Opening and closing
● Panor
amic/ti
lting sunroof open (partially or
completely).
● Movement of objects inside the vehicle,
such a
s loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the v

ehicle is relocked and the alarm is
activated without the volumetric sensor func-
tion, relocking will activate the alarm with all
its functions, except the volumetric sensor.
This function is reactivated when the alarm is
switched on again, unless it is deliberately
switched off.
● If the alarm has been triggered by the volu-
metric sensor
, this will be indicated by a
flashing of the warning lamp on the driver
door when the vehicle is opened. The flash is
different to the flash indicating the alarm is
activated.
● The vibration of a mobile phone left inside
the vehic
le may cause the vehicle interior
monitoring alarm to trigger, as both sensors
react to movements and shakes inside the ve-
hicle.
● If on activating the alarm, any door or the
rear lid i
s open, only the alarm will be activa-
ted. The vehicle interior monitoring and the
anti-tow system will only be activated once
all the doors are closed (including the rear
lid). Deactivating the vehicle interior moni-
t
orin
g and anti-t

ow system* When the vehicle is locked, the alarm will be
trigg
er

ed if movements are detected in the
interior (e.g. by animals) or if the vehicle's in-
clination is changed (e.g. during transport).
You can prevent the alarm from being trig-
gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.
● To switch off the interior monitoring and
to w-

away protection, switch off the ignition
and, using the Infotainment system, select:  button >

● When the vehicle is locked now, the vehicle
interior monitorin
g and the tow-away protec-
tion are switched off until the next time the
door is opened.
If the anti-theft security system (Safelock)*
››› page 131 is switched off, the vehicle interi-
or monitoring and the tow-away protection
are automatically switched off. WARNING

Rain sensor off.
Rain sensor on; automatic wipe if neces-
sary.
Setting sensitivity level of rain sensor
– Set control to the right: highly sensi-
tive.
– Set control to the left: less sensitive.
When the ignition is switched off and then
back on, the rain sensor stays on and starts
operating again when the windscreen wipers
are in position 1 and the vehicle is travel-
lin g at
mor

e than 16 km/h (10 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 148 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
0 1
A reduce the effectiveness of the rain sensor or
m
ak
e 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. 148 (arrow).

People who, because of medications, paraly-
si s

or chronic diseases (e.g. diabetes) cannot
perceive pain or temperature, or have a limi-
ted perception thereof, may suffer burns to
the back, buttocks or legs when using seat
heating, an occurrence that may entail a very
lengthy recovery period or from which it may
not be possible to recover fully. Seek medical
advice if you have doubts regarding your
health.
● People with limited pain and temperature
thresho
lds must never use seat heating. WARNING
If the fabric of the cushion is wet, this can ad-
ver sely

affect the operation of the seat heat-
ing, increasing the risk of burns.

● Do not leave clothing that is wet or damp
on the seat. 154

Operation
at a higher speed than the inner wheel. In
thi s
w
ay, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise.
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected, or the ESC in
Sport mode or disconnected.
Multi-collision Brake
In an accident, the multi-collision brake can
help the driver by braking to avoid the risk of
skidding during the accident, which could
lead to further collisions.
The multi-collision brake works for front, side
or rear accidents, when the airbag control
unit records its activation level and the acci-
dent takes place at a speed of over 10 km/h
(6 mph). The ESC automatically brakes the vehicle, as long as the accident has not dam-
aged the ESC, the br
ake hydraulics or the on-
board network
The following actions control automatic brak-
ing during the accident:
● When the driver presses the accelerator,
the automatic
braking does not take place.
● When the braking pressure through press-
ing the brak
e pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
● Multi-collision braking will not be available
if ESC
is malfunctioning. WARNING
● The ESC, ABS, ASR, EDL, el ectr

