air filter MERCEDES-BENZ C-Class COUPE 2017 CL205 Owner's Manual

Overview of climatecontrol systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preventt he windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improvingt he 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.
If you start the vehicle via your smartphone, the
last selected climate control setting is activated
(
Ypage 134).
iVentilate the vehicle for abrief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 88). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alwayso bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

GWARNIN G
DISTRONI CPLUSb rakes your vehicl ewithu p
to 50 %ofthe maximu mpossible deceleration.
If this braking force is insufficient, DISTRONIC
PLUS warns you visuall yand audibly.T here is
ar isk of an accident.
In such cases ,apply the brakes yourself and
try to take evasive action.
!If DISTRONIC PLUS or the HOLD function is
activated, the vehicl ebrakes automatically in
certain situations.
To prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
Rwhen towing the vehicle
Rin the car wash If you fail to adapt you
rdriving style ,DISTRONIC
PLUS can neither reduce the risk of accident nor
override the law sofphysics. DISTRONIC PLUS
cannot take into account the road ,traffic and
weather conditions. DISTRONIC PLUS is only an
aid .You are responsiblef or the distance to the
vehicl einfront, for vehicl espeed, for braking in
good time and for staying in you rlane.
Do not use DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain aconstant speede .g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating coul dcaus ethe drive wheels to lose
traction and the vehicl ecoul dthen skid
Rwhen 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 obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other rada rsources
Rthere are strong rada rreflections, for exam-
ple ,inp arking gara ges
If DISTR
ONIC PLUS no longe rdetects avehicle

accelerate the vehicl etothe stored speed.
This speedm ay:
Rbe too high if you are driving in afilter lane or

Head-up Display
General notes
The head-up display projects information from
the navigation system and the drivera ssistance
system above the dashboard into the driver's
fieldofv ision. This allows the head-up display to
collect information without you having to take
you reyeso ff of the road.
Ar equirement for the display of the contents is
that the following functions are available in the
vehiclea nd are switched on:
RCruise control
RDISTRONIC PLUS
RTrafficSign Assist
RNavigation
Important safety notes
The head-up display is only an aid and is not a
substitute for attentive driving.
The visibility of the head-up display is influenced
by the following conditions:
Rthe driver's seat position
Rthe positioning of the display image
Rthe generala mbient light
Rsunglasseswith polarizatio nfilters
Rwet roads
Rblocking of sunlight by objects on the display
cover
In the event of extreme sunlight, sections of the
display may fade .This can be reversedb y
switching the head-up display off and on again.
iVehicles with the head-up display are equip-
ped with aspecial windshield. Shoul drepairs
be necessary, have the windshiel dreplaced at
aq ualified specialist workshop.

Information about Service
Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at aqualifieds pecialist work-
shop.
Have service work carried out as describedi n
the Maintenance Booklet. This may otherwise
leadtoi ncreased weara nd damage to the
major assemblies or the vehicle.
Aq ualifieds pecialist workshop, e.g. an author-
ized Mercedes-Benz Center, wil lreset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special servic erequirements
The specifiedm aintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating conditions or
increased load on the vehicle,m aintenance
work must be carried out more frequently, for
example:
Rregular city driving with frequent intermediate
stops
Rif the vehicle is primarily used to travel short
distances
Ruse in mountainou sterrain or on poor road
surfaces
Rif the engine is often left idling for long periods
Under these or similar conditions, have, for
example ,the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be obtained at aqualifieds pecialist workshop, e.g.
an authorized Mercedes-Benz Center.

Importan tsafety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool dow nbefore yo uadd anti-
freeze .Make sur ethat antifreeze is not spilled
next to the filler neck. Thoroughly clea nthe
antifreeze from components before starting
the engine.
!Only ad dcoolant that has bee npremixed
with the desire dantifreeze protection. You
coul dotherwise damag ethe engine.

vice products whe nhandling coolant
(
Ypage 344).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection dow nto
-35 ‡(-37† ), the boiling point of the coolant
during operation is approximatel y266 ‡
