Operation
Rain sensor modified behaviour
P o
s
sible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 144 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may
reduce the effectiveness of the rain sensor or
make it react more slowly, later or not at all.
● Cracked windscreen: the impact of a stone
wil
l trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor will vary with the size of the damage
caused by the stone. WARNING
The rain sensor may not detect enough rain
to sw it

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. Note
● Cle

an the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 144 (arrow).
● To remove wax and coatings, we recom-
mend a window c
leaner containing alcohol. Rear vision mirror

Your vehicle is fitted with an interior rear vi-
sion mirror with a manual or automatic* con-
trol for anti-dazzle position.
Interior rear vision mirror with manual set-
ting for anti-dazzle position
– Position the small lever of the lower edge
of the mirror t

o face towards the rear. WARNING
In the event that an automatic anti-dazzle
re ar

vision mirror breaks, an electrolyte fluid
may leak. This could cause irritation to the
skin, eyes and respiratory organs. If you
come into contact with this liquid, it must be
rinsed with large quantities of water. If neces-
sary, get medial help. CAUTION
In the event that an automatic anti-dazzle
re ar

vision mirror breaks, an electrolyte fluid
may leak. This liquid attacks plastic surfaces.
Clean it with a wet sponge as soon as possi-
ble. Note
● If the light inc

ident in the interior rear vi-
sion mirror is obstructed (e.g. with the sun
blind*, the anti-dazzle rear vision mirror with
automatic setting will not operate perfectly.
● When the interior lights are on or reverse
gear en
gaged, the rear vision mirrors do not
darken with automatic adjustment for anti-
dazzle position. 138

Transport and practical equipment
●
For the r e
ar seat seat belts to offer the nec-
essary protection all the parts of the rear
backrest must be properly engaged. This is
particularly important in the case of the cen-
tre rear seat. If someone is seated in a seat
whose backrest is not properly engaged they
will fly forward, along with the backrest, dur-
ing an accident or a sudden driving or braking
manoeuvre.
● A red signal on the button 2 warns that
the bac k

rest is not engaged. Always check
that the red marking is not visible when the
backrest is in the upright position.
● When the rear seat backrest is lowered or is
not properly
engaged nobody else can travel
in the corresponding seats (not even a child). CAUTION
Serious damage can be caused to the vehicle
and other ob j

ects if the rear seat backrest is
lowered or lifted without due care and atten-
tion.
● Before lowering the rear seat backrest, al-
way
s adjust the front seats so that neither
the head restraints nor the cushions of the
rear backrest can hit them. Transport and practical

could spill and cause burns, which may cause
an accident.
● Do not use hard china cups or glasses.
These cou
ld cause injury in the event of an

All luggage and other loose objects must be
safely secured in the luggage compartment.
Unsecured objects which shift back and forth
could impair the driving safety or driving
characteristics of the vehicle by shifting the
centre of gravity. – Distribute the load evenly in the luggage
comp ar

tment.
– Place heavy objects as far forward as possi-
ble in the lug

gage compartment.
– Place the heavy objects first.
– Secure heavy objects to the fitted fastening
rings

›››
page 153. WARNING
● Loo se lug

gage and other objects in the lug-
gage compartment could cause serious inju-
ries.
● Always stow objects in the luggage com-
partment
and secure them on the fastening
rings.
● Use suitable straps to secure heavy ob-
jects.
● D

uring sudden manoeuvres or accidents,
loose ob
jects can be thrown forward, injuring vehicle occupants or passers-by. This in-
cr
e

ased risk of injury will be further increased
if a loose object is struck by an inflating air-
bag. If this happens, objects may shoot out-
ward like a missile. Risk of fatal injury.
● Please note that the centre of gravity may
shift when tr
ansporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never exceed the allowed axle weights or
allo
wed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Never leave your vehicle unattended, espe-
cia
lly when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehic
le. Close and lock all the doors and
rear lid when you leave the vehicle. Before
you lock the vehicle, make sure that there are
no adults or children in the vehicle. Note
● Air cir c

ulation in the vehicle helps reduce
fogging of the windows. Used air escapes
through ventilation slits in the side trim of
the luggage compartment. Ensure that the
ventilation slots are never covered. ●

Operation
WARNING
Reduced visibility through the windows in-
cr e
ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● Swit c

h the air conditioner off if you think it
may be broken. This will avoid additional
damage. Have the air conditioner checked by
a specialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. SEAT rec-
ommends visiting a SEAT Official Service. Note
● When the coo lin

g system is turned off, air
coming from the outside will not be dried. To
prevent fogging of the windows, SEAT recom-
mends leaving the cooling system (compres-
sor) turned on. To do this, press the button  . The button lamp should light up.
● The maximum heat output required to de-
fro s

t windows as quickly as possible is only
available when the engine has reached its
normal running temperature.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over. Adjust using the Easy Connect sys-
