– Turn the temperature control switch until the desired interior
temperature is reached.
– Turn the blower switch to any of the settings 1-4.
– Set the air distribution control to the air flow configuration desired: (towards the windsc reen), (towards the chest),
(towards the footwell) and (towards the windscreen and
footwell areas).Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Coolant system
When the air conditioning is switched on, the temperature and the air
humidity go down. This way, if the outside humidity is extreme, the air condi-
tioning prevents the misting of the windows and therefore, comfort is
improved.
If the air conditioning does not work, this may be due to the following
reasons:•
The engine is stationary.
•
The fan blower is switched off.
•
The outside temperature is below +3°C
•
The cooling system compressor has been temporarily switched off
because of an increased engine coolant temperature.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.When air recirculation mode is switched on (button ⇒page 122, fig. 90
with warning lamp) strong odours in th e outside air do not enter the vehicle
interior, for example when passing through a tunnel or in a traffic jam.
When the outside temperature is low, air recirculation mode improves
heating performance by heating air from the interior instead of cold air from
the outside.
When the outside temperature is high, air recirculation mode improves
cooling performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation should not be switched on when the
air distribution control is being adjusted to the windscreen setting
.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning syst em 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).
Note
•
When engaging reverse gear, the air recirculation is connected automati-
cally to prevent the entrance of exhaust fumes in the vehicle on travelling
backwards. The control light on the button does not light up.
•
If the temperature control is turned to the coldest setting (blue point) and
the switch is activated, the “Air recirculation” function is automatically
activated in order to cool the vehicle rapidly using less energy; its function
indicator will light.

– Turn the temperature selector to adjust the desired temperature inside the vehicle. We recommend 22°C (72°F).A comfortable interior climate is quickly reached when a temperature of
+22°C (72°F) is set in automatic mode . Therefore, we recommend you not to
change this adjustment, except as necessary to suit individual preferences or
particular circumstances. It is possible to select interior temperatures from
+18°C (64°F) up to +29°C (86°F). If a lo wer or higher temperature is selected,
LO or HI are respectively displayed on the screen. These are approximate
temperatures which may slightly vary depending on the outside conditions.

Practical tips
Te c h n i c a l D a t a
When the outside temperature is high, air recirculation mode improves
cooling performance by cooling air from the interior instead of warm air from
outside.
For safety reasons, the air recirculation
should not be switched on when the
air distribution control is being ad justed to the windscreen setting
.
WARNING
In air recirculation mode, no cold ai r 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).
Note
When engaging reverse gear, the air recirculation is connected automatically
to prevent the entrance of exhaust fumes in the vehicle on travelling back-
wards. In this case the symbol for air recirculation is not displayed.General notesThe impurity filter
The impurity 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 pollen
filter must be replaced at the specified intervals in the Maintenance Program.
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.
Caution
•
If you suspect that the air conditioning is damaged, switch it off with the
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 you to take the vehicle to a qualified
workshop.Note
•
If the humidity and temperature outside the vehicle are high, condensa-
tion can drip off the evaporator in the cooling system and so forming a puddle
underneath 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 are not impaired, and to prevent the
windows from misting over.
•
The air from the vents flows through the vehicle interior and is extracted
by slots designed for this purpose. Therefore, do not cover these slots with
items of clothing or other objects.
•
The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has been over-
heated by sun, the air in side can be cooled quicklier by opening the windows
for a short time.
•
Do not smoke while air recirculation mode is on, as smoke drawn into the
air conditioning system leaves a residue on the evaporator, producing a
permanent unpleasant odour.
•
At low outside temperatures the comp ressor switches off automatically.
The button cannot be switched on either.
•
It is advisable to connect the air conditioning at least once a month, to
lubricate the system gasket s and prevent leaks. If a decrease in the cooling
capacity is detected, an Authorised Service Centre should be consulted to
check the system.

Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 227. 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, there is a 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 belts, alternator, radiator fan, etc., and
from the high-voltage ignition syst em. You should also observe the
following points:
−Never touch the electrical wiri ng 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!
For the sake of the environment
Service fluids leaks are harmful to th e environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a qualified
workshop.

Before opening the bonnet, read and observe the warnings
⇒ page 181, “Safety instructions on wo rking in the engine compartment”.
•
Wait for the engine to cool down. Hot oil may cause burn injuries.
•
Wear eye protection to avoid injuries caused by splashes of oil.
•
When removing the oil drain plug with your fingers, keep your arm hori-
zontal to help prevent oil from running down your arm.
•
Wash your skin thoroughly if it comes into contact with engine oil.
•
Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children until it is disposed of.Caution
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
•
Because of the disposal problems, the necessary special tools and
specialist knowledge required, we recommend that you have the engine oil
and filter changed by an Authorised Service Centre.
•
Never pour oil down drains or into the ground.
•
Use a suitable container when draining the used oil. It has to be large
enough to hold all the engine oil.
CoolantCoolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive.The cooling system must be filled with a mixture of water and at least 40% of
our coolant additive G 12++ or an additive with the specification TT-VW 774 G
(recognised by its purple colour). T his mixture gives the necessary frost
protection down to -25°C and protects the alloy parts of the cooling system
against corrosion. It also prevents scal ing and raises the boiling point of the
coolant.
The concentration of coolant must always be at least 40% - even if frost
protection is not required.
If greater frost protection is required in very cold climates, the proportion of
the antifreeze additive G 12++ can be increased. However, the percentage of
coolant additives should not exceed 60%, as this would reduce the frost
protection. It would also reduce the cooling effect. A mixture with 60%
coolant additive will give frost protection to approx. -40°C.
WARNING
•
The coolant additive is toxic. Ther e is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of the
reach of children. The same applies to coolant which you have drained off.
•
The coolant additive G 12++ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold ambient temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would also
not work in this situation, there is a risk of suffering exposure!

Caution
•
Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant,
causing serious damage to the engine.
•
If additive G12++ is not available, t his can be mixed with G12+, bearing in
mind that the protection against corrosion will be reduced.
Checking the coolant level and topping up

The correct coolant level is important for fault-free func-
tioning of the engine cooling system.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 181. Opening the coolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒.
Checking coolant level
– Look into the open coolant expansion tank and read off the coolant level.
– If the level is below the “MIN” mark, top up with coolant.
Topping up coolant
–Only use new coolant.
– Do not fill above the “MAX” mark.
Closing the coolant expansion tank
–Screw the cap on again tightly.
The position of the coolant expansion reservoir is shown in the corresponding
engine compartment diagram ⇒page 238.
Ensure the coolant conforms to the required specifications. Do not use a
different type of additive if coolant ad ditive G 12++ is not available. In this
case use only water and bring the coolant concentration back up to the
correct level as soon as possible by topping up with the specified additive.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise the excess coolant will be forced
out of the cooling system when the engine is hot.
The additive G 12++ can be mixed with the G 12+ in any proportion.
