ECO mode MERCEDES-BENZ C-CLASS COUPE 2015 User Guide

If you use
acategory I, forward-facing child restraint system, you shouldr emove the head restraint
from the respective seat, if possible (Y page 106). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Alwayso bserve the notes in the "Child restraint system" section (Y page 56) and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system you must replace the head restraints again immediately (Y page 105). All vehicle occupants must adjust their head restraints correctly before beginning the
journey.
Make sure that the child's feet do not touch the front seat. If necessary ,move the front seat forward
slightly.
For certain child restraint systems in weight categories II or III, this can mean that the area of use
is restricted. The maximum size setting of the child restraint system is not possible due to possible
contact with the roof.

For reason sofsafety, Mercedes-Ben zrecom-
mends that you driv ewith th elight sswitched on
even durin gthe daytime. In som ecountries,
operatio noftheheadlamps varies due to legal
requirement sand self-impose dobligations. Driving abroad
General notes If your journey takes you to countries where
vehicle
sare driven on th eopposit eside of the
road to th ecountr yinw hichthe vehicle is reg-
istered ,your headlamps must be switched to
symmetrical dipped beam as soon as possible
after crossing th eborder (only vehicle swith
Intelligen tLigh tSystem). This prevent soncom-
ing traffic from bein gdazzled. Symmetrical
light sdon otilluminate as large an area of the
edge of th ecarriageway.
Vehicles with halogen or static LED
headlamps It is no
tnecessar ytos witch your headlamps to

side of th eroad to th ecountr yinw hichthe vehi-

without switching th eheadlamps to symmetri-
cal dipped beam.
Vehicles with Intelligent Light System Before crossing th
eborder, set th eheadlamps
to symmetrical dipped beam and after returning
back to asymmetrical dipped beam via the
"Dipped-beam headlamps for driving on the
right/left "function in th eon-board computer
(Y page 247).
If th eheadlamps are converte dtosymmetrical

The hazard warning lamps switch off automati-
cally if the vehicle reaches aspeed of above
10 km/ha gain afterafull brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligen
tLight System
General notes The Intelligent Light System is
asystem that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, cornering light function, motorway mode, extended range
foglamps and off-road lights. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com- puter (Y page 247).
Active light function The active light function is
asystem that moves
the headlamps according to the steerin gmove-
mentsoft he front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Cornering light function The cornering light function improves the illu-
mination of the road over
awide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the dipped-beam headlamps are
switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer- ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/ha nd turnthe steering wheel
The cornering light function may remain lit for a
shor ttime, but is automatically switched off
after no mor ethant hree minutes. Motorwa

if you are driving at aspee dabove
11 0k m/ hand do no tmakea ny large steering
movements for at least 1000 morify ou are
driving at aspee dabov e130 km/h.
Not active: if you are driving at speeds below
80 km/h followin gactivation.
Extended range foglamps The extended range foglamps reduc
ethe glare
experienced by th edriver and improve th eillu-
minatio noftheedge of th ecarriageway.
Active: if you are driving at speeds below
70 km/h and you switch on th erear foglamp.
Not active: if, followingactivation ,you are driv-
ing at speeds abov e100 km/h or if you switch
off th erear foglamp. Adaptive Highbeam Assist Plus
General notes Wit
hA daptiv eHighbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illuminatio nisaformofi llu-
minatio nwhereby th emain beam is directed
past other road users. Other road user sare kept
out of th emain-beam. This prevent sglare .If
there is avehicle in front, for example, th emain-
beam headlamps illuminate th eareas to its right
and left ,and th evehicle in fron tisilluminate dby

The system automatically adapt sthe dipped-
beam headlam prange dependin gonthedis-
tance to th eother vehicle .Oncet he system no

Overview of climat
econtrol systems General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To preven tthe windows from mistin gup:
R switch off climate control only briefly
R activat eair-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activat ethe windscreen demistin gfunction
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improvin gthe interior
climate.
The "Cooling with air dehumidification "function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 136).
i Ventilate the vehicle for
abrief period during
warm weather, e.g. using the "Convenience
opening "feature (Y page 94). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway sobserve
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions ,e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors ,e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climate control. Overview of climat
