● Damaged blades: A film of water on the damaged blades may lengthen
the activation time, reduce 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 windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus effect) or traces 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 will trigger a single wipe cy-
cle with 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-
screen obstructs visibility.
Note
● Clean the sensitive surface of the rain sensor regularly and check the
blades for damage ⇒ fig. 69 (arrow).
● To remove wax and coatings, we recommend a window cleaner contain-
ing alcohol. Checking and topping up the windscreen washer bottle
with water

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 Technical Services
⇒ 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
keys are used. Changing gear
Introduction
When reverse gear is engaged and the ignition is switched on the following
takes place:
● Reverse lights light up.
● When reversing, the air conditioner automatically changes to air recircu-
lation mode.
● The rear window heater switches on when the windscreen wiper is acti-
vated.
● Also, the parking sensor system, the optical parking sensor and the
camera for the reverse assist system are connected.

Parking sensor system*
Introduction
The parking sensor system assists the driver when parking. When the vehi-
cle approaches 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 204
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
The parking sensor system and the optical parking system cannot re-
place driver awareness.
● The sensors have blind spots in which obstacles and people are not
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
WARNING (Continued)
● The surface of certain objects and some clothing do not reflect the ul-
trasound 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 case, 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
draw 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 obstacle, 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 parking.
● To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray 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
system, e.g. rough tarmac, cobbles or the noise of other vehicles. 

The parking sensor system assists the driver when parking. If the vehicle is
approaching 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. 141 when the ignition is switched on.
● Automatic on: select reverse gear.
● Automatic off: drive faster 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 obstacle.
● If the distance does not change, the warning signal will sound less loud-
ly after 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-
tomatically 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 will be emitted.
● Your Technical Service can adjust the volume of the warning signals.
Note
If the parking sensor system is faulty, a constant acoustic signal will be
emitted the first 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 speci-
alised workshop to have the system checked as soon as possible. 

Park Assist system*
Introduction
The Park Assist system helps the driver to find a suitable place to park, to
insert 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 parking 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.
Additional information and warnings:
● Braking, stopping and parking ⇒ page 185
● Parking sensor system ⇒ page 200
● Caring for and cleaning the vehicle exterior ⇒ page 246
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
Despite the assistance provided by the park assist system, do not run
any risks 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 conditions.
● The surface of certain objects and items of clothing and external
sound sources 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
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
CAUTION
● The park assist system aims exclusively at other parked vehicles, with-
out taking 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 bars, 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 obstacle, 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. 
