Lights and visibility
● Damaged blades: A film of water on the damaged blades may lengthen
the activ ation time, r
educe the washing intervals or result in a fast and con-
tinuous wipe.
● Insects: insects on the sensor may trigger the windscreen wipers.
● Salt on roads: in winter, salt spread in the roads may cause an extra
long wipe when the w
indscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus effect) or traces of detergent
(car wa
sh) 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 will trigger a single wipe cy-
cle w
ith the rain sensor on. Next the rain sensor detects the reduction in the
sensitive surface area and adapts accordingly. The behaviour of the sensor
will vary with the size of the damage caused by the stone. WARNING
The rain sensor may not detect enough rain to switch on the wipers.
● If necessary, switch on the wipers manually when water on the wind-
sc r

een obstructs visibility. Note
● Clean the sensitive surface of the rain sensor regularly and check the
b l

ades for damage ⇒ fig. 70 (arrow).
● To remove wax and coatings, we recommend a window cleaner contain-
ing alcoho
l. Checking and topping up the windscreen washer bottle

Electronic immobiliser The gear lock prevents the engine from being started with an unauthorised
key
and the

vehicle being moved.
The vehicle key has a built-in chip. It automatically deactivates the immobil-
izer when the key is inserted into the ignition lock.
For this reason, the vehicle can only be used with a genuine SEAT key with
the correct code. Coded keys can be obtained from your Authorised Service
Centre ⇒ page 71. If an unauthorised key is used, the message SAFE or Immobiliser active is
displayed on the instrument panel. The vehicle cannot be started in this
case Note
The correct operation of the vehicle is only guaranteed when original SEAT
key s

are used. Changing gear

Parking sensor system*
Introduction The parking sensor system assists the driver when parking. When the vehi-
cl
e ap
proaches an obstacle, forwards or backwards, an intermittent sound
will be heard, higher or lower depending on the distance. The shorter the
distance, the shorter the intervals between tones. If the vehicle is too close
to the obstacle, the sound signal becomes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
The sensor system on the bumpers transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacle and recep-
tion), this system continuously calculates the distance between the bumper
and the obstacle.
Additional information and warnings:
● Park Assist system ⇒ page 202
● A

ccessories, parts replacement, repairs and modifications ⇒ page 257WARNING
The parking sensor system and the optical parking system cannot re-
pl ac

e driver awareness.
● The sensors have blind spots in which obstacles and people are not
regi
stered.
● Always observe the area around the vehicle, as the sensors do not al-
way
s detect small children, animals or objects. WARNING (Continued)
● The s urface of certain objects and some clothing do not reflect the ul-
tr a

sound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these
types of clothes.
● External sound sources can affect the parking distance aid signals. In
this c
ase, under certain circumstances, people and objects will not be de-
tected. CAUTION
● The sensors may not always be able to detect objects such as trailer
dr a

w bars, thin rails, fences, posts, trees and open boots, etc. This could re-
sult in damage to your car.
● Although the parking sensor system detects and warns of the presence
of an ob
stacle, the obstacle could disappear from the angle of measure-
ment of the sensors if it is too high or low and the system would no longer
indicate it. Therefore, it will not warn you of these objects. Ignoring the
warnings of the parking sensor system could cause considerable damage to
the vehicle.
● The bumper sensors may become damaged or misaligned, for example,
when parkin
g.
● To ensure that the system works properly, the bumper sensors must be
kept c
lean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spra
y the sensors briefly at a distance of no less than 10 cm (4 in-
ches). Note
Acoustic sources may lead to erroneous warnings on the parking sensor
sys t

em, e.g. rough tarmac, cobbles or the noise of other vehicles. 

The parking sensor system assists the driver when parking. If the vehicle is
appro
aching an obstacle, an intermittent sound signal is emitted. The short-
er the distance, the shorter the intervals between tones. If the vehicle is too
close to the obstacle, the sound signal becomes constant. Switching the parking sensor system on and off

Press the  button ⇒ 
fig. 140 when the ignition i
s switched on.
● Automatic on: select r
everse gear.
● Automatic off: drive fa
ster than 15 km/h.
The button lights up when the function is switched on.
Things to note regarding the parking sensor system
● The parking sensor system sometimes registers water on the sensors as
an obs
tacle.
● If the distance does not change, the warning signal will sound less loud-
ly aft
er a few seconds. If the continuous signal sounds, the volume will re-
main constant.
● When the vehicle moves away from the obstacle, the beeping sound au-
tomatic
ally switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
● If the electronic parking brake is engaged or the gear lever is set to P, no
sound wi
ll be emitted.
● Your Authorised Service Centre can adjust the volume of the warning
signal
s. Note
If the parking sensor system is faulty, a constant acoustic signal will be
emitted the fir s

t time it is switched on and the button will flash. Switch the
parking sensor system off using the button and take the vehicle to a spe-
cialist workshop to have the system checked as soon as possible. Safety First Operating instructions Practical tips Technical Data

Park Assist system*
Introduction The Park Assist system helps the driver to find a suitable place to park, to
inser
t
the vehicle into parallel and perpendicular parking places and to
leave parallel parking places.
The Park Assist system is limited to the system abilities and requires that
the driver is especially attentive ⇒  .
The park in

g sensor system is a component of the Park Assist system that
helps to park the vehicle.
For vehicles with the optical parking system, the radio navigation systems
screen displays the detected zones in front of and behind the vehicle, indi-
cating - within the limits of the system - the position of obstacles compared
to the vehicle.
The park assist system cannot be switched on if the factory-fitted towing
bracket is electrically connected to a trailer.

ccessories, parts replacement, repairs and modifications ⇒ page 257 WARNING
Despite the assistance provided by the park assist system, do not run
any ri

sks when parking. The system is not a replacement for driver
awareness.
● Unintentional movements of the vehicle could cause serious injury.
● Adjust your speed and driving style to visibility, road, traffic and
weather c
onditions.
● The surface of certain objects and items of clothing and external
sound sourc
es may have a negative affect on the park assist signals or on
the system sensors or may not reflect its signals.
● The sensors have blind spots in which obstacles and people are not
regi
stered.
● Always observe the area around the vehicle, as the sensors do not al-
way
s detect small children, animals or objects. CAUTION
● The park assist system aims exclusively at other parked vehicles, with-
out t

aking curbs or other circumstances into account. Make sure you do not
damage the tyres and wheel rims when parking. Where necessary, stop ma-
noeuvring to avoid damaging the vehicle.
● The sensors may not always be able to detect objects such as trailer
draw b
ars, thin rails, fences, posts and trees, etc. This could result in dam-
age to your car.
● Although the parking sensor system detects and warns of the presence
of an ob
stacle, the obstacle could disappear from the angle of measure-
ment of the sensors if it is too high or low and the system would no longer
indicate it. Therefore, it will not warn you of these objects. Ignoring the
warnings of the parking sensor system could cause considerable damage to
the vehicle. This is also valid when using the park assist (e.g. to park be-
hind a truck or motorcycle). Therefore, always keep a close watch on the
area in front of and behind the vehicle while parking, and intervene prompt-
ly if necessary. 
