lights MERCEDES-BENZ C-CLASS COUPE 2015 Workshop Manual

The ECO display consist
softhree sections, with
an inner and outer area. The section scorre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration ,especially at higher
speeds.
R the outer area empties and the
inner area is grey: sporty acceler-
ation. ;
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking. =
Constant
(continuous evaluation
over the entir ejourney):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and decelera-
tion.
R the outer area empties and the
inner area is grey: fluctuations in
speed. The three inner areas display the current driving
style and light up green as aresult of aparticu-
larly economical driving style. Dependin gonthe
driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as aresult of eco-
nomical driving. Ahigher level indicates amore
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under
Bonus fr. start Bonus fr. start does not
indicate afixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factor sare not included in the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve ahigher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehicles
with DYNAMIC SELECT switch)
On long journeys at aconstant speed, e.g. on the
motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of ajourney. During
ap rolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 238).

WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect ,the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients Change into
alower gear in good time on long
and steep downhill gradients. Take particular Driving tips

Tip sfor driving with DISTRONIC PLUS General notes
Pay particular attention in the followin gtraffic
situations:
R Cornering, enterin gand exiting abend: the
ability of DISTRONIC PLUS to detec tvehicles
when cornering is limited. Your vehicle may
brak eunexpectedly or late.
R Driving on adifferen tline: DISTRONIC PLUS
may not detec tvehicles which are not driving
in the middle of their lane. The distance to the
vehicle in fron twill be too short.
R Other vehicles changing lane: DISTRONIC
PLUS has not detected the vehicle cuttin gin
yet. The distance to this vehicle will be too
short.
R Narro wvehicles: DISTRONIC PLUS has not
yet detected the vehicle in fron tonthe edge
of the carriageway because of its narrow
width. The distance to the vehicle in fron twill
be too short.
R Obstacles and stationar yvehicles:
DISTRONIC PLUS does not brak efor obsta-
cles or stationar yvehicles. If, for example, the
detected vehicle turn sacorner and reveals an
obstacle or stationar yvehicle, DISTRONIC
PLUS will not brak efor these.
R Crossin gvehicles: DISTRONIC PLUS may mis-
takenly detec tvehicles that are crossin gyour
lane. Activatin gDISTRONIC PLUS at traffic
light swith crossin gtraffic ,for example, could
cause your vehicle to pull away unintention-
ally.

General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems
