Automatic air recirculation mode
Fresh air enters the vehicle interior in position . If the system detects a
high concentration of hazardous substances in the ambient air, air recircu-
lation 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.
With the following outside temperatures and conditions the air recirculation
does not switch on automatically:
● The cooling system is switched on (the AC
button is lit up) and the out-
side temperature is below +3 °C (+38 °F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).

matic air recirculation. The right indicator lamp turns on.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required.
CAUTION
Do not smoke when air recirculation is switched on in vehicles with an air
conditioner. 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
Climatronic: 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.

Auxiliary heater* (additional heater)
Introduction
The auxiliary heater is powered by fuel from the vehicle's fuel tank and can
be used while the vehicle is in motion and at a standstill. Select the mode
required (heat or fan) ⇒ page 166 on the instrument panel.
In winter, the auxiliary heater can be used in heat mode before switching on
the ignition to remove any ice, mist or snow from the windscreen (thin lay-
ers only).
Additional information and warnings:
● SEAT information system ⇒ page 62
● Refuelling ⇒ page 267
WARNING
The auxiliary heater fumes contain carbon dioxide, an odourless and col-
ourless toxic gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never switch on the auxiliary heater or leave it running in places that
are enclosed or unventilated.
● Never program the independent heating system to be activated and
operated in closed, unventilated areas.
WARNING
The components of the auxiliary heater exhaust system heat up a great
deal. This could cause a fire.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass).
CAUTION
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicines and other heat-sensitive objects may be damaged
or made unsuitable for use by the air coming from the air vents.

Things to note
After switching the auxiliary heater off, it continues to run for a short period
to completely burn any fuel remaining in the auxiliary heater. The exhaust
gases are also extracted from the system.

Air conditioning
Checking programming
If the timer has been switched on after switching the ignition off, the instant
on button
will remain lit for around ten seconds.
WARNING
Never program the independent heating system to be activated and oper-
ated in closed, unventilated areas. The auxiliary heater fumes contain
carbon dioxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
Operating instructions
The auxiliary heater exhaust system located below the vehicle must be kept
clear of snow, mud and other objects. The exhaust gases must not be ob-
structed in any way. The exhaust gases generated by the auxiliary heater are
removed via an exhaust pipe fitted underneath the vehicle.
On heating the vehicle interior, depending on the outside temperature the
warm air is first directed at the windscreen and then to the rest of the vehi-
cle interior through the air vents. If the air vents are turned towards the win-
dows, for example, the form of air distribution may be affected.
Depending on the outside temperature, the temperature at which the auxili-
ary heater warms the vehicle interior may be somewhat higher if the heating
or air conditioner temperature control is set to maximum before switching
the heating on.
Depending on the engine, vehicles with auxiliary heater may be fitted with a
second battery in the luggage compartment that is responsible for powering
the auxiliary heater. Cases in which the auxiliary heater will not switch on
●
The auxiliary heater requires about as much power as the dipped beam
headlights. If the battery charge is low, the auxiliary heater will switch off
automatically or will not even switch on. This avoids problems when starting
the engine.
● The heater will switch just once each time. The timer will also have to be
switched back on every time it is required.
Note
● Noise will be heard while the auxiliary heater is running.
● When the air humidity is high and the outside temperature low, the
heating system may evaporate condensation from the auxiliary heater. In
this case, steam may be released from underneath the vehicle. This is com-
pletely normal and there is no need to suspect a fault!
● If the auxiliary heater runs several times over a prolonged period, the ve-
hicle battery may run flat. To re-charge the battery, drive the vehicle for a
long distance. In general: drive for as much time as the auxiliary heating
was working.

SteeringIntroduction
The power steering is not hydraulic but electromechanical. The advantage
of this steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the power steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel
turning angle. The power steering only works when the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 171
● Vehicle battery ⇒ page 291
● Tow starting and towing away ⇒ page 343
WARNING
If the power steering is not working then the steering wheel is much
more difficult to turn and the vehicle more difficult to control.
● The power steering only works when the engine is running.
● Never allow the vehicle to move when the engine is switched off.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.

Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
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.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle. Information on the steering

Electromechanical power steering
With the power steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel
turning angle. The power steering only works when the engine is running.
You should remember that you will need considerably more power than nor-
mal to steer the vehicle if the power steering is not working correctly or not
at all.
Counter steering assistance system
The counter steering assistance system helps the driver in critical situa-
tions. Additional steering power helps the driver when counter steering.

WARNING
Incorrect use of the steering wheel adjustment function and an incorrect
adjustment of the steering wheel can result in severe or fatal injury.
● After adjusting the steering column, push the lever 1
firmly upwards
to ensure the steering wheel does not accidentally change position while
driving.
● Never adjust the steering wheel while the vehicle is in motion. If you
need to adjust the steering wheel while the vehicle is in motion, stop
safely and make the proper adjustment.
● The adjusted steering wheel should be facing your chest and not your
face so as not to hinder the driver's front airbag protection in the event of
an accident.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions to reduce inju-
ries when the driver's front airbag deploys.
● Never hold the steering wheel at the 12 o'clock position or in any oth-
er manner (e.g. in the centre of the steering wheel). In such cases, if the
driver's airbag deploys, you may sustain injuries to your arms, hands and
head.

● The engine should only be switched off when the vehicle is at a
standstill.
WARNING
While the engine is running or starting it could help reduce the risk of se-
rious injury.
● Never start or leave the engine running in poorly ventilated or closed
spaces. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never leave the vehicle unattended if the engine is running. The vehi-
cle could move off suddenly or something unexpected could happen re-
sulting in damage and serious injury.
● Never use start boosters. Cold start sprays could explode or increase
the engine speed unexpectedly.
