2019 MERCEDES-BENZ SLC parking brake

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.
Cruise control lever
XTo increase:turn control

iThe last speed stored remains stored untilyou switch off the engine.
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.
Active Distance Assist DISTRONIC is automati-cally deactivated if:
Ryou engage the electric parking brake or ifthe vehicle is automatically secured with theelectric parking brake
RESP®intervenes or you deactivate ESP®
Rthe transmission is in position],^or\\
Ryou pull the cruise control lever towards youin order to pull away and the front-passenger door is open
Ryou activate Active Parking Assist
Rthe vehicle is skidding
If Active Distance Assist DISTRONIC is deacti-vated automatically, you will hear a warningtone. TheActive Distance Assist OffActive Distance Assist Offmessage will appear on the multifunction dis-play for approximately five seconds.
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
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

Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronicparking aid with ultrasound. It monitors thearea around your vehicle using six sensors inthe front bumper and four sensors in the rearbumper. Parking Assist PARKTRONIC visuallyand audibly indicates the distance betweenyour vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It isnot a replacement for your attention to yourimmediate surroundings. You are alwaysresponsible for safe maneuvering, parking andexiting a parking space. Make sure that thereare no persons, animals or objects in themaneuvering area when you are maneuveringor parking.
!When parking, pay particular attention toobjects above or below the sensors, such asflower pots or trailer drawbars.PARKTRONIC does not detect such objectswhen they are in the immediate vicinity ofthe vehicle. You could damage the vehicleor the objects.
The sensors may not detect snow and otherobjects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic carwash, the compressed-air brakes on a truckor a pneumatic drill could causePARKTRONIC to malfunction.
PARKTRONIC may not function correctly onuneven terrain.
Parking Assist PARKTRONIC is activated auto-matically when you:
Rswitch on the ignition
Rshift the transmission to position[,^or\\
Rrelease the electric parking brake

Always pay particular attention to the traffic
situation and keep within the lane, espe-
cially if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, LaneKeeping Assist can neither reduce the risk ofan accident nor override the laws of physics.Lane Keeping Assist cannot take into accountthe road, traffic and weather conditions. LaneKeeping Assist is merely an aid. You areresponsible for the distance to the vehicle infront, for vehicle speed, for braking in goodtime and for staying in your lane.
The Lane Keeping Assist does not keep thevehicle in the lane.
The system may be impaired or may not func-tion if:
Rthere is poor visibility, e.g. due to insuffi-cient illumination of the road, or due tosnow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,the sun or reflections (e.g. when the roadsurface is wet)
Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in thevicinity of the camera
Rthere are no, several or unclear lane mark-ings for a lane, e.g. in areas with road con-struction work
Rthe lane markings are worn away, dark orcovered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is toosmall and the lane markings thus cannot bedetected
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
Switching on Lane Keeping Assist
XSwitch on Lane Keeping Assist using the on-board computer; to do so, selectStandardStandardorAdaptiveAdaptive(Ypage 175).If you drive at speeds above 40 mph(60 km/h) and lane markings are detected,the lines in the assistance graphics display(Ypage 175) are shown in green. LaneKeeping Assist is ready for use.
Standard
IfStandardStandardis selected, no warning vibrationoccurs if:
Ryou switch on the turn signals. In this event,the warnings are suppressed for a certainperiod of time
Ra driving safety system intervenes, such as
ABS, BAS or ESP®
Adaptive
WhenAdaptiveAdaptiveis selected, no warning vibra-tion occurs if:
Ryou switch on the turn signals. In this event,the warnings are suppressed for a certainperiod of time
Ra driving safety system intervenes, e.g. ABS,
BAS or ESP®
Ryou accelerate hard, e.g. kickdown
Ryou brake hard
Ryou steer actively, e.g. swerve to avoid anobstacle or change lanes quickly
Ryou cut the corner on a sharp bend
In order that you are warned only when neces-sary and in good time if you cross the lanemarking, the system recognizes certain condi-tions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on abend
Rthe road has very wide lanes, e.g. a freeway
Rthe system recognizes solid lane markings
The warning vibration occurs later if:
Rthe road has narrow lanes
Ryou cut the corner on a bend
