Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the "Windscreen demisting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with dehumidification" function is
available only when the engine is running. Opti-
mum climate control is achieved only with the
side windows and roof closed.
The residual heat function can be activated or
deactivated only with the ignition switched off
(Y page 135). The integrated filter filters out most particles of
dust and soot and completely filters out pollen.
It also reduces gaseous pollutants and odours. 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 Service Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Service Booklet.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 96). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
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.
i Hybrid vehicles:
observe the notes on cli-
mate control in the separate Owner's Manual. Control panel for THERMATIC automatic climate control

127Climate control

If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up.
Do not get back into the vehicle during the refu-
elling process, otherwise electrostatic charge
could build up again. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, fuel can enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
If you overfill the fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

(Y
page 161).
If you unlock/lock the vehicle from the outside, the fuel filler flap also unlocks/locks.

RefuellingDriving and parking

In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, e.g. in multi-storey
car parks
If DISTRONIC PLUS no longer detects a vehicle
in front, it may unexpectedly accelerate to the
speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left (in countries where
they drive on the right)
R be so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.
