2015 MERCEDES-BENZ C-CLASS COUPE warning

In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
R accelerate or brake unexpectedly
There is arisk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes yourv ehicle with up
to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with avisuala nd
acoustic warning. There is arisk 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- icallyinc ertain 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 ac ar wash
If you fail to adapt yourd riving style, DISTRONIC
PLUS can neither reduce the risk of an accident
nor override the lawsofp hysics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid.Y ou are responsible for the
distance to the vehicle in front, for vehicle
speed,f or braking in good time, and for staying
in lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed,e .g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheelstol ose
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
adifferent line.
In particular, the detection of obstacle scan be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radars ources
R the possibility of strong radarr eflections, for
example ,inmulti-storey car parks
If DISTRONIC PLUS no longer detects avehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for afilter lane or aslip road
R be so high in the right lane that you pass vehi-
cles driving on the left (left-hand drive coun-
tries)
R be so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is achange of drivers, advise the new
driver of the speed stored.

X Remove yourf oot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
i If you do not fullyr
elease the accelerator
pedal, the DISTRONIC
DISTRONIC PLUS PLUSsuspended
suspended mes-
sage appears in the multifunction display. The set distance to aslower-moving vehicle in front willt
hen not be maintained .The position
of the accelerator pedalw illd etermine the
speed.
You can also activate DISTRONIC PLUS when
stationary .The lowest speed that can be set is
30 km/h.
X Briefly pullt he cruise control lever towards
you ?,up:or down A.
DISTRONIC PLUS is activated.
Activating at the current speed/last
stored speed G
WARNING
If you call up astored speed and this is dif-
ferent from the current speed,t he vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly .There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed.Ify ou do
not know whatt he stored speed is, store the
desire dspeed again.
X Briefly pullt he cruise control lever towards
you ?.
X Remove yourf oot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle cruise speed to the
previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving
X If you want to pull away with DISTRONIC
PLUS: remove yourf oot from the brake pedal.
X Briefly pullt he cruise control lever towards
you ?.
or X Accelerate briefly.
Yourv ehicle pulls awaya nd adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, yourv ehicle accelerates to
the set speed.
The vehicle can also pulla wayw hen it is facing
an unidentified obstacle or is driving on adiffer-
ent line from another vehicle .The vehicle then
brakes automatically. 186

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

RACE START enables optimum acceleration
from astandin gstart .For this, asuitably high-
grip road surface is required, along with the
tyres and vehicle being in good condition. G
WARNING
If you use RACE START, individual tyres may
get into aspin and the vehicle could skid.
Dependin gonthe selected ESP ®
mode, there
is an increased risk of skidding and having an accident .Make sure that no persons ,animals
or obstacles are within range of the vehicle.
i Observe the safety notes on driving safety
systems (Y page 66).
Be sure to read the safety notes and informa-
tion on ESP ®
(Y page 71).
