The intermittent wiper speed varies according to the vehicle speed. The faster
the vehicle is moving, the more often the windscreen is cleaned.
Note
The rear wiper is automatically switched on when the windscreen wiper is
connected and the car is in reverse gear.
Windscreen wiper functions
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.Headlight wash /wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the windscreen
washer is switched on, the headlights are also washed. Therefore, the wind-
screen wiper lever should be pulled towards the steering wheel when the
dipped beam or main beam are on. Any incrusted dirt (such as insects)
should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly in winter, any snow which has
got into the bumper jet supports should be cleaned away. If necessary,
remove snow with an anti-icing spray.
Note
The wiper will try to wipe away any obstacles that are on the windscreen. The
wiper will stop moving if the obstacle blocks its path. Remove the obstacle
and switch the wiper back on again.Windscreen wiper performance in different situations:
If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioning comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen
washer fluid entering the inside of the vehi-
cle.
For the intermittent wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.

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) Ÿpage 189 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 layers
only).
Additional information and warnings:
xSEAT information system Ÿpage 70
xRefuelling Ÿpage 293
WARNING
The auxiliary heater fumes contain carbon dioxide, an odourless and
colourless toxic gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
xNever switch on the auxiliary heater or leave it running in places that
are enclosed or unventilated.
xNever 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.
xAlways 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.
