The fire extinguisher* is attached to the luggage compartment carpet with
Velcro.
Note
● The first-aid kit and the fire extinguisher are not part of the vehicle's
standard equipment.
● The first aid kit must comply with legal requirements.
● Observe the expiry date of the contents of the first aid kit. After it has
expired you should purchase a new one.
● The fire extinguisher must comply with legal requirements.
● Ensure that the fire extinguisher is fully functional. The fire extinguisher
should, therefore, be checked regularly. The sticker on the fire extinguisher
will inform you of the next date for checking.
● Before acquiring accessories and emergency equipment see the instruc-
tions in ⇒ page 208. 
Luggage compartment
Storing objects
All luggage must be securely stowed. Please observe the following points to ensure the vehicle handles
well at all times:
– Distribute the load as evenly as possible.
– Place heavy objects as far forward in the luggage compartment
as possible. –
Secure luggage in the luggage compartment with suitable
straps on the fastening rings.
WARNING
● Loose luggage and other loose items in the vehicle can cause serious
injuries.
● Loose objects in the luggage compartment can suddenly move and
change the way the vehicle handles.
● During sudden manoeuvres or accidents, loose objects in the passen-
ger compartment can be flung forward, injuring vehicle occupants.
● Always store objects in the luggage compartment and secure with
suitable straps. This is especially important for heavy objects.
● When you transport heavy objects, always take in account that a
change in the centre of gravity can also cause changes in vehicle han-
dling.
● Please observe information on safe driving ⇒  page 7, Safe driving.
CAUTION
Hard objects on the shelf could chafe against the wires of the heating ele-
ment in the rear window and cause damage.
Note
The ventilation slots in front of the rear side windows must not be covered
as this would prevent stale air being extracted from the vehicle. 

lower left of the button is lit.
Temperature
With the regulator 1
the heating level is determined. The required temper-
ature inside the vehicle cannot be lower than the ambient temperature.
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature. Heated rear window 

The air flow can be set at four speeds with the control 5

should always be set at the lowest speed when driving slowly.
WARNING
● For road safety all windows must be clear of ice, snow, and condensa-
tion. This is essential to ensure good visibility. Please familiarise your-
self with the correct operation of the heating and ventilation system, in-
cluding the anti-fog/defrost functions for the windscreens.
● In air recirculation mode, no cold air from the outside enters the vehi-
cle interior. The windows can quickly fog over if the heating is switched
off. Therefore, never leave the air recirculation mode switched on for a
long time (risk of accident).

Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons: ●
The engine is not running.
● The blower is switched off.
● The outside temperature is below +3°C.
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop. 
Air recirculation mode 
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.

Air recirculation mode ⇒ fig. 109 
prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

Manual mode
In manual mode you can adjust the air temperature, air flow and distribution as required.
Fig. 113 On the dash panel: 2C Climatronic controls.
Switching on manual mode
– To enter manual mode, press one of the buttons ⇒ fig. 113 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 tempera-
ture 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.
