2015 MERCEDES-BENZ C-CLASS COUPE cruise control

Stopping
G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is amalfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by avehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment,t he battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by avehicle occupant.
There is arisk 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 190).
If DISTRONIC PLUS detectst hat the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i After
ashort period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to astandstill at
as ufficient distance behind the vehicle in
front.T he 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 Pif:
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 The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R as ystem fault occurs
R the power supply is insufficient
If af ault occurs, the transmission may also shift
into position Pautomatically.
Setting aspeed X
Press the cruise control lever up :for a
higher speed or down Afor alower speed.
X Keep the cruise control lever pressed 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 in
1km/h incre-
ments: briefly press the cruise control lever
up : or down Ato the pressure point.
The last stored speed increases or decreases
in 1k m/h increments.
X To adjust the set speed in 10 km/h incre-
ments: briefly press 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 to the last
speed stored after you have finished overtak-
ing.
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. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front,d ependent on vehicle speed. You can see
this distance in the multifunction display
(Y page 189).
i Make sure that you maintain the minimum
distance to the vehicle in front as required by law. Adjust the distance to the vehicle in front
if necessary. 188
Driving systemsDriving and parking

Only release the ball coupling if the pivoting
range is unobstructed. Alwaysm ake sure that
the ball coupling engages when folding in.
When reversing the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
Couple and uncouple the trailer carefully.Ify ou
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to when driving without atrailer.
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 alarger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, always adjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissibles peed for
your vehicle/trailer combination. Notes on towing
atrailer
General notes Trailer towing is not permissibleont
he following
models:
R Mercedes AMG C63
R Mercedes AMG C63S
When towing atrailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 356).
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 378). Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 74).
The maximum permissibles peed 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 legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 378). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed amaximum speed of 100 km/h for rea-
sons concerning the operating permit. This also applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing atrailer, your vehicle's handling
characteristics will be different in comparison to
when driving without atrailer and it will con-
sume more fuel.
Change into alower gear in good time on long
and steep downhill gradients.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain agreater distance to the vehicle in
front than when driving without atrailer.
R Avoid braking abruptly.Ifp ossible,brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The valuesg iven for gradient-climbing capa-
bilities from astandstill refer to sea level.