onic self-
locking differential or selective torque control
systems cannot exceed the limits imposed by
the laws of physics. Always bear this in mind,
especially on wet or slippery roads. If you no-
tice the systems cutting in, you should re-
duce your speed immediately to suit the road
and traffic conditions. Do not be encouraged
to take risks by the presence of more safety
systems. If you do, an accident may occur.
● Please remember that the accident risk al-
way
s increases if you drive fast, especially in
corners or on a slippery road, or if you follow
too close behind the vehicle in front of you.
The ESC, ABS, brake assist, EDL, electronic
self-locking and selective torque control sys-
tems cannot prevent accidents: risk of acci-
dents! ●
Ac c

elerate with caution on slippery surfa-
ces (for example, icy or snow-covered). De-
spite the control systems, the driven wheels
could spin, affecting the stability of the vehi-
cle: risk of accident! Note
● The ABS and ASR w i

ll only operate correctly
if the four wheels have identical tyres. Any
differences in the rolling radius of the tyres
can cause the system to reduce engine power
when this is not desired.
● The regulating processes of the systems
can mak
e noises when they intervene.
● If the warning lamp  lights up
, or  alter-
natively, there could be a fault ››› page 119. Switching on/off the ESC and ASR

Operation
Fatigue detection (break rec-
ommend ation)*
Intr oduction The Fatigue detection informs the driver
when their drivin
g beh
aviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Fatigue
detection sy s

tem tempt you into taking any
risks when driving. Take regular breaks, suffi-
cient in length when making long journeys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of
the driver in al
l circumstances. Consult the in-
formation in the section ››› page 236, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-
vre as driver tiredness.
● No warning is given in the event of the ef-
fect c
alled microsleep!
● Please observe the indications on the in-
strument p
anel and act as is necessary. Note
● Fatigue det ection h

as been developed for
driving on motorways and well paved roads
only.
● If there is a fault in the system, have it
check
ed by a specialised workshop. Function and operation

On the instrument panel display: fa-
tigue det ection symbo
l

. Fatigue detection determines the driving be-
h
av
iour of

the driver when starting a journey,
making a calculation of tiredness. This is
constantly compared with the current driving
behaviour. If the system detects that the driv-
er is tired, an audible warning is given with a
sound and an optic warning is shown with a
symbol and complementary message on the
instrument panel display ››› Fig. 223. The
message on the instrument panel display is shown for approximately 5 seconds, and de-
pending on the ca

se, is repeated. The system
stores the last message displayed.
The message on the instrument panel display
can be switched off by pressing the  button on the windscreen wiper lever or the
b
utt
on  on the multi function steering
wheel

Conditions of operation
Driving behaviour is only calculated on
speeds above about 65 km/h (40 mph) up to
around 200 km/h (125 mph).
Switching on and off

System limitations
The Fatigue detection has certain limitations
inherent to the system. The following condi-
tions can limit the Fatigue detection or pre-
vent it from functioning.
● At speeds below 65 km/h (40 mph)
● At speeds above 200 km/h (125 mph)

Wheels
●
Av oid ru
nning the vehicle on tyres that are
more than 6 years old. If you have no
alternative, you should drive slowly and with
extra care at all times.
● If wheel trims are fitted after the car is pur-
cha
sed, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the l aw

s in the country concerned. Note
● A S EA

T Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● Never mount used tyres if you are not sure
of their “pr
evious history”.
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts
The wheel
bolts
ar
e m
atched to the rims.
When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and correctly shaped bolt
head

s. This ensures that wheels are fitted se-
curely and that the brake system functions
correctly.
The wheel bolts must be clean and turn easi-
ly.
A special adapter is required to turn the anti-
theft wheel bolts* ›››
 page 67.
Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
ma y

lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are m
aintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the ty
res are cold at all times
››› page 291.
● Regularly check the cold inflation pressure
of the tyr
es. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold. ●
Re gu

larly check your tyres for damage and
wear.
● Never exceed the maximum permitted
speed or loa
ds specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
c on s

umption and tyre wear. Note
● Driv ing f

or the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by
SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Re
gularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. 283
