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 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 blower is switched off.
● The outside temperature is lower than ap-
proximately +3 °C (+37 °F).

Air conditioning
● 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.

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
A pleasant temperature is quickly reached in
automatic mode at a temperature of +22 °C
(+72 °F). Therefore, we recommend you not
to change this adjustment, except as neces-
sary to suit individual preferences or particu-
lar circumstances. It is possible to select inte-
rior temperatures from +18 °C (+64 °F) to
+26 °C (+80 °F). These are approximate tem-
peratures and the actual temperature may be
slightly higher or lower depending on out-
side ambient conditions.
Climatronic maintains a constant tempera-
ture. The temperature of the air supplied to the interior, the blower speed and the air dis-
tribution are regulated automatically. The
system also considers the sunlight radiation,
so there is no need for manual readjustment.
Therefore,
automatic mode
almo
s t always
provides the best comfort for the vehicle oc-
cupants throughout the year.
Automatic mode is switched off whenever an
adjustment is made using the buttons for the
air distribution, fan or  or the air recircula-
tion button  . The temperature will continue
to be regulated within the parameters man-
ually selected by the user. Note
There are two automatic modes:
● Automatic mode LO: this calculates the air
flow for two people.
● Automatic mode HI: this calculates the air
flow for more than two people. Manual mode

Air conditioning
In manual mode you can adjust the air tem-
perature, air flow and distribution as re-
quired.
Switching on manual mode – To enter manual mode, press one of the
buttons ››› Fig. 120 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. It is possible to select interior
temperatures from +18 °C (+64 °F) to +26 °C
(+80 °F). These are approximate tempera-
tures and the actual temperature may be
slightly higher or lower depending on the
outside ambient conditions.
If you select temperatures below +18 °C
(+64 °F), the indication: LO will appear on the
screen. 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 se-
lected, the screen will show HI. In this setting
the system runs at maximum heating output
and the temperature is not regulated. Blower
The fan may be adjusted freely using the con-
trols
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, t urn
s the Climatronic off.
Air distribution
The air distribution is adjusted using the but-
tons  ,
 and
 . It is also possible to
open and close some of the air vents sepa-
rately.
Switching the air conditioning on and off
When the A/C button is on (LED lit), the air
conditioning system is on.
When the A/C button is off (LED off), the air
conditioning system is off.
When the A/C button is off, the air condition-
ing system is switched off to save fuel. The
temperature continues to self-regulate. The
set temperature can only be reached if it is
higher than the outside temperature.
Driver and passenger temperature control
The SYNC button controls the synchronisa-
tion of the 2 Climatronic climate zones.
When the SYNC button is off (LED off), the Cli-
matronic climate zone is personalised. For
example: driver side temperature +22 °C (+72 °F) and passenger side temperature +24
℃
(+23.89 ℃
).
When the S

YNC button is on (LED lit), the Cli-
matronic climate zone is synchronised. For
example: driver side temperature +22 °C
(+72 °F) and passenger side temperature +22
℃ (+22.22 ℃
).
If

the SYNC button is on and the passenger
side temperature is changed, the function is
automatically deactivated.
Air recirculation mode –
Press the button 
››› Fig. 120 5 to
switch air recirculation mode on or off. It is
switched on if the following symbol ap-
pears in the display .
Air recirculation mode prevents strong
odours or contaminated air from the outside
from entering in the vehicle, for example
when passing through a tunnel or in a traffic
jam.
With low outside temperatures, the air recir-
culation increases the effectiveness of the
heating system by heating the air inside the
vehicle rather than the 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. »

