parking aid button
Switching on
– Engage reverse gear or
– Press the  button on the centre console ⇒ Fig. 104. A short
confirmation signal will be heard and the button symbol will
light up yellow.
Switching off
– Drive forwards at more than 10 km/h (6 mph), or
– Press the 
button, or
– Switch the ignition off Segments of the visual indication
The distance of separation from the obstacle can be estimated using the
segments around the vehicle. With certain equipment (Radio Standard), the
yellow lines* mark the estimated path, depending on the angle of the
turned steering wheel. A white segment is seen when an obstacle is detec-
ted out of the path of the vehicle. The red segments represent obstacles de-
tected within the path. As the vehicle approaches an obstacle, the seg-
ments are displayed closer to the vehicle. When the penultimate segment is
displayed, this means that the vehicle has reached the collision zone. In the
collision zone the obstacles are represented in red, including those out of
the path. Do not continue to move forward (or backward)

Automatic activation 1)
When the parking aid (ParkPilot) is automatically switched on this is shown
in miniature on the left side of the display.
When slowly approaching an obstacle located in front of the vehicle, the au-
tomatic activation only functions each time the speed is reduced below ap-
proximately 10 km/h (6 mph) for the first time. If the parking aid is deactiva-
ted using the  button, the following actions must be carried out in order
for it to automatically reactivate:
● Switch off the ignition and switch it on again.
● ALTERNATIVELY: Accelerate above 10 km/h (6 mph) before reducing
speed below this number again.
● ALTERNATIVELY: Place the selector lever in position P and then move it
from this position.
● ALTERNATIVELY: Switch on and off the automatic activation in the Easy
Connect system menu.
The automatic activation with parking aid miniature indication can be
switched on and off from the Easy Connect system menu ⇒ page 81:

Intelligent technology
Information recorded in the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the con-
trol units supervise the correct performance of the exhaust gas system and
the airbag systems.
Therefore, while the vehicle is being driven, these electronic control units
are continuously analysing the vehicle data. In the event of faults or devia-
tions from the theoretical values, only this data is stored. Generally, the in-
strument panel warning lamps indicate whether there are any malfunctions.
This data can only be read and analysed using special equipment.
The storing of the data allows specialised workshops to detect and repair
faults. Stored data may include:
● Important data about the engine and gearbox
● Speed
● Direction of travel
● Braking force
● Seat belt check
The vehicle control units never record conversations held by passengers in
the vehicle.
If the control unit records an accident with airbag activation, the system
may automatically send a signal. This will depend on the network operator.
Normally, transmission is only possible in areas with sufficient coverage.
Event Data Recorder
The vehicle is not fitted with an event data recorder.
An event data recorder temporarily stores the vehicle information. There-
fore, in the event of accident, it is possible to obtain detailed information
about how the accident occurred. For example, in vehicles with airbag sys-
tems, data relating to speed of impact, seat belt status, seat positions and airbag activation times may be stored. The volume of data depends on the
manufacturer.
Event data recorders can only be mounted with authorisation from the vehi-
cle owner and, in some countries, they are governed by local legislation.
Reprogramming control units
On the whole, all the data required for the component management is stor-
ed in the control units. The programming of certain convenience functions,
such as the turn signal convenience mode, individual door opening and dis-
play indications can be modified using special equipment at the workshop.
If the convenience functions are reprogrammed, the Instruction Manual in-
formation and descriptions will not coincide with the modified functions.
Therefore, SEAT recommends that any changes are recorded in the “Other
workshop notes section” of the Service Plan.
You can find out about possible reprogramming at your SEAT Official Serv-
ice.
Event recorder
In the footwell on the driver side you will find the diagnostics connection
socket for reading the event recorder. The event recorder stores operating
data and data on the status of the electronic control units. The events re-
corder should only be read and deleted by a SEAT Official Service or special-
ised workshop.
WARNING
The diagnostics connection socket must not be used for private purpo-
ses. Improper use can cause malfunctions: risk of accident!

244Emergencies
Towing and tow-starting the vehicle
General information
Points to observe when tow-starting or towing away If you use a tow rope:
Notes for the driver of the towing vehicle
– The tow rope must be taut before you drive off.
– Release the clutch very carefully when starting the vehicle
(manual gearbox), or accelerate gently (automatic gearbox).
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn signals,
horn, windscreen wipers and washers can be used. Please en-
sure that the steering wheel is unlocked when you switch on the
ignition, and that it moves freely.
– Put the gearbox lever in neutral (manual gearbox) or move the
selector lever to position N (automatic gearbox).
– The brake servo only works when the engine is running. Consid-
erably more effort is required on the brake pedal when the en-
gine is switched off.
– Remember that the brake servo only works when the ignition is
switched on and the vehicle is moving 1)
. Otherwise, considera-
bly more strength than usual will be required when steering. –
Ensure that the tow rope remains taut at all times.
Tow rope or tow bar
It is easier and safer to tow a vehicle with a tow bar. You should only use a
tow rope if you do not have a tow bar.
A tow rope should be slightly elastic to avoid damage to both vehicles. It is
advisable to use a tow rope made of synthetic fibre or similarly elastic mate-
rial.
Only attach the tow rope or the tow bar to the towing rings ⇒ page 245.
Driving style
Towing requires some experience, especially when using a tow rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced drivers should not attempt to tow.
Do not pull too hard with the towing vehicle and take care to avoid jerking
the tow rope. When towing on an unpaved road, there is always a risk of
overloading and damaging the anchorage points.
WARNING
If the vehicle has no electrical power, the brake lights, turn signals and
all other lights will no longer function. Do not have the vehicle towed
away. Failure to do so could result in an accident.
CAUTION
If there is no oil in the gearbox or no lubricant in the automatic transmission
the car may only be towed with the driven wheels lifted clear of the road, or
transported on a special car transporter or trailer. 

Bulbs
Changing a bulb
Changing bulbs requires a certain degree of practical skill. If you choose to change engine compartment lamps yourself, remember
that it is a dangerous area ⇒ 
in Working on components in the engine
compartment on page 209.
Always use identical bulbs with the same designation. The name can be
found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of head-
lights and tail lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light* Full-LED headlight system*
Full-LED headlights handle all light functions (daylight, side light, turn sig-
nal, dipped beam and route light) with light emitting diodes (LEDs) as a
light source.
Full-LED headlights are designed to last the lifetime of the car and light
bulbs cannot be replaced. In case of headlight failure, go to an authorised
workshop to have it replaced.
