Automatic air recirculation mode
o
Fresh air enters the vehicle interior in position o. If the system detects a high
concentration of hazardous substances in the ambient air, air recirculation
mode is switched on automatically. When the level of impurities drops to
within a normal range, recirculation mode is switched off.
The system is unable to detect unpleasant smells.
Air recirculation mode is not automatically switched on in the following cases
of outside temperatures and conditions:
xThe cooling system is switched on (the button is lit up) and the
outside temperature is below +3 °C (+38 °F).
xThe cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
xThe cooling system is switched on, the outside temperature is below +15
°C (+59 °F) and the windscreen wipers are switched on.
Switching the automatic air recirculation mode on and off
Switching on: press the button until the light under the symbol
o
comes on.
Switching off: press the button until no button remains lit.
Switching the automatic air recirculation mode off temporarily
xPress the button once to temporarily switch to manual air recircula-
tion mode in the event of unpleasant smells from outside. The control light
under the symbol
 comes on.
xAfter more than two seconds, press the button again to restart
automatic air recirculation. The control light under the symbol o comes on.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
xNever use recirculation mode for long periods as it does not refresh the
air inside the vehicle.
xIf the cooling mode is switched off and air recirculation mode switched
on, the windows can mist over very quickly, considerably limiting visibility.
xSwitch air recirculation mode off when it is not required.
Caution
Do not smoke when air recirculation is switched on in vehicles with a climate
control system. The smoke taken in could lie on the cooling system vaporiser
and on the activated charcoal cartridge of the dust and pollen filter, leading
to a permanently unpleasant smell.
Note
Air recirculation mode switches on to prevent exhaust gas from entering the
vehicle interior when it is in reverse and while the automatic windscreen
wash and wipe is working.

Driving and the environment253
Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Some equipment, when connected, increase fuel consumption considerably,
for example:
xAir conditioning cooling system: If the air conditioning system is required
to cool to significantly lower temperatures than the true outside temperature,
it will require a large quantity of energy from the engine. Therefore, we recom-
mend that the selected temperature for the vehicle is not too different to the
outside temperature. It is a good idea to open all the windows of the car
before starting your journey, and to drive a short distance with all the
windows open to allow the vehicle to cool down slightly. Only then should
you close all the windows and switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driving with the windows open
increases fuel consumption.
xSwitch off the seat heating when the seats have warmed up.
xSwitch off the heated rear window and the windscreen heating when the
windows have demisted and are free of ice.
xDo not leave the independent heating switched on when the vehicle is
moving Ÿpage 187.
Other factors which increase fuel consumption (examples):
xFault in engine management.
xDriving on hills.
xTrailer towing.
Saving fuel while driving
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%.
A vehicle uses most fuel when accelerating. By anticipating the traffic situa-
tion ahead, you will brake and therefore accelerate less. Wherever possible,
let the car roll slowly to a stop, for instance when you can see that the next
traffic lights are red.
Avoid short journeys
Fuel consumption is much higher when the engine is cold, immediately after
it has been started. It takes a few kilometres of driving for the engine to warm
up and to normalise consumption.
The engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions. The
ambient temperature has a decisive influence.
fig. 162 shows the difference in consumption for the same journey at +20 °C
(+68 °F) and at -10 °C (+14 °F).

