2019 MERCEDES-BENZ GLC Owners Manual

If you select the reverse gear, Active Blind SpotAssist is not operational.
The brightness of the warning lamps is auto-matically adapted to the brightness of the sur-roundings.
When Active Blind Spot Assist is activated, grayradar waves propagating backward appear nextto the vehicle in the assistance display in themultifunction display. Above a speed of 20 mph(30 km/h), the color of the radar waves in theassistance display changes to greenD. ActiveBlind Spot Assist is then ready for use.
Collision warning from visual warning and
warning tone
If you switch on the turn signal to change lanesand a vehicle is detected in the side monitoringrange, you receive a visual warning and a warn-ing tone as a collision warning. You will thenhear a double warning tone and red warninglampCflashes. If the turn signal remains on,detected vehicles are indicated by the flashingof red warning lampC. No further warning tonesounds.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-eral collision in the monitoring range, a course-correcting brake application is carried out. Thisis meant to assist you in avoiding a collision.
GWARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,red warning lampCflashes in the exterior mir-ror and a double warning tone sounds. In addi-tion, a display underlining the danger of a sidecollision appears in the multifunction display.
In very rare cases, the system may make aninappropriate brake application. A course-cor-recting brake application may be interrupted atany time by countersteering slightly or acceler-ating.
The course-correcting brake application is avail-able in the speed range between 20 mph(30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-cor-recting brake application adapted to the drivingsituation occurs if:
Rthere are vehicles or obstacles, e.g. crashbarriers, located on both sides of your vehicle.
Ra vehicle approaches you too closely at theside.
Ryou have adopted a sporty driving style withhigh cornering speeds.
Ryou clearly brake or accelerate.
Ra driving safety system intervenes, e.g. ESP®
or PRE-SAFE®Brake.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area infront of your vehicle by means of multifunctioncameraCat the top of the windshield. Variousdifferent areas to the front, rear and side of yourvehicle are also monitored with the aid of theradar sensor system. Active Lane KeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally. If you do not react to the warning, alane-correcting application of the brakes canbring the vehicle back into the original lane.
This function is available in the range between40 mph and 120 mph (60 km/h and 200 km/h).
Important safety notes
If you fail to adapt your driving style, Active LaneKeeping Assist can neither reduce the risk of anaccident nor override the laws of physics. ActiveLane Keeping Assist cannot take account ofroad and weather conditions. It may not recog-nize traffic situations. Active Lane KeepingAssist is only an aid. You are responsible for thedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inyour lane.
Active Lane Keeping Assist cannot continuouslykeep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
Rneither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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
Rthe radar sensors in the front or rear bumpersor the radiator trim are dirty, e.g. obscured bysnow
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
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions onthe roadway
If no vehicle is detected in the adjacent lane andbroken lane markings are detected, no lane-cor-recting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel passesover a lane marking. It will warn you by means ofintermittent vibration in the steering wheel forup to 1.5 seconds.

Lane-correcting brake application
If you leave your lane, under certain circumstan-ces the vehicle will brake briefly on one side.This is meant to assist you in bringing the vehicleback to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
If a lane-correcting brake application occurs,displayCappears in the multifunction display.The brake application also slightly reduces vehi-cle speed.
A lane-correcting brake application can be madeafter driving over a lane marking recognized asbeing solid or broken. Before this, a warningmust be given by means of intermittent vibrationin the steering wheel. In addition, a lane withlane markings on both sides must have beendetected.
In the case of a broken lane marking beingdetected, a lane-correcting brake applicationcan only be made if a vehicle has been detectedin the adjacent lane. Oncoming vehicles, over-taking vehicles and vehicles in adjacent lanescan be detected.
A further lane-correcting brake application canonly occur after your vehicle has returned to theoriginal lane.
No lane-correcting brake application occurs if:
Ryou clearly and actively steer, brake or accel-erate
Ryou cut the corner on a sharp bend
Ryou have switched on the turn signal
Ra driving safety system intervenes, e.g. ESP®,
PRE-SAFE®Brake or Active Blind Spot Assist
Ryou have adopted a sporty driving style withhigh cornering speeds or high rates of accel-eration

Towing a trailer
When you attach a trailer, make sure you havecorrectly established the electrical connection.
This can be accomplished by checking the trailerlighting.
Towing a trailer
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the
ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Ypage 364).
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
!If you have a trailer tow hitch retrofitted,changes to the engine cooling system may benecessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.
The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.
202Towing a trailer
Driving an d parking

