Air conditioning
150Air recirculation mode ⇒page 149, fig. 125 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 ambient temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the ambient air.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air cooling system by cooling the air inside the passenger
compartment rather than the ambient air. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting
.
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.

Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector. It
is possible to select interior temper
atures from +16° C (61° F) to +29.5° C
(86° F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depending on the ambient conditions.
If a temperature below 16° C (61° F) is selected, the display switches to LO. In
this setting the system runs at maximum cooling output and the temperature
is not regulated.
If a temperature above 29.5 °C (86 °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 . 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, tu rns the Climatronic off.
Air distribution
The air distribution is adjusted using the buttons , and . Also, it is
also possible to open and close some of the air vents separately.
Switching the cooling system on and off
Pressing the button switches off the cooling system to save fuel. The
temperature continues to be regulated. The set temperature can then only be
reached if it is higher than the ambient temperature.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.– Press the button ⇒page 152, fig. 127 to switch air recir-
culation mode on or off. It is switched on if the following symbol
appears in the display

entering the vehicle interior, for example when passing through a tunnel or in
queuing traffic.
With low ambient temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the ambient air.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air cooling system by cooling the air inside the passenger
compartment rather than the ambient air.

154General notesThe pollution filter
The pollution filter (a combined particle filter and active carbon filter) serves
as a barrier against impurities in the ambient air, including dust and pollen.
For the air conditioning system to work with maximum efficiency, the pollu-
tion filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollution filter must be changed more frequently
than stated in the Service Schedule.
Caution
•
If you suspect that the air conditioner is damaged, switch off the air condi-
tioner with button to prevent further damage and have it checked by a
qualified workshop.
•
Repairs to the air conditioning system require specialist knowledge and
special tools. Therefore, we recommend that you take the vehicle to a quali-
fied workshop should problems occur.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and form a pool under-
neath the vehicle, this is completely normal and there is no need to suspect
a leak.
•
Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling is not impaired, and to prevent the
windows misting over.
•
The air from the vents flows through the passenger compartment and is
extracted by slots designed for this purpose. Do not cover these slots with
articles of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. Howe ver, if the sun has heated up the
vehicle, the air inside can be cooled more quickly by opening the windows for
a short period.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a r esidue on the evaporator, producing a
permanent unpleasant odour.

Checking and refilling levels
202
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•
Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.
•
Switch off the engine and remove the key from the ignition.
•
Apply the handbrake and move the gea r stick to neutral or selector
lever to position P.
•
Keep children away from the vehicle.
•
Never touch hot engine parts. This is a risk of burns.
•
Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.
•
Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 250. The battery could
explode.
•
Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, risk of accident!. A hydraulic
jack is insufficient for securing the vehicle and there is a risk of injury.
•
If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belt s, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!
