to change up into a higher gear, move the se-
lector lever to D or lift your foot off the accel-
erator before the needle reaches the red
zone. CAUTION
To prevent possible engine malfunctions, the
rev counter needle should not reach the red
zone. The start of the red zone on the dial is
different for some engine versions. For the sake of the environment
Changing up into higher gears sooner, follow-
ing the recommended gear indications

s umption, emi

ssions and also engine noise.32

Operation
●
Due care must be taken to avoid any risk of
fire or explosion.
● When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
● The values shown in the average fuel con-
sumption and distance to empty indications
on the multifunction display (MFI) 1)
on the in-
strument panel display 2)
are approximate val-
ues only.
● Two different consumption values are given
on the MFI, depending on whether the vehi-
cle is running in gas or petrol mode.
● Please check the fuel level on the fuel level
gauge on the instrument panel ››› page 33.
● If frequent short journeys are made, espe-
cially when the outside temperature is low,
the vehicle will tend to run on petrol more of-
ten than on LPG. Therefore, the petrol tank
may empty before the LPG tank. Engine coolant temperature gauge

injury or damage to your vehicle.
● The risk of an accident increases if your ve-
hicle breaks down. Use a warning triangle to
draw the attention of other road users in or-
der to prevent danger to third parties.
● The engine compartment is a dangerous
area. Before you open the bonnet to work on
the engine or in the engine compartment,
switch the engine off and allow it to cool to
reduce the risk of burns or other injuries.
Read and observe the relevant warnings
››› page 163. Note
● The appropriate control lamp for a fault will
light up in vehicles without warning or infor-
mation messages in the display. ●
In vehicles with warning or information
messages on the screen, the appropriate con-
trol lamp for a fault will light up and a warn-
ing or information message will also appear
on the screen. Warning symbols
There are red warning symbols (priority 1)
and yellow warning symbols (priority 2).

Air recirculation mode Air recirculation mode
››› Fig. 116 4
 pre-
vents strong odours or contaminated air from the outside from entering the vehicle, for ex-
ample when passing through a tunnel or in a
traffic jam.
With low temperatures outside, the air recir-
culation increases the effectiveness of the
heating system by warming the air inside the
vehicle rather than the cold air from outside.
With high outside temperatures, the air recir-
culation increases the effectiveness 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 air re-
circulation mode is pressed, it is activated.When the recirculation mode is on, if the air
distribution towards the windscreen mode is
selected, the recirculation mode is deactiva-
ted. For safety reasons, the air recirculation
mode should not be connected. WARNING
In air recirculation mode, no cold air from the
outside enters the vehicle interior. If the air
conditioning system is switched off, the win-
dows can quickly mist over. Therefore, never
leave the air recirculation mode switched on
for a long time (risk of accident). 111Technical specifications

Operation
If the windscreen air output is on and air re-
circulation mode is pressed, this remains ac-
tive. 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 connected. WARNING
In air recirculation mode, no cold air from the
outside enters the vehicle interior. If the air
conditioning system is switched off, the win-
dows can quickly mist over. Therefore, never
leave the air recirculation mode switched on
for a long time (risk of accident). General notes
Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. 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 occu-
pants 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 fol-
lowing reasons:
● The engine is not running.
● The A/C button is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).
● 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 specialised work-
shop. CAUTION
● If you suspect that the air conditioner is
damaged, switch it off with the A/C button to
prevent further damage and have it checked
by a specialised workshop.
● Repairs to the air conditioner require spe-
cialist knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and temperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
windscreen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle interior and is extracted by slots de-
signed for this purpose. Therefore, do not
cover these slots with items of clothing or
other objects.
● The air conditioner operates most effective-
ly with the windows and the sliding/tilting
sunroof* closed. However, if the temperature
inside the vehicle is excessive because of the
sun, the air inside can be cooled faster by
opening the windows for a short time.
● Do not smoke while air recirculation mode
is on, as smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour.
● It is advisable to turn on the air condition-
ing at least once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system. 116
