the vehicle is moving, the more often the windscreen is cleaned.

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.
