Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 26).Overview of climate control systems

WARNING
Observe the settings recommended on the
following pages. Otherwise, th ewindows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident.
THERMATIC automatic climate control con-
trols the temperature and the humidity in the
vehicle interior and filters undesirable sub-
stances from the air.
THERMATIC automatic climate control is only
operational when the engine is running. Opti-
mum operation is only achieved when you
drive with the side windows and panorama
sliding sunroof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience 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 .Aclogged 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 Booklet
.As it
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 residual heat func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system. 122

matically. All of the vehicle's systems remain
active. If you open the door, unfasten your
seat belt or remove your foot from the brake
pedal, the engine will automatically start. The
vehicle may begi nmoving. You could suffer
serious or even fatal injury or cause an acci-
dent resulting in injury or death.
Never leave the vehicle while the ECO symbol
in the multifunction display is shown in green
or yellow .Always secure the vehicle against
rolling away before leaving it.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automatic engine switch-off The engine is only switched off if:
R
the outside temperature is within the range
that is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.
R the bonnet is closed.
R the vehicle is not being steered.
R the driver's door is closed and the seat belt
is fastened.
i The engine can be switched off automat-
ically a maximum of four times (initial stop
and three repeats) in succession .The ECO
symbol is shown in yellow in the multifunc-
tion display after the engine has been star-
ted automatically for the fourth time. The
engine can only be switched off automati-
cally again when the ECO symbol is shown
in green in the multifunction display.
i During an automatic engine switch-off, air
conditioning is reduced. If full air condition-
ing is required, the ECO start/stop function can be switched off with the ECO button
(Y

Vehicles with automatic transmission
The ECO start/stop function switches the
engine off automatically if the vehicle is
braked to a standstill and the brake remains
depressed with the transmission in position

cle is stationary, even if the engine has
been switched off automatically .Itis then
not necessary to continue applying the
brakes during the automatic stop phase.
When you depress the accelerator pedal,
the engine starts automatically and the
braking effect of the HOLD function is deac-
tivated. Depress the accelerator pedal
carefully, as the engine must be started
