MERCEDES-BENZ GLC 2019 Owners Manual

For safety reasons, Mercedes-Benz recom-mends only installing the following brake disksand brake pads/linings:
Rbrake disks that have been approved byMercedes-Benz
Rbrake pads/linings that have been approvedby Mercedes-Benz or that are of an equivalentstandard of quality
Other brake disks or brake pads/linings cancompromise the safety of your vehicle.
Always replace all brake disks and brake pads/linings on an axle at the same time. Alwaysinstall new brake pads/linings when replacingbrake disks.
The vehicle is equipped with lightweight brakedisks to which the wheel assembly with rim andthreaded connection is matched.
The use of brake disks other than thoseapproved by Mercedes-Benz can change thetrack width and is subject to approval, if appli-cable.
Shock-type loads when handling the brakediscs, such as when changing wheels, can leadto a reduction in comfort when driving with light-weight brake discs. Avoid shock-type loads onthe lightweight brake disks, particularly on thebrake plate.
Mercedes-Benz recommends that you only usebrake fluid that has been specially approved foryour vehicle by Mercedes-Benz, or which corre-sponds to an equivalent quality standard. Brakefluid which has not been approved forMercedes-Benz vehicles or which is not of anequivalent quality could affect your vehicle'soperating safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring, even if:
Ryou drive at low speeds
Rthe tires have adequate tread depth
For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Bear in mind that vehicles traveling in frontor in the opposite direction create waves. Thismay cause the maximum permissible waterdepth to be exceeded.
Failure to observe these notes may result indamage to the engine, electrical systems andtransmission.
If you have to drive on stretches of road on whichwater has collected, please bear in mind that:
Rin the case of standing water, the water levelmay be no higher than the lower edge of thevehicle body
Ryou should drive no faster than walking pace
Winter driving
GWARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-faces. Avoid sudden acceleration, steering and

braking maneuvers. Do not use cruise control orActive Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning device andis therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especially inwooded areas or on bridges. The vehicle couldskid if you fail to adapt your driving style. Alwaysadapt your driving style and drive at a speed tosuit the prevailing weather conditions.
You should pay special attention to road condi-tions when temperatures are around freezingpoint.

Cruise control
General notes
Cruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. Change into a lower
gear in good time on long and steep downhillgradients. This is especially important if thevehicle is laden or towing a trailer. 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.
Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
Important safety notes
Cruise control can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Cruise control can-not take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for maintaining a safedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy 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
Rwhen there is poor visibility, e.g. due to fog,heavy rain or snow
If there is a change of drivers, advise the newdriver of the speed stored.
iThe speed indicated in the speedometermay differ slightly from the speed stored.

Active Distance Assist DISTRONIC
General notes
Active Distance Assist DISTRONIC regulates thespeed and automatically helps you maintain thedistance from the vehicle detected in front.Vehicles are detected with the aid of the radarsensor system. Active Distance AssistDISTRONIC brakes automatically so that the setspeed is not exceeded.
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden. By doing so, youwill make use of the braking effect of the engine.This relieves the load on the brake system andprevents the brakes from overheating and wear-ing too quickly.
If Active Distance Assist DISTRONIC detectsthat there is a risk of a collision with the vehiclein front, you will be warned visually and audibly.Active Distance Assist DISTRONIC cannot pre-vent a collision without your intervention. Anintermittent warning tone will then sound andthe distance warning lamp will light up in theinstrument cluster. Brake immediately in orderto increase the distance to the vehicle in front ortake evasive action provided it is safe to do so.
Active Distance Assist DISTRONIC operates inthe speed range between 0 mph(0 km/h) and120 mph (200 km/h).
Do not use Active Distance Assist DISTRONICwhile driving on roads with steep gradients.
As Active Distance Assist DISTRONIC transmitsradar waves, it can resemble the radar detectorsof the responsible authorities. You can refer tothe relevant chapter in the Operator's Manual ifquestions are asked about this.

Active Distance Assist DISTRONIC can neitherreduce the risk of an accident if you fail to adaptyour driving style, nor override the laws of phys-ics. Active Distance Assist DISTRONIC cannottake into account road, weather or traffic con-ditions. Active Distance Assist DISTRONIC isonly an aid. You are responsible for maintaininga safe distance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use Active Distance Assist DISTRONIC:
RIn road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy 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 rain orsnow
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 Pilot
DISTRONIC may unexpectedly accelerate to thespeed stored.
This speed may:
RBe too high if you are driving in a turning laneor an exit lane
Rbe so high in the right lane that you pass vehi-cles driving on the left (in countries wherethey drive on the right)

