Air recirculation mode
⇒page 146, fig. 110 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 temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the cold air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is select ed, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be
connected.
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).

or press the air flow control . 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.
The compartment temperature can be set between +18°C (64°F) and +26°C
(80°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 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 26°C (80°F) is selected, the display switches to
HI In
this setting the system runs at maximum heating output and the temperature
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, turns the Climatronic off.

Heating, Ventilation and Air conditioning
152When the button is off (LED off), the heating, ventilation and air condi-
tioning system is off.
When the button is off, the heat ing, ventilation and air conditioning
system is switched off to save fuel. The temperature continues to self-regu-
late. The set temperature can then only be reached if it is higher than the
ambient temperature.
Driver and passenger temperature control
The button controls the synchronisation of the 2 Climatronic climate
zones.
When the button is on (LED lit), the climate zone of the Climatronic is
personalised, for example: Driver side temperature 22°C and passenger side
temperature 23°C.
When the button is off (LED off), the climate zone of the Climatronic is
synchronised, for example: Driver side temperature 22°C and passenger side
temperature 22°C.
If the button is off and the passenger side temperature is changed, the
function is automatically activated.Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells
from coming from the outside.– Press the button ⇒page 151, fig. 114 to switch air recir-
culation mode on or off. It is switched on if the following symbol
appears in the display

.
Air recirculation mode prevents stro ng odours in the ambient air from
entering the vehicle interior, for example when passing through a tunnel or in
a traffic jam. With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than th
e air from outside.
With high ambient temperatures, the ai r recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. 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 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).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 wo rk with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
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 occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning sy
stem cannot be switched on this may be caused by
the following reasons:
•
The engine is not running.
•
The button is disconnected.
•
The outside temperature is below +3°C.
•
The air conditioning syst em 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.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 passenger compartment and is
extracted by slots designed for this pu rpose. 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.
•
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.

Trailer towing
190If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle and
including the maximum resting weight.
Elevation values for securing the towing bracket:
65 mm (minimum)
350 mm to 420 mm (fully laden vehicle)
357 mm
569 mm
875 mm
1,040 mm
Fitting a towing bracket•
Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.
•
Submit to the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securin g bolts must be tightened using a
torque wrench, and an electrical socket must be connected to the vehicle's
electrical system. The above-mentione d require specialized knowledge and
tools.
•
Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.
WARNING
Towing brackets should be fitted by specialists.
•
If the towing bracket is incorrectly installed, there is serious danger of
accident.
•
For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•
If the electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.Note
For the sports model (FR, Cupra...), fi tting of a trailer bracket is not recom-
mended due to the design of the bumpers.

Checking and refilling levels
206
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 254. 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 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!