For more information, please contact a qualifiedspecialist workshop.
Please observe the manufacturer's operatinginstructions for the trailer coupling if a detach-able trailer coupling is used.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehiclecorrectly, the trailer could become detached.
Make sure that the following values are notexceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towingvehicle
Rthe maximum permissible gross vehicleweight of both the towing vehicle and thetrailer
The applicable permissible values, which mustnot be exceeded, can be found:
Rin the vehicle documents
Ron the type plate for the trailer
Ron the vehicle identification plate
If the values differ, the lowest value applies.
When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning circle
This could impair the handling characteristics.
When towing a trailer, always adjust your speedto the current road and weather conditions. Donot exceed the maximum permissible speed foryour vehicle/trailer combination.
Notes on towing a trailer
General notes
RDo not exceed the maximum permissiblespeed for vehicle/trailer combinations in therelevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling onyour vehicle.
Further information on availability and oninstallation is available from any authorizedMercedes-Benz Center.
RThe bumpers of your vehicle are not suitablefor installing detachable trailer couplings.
RDo not install hired trailer couplings or otherdetachable trailer couplings on the bumpersof your vehicle.
RIf you no longer need the ball coupling,remove it from the ball coupling recess. Thiswill reduce the risk of damage to the ball cou-pling.
When towing a trailer, set the tire pressure onthe rear axle of the towing vehicle for a maxi-mum load; see the tire pressure table in the fuelfiller flap (Ypage 348).
Please note that when towing a trailer, the fol-lowing driving systems have limited availabilityor are not available at all:
RPARKTRONIC (Ypage 179)
RBlind Spot Assist (Ypage 193)
RActive Lane Keeping Assist (Ypage 200)
On vehicles without level control, the height ofthe ball coupling will alter according to the loadplaced on the vehicle. If necessary, use a trailerwith a height-adjustable drawbar.
You will find permissible trailer loads under"Technical data" (Ypage 364).
Driving tips
Observe the information on ESP®trailer stabili-zation (Ypage 71) and on pulling away with atrailer (Ypage 135).
The maximum permissible speed for vehicle/trailer combinations depends on the type oftrailer. Before beginning the journey, check thetrailer's documents to see what the maximumpermitted speed is. Observe the maximum per-missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-mum permissible rear axle load is increasedwhen towing a trailer. See the "Technical data"section to find out whether this applies to yourvehicle (Ypage 365). In the event of increasedrear axle load, the vehicle/trailer combinationmay not exceed a maximum speed of 60 mph(100 km/h) for reasons concerning the operat-ing permit. This also applies in countries in
Towing a trailer203

Z

which the maximum permissible speed for vehi-cle/trailer combinations is above 60 mph(100 km/h).
When towing a trailer, your vehicle's handlingcharacteristics will be different in comparison towhen driving without a trailer and it will con-sume more fuel.
Shift to a lower gear on long and steep downhillgradients.
This also applies to:
Ractivated DISTRONIC PLUS
Ractivated cruise control
This will use the braking effect of the engine, sothat less braking will be required to maintain thespeed. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly. If you need additionalbraking, depress the brake pedal repeatedlyrather than continuously.
Driving tips
If the trailer swings from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
RMaintain a greater distance from the vehiclein front than when driving without a trailer.
RAvoid braking abruptly. If possible, brake gen-tly at first to allow the trailer to run on. Then,increase the braking force rapidly.
RThe values given for gradient-climbing capa-bilities from a standstill refer to sea level.When driving in mountainous areas, note thatthe power output of the engine and, conse-quently, the vehicle's gradient-climbing capa-bility, decreases with increasing altitude.
Installing the ball coupling
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving
and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
If the ball coupling is not installed and secured
correctly the trailer may come loose. There is
a risk of an accident.
Install and secure the ball coupling as descri-
bed in the ball coupling installation instruc-
tions. Make sure that the ball coupling is
installed and secured correctly before every
journey.
XPull protective capCin the direction of thearrow, out of the ball coupling recess.
XStow protective capCso that it cannot bethrown around.
XObserve the manufacturer's installationinstructions.
Observe the loading guidelines (Ypage 278)and the safety notes regarding stowagespaces (Ypage 278).
Coupling up a trailer
!Do not connect the trailer's brake system (iffeatured) to the hydraulic brake system of thetowing vehicle, as the latter is equipped withan anti-lock brake system. Doing so will resultin a loss of function of the brake systems ofboth the vehicle and the trailer.
XApply the vehicle's electric parking brakemanually.
XStart the engine.
XShift the transmission to position].
XVehicles with AIR BODY CONTROL:selecttheComfortdrive program.