tion in litres per 100 km at

Trailer towing 260
Driving with a trailer
Technical requirements
If the car is supplied with a factory-fitted tow hitch it will already have the
necessary technical modifications and meet the statutory requirements for
towing a trailer.
Only use an approved trailer hitch for the gross trailer weight rating. The tow
hitch must be suitable for both the vehicle and trailer and must be securely
fitted to the vehicle chassis. Only use a tow hitch with a removable ball joint.
Always check and take into account the tow hitch manufacturer's instruc-
tions. Never fit a trailer tow hitch “that distributes the load” or “balances the
load”.
Bumper mounted tow hitch
Never fit a tow hitch or its attachments to the bumper. A tow hitch should
never interfere with the bumper performance. Do not modify the exhaust
system and brake system. Regularly check the tow hitch to ensure it is firmly
fitted.
Engine cooling system
Driving with a trailer increases the load on the engine and cooling system.
The cooling system should always have sufficient coolant and to be able to
cope with the vehicle and trailer.
Electric trailer brake
If the trailer has its own braking system, please note the relevant legal
requirements. The trailer braking system should never be connected to the
vehicle braking system.
Trailer cable
Always use a cable between the vehicle and the trailer Ÿpage 262.Trailer rear lights
The rear lights of a trailer must fulfil the corresponding standards
Ÿpage 262.
Never connect the trailer's rear lights directly to the vehicle electric system. In
case of any doubt about the electrical connection of the trailer, ask a
specialist workshop. SEAT recommends visiting a qualified workshop.
Wing mirrors
When the field of vision behind the trailer cannot be seen using the standard
wing mirrors of the towing vehicle, additional wing mirrors are required
according to the legal requirements of each country. The wing mirrors must
be fitted before driving and must provide a sufficient field of vision behind.
Trailer electricity consumption
Never exceed the specifications:
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the vehicle causing an accident with serious consequences.
Caution
xIf the rear lights of the trailer are not correctly connected, the vehicle elec-
tronics may be damaged.

xThe maximum drawbar load is used.
xThe trailer must have a fixed drawbar.
xTrailers with brakes must be equipped with a mechanical inertia brake.
WARNING
Do not let the extra safety afforded by the stabilisation system tempt you
into taking any risks when driving.
xAdjust your speed and driving style to visibility, road, traffic and
weather conditions.
xIf the road surface is slippery, take care when accelerating.
xWhen a system is operating, lift your foot off the accelerator.
WARNING
It is possible that the combination stabilisation system does not correctly
recognised all driving situations.
xIt is possible that the stabilisation system does not detect snaking of a
light trailer and thus does not intervene.
xWhen driving on slippery ground, the trailer could jack-knife despite
the stabilisation system.
xTrailers with a high centre of gravity may even tip over before they start
to rock sideways.
xIf a trailer is not used at the trailer socket is connected (for example,
installation of a bicycle carrier with lights), repeated automatic braking
may occur in extreme driving conditions.
Retrofitting a tow hitch
Fig. 164 Measurements and attachments to retrofit a tow hitch.
SEAT recommends visiting a specialist workshop to retrofit a tow hitch. For
example, it may be necessary to adjust the cooling system or to include
thermal plates. SEAT recommends visiting a qualified workshop.
In any case, the separation distances must be observed when fitting a tow
hitch. The distance between the centre of the tow hitch ball and the road
surface Ÿfig. 164 must never be lower than that indicated. This also
applies when the vehicle is fully laden, including maximum drawbar load.

xNever mount, fasten or fit objects such as drink holders or telephone
cradles over the covers of the airbag modules or within their radius of
action.
xObjects placed over the airbag covers, or within their radius of action,
could lead to serious injury or loss of life if the airbags are triggered.
Fluids and consumables
All vehicle fluids and consumables, such as notched belts, tyres, coolant
fluids, engine oils, spark plugs and batteries are continually being devel-
oped. Therefore all fluids and consumables should be changed at a qualified
workshop. Qualified workshops are permanently informed of any modifica-
tions.
WARNING
The incorrect use or handling of fluids or consumables may result in acci-
dent, serious injury, burns or intoxication.
xTherefore, fluids must always be stored closed in their original
container.
xNever store fluids in empty food containers or bottles as other people
may accidentally drink the fluid.
xKeep all fluids and consumables out of reach of children.
xRead and observe the information and warnings given on the fluid
containers.
xOnly work in the open air or in well-ventilated zones, when using prod-
ucts which give off harmful vapours.
xNever use fuel, turpentine, engine oil, acetone or any other volatile
liquid in the maintenance of the vehicle. These are toxic and highly flam-
mable. They could lead to fire or explosions!
Caution
xOnly use appropriate fluids. Never mix the fluids. Failure to observe this
point will result in serious malfunctions and engine damage!
xAccessories and other components mounted in front of the air inlet
reduce the cooling effect of the coolant. If the engine is running under great
strain in high outside temperatures, it could overheat.
For the sake of the environment
Leaking fluids could pollute the environment. Collect any spilt fluids in suit-
able containers and dispose of in accordance with legislation and with
respect for the environment.
Repairs and technical changes
When performing repairs and technical modifications, SEAT's directives
must be observed! Ÿ
Unauthorised modifications to the electronic components or software in the
vehicle may cause malfunctions. Due to the way the electronic components
are linked together in networks, other indirect systems may be affected by the
faults. This may significantly affect the vehicle's performance, increase
component wear and could mean that the vehicle registration documents are
no longer valid.
Your Technical Service cannot be held liable for any damage caused by tech-
nical modifications or repairs performed incorrectly.

