screen may damage the wiper and the wind-
screen wiper motor.
● If necessary, remove snow and ice from the
winds
creen wipers before starting your jour-
ney.
● Carefully lift the frozen windscreen wipers
from the gla
ss. SEAT recommends a de-icer
spray for this operation.
● Do not switch on the windscreen wipers if
the winds
creen is dry. Cleaning with the
windscreen wipers while dry can cause dam-
age.
● In icy conditions, always check that the
wiper bl
ades are not frozen to the glass be-
fore using the wipers. In cold weather, it may
help to leave the vehicle parked with the wip-
ers in service position ›››

● The wind s

creen and window wipers only
function when the ignition is switched on and
the bonnet or rear lid, respectively, are
closed.
● The interval wipe speed varies according to
the vehic
le speed. The faster the vehicle is
moving, the more often the windscreen is
cleaned.
● The rear wiper is automatically switched on
when the winds
creen wiper is on and the car
is in reverse gear. 139

uations
If the vehicle is at a
standstillThe activated position provision-
ally changes to the previous posi-
tion.
During automatic
wipe
The air conditioner comes on for
approximately 30 seconds in air
recirculation mode to prevent the
smell of the windscreen washer
fluid entering the inside the vehi-
cle.
For the interval wipe
Intervals between wipes depend
on the vehicle's speed. The high-
er the vehicle speed the shorter
the intervals. Heated windscreen washer jets
The he

ly thaws the frozen jets, it
does not thaw the water in the washer hoses.
When the ignition is switched on the heated
windscreen washer jets automatically adjust
the heat depending on the ambient tempera-
ture.
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 windscreen wiper lever should
be pul

led 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 cor-
rectly 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 ar

e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake. As you cannot steer and brake in the normal
manner
, ther

e is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leav
e the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
loa d f

or a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● Aft er the en

gine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation. ●

5.Disconnect the electronic parking brake when
you are about to start driving ››› page 172. WARNING
Never leave the vehicle with the engine run-
ning, e s

pecially if a gear or gear range is en-
gaged. The vehicle could then suddenly move
or something strange could happen that
would cause damage, fire or serious injury. WARNING
Cold start sprays could explode or cause a
sud den inc

rease in the engine speed.
● Never use sprays to cold start the engine. CAUTION
● The st ar

ter motor or the engine may be
damaged if you try to start the engine while

● If the engine is cold, avoid high engine
speeds, p
ushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicle or t
owing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not w ait

until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions. ●
Electric a

l components with a high power
consumption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
level
s may briefly increase. This is quite nor-
mal, and no cause for concern.