Activation conditions
To activate Active Distance Assist DISTRONIC,the following conditions must be fulfilled:
Rthe engine must be started. It may take up totwo minutes of driving before Active DistanceAssist DISTRONIC is ready for use.
Rthe electric parking brake must be released.
RESP®must be activated, but not interveningat present.
RParking Pilot must not be activated.
Rthe transmission must be in position[.
Rthe driver's door must be closed when youshift the transmission from position]to[or your seat belt must be fastened.
Rthe front-passenger door and rear doors mustbe closed.
Rthe vehicle must not slide.
Activating
XBriefly pull the cruise control lever towardsyou

If Active Distance Assist DISTRONIC detects afaster-moving vehicle in front, it increases thedriving speed to the set speed.
Selecting the drive program
Active Distance Assist DISTRONIC supports asporty driving style when you have selected theSorS+, drive program (Ypage 145). Accelera-tion behind the vehicle in front or to the setspeed is then noticeably more dynamic. If youhave selected theCorEdriving program, thevehicle accelerates more gently. This setting isrecommended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane Active Dis-tance Assist DISTRONIC supports you if:
Ryou are driving faster than 45 mph (70 km/h)
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 distancebetween your vehicle and the vehicle in frontbecomes too small.
When you change lanes, Active Distance AssistDISTRONIC monitors the left lane on left-hand-drive vehicles or the right lane on right-hand-drive vehicles.
Stopping
GWARNING
If you leave the driver's seat when the vehicle
is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
Rif there is a malfunction in the system or in
the voltage supply
Rif Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
Rif the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
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 167).
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.
After a time, the electric parking brake securesthe vehicle and relieves the service brake.
Depending on the specified minimum distance,your vehicle will come to a standstill at a suffi-cient distance behind the vehicle in front. Thespecified minimum distance is set using thecontrol on the cruise control lever.
When Active Distance Assist DISTRONIC is acti-vated, the transmission is shifted automaticallyto 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/stopfunction
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 be shifted to position]automatically.

iIf you accelerate to overtake, Active Dis-tance Assist DISTRONIC adjusts the vehicle'sspeed to the last speed stored after you havefinished overtaking.
Setting a specified minimum distance
You can set the specified minimum distance forActive Distance Assist DISTRONIC by varyingthe time span between one and two seconds.This determines the distance that Active Dis-tance Assist DISTRONIC is to maintain from thevehicle in front, depending on the road speed.You can see this distance in the multifunctiondisplay (Ypage 166).
Make sure that you maintain the minimum dis-tance to the vehicle in front as required by law.Adjust the distance to the vehicle in front if nec-essary.

RCrossing vehicles: Active Distance AssistDISTRONIC may mistakenly detect vehiclesthat are crossing your lane. Activating ActiveDistance Assist DISTRONIC at, for example, atraffic light with crossing traffic could causeyour vehicle to pull away at the wrong time.
In such situations, brake if necessary. ActiveDistance Assist DISTRONIC will then be deacti-vated.
Active Distance Assist DISTRONIC with
Active Steering Assist
General notes
Active Distance Assist DISTRONIC with ActiveSteering Assist aids you in keeping the vehicle inthe center of the driving lane by means of mod-erate steering interventions in a speed rangefrom 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle bymeans of multifunction cameraC, which ismounted at the top of the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),Active Steering Assist focuses on the vehicle infront, taking into account lane markings, e.g.when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),Active Steering Assist focuses on clear lanemarkings (left and right), focusing on the vehiclein front only if clear lane markings are not pres-ent.
If these conditions are not present, Active Steer-ing Assist cannot provide assistance.
Active Distance Assist DISTRONIC must beactive in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with ActiveSteering Assist can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Active DistanceAssist DISTRONIC with Active Steering Assistcannot take into account road, weather or trafficconditions. Active Distance Assist DISTRONICwith Active Steering Assist is only an aid. You areresponsible for maintaining a safe distance tothe vehicle in front, for vehicle speed, for brak-ing in good time and for staying in lane.
Active Distance Assist DISTRONIC with ActiveSteering Assist does not detect road and trafficconditions and does not detect all road users. Ifyou are following a vehicle which is drivingtowards the edge of the road, your vehicle couldcome into contact with the curb or other roadboundaries. Be particularly aware of other roadusers, e.g. cyclists, that are directly next to yourvehicle.
Obstacles such as traffic pylons at roadworks onthe lane or projecting out into the lane are notdetected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.
Active Distance Assist DISTRONIC with ActiveSteering Assist cannot continuously keep yourvehicle in lane. In some cases, steering inter-vention is not sufficient to bring the vehicle backto the lane. In such cases, you must steer thevehicle yourself to ensure that it does not leavethe lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
