2016 MERCEDES-BENZ GLC COUPE sensor

DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front. Vehicles are detected with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and prevents the brakes from overheat- ing and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of
collision with the vehicle in front, you will be
warned visually and audibly. Without your inter- vention, DISTRONIC PLUS cannot prevent a col-
lision. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately to increase the distance to the vehicle in front,
or take evasive action, provided it is safe to do
so.
DISTRONIC PLUS operates in the speed range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions. In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes your vehicle with up to 50 %of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
DISTRONIC PLUS can neither reduce the risk of
an accident if you fail to adapt your driving style
nor override the laws of physics. DISTRONIC
PLUS cannot take into account road, weather or traffic conditions. DISTRONIC PLUS is only an
aid. You are responsible for maintaining a safe
distance, for vehicle speed, for braking in good
time and for staying in lane.
Do not use DISTRONIC PLUS:
R in traffic conditions that do not allow you to
maintain a constant speed, e.g. in heavy traf-
fic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. 178
Driving systemsDriving and parking

In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, e.g. in multi-storey
car parks
If DISTRONIC PLUS no longer detects a vehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left (in countries where
they drive on the right)
R be so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.

4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
If a drive wheel spins due to insufficient grip:
R When pulling away, only depress the acceler-
ator pedal as far as is necessary.
R accelerate less when driving.
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tyres (M+S tyres), with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasound. It monitors the area around your
vehicle using six sensors in the front bumper
and six sensors in the rear bumper.
PARKTRONIC visually and audibly indicates the
distance between your vehicle and an object.
PARKTRONIC is only an aid. It is not a substitute for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that
there are no persons, animals or objects in
range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic car
wash, a lorry's compressed-air brakes or a
pneumatic drill, could cause PARKTRONIC to
malfunction.
PARKTRONIC may not function correctly on
uneven terrain. !
Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC measures the minimum detection range to an obstacle
from the bumper, not the ball coupling.
PARKTRONIC is activated automatically when
you: R switch on the ignition
R shift the transmission to position D,Ror N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC is deactivated for the rear area
when you establish the electrical connection
between your vehicle and a trailer.
Range of the sensors PARKTRONIC does not take into account obsta-
cles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods

Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 210) and Lane Keeping
Assist (Y page 211).
Blind Spot Assist General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning lamp lights up on the exterior
mirror and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free of dirt, ice and slush. The sen- sors must not be covered, e.g. by cycle racks oroverhanging loads. Following a severe impact or in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali- fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext to =and behind :your vehicle, as
shown in the picture.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time 210

When Adaptive Adaptive is selected, no warning vibra-
tion occurs if:
R you have switched on the turn signal. In this

engages
R you accelerate hard, e.g. kickdown
R you brake hard
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly
R you cut the corner on a sharp bend
To ensure that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system detects certain conditions
and warns you accordingly.
The warning vibration occurs earlier in the fol-
lowing situations:
R you approach the outer lane marking on a
bend
R the road has very wide lanes, e.g. a motorway
R the system detects solid lane markings
The warning vibration occurs later in the follow- ing situations:
R the road has narrow lanes
R you cut the corner on a bend Driving Assistance Plus package
General notes The Driving Assistance PLUS package consists
of DISTRONIC PLUS (Y page 178), Active Blind
Spot Assist (Y page 213) and Active Lane Keep-
ing Assist (Y page 216).
Active Blind Spot Assist General notes
Using two lateral, rear-facing radar sensors,
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not visible to
the driver. A warning lamp lights up on the exte- rior mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning. If a risk of side impact is detec- ted, a course-corrective brake application may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direction
of travel and to the side before making a course-correcting brake application. For this, Active
Blind Spot Assist uses the forward-facing radar
sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated in the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The rear sen-
sors must not be covered, e.g. by bicycle racks
or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist might otherwise no longer function prop-
erly. Driving systems

WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. At a distance of approximately 0.5 m
;from
the vehicle, Active Blind Spot Assist monitors
the area up to 3.0 m next to =and behind :

such as lorries, for a prolonged time
Warning lamp :
Warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If a vehicle is detected within the blind spot
monitoring range at speeds of more than
approximately 30 km/h, warning lamp :on
the corresponding side lights up red. This warn-
ing lamp always lights up when a vehicle enters the blind spot monitoring range from behind or
from the side. When you overtake a vehicle, the
warning occurs only if the difference in speed is less than 12 km/h.
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings. 214
