must be active, but not intervening.
RActive Parking Assist must not be activated.
Rthe transmission must be in position[.
Rthe driver's door must be closed when youshift from]to[or your seat belt mustbe fastened.
Rthe front-passenger door must be closed.
RDSR must be deactivated.
Rthe vehicle must not skid.
Activating
XBriefly pull the cruise control lever towardsyou

Selecting the drive program
Active Distance Assist DISTRONIC supports asporty driving style when you select theS+drive program (Ypage 138) or the manualdrive program (Ypage 140). Accelerationbehind the vehicle in front or to the set speedis then noticeably more dynamic. If you haveselected theE(Mercedes-AMG vehicles:C)drive program, the vehicle accelerates moregently. This setting is recommended in stop-and-start traffic.
Changing lanes
If you want to change to the overtaking laneon multi-lane roads, Active Distance AssistDISTRONIC supports you if:
Ryou are driving faster than 45 mph(70 km/h)
RActive Distance Assist DISTRONIC is main-taining the distance to a vehicle in front
Ryou switch on the appropriate turn signal
RActive Distance Assist DISTRONIC does notcurrently detect a danger of collision
If these conditions are fulfilled, your vehicle isaccelerated. Acceleration will be interrupted ifchanging lanes takes too long or if the dis-tance between your vehicle and the vehicle infront becomes too small.
Stopping
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 insufficient.
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.
XPress the cruise control lever upCfor ahigher speed or downDfor a lower speed.
XTo adjust the set speed in 1 mph incre-ments (1 km/h increments):briefly pushthe cruise control lever upCor downDtothe pressure point.The last stored speed increases or decrea-ses in 1 mph (1 km/h) increments.
XTo adjust the set speed in 5 mph incre-ments (10 km/h increments):briefly pushthe cruise control lever upCor downDbeyond the pressure point.The last stored speed increases or decrea-ses in 5 mph (10 km/h) increments.
iActive Distance Assist DISTRONIC is notdeactivated if you depress the acceleratorpedal. If you accelerate to overtake, ActiveDistance Assist DISTRONIC adjusts the vehi-cle's speed to the last speed stored, afteryou have finished overtaking.
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 164).

in front on the edge of the road because ofits narrow width. The distance to the vehiclein front will be too short.
RObstacles and stationary vehicles: ActiveDistance Assist DISTRONIC does not brakefor obstacles or stationary vehicles. If, forexample, the detected vehicle turns a cor-ner and an obstacle or stationary vehicle isrevealed, Active Distance Assist DISTRONICwill not brake for them.
RActive Distance Assist DISTRONIC may mis-takenly detect vehicles that are crossingyour lane. If you activate Active DistanceAssist DISTRONIC under the following condi-tions, the vehicle could pull away uninten-tionally:
-at traffic lights with crossing traffic, forexample
-if there is a vehicle in front, after a cross-ing, with the HOLD function activated
In such situations, brake if necessary. ActiveDistance Assist DISTRONIC will then be deacti-vated.
HOLD function
General notes
The HOLD function can assist the driver in thefollowing situations:
RWhen pulling away, especially on steepslopes
RWhen maneuvering on steep slopes
RWhen waiting in traffic
The vehicle is kept stationary without thedriver having to depress the brake pedal.
The braking effect is canceled and the HOLDfunction deactivated when you depress theaccelerator pedal to pull away.
Important safety notes
GWARNING
If the vehicle is only braked using the HOLD
function, the vehicle may roll away in the fol-
lowing situations when you leave the vehi-
cle:
Rif there is a malfunction in the system or
in the voltage supply
Rif the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant
There is a risk of an accident.
Always deactivate the HOLD function and
secure the vehicle against rolling away
before you leave it.
!When Active Distance Assist DISTRONICor the HOLD function is activated, the vehi-cle brakes automatically in certain situa-tions.
To avoid damage to the vehicle, deactivateActive Distance Assist DISTRONIC and theHOLD function in the following or similar sit-uations:
Rwhen towing the vehicle
Rin the car wash
Deactivate the HOLD function (Ypage 166).
Activation conditions
You can activate the HOLD function if:
Rthe vehicle is stationary
Rthe engine is running or if it has been auto-matically switched off by the ECO start/stop function
Rthe driver's door is closed or your seat beltis fastened
Rthe electric parking brake is released
RActive Distance Assist DISTRONIC is deacti-vated
Rthe transmission is in position[,^or\\on vehicles with automatic transmission

Start-off Assist (except Mercedes-
AMG vehicles)
Important safety notes
GWARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP®is deactivated, there is a greater dan-
ger of skidding and having an accident.
Make sure that no persons or obstacles are
in the vicinity of the vehicle.
Start-off assist enables optimum accelerationfrom a standstill. For this, a suitably high-griproad surface is required and the vehicle andtires must be in good working order.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-tems (Ypage 60).
Be sure to read the safety notes and informa-
tion on ESP®(Ypage 63).
