– Turn the temperature control switch until the desired interior
temperature is obtained.
– Turn the blower switch to one 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 foot rest) and (towards the windscreen and
foot rest 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 cooling 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 outside
air humidity is high.
If the cooling system cannot be switched on this may be due to the following
reasons:•
the engine is not running.
•
The blower is switched off.
•
The outside temperature is lower than +5°C.
•
the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•
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 entering the vehicle.When air recirculation mode is switched on (button ⇒page 120, fig. 91
with warning lamp) strong odours in th e outside air do not enter the vehicle
interior, for example when passing th rough a tunnel or in queuing traffic.
When the outside temperature is low, using air recirculation mode provides
more effective heating by heating air from the vehicle interior instead of cold
air from outside.
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air from the vehicle interior instead of warm
air from outside.
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.
Note
•
When reverse gear is engaged the air recirculation connects automatically
to prevent the entrance of exhaust fumes in the vehicle on travelling back-
wards. 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 passenger compartment rapidly using a
minimum of energy and the fu nction indicator will light.

Heating, Ventilation and Air conditioning
124Climatronic maintains a constant temperature level fully automatically. The
temperature of the air supplied to the interior, the blower speed and the air
distribution are regulated automatically. The system also allows for the effect
of strong sunlight, so there is no need for manual adjustment. Therefore,
automatic mode provides the best comfort for the vehicle occupants in virtu-
ally all conditions throughout the year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribution, blower or . The temperature continues
to be regulated.Manual mode
In manual mode you can adjust the air temperature, flow, and
distribution yourself.Switching on manual mode
– Press one of the buttons ⇒page 122, fig. 92 to , or turn
the blower control . The display is switched off .Temperature
It is possible to select interior te mperatures from +18°C (64°F) to +29°C
(86°F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depen ding on the outside 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 temperature
is not regulated.
If a temperature above 29°C (86°F) is selected the display indicates HI . In this
setting the system runs at maximum heating output and the temperature is
not controlled. Blower
The blower can be infinitely adjusted
with the blower control . Always have
the blower running at a low setting to ensure a constant flow of fresh air into
the vehicle. If the blower is switched off (no level displayed ) and the
control is turned further to the left, th e Climatronic is switched off. Then OFF
is displayed on the screen.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air outlets separately.
Switching the air conditioning system on and off
Pressing the button switches off the air 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 outside temperature.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.– Press the button to switch air recirculation mode on or off. This is ON if the symbol

⇒ page 122, fig. 92 is displayed
on the screen.
Air recirculation mode pr events strong odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
queuing traffic.

Tips and Maintenance
Te c h n i c a l D a t a
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air fr
om the vehicle interior instead of warm
air from outside.
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 of f, 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.
Note
When reverse gear is engaged the air recirculation connects automatically to
prevent the entrance of exhaust fumes in the vehicle on travelling backwards.
In this case the symbol for air recirculation is not displayed.General notesThe pollen filter
The pollution filter (a combined particulate 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 interv als specified in the Maintenance Program.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, 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 off the air
conditioning 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. However, 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 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.

Checking and refilling levels
176this reason we recommend that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 167. The engine compartment of any motor vehicle is a
hazardous area ⇒.
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. There 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 222. 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 th e 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 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.WARNING (continued)

182Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule.We recommend that you have the engine oil changed by an Authorised
Service Centre.
The oil change intervals are shown in the Maintenance Programme.
WARNING
Only change the oil yourself if you have the specialist knowledge required!•
Before opening the bonnet, read and observe the warnings
⇒ page 175, “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 additi ve with the specification TT-VW 774 F
(it is dyed purple). This mixture gives the necessary frost protection down to
-25
°C and protects the alloy parts of the cooling system against corrosion. It
also prevents scaling 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 br eakdown. 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.
•
The coolant additive G 12+ (purple) can be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11.
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 175.
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.

Checking and refilling levels
184
– If the level is underneath 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 232.
Make sure that the coolant meets the required specifications ⇒page 182.
Do not use a different type of additive if coolant additive G 12+, is not avail-
able. In this case use only water and bring the coolant concentration back up
to the correct level as soon as possible by putting in the specified additive
⇒ page 182.
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 coolant additive G 12+ (dyed purple) may be mixed with G 12 (dyed red)
and also with G 11.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartment, always observe the safety
warnings ⇒ page 175
•
When the engine is warm or hot, the cooling system is pressurised! Do
not unscrew the cap on the expansion tank when the engine is hot. This is
a burn injury risk.Caution
•
When mixed with other additives the colour of G 12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to do
so will result in engine damage!
•
If a lot of coolant has been lost, wait for the engine to cool down before
putting in cold coolant. This avoi ds damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.WARNING (continued)
