The memory function can be used at any time,
e.g. even when the key is not in the ignition lock. With the memory function, you can store up to
three different settings, e.g. for three different
people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R driver's side: steering wheel position
R driver's side: position of the exterior mirrors
on the driver's and front-passenger sides X
Adjust the seat (Y page 104).
X On the driver's side, adjust the steering wheel
(Y page 114) and the exterior mirrors
(Y page 116).

control
Optimum use of the automatic climate
control The following contains notes and recommenda-
tions on how best to use THERMATIC automatic climate control or THERMOTRONIC.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Vehicles with THERMOTRONIC:in auto-
matic mode, you can also use the ñbutton
to set a climate mode (FOCUS/MEDIUM/
DIFFUSE). The MEDIUM level is recommen-
ded.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use air-recirculation mode only briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist up as no fresh air is drawn into the vehicle in
air-recirculation mode. R
Vehicles with THERMOTRONIC:use the
ZONE function to adopt the temperature set-
tings on the driver's side for the front-
passenger side and the rear compartment as well. The indicator lamp above the ábut-
ton goes out.
R Vehicles with THERMOTRONIC:use the
"residual heat" function if you want to heat or
ventilate the vehicle interior when the ignitionis switched off. The residual heat function can
be activated or deactivated only with the igni- tion switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 153).134
