Switching on manual mode
–To enter manual mode, press one of the buttons ⇒ Fig. 134 1
to 5 or press the air flow control 10. The selected function is
shown on the radio or navigator display.
Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector.
The inside temperature can be set between +18 °C (64 °F) and +26 °C
(80 °F). These are approximate temperatures and the actual temperature
may be slightly higher or lower depending on the ambient conditions.
If a temperature below 18 °C (64 °F) is selected, the display switches to LO
In this setting the system runs at maximum cooling output and the tempera-
ture is not regulated.
If a temperature above 26 °C (80 °F) is selected, the display switches to HI.
In this setting the system runs at maximum heating output and the temper-
ature is not regulated.
Blower
The air flow may be adjusted freely using the control 10
. Always have the
blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. Pushing the button to the minimum -1, turns the Climatronic
off.
Air distribution
The air distribution is adjusted using the buttons
, and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning on and off
When the AC
button is on (LED lit), the air conditioning system is on.
When the AC
button is off (LED off), the air conditioning system is off. When the
AC
button is off, the air conditioning system is switched off to
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The SYNC
button controls the synchronisation of the 2 Climatronic climate
zones.
When the SYNC
button is off (LED off), the climate zone of the Climatronic is
personalised. For example: driver side temperature 22 °C and passenger
side temperature 23 °C.
When the SYNC
button is on (LED lit), the climate zone of the Climatronic is
synchronised. For example: driver side temperature 22 °C and passenger
side temperature 22 °C.
If the SYNC
button is on and the passenger side temperature is changed,
the function is automatically deactivated.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside. – Press the button
⇒ Fig. 134
2 to switch air recirculation
mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours in the ambient air from enter-
ing the vehicle interior, for example when passing through a tunnel or in a
traffic jam.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.

Vehicle maintenance and cleaning
Cleaning the radio and climate controls
To clean the radio and/or climate controls, use a soft damp cloth. For more
resistant dirt, a neutral soap solution may be used.
Seat belt cleaning
A dirty belt may not work properly.
Check all seat belts regularly and keep them clean.
Seat belt cleaning
– Pull the dirty seat belt right out and unroll it.
– Clean dirty seat belts with a gentle soap solution.
– Allow it to dry.
– Do not roll the seat belt up until it is dry.
If large stains form on the belts, it will not retract correctly into the automat-
ic belt retractor.
WARNING
● Do not use chemical cleaning agents on the seat belts, as this can im-
pair the strength of the webbing. Ensure that seat belts do not come into
contact with corrosive fluids.
● Check the condition of the seat belts at regular intervals. If you notice
that the belt webbing, fittings, retractor mechanism or buckle of any of
the belts is damaged, the belt must be replaced by a specialised work-
shop.
● Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.
CAUTION
After cleaning, allow seat belts to dry completely before rolling them up.
Otherwise, the belt retractors could become damaged.
