“Coming home” and “Leaving home” function (guidance
lights)
The “Coming home” function should be switched on manually. However the
“Leaving home” function is automatically controlled by a photo sensor.
“Coming Home”Necessary operations
To switch sys-
tem on:
– Switch off the ignition.
– Briefly flash the headlights for approximately one sec-
ond ⇒ page 96.
The “Coming home” lighting comes on when the driver's
door is opened. The delay in switching off the headlights
is counted from when the last door or tailgate is closed.
The system
switches off:
– Automatically at the end of the delay period.
– Automatically, if 30 seconds after coming on, a vehicle
door or tailgate remains open.
– If the light switch is turned to position .
– If the ignition is switched on.
“Leaving home”Necessary operationsTo switch sys-
tem on:– Unlock the vehicle when the light switch is in position
 and the photo sensor detects darkness.
The system
switches off:– Automatically, at the end of the delay period.
– When the vehicle is locked.
– When the light switch is turned to position .
– When the ignition is switched on.
Lighting around the exterior mirrors
The lighting around the exterior mirrors illuminates the door area on enter-
ing and leaving the vehicles. It comes on when the vehicle is unlocked,
when the vehicle door is opened and when the “Coming home” or “Leaving
home” function is switched on. If the equipment includes the light sensor,
the lighting around the exterior mirrors only comes when it is dark.
Note
● The time taken for the headlights to go off can be changed in the Lights
& Visibility menu and the function can be switched on or off ⇒ page 62.
● When the “Coming home” function is on, if the vehicle door is opened
there is no audible warning signal to advise that the light is still on. 

Lights and visibility
● 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

as required.
● Open the bonnet  ⇒ page 279.
● The washer bottle is marked with the symbol  on the lid ⇒ fig. 70.
● Check there is enough water in the bottle.
● To top up, mix water with a window cleaner recommended by SEAT ⇒ 
.
Please follow the instructions for use found on the packaging.
● In cold weather, a special antifreeze should also be added to prevent
the water from freezing ⇒

Steering column electronic lock
If the driver's door is opened before the ignition is switched off, the steering
column electronic lock is activated via the ignition key or the sensor built
into the door handle.

Electromechanical power steering
With the power steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel
turning angle. The power steering only works when the engine is running.
You should remember that you will need considerably more power than nor-
mal to steer the vehicle if the power steering is not working correctly or not
at all.
Counter steering assistance system
The counter steering assistance system helps the driver in critical situa-
tions. Additional steering power helps the driver when counter steering. 

Note
● In vehicles with automatic gearbox, the key can only be removed when
the selector lever is in position P.
● After stopping the engine, the engine compartment fan may continue
running for a few minutes, even when the ignition has been switched off or
the key removed. The radiator fan is automatically switched off. 
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. 
