2013 MERCEDES-BENZ CLS-Class Windows

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible.
Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: ( Y page 24).Overview of climate control systems
Important safety notes
G
WARNING
Observe the settings recommended on the
following pages. The windows could
otherwise

fog up. This could prevent you from
observing the traffic conditions, thereby
causing an accident. G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its

scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at a qualified specialist workshop.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 133). i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 88).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles

of dust, and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet.
Since the replacement interval depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 124

as well as pedestrians. Fogged up or dirty windshield G
WARNING
Always remember that you must concentrate
primarily on driving the vehicle. A driver's
attention

to the road must always be his/her
primary focus when driving. For your safety
and the safety of others: stop the vehicle
before attempting to clean fogged up
windows or the windshield area in front of the
Night View Assist Plus camera.
Please remember that when your vehicle is
traveling at a speed of only 30 mph
(approximately 50 km/h) it covers a distance
of 44 ft (approximately 14 m) per second.
If the windshield in front of the camera is
fogged up or dirty on the inside or outside, the
Night View Assist Plus display is affected.
X To defrost: check the automatic air
conditioning
settings (Y page 132) and fold

General notes
G
WARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle's

doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. !
Do not park the vehicle for an extended
period

straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents
recommended and approved by Mercedes-
Benz. Washing the vehicle and cleaning the
paintwork
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the
vehicle. This could cause an accident. For
this reason, you must drive particularly
carefully after washing the vehicle until the
brakes have dried. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate

the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an
automatic car wash.
! Never clean your vehicle in a Touchless