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

Petrol operating mode cur-

manual!Have the system checked
immediately by a special-
ised workshop. LPG quality and consumption
Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe without any
problems.
LPG is a mixture of propane and butane.
A difference is drawn between winter gas and
summer gas. Winter gas has a higher propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
The vehicle's engine management adapts au-
tomatically to the LPG used. Therefore, both
types of LPG can be mixed in the tank, with-
out the need for comprehensive draining be-
fore applying a different quality LPG. LPG and safety
If you smell gas or suspect that there is a
leak in the LPG system.
››› ●
Stop the vehicle immediately.
● Switch the ignition off.
● Open all the doors to properly ventilate the
vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
LPG is a highly explosive and inflammable
substance. It may cause severe burns and
other injury.
● Due care must be taken to avoid any risk of
fire or explosion.
● When parking the vehicle in a closed area
(for example in a garage), make sure that
there is adequate ventilation, either natural
or mechanical, to neutralise the LPG in the
event of a leak. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. Note
● The LPG system must be subject to regular
inspections at a specialised workshop in ac-
cordance with the Maintenance Plan.
● The engine is always started with petrol,
even when LPG was being used when it was
switched off. For this reason the tank should
never be drained of petrol completely.
● 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.
● If while driving the system switches auto-
matically to petrol operating mode because
the LPG tank is almost empty, the next few
times the engine starts up, and depending on
the outside temperature and driving style, it
may automatically switch briefly to LPG oper-
ating mode to use up what is left in the tank.
● When the system automatically switches to
petrol operating mode because the LPG tank
is almost empty, you can revert to gas operat-
ing mode by pressing the ››› Fig. 121 GAS »

engine compartment or due to its prolonged
exposure to solar radiation. WARNING
● Never switch the engine off until the vehi-
cle is completely stationary.
● The brake servo works only when the en-
gine is running. With the engine switched off,
more strength is needed to brake. As normal
brake operation cannot be performed, risk of
accidents and serious injury may exist.
● The steering lock can be immediately
blocked once the key is removed from the ig-
nition. The vehicle cannot be steered. Risk of
accident. CAUTION
When the engine has been running under a
heavy load for a long period, heat can accu-
mulate in the engine compartment and cause
engine damage. For this reason, idle the en-
gine for approximately 2 minutes before
switching it off. Braking and parking
Braking capacity and distance The following factors impair braking capacity: New brake pads
New brake pads do not provide optimal per-
formance during the first 400 km; first they
must be “run in”. However, the reduced brak-
ing capacity may be compensated by press-
ing on the brake pedal a little harder. Avoid
overloading the brakes during run-in.
Wear
The rate of wear on the
brake pads depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. Nega-
tive factors are, for instance, city traffic, fre-
quent short trips or hard driving with abrupt
starts and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain,
or after washing the vehicle or driving
through water, the full braking effect can be
delayed by moisture (or in winter by ice) on
the discs and brake pads. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven
for some distance without using the brakes
when there is a lot of salt on the road in win-
ter. In this case, the layer of salt on the brake
discs and pads has to wear off before brak-
ing. Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if
rust has formed on the disks, it is advisable
to clean off the pads and disks by braking
firmly a few times at a moderately high speed
››› .
Faults in the brake system
If the brake pedal travel should ever increase
suddenly , this may mean that one of the two
br ak
e circuits has failed. Drive immediately
to the nearest specialised workshop and
have the fault repaired. Drive there slowly
and remember that you will have to apply
more pressure on the brake pedal and allow
for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. »

Driving
●
If the handbrake is only partially released,
this will cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehicle. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the vehicle is parked.
Always note the following points when park-
ing the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. Turn the steering wheel
slightly to engage the steering lock.
– Always take you keys with you when you
leave the vehicle ››› .Additional notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
●
If the vehicle is parked facing downhill,
turn the front wheels so that they point to-
wards the kerb .
● If the vehicle is parked facing uphill, turn
the fr ont
wheels so that they point away from
the kerb
.
● Secure the vehicle as usual by applying the
handbrake firmly and putting it in 1st gear. WARNING
● Take measures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
could ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the vehicle when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They could set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever. ●
Depending on weather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill without rolling
backward.
The system maintains brake pressure for ap-
proximately 2 seconds after the driver takes
his foot off the brake pedal to prevent the ve-
hicle from rolling backward when starting off.
During these 2 seconds, the driver has
enough time to release the clutch pedal and
accelerate without the vehicle moving and
without having to use the handbrake, making
starting off easier, more comfortable and saf-
er.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D
or R for an au-
tomatic gearbox. »