XSwitch off the engine.
XClose the doors and tailgate.
XCouple up the trailer.
XEstablish the electrical connection betweenthe vehicle and the trailer.
XCheck that the trailer lighting system is work-ing.
XPush the combination switch upwards/down-wards and check whether the correspondingturn signal on the trailer flashes.
A trailer that is connected is recognized onlywhen the electrical connection is establishedcorrectly and when the lighting system is work-ing properly. The function of other systems alsodepends on this, for example:
RESP®
RPARKTRONIC
RActive Parking Assist
RActive Blind Spot Assist
RActive Lane Keeping Assist
Vehicles with AIR BODY CONTROL: if you coupleup a trailer, the vehicle always remains at high-way level. Observe the following note when cou-pling up a trailer:
RUnless highway level has been set manually,the vehicle is automatically lowered to high-way level. If a speed of 5 mph (8 km/h) hasbeen reached, this may be the case.
These restrictions apply to accessories that aresupplied with power via the trailer socket in yourvehicle, e.g. a rear bicycle rack.
Observe the maximum permissible trailerdimensions (width and length).
Most U.S. states and all Canadian provincesrequire by law:
RSafety chains between the towing vehicle andthe trailer. The chains should be cross-woundunder the trailer drawbar. They must be fas-tened to the vehicle's trailer coupling, not tothe bumper or the axle.
Leave enough play in the chains to make tightcornering possible.
RA separate brake system for certain types oftrailer.
RSafety switch for braked trailers. Check thespecific legal requirements applicable to yourstate.
If the trailer becomes detached from the tow-ing vehicle, the safety feature applies thetrailer brakes.
Towing a trailer
There are several legal requirements for towinga trailer, e.g. the maximum permissible speed.Make sure that your car/trailer combinationcomplies with the local regulations:
Rin your place of residence
Rat your destination
The police and local authorities can provide reli-able information.
To accumulate driving experience and accustomyourself to the new handling characteristics,practice the following at a location where thereis no traffic:
RCornering
RStopping
RBacking up
Check the following before the journey:
RTrailer tow hitch
RSafety switch for braked trailers
RSafety chains
RElectrical connections
RLighting system
RWheels and tires
RLoad securing
Adjust the exterior mirrors so that you have aclear view of the rear section of the trailer.
If the trailer is equipped with electronically con-trolled brakes, pull away carefully in the car/trailer combination. Brake manually using thebrake controller and check whether the brakesfunction correctly.
Regularly check that the load is secure.
When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning circle
Avoid sudden steering movements.
Avoid braking abruptly. If possible, brake gentlyat first to allow the trailer to run on. Then,increase the braking force rapidly.
Towing a trailer205
Driving and parking
Z

When overtaking, pay particular attention to theextended length of your vehicle/trailer combi-nation.
Due to the length of the vehicle/trailer combi-nation, you require additional road space whenovertaking before you can change back to theoriginal lane.
If the automatic transmission repeatedly shiftsbetween gears on uphill or downhill gradients,shift to a lower gear.
Driving in a lower gear and at a reduced speeddecreases the risk of engine damage.
If the coolant temperature increases signifi-cantly when climate control is switched on,switch climate control off.
Coolant heat can also be dissipated by openingthe windows and switching the ventilationblower and the interior temperature to the high-est level.
Decoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
GWARNING
Vehicles with level control:
The vehicle is lowered as soon as you discon-
nect the trailer cable. This could result in your
limbs or those of other people that are
between the vehicle body and tires or under-
neath the vehicle being trapped. There is a
risk of injury.
Make sure that nobody is in the immediate
vicinity of the wheel housings or under the
vehicle when you disconnect the trailer cable.
!Do not disconnect a trailer with an engagedoverrun brake. Otherwise, your vehicle couldbe damaged by the rebounding of the overrunbrake.
XApply the vehicle's parking brake manually.
XShift the transmission to position].
