Malfunctions
The following conditions may prevent the main beam headlight control from
turning off the headlights in time or from turning off altogether:
● In poorly lit towns with highly reflective signs.
● Other insufficiently lit road users (such as pedestrians or cyclists).
● On tight bends and steep slopes (bumps) and when oncoming vehicles
are partially obscured.
● When the drivers of other oncoming vehicles (such as a truck) can see
over a guard rail in the centre of the road.
● If the camera is damaged or the power supply is cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of the camera.
● When the field of vision of the camera is misted up, dirty or covered by
stickers, snow, ice...
WARNING
The convenience features of the main beam assist should not encourage
the taking of risks. The system is not a replacement for driver concentra-
tion.
● You are always in control of the main beam and adapting it to the
light, visibility and traffic conditions.
● It is possible that the main beam headlight control does not recog-
nise all driving situations and is limited under certain circumstances.
● When the field of vision of the camera is dirty, covered or damaged,
operation of the main beam control may be affected. This also applies
when changes are made to the vehicle lighting system, for example, if
additional headlights are installed.
CAUTION
To avoid affecting the operation of the system, take the following points in-
to consideration:
● Clean the field of vision of the camera regularly and make sure it is free
of snow and ice.
● Do not cover the field of vision of the camera.
● Check that the windscreen is not damaged in the area of the field of vi-
sion of the camera.
Note
Main beam and headlight flasher can be turned on and off manually at any
time with the turn signal and main beam lever ⇒ page 107. 
Adjusting the headlights
The light beam of the dipped beam lights is asymmetric: the side of the
road on which you are driving is lit more intensely. 

Fig. 99 In the wind-
screen: Field of vision of
the Lane Assist system
camera
Using the camera located in the windscreen, the Lane Assist system detects
the possible lines dividing the lanes. When the vehicle involuntarily ap-
proaches a dividing line it has detected, the system notifies the driver with
a corrective steering movement . The corrective steering movement can be
overruled at any moment.
No warning is produced with the turn signals activated, given that the Lane
Assist system understands that a lane change is required.
Steering wheel vibration
The following situations cause vibration in the steering wheel and require
the driver to take active control of driving:
● When the limits of the very nature of the system are reached.
● When the maximum rotational torque during the corrective steering
movement is not enough to keep the vehicle inside the lane.
● When no lane is detected during the corrective steering movement. 

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)

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. 
