sound and the distance warning lamp will lightup in the instrument cluster. Brake immedi-ately in order to increase the distance to thevehicle in front or take evasive action providedit is safe to do so.
Active Distance Assist DISTRONIC operates inthe speed range between 0 mph (0 km/h) and120 mph (200 km/h).
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden. By doing so,you will make use of the braking effect of theengine. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.
Do not use Active Distance Assist DISTRONICon roads with steep gradients.
For Active Distance Assist DISTRONIC toassist you when driving, the radar sensor sys-tem must be operational.
As Active Distance Assist DISTRONIC trans-mits radar waves, it can resemble the radardetectors of the responsible authorities. Youcan refer to the relevant chapter in the Opera-tor's Manual if questions are asked about this.

Important safety notes
GWARNING
Active Distance Assist DISTRONIC does not
react to:
Rpeople or animals
Rstationary objects in the road, e.g. stop-
ped or parked vehicles
Roncoming vehicles and crossing traffic
As a result, Active Distance Assist
DISTRONIC may neither give warnings nor
intervene in such situations. There is a risk
of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
GWARNING
Active Distance Assist DISTRONIC cannot
always clearly identify other road users and
complex traffic situations.
In such cases, Active Distance Assist
DISTRONIC can:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene
Raccelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Active Distance Assist
DISTRONIC warns you.
GWARNING
Active Distance Assist DISTRONIC brakes
your vehicle with up to 50% of the maximum
possible deceleration. If this deceleration is
not sufficient, Active Distance Assist
DISTRONIC alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Adjust your speed in these cases and main-
tain sufficient distance.
Apply the brakes yourself and/or take eva-
sive action.

Active Distance Assist DISTRONIC can neitherreduce the risk of an accident if you fail toadapt your driving style, nor override the lawsof physics. Active Distance Assist DISTRONICcannot take into account road, weather or traf-fic conditions. Active Distance AssistDISTRONIC is only an aid. You are responsiblefor the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.
Do not use Active Distance Assist DISTRONIC:
RIn road and traffic conditions which do notallow you to maintain a constant speed, e.g.in heavy traffic or on winding roads
ROn slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skid
RIn poor visibility, e.g. due to fog, heavy rainor snow
Active Distance Assist DISTRONIC may notdetect narrow vehicles driving in front, e.g.motorcycles, or vehicles driving in a staggeredformation.
In particular, the detection of obstacles can beimpaired if:
RThere is dirt on the sensors or anything elsecovering the sensors
RThere is snow or heavy rain
RThere is interference by other radar sources
RThere are strong radar reflections, for exam-ple in parking garages
If Active Distance Assist DISTRONIC no longerdetects a vehicle in front, Distance PilotDISTRONIC may unexpectedly accelerate tothe speed stored.
This speed may:
RBe too high if you are driving in a turninglane or an exit lane
RBe so high when driving in the right-handlane that you overtake vehicles in the left-hand lane
RBe so high in the left lane that you passvehicles driving on the right
If there is a change of drivers, advise the newdriver of the speed stored.

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).

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.

4MATIC
!Never tow the vehicle with one axle raised.This may damage the differential. Damageof this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels mustremain either on the ground or be fullyraised. Observe the instructions for towingthe vehicle with all wheels in full contactwith the ground.
4MATIC, together with ESP®, improves thetraction of your vehicle whenever a drivewheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATICcan neither reduce the risk of accident noroverride the laws of physics. 4MATIC cannottake account of road, weather and traffic con-ditions. 4MATIC is only an aid. You are respon-sible for the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far asnecessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximumeffect of 4MATIC can only be achieved if youuse winter tires (M+S tires), with snowchains if necessary.
