Coming/leaving home function*
The Coming Home function is controlled manually. The Leav-
ing Home function is controlled with a photosensor.
If the Coming Home or Leaving Home function is connected, the front side
and dipped lights, the tail lights and the number plate light will light up to
provide assistance.
Coming home function
The Coming Home function is activated by switching off the ignition and
briefly flashing the lights. When the driver door is opened, the Coming
Home lighting comes on. If the driver door is already open when the lights
are flashed briefly, the Coming Home lighting comes on immediately.
When the last door of the vehicle or the rear lid is closed, the Coming Home
function starts and the switching off the headlights is delayed.
The Coming Home lighting switches off in the following cases:
● On completion of the time period established for the delay in switching
off the lights after all the vehicle doors and the rear lid have been closed.
● If, 30 seconds after being connected, any doors or the rear lid remain
open.
● If the light switch is turned to position .
● If the ignition is switched on. Leaving home function
The Leaving Home function is activated when the vehicle is unlocked if:
●
the light control is in position  and
● the photosensor detects “darkness”.
The Leaving Home lighting switches off in the following cases:
● If the time period for the delay in switching off the headlights has ended
● If the vehicle is locked again.
● If the light switch is turned to position .
● If the ignition is switched on.
Note
The setting for the delay in switching off the headlights in the Coming Home
and Leaving Home function can be changed or the function can be connec-
ted or disconnected in the menu Lights and visibility ⇒ page 74.
● If the ignition key is removed while the lights are on, and the lights are
flashed briefly and the driver door opened, no audible warning is heard, as
when the Coming Home function is on, the lights are automatically switched
off after a period of time (except when the light switch is in position  or

Parking aid acoustic system*
General notes
Various parking aid systems are available to help you when parking or ma-
noeuvring in tight spaces, depending on the equipment fitted on your vehi-
cle.
The SEAT Parking System* gives an audible warning if there are any obsta-
cles behind your vehicle.
When you are parking, the SEAT Parking System Plus* warns you acoustical-
ly and optically 1)
about obstacles “in front of” and “behind” the vehicle.
Note
To ensure the acoustic parking aid works properly, the sensors must be kept
clean and free of snow and ice. SEAT Parking System: Description
The Parking System is an acoustic parking aid.
Sensors are located in the rear bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings. The measuring range of the sen-
sors starts at approximately:
RearSide0.60Centre1.60
The audible warnings sound with increasing frequency as you approach the
obstacle. When the vehicle is less than 0.30 m away from the obstacle, the
warning tone will sound continuously. Do not drive on!
The volume of the warning beeps will be gradually reduced after about four
seconds if the vehicle remains at a constant distance from a detected obsta-
cle (it does not affect the permanent audible warning).
The parking aid is switched on automatically when reverse gear is engaged.
You will hear a brief confirmation tone.
WARNING
● The parking aid is not a replacement for driver awareness. The driver
is personally responsible for safe parking and other manoeuvres.
● The sensors have blind spots in which obstacles are not registered.
Always look out for small children and animals because the system will
not always detect them. Always pay attention when reversing to avoid ac-
cidents.
● Always keep a close eye on the area around the vehicle and make full
use of the rear vision mirrors. 

Driving
CAUTION
Please note that low obstacles detected by the system may no longer be
registered by the sensors as the vehicle moves closer, so the system will not
give any further warning. Certain kinds of obstacles (such as wire fences,
chains, thin painted posts or trailer draw bars, etc) may not always be de-
tected by the system, so take care not to damage the vehicle in such cases.
Note
Please refer to the notes on towing ⇒ page 192. 
SEAT Parking System Plus*: Description
The Parking System Plus is an acoustic and optical parking
aid.
Sensors are located in the front and rear bumpers. When the sensors detect
an obstacle, you are alerted by audible and optical warnings. The measur-
ing range of the sensors starts at approximately:
FrontSide0.90Centre1.20
RearSide0.60Centre1.60
The audible warnings sound with increasing frequency as you approach the
obstacle. When the vehicle is less than 0.30 m away from the obstacle, the
warning tone will sound continuously. Stop moving immediately!
The volume of the warning beeps will be gradually reduced after about four
seconds if the vehicle remains at a constant distance from a detected obsta-
cle (it does not affect the permanent audible warning). Activating/Deactivating

Fault messages
If you hear a long beep for a few seconds and the LED on the switch *
starts flashing when you switch on the parking aid, a system fault has oc-
curred. Please refer the problem to a SEAT Official Service or specialised
workshop.
Note
If the fault is not corrected before you switch off the ignition, it will only be
indicated by the flashing LED on the switch  the next time you switch on
the parking aid. 

198Intelligent technology
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off by briefly pushing the button on the centre con-
sole.
When the ASR is switched off, the  OFF
warning lamp will light up. The ASR
should normally be left on. Only in exceptional circumstances, when the
slipping of the wheels is required, it will be necessary to have it disconnec-
ted, for example.
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The ASR should be switched on again as soon as possible.
WARNING
● Remember that not even the ASR can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ASR should not
encourage you to run any risks.
CAUTION
● To ensure that the ASR works correctly, identical tyres should be fitted
on all four wheels. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS and ASR. XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer 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 under-
steer or “lengthening” of the trajectory.
The XDS system can detect and correct this effect via the sensors and sig-
nals 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 the ASR traction control is disconnected.

Electronic Stability Control (ESC)*
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control (ESC) includes the ABS, EDL, ASR and Steer-
ing manoeuvre recommendation systems. 

199
Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESC. This function
aids the driver to better stabilize the vehicle in a critical situation. For exam-
ple, in case of sudden braking surface with varied adherence, the vehicle
will tend to destabilise its trajectory to the right or to the left. In this case,
the ESC recognises the situation and assists the driver with a counter steer-
ing manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
● Remember that not even the ESC can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works correctly, all four wheels must be fitted
with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. 
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 197. 
Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 83.
At speeds of up to approximately 80 km/h, it is able to balance out differen-
ces in the speed of the driven wheels of approximately 100 rpm caused by a
slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the oth-
er driven wheel via the differential. 
