2016 MERCEDES-BENZ GLC COUPE cruise control

Vehicles with COMAND Online multimedia
system: when you change lanes, DISTRONIC
PLUS monitors the right lane in the case of left-
side traffic or the left lane in the case of right-
side traffic.
Vehicles with Audio 20 multimedia system:
when you change lanes, DISTRONIC PLUS mon- itors the left lane on left-hand-drive vehicles or
the right lane on right-hand-drive vehicles.
Road and traffic conditions The following function is available only in vehi-
cles with the Driving Assistance Plus package.
The function is not operational in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations.
This is the case if, while you are following a vehi-
cle, DISTRONIC PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
R approach a tollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler-
ate. This is based on the current map data in the navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
of more than 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles in
the adjacent lane to the left.
Prevention of overtaking on the right applies to
countries where traffic drives on the right. In
countries where traffic drives on the left, over-
taking on the left is prevented accordingly. Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating DISTRONIC PLUS (Y page 183).
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake to a standstill.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a short period, the vehicle is secured by
the electric parking brake, thus relieving 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. The
specified minimum distance is set using the
control on the cruise control lever.
When DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position Pin
the following situations:
R the driver's seat belt is not fastened and the
driver's door is open
R The engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function Driving systems
181Driving and parking Z

The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a fault occurs, the transmission may also shift
to position Pautomatically.
Setting a speed X
Push the cruise control lever up :for a
higher speed or down Afor a lower speed.
X Push and hold the cruise control lever until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored. DISTRONIC PLUS is
activated and adjusts the vehicle's speed to
the new speed stored.
X To adjust the set speed in1 km/hincre-
ments:
briefly push the cruise control lever
up : or down Ato the pressure point.
The last stored speed increases or decreases in 1 km/h increments.
X To adjust the set speed in10 km/hincre-
ments:
briefly push the cruise control lever
up : or down Abeyond the pressure point.
The last stored speed increases or decreases
in 10 km/h increments.
i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed back to the
last speed stored after you have finished over-
taking.
Setting the specified minimum distance You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. This time span
determines the distance that DISTRONIC PLUS
is to maintain from the vehicle in front, depend- ing on the road speed. You can see this distance
on the multifunction display (Y page 183).
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. X
To increase: turn control;in direction =.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the vehicle in front.
X To decrease: turn control;in direction :.
DISTRONIC PLUS then maintains a shorter
distance between your vehicle and the vehicle
in front.
DISTRONIC PLUS displays on the instru- ment cluster Displays in the speedometer
If DISTRONIC PLUS detects a vehicle in front,
the segments between the speed of the vehicle
in front :and stored speed ;light up.
Vehicles with the Driving Assistance Plus
package: the segments likewise light up if a
vehicle in front is detected in the fast lane.
For design reasons, the speed displayed in the
speedometer may differ slightly from the speed
set for DISTRONIC PLUS. 182

The vehicle/trailer combination could become
unstable.
The vehicle/trailer combination could also
become unstable if the noseweight used is lower
than the minimum permissible noseweight.
To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R use a noseweight as close as possible to the
maximum noseweight
R do not exceed the maximum permissible
noseweight
R do not use a noseweight lower than the min-
imum noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find permissible trailer loads under
"Technical data" (Y page 380).
When reversing the towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds R
demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a maxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 359).
You will find permissible trailer loads under
"Technical data" (Y page 380).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 76).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted 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 increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 381). In the event of increased
rear axle load, the car/trailer combination may
not exceed a maximum speed of 100 km/ hfor
reasons concerning the operating permit. This
also applies in countries in which the maximum
permissible speed for car/trailer combinations
is greater than 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift to a lower gear in good time on long and
steep downhill gradients.
This also applies in the case of:
R activated DISTRONIC PLUS
R activated cruise control Towing a trailer

Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