xWhen 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. Other-
wise, coolant may spray out under pressure causing burns and serious
injury.
Carefully and slowly unscrew the cap anticlockwise, gently pressing
down on it.
Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
xWhen refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.
WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
xNever cause short circuits in the electrical system. The battery could
explode.
xTo minimise the risk of electric shock and serious consequences while
the engine is running or starting the engine, note the following:
Never touch the electrical wiring of the ignition system.
Never touch electric cables or the gas discharge lamps.
WARNING
In the engine compartment, there are rotating parts that could cause
serious injury.
xNever place your hands on or near the radiator fan. Touching the rotor
blades could seriously harm you. The ventilator works according to the
engine temperature and could start suddenly even when the ignition is
turned off and the key is removed.
xIf 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 as well as
from the high-voltage ignition system. Always work with the utmost
caution.
Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the
engine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even with the electronic parking
brake activated.
xAlways make sure you have not left any objects, such as cloths or tools,
in the engine compartment. If any object is left in the engine compartment,
this could cause malfunctions, engine faults and even a fire.
WARNING
Refill liquids and certain materials can catch fire easily in the engine
compartment, causing a fire and serious injury!
xNever smoke.
xNever work close to places exposed to flames or sparks.
xNever pour service fluids over the engine. These fluid may ignite hot
engine parts and cause injuries.
xIf it is necessary to work on the fuel system or the electrical system,
please follow the instructions below:
Always disconnect the vehicle battery. When disconnecting the
battery, ensure that the vehicle is unlocked otherwise the antitheft
alarm will be triggered.

Engine coolant
Introduction
Never work on the engine cooling system or if you are not familiar with the
operations to be carried out, the applicable safety standards and especially
if you do not have the instruments, liquids and tools necessary Ÿ! Have
the work carried out by a qualified workshop if you are uncertain. SEAT recom-
mends visiting a qualified workshop.
Negligent work can cause serious injury.

WARNING
Engine coolant is toxic!
xOnly keep engine coolant in its original container, tightly shut and in a
safe place.
xNever store engine coolant in empty food containers or bottles as other
people may accidentally drink it.
xAlways keep engine coolant out of reach of children.
xEnsure that the proportion of engine coolant additive corresponds to
the lowest outside temperature to which the vehicle will be exposed.
xIf the outside temperature is extremely low, the engine coolant could
freeze causing the vehicle to stop. As this would also cause the heating to
stop working, passengers without sufficient clothing could freeze.
For the sake of the environment
Coolants and additives can contaminate the environment. Collect any spilt
fluids in suitable containers and dispose of in accordance with legislation
and with the utmost respect for the environment.
Coolant temperature warning lamp and gauge
When driving normally, the needle will remain in the middle area. The temper-
ature may also rise when the engine is working hard, especially at high
outside temperatures and so the indicator will move quite far to the right-
hand side.
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.

WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
xAlways observe any lit warning lamps and text messages.
xNever ignore the warning lamps or text messages.
xStop the vehicle safely as soon as possible.
Caution
Failure to heed the warning lamps and text messages when they appear may
result in faults in the vehicle.
Engine coolant specifications
The engine cooling system comes with a special mixture of water and at least
40% G 12 plus-plus (TL-VW 774 G) or G 12 plus (TL-VW 774 F) engine coolant
additive. Both are easily recognisable because they are purple in colour.
This mixture gives the necessary frost protection down to -25 °C (-13 °F) and
protects the alloy parts of the cooling system against corrosion. It also
prevents scaling and raises the boiling point of the coolant.
To protect the engine cooling system, the proportion of additive must always
be at least 40%, even if frost protection is not required in countries with a
warm climate.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, decrease
the cooling capacity.
When adding coolant, a mixture of distilled water and at least 40 % of the
additive G 12 plus-plus must be use to ensure optimum rust protection Ÿ.
