will switch off after a few seconds.
WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the warning lamps and text messages when they appear
may result in faults in the vehicle. Operation mode
Fig. 153 In the sun visor:
Field of vision of the lane
assist system camera.
Using the camera located in the sun visor, 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 will notify the driver
with a corrective intervention. It is possible to override the corrective inter-
vention at any time.
If the turn signal is connected, there will be no warning as the lane assist
system understands that you wish to change lanes voluntarily.
Steering wheel vibration
The following situations cause the steering wheel to vibrate and require the
driver to take active control of the steering:
● If the limits inherent to the system are reached.
● If the maximum rotational torque during the corrective intervention is
not enough to keep the vehicle inside the lane.
● If during the corrective intervention by the system the lane is no longer
detected. 

Note
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when the tyres have not been pierced by these.
● The tyre monitoring system is set to the tyre pressure recommended by
the manufacturer and indicated on the label ⇒ fig. 178.

WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may the damaged resulting in a loss of control of the
vehicle and a serious or mortal accident.
● If the indicator  lights, stop immediately and check the tyres.
● If the tyres are inflated at different pressures or if a tyre pressure is
too low, this will increase tyre wear, negatively affecting vehicle stability
and increasing braking distances. 

232Driving and the environment
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads from the vehicle.
Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds. 

WARNING
Observe traffic regulations when cleaning the diesel particulate filter
while driving.
● Only carry on driving if visibility, weather, road and traffic conditions
so permit.
● Never endanger your safety or that of other road users.
CAUTION
Always pay attention to any lit lamps and to the corresponding descriptions
and instructions to avoid damage to the vehicle.
Note
While the indicators  ,  or  remain lit, there may be engine problems,
fuel consumption may be greater and the engine may lose power. Catalytic converter
The catalytic converter permits the subsequent treatment of the exhaust
gases thus reducing contaminating gas emissions. To ensure a longer work-
ing life for the exhaust system and catalytic converter in a petrol engine:
●
Always use unleaded petrol.
● Never run the tank completely dry.
● Do not top up with too much engine oil ⇒ page 283.
● Do not tow-start the vehicle; use the starter cables ⇒ page 341.
If you should notice misfiring, uneven running or loss of power when the car
is moving, reduce speed immediately. Have the car inspected by a Technical
Service. If this happens, unburnt fuel can enter the exhaust system and es-
cape into the atmosphere. The catalytic converter can also be damaged by
overheating.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel being used. 
Diesel particulate filter
The diesel particulate filter removes soot particulates from the exhaust gas.
The filter retains these particulates and burns them. To assist the combus-
tion process, SEAT recommends you avoid frequent short trips.
● Always use diesel with a low sulphur content ⇒ page 271.
● Never use petrol or fuel oil.
● Never use biodiesel. However, a blend prepared by the diesel manufac-
turer containing biodiesel within the limits established by the EN 590
standard may be used ⇒ page 271. 

In order to reduce blocking of the diesel particulate filter, some vehicles
with an automatic gearbox may increase the engine speed slightly to auto-
matically start cleaning the diesel particulate filter. The warning lamp will
not light up in this case .

Trailer towing
Trailer towing Introduction
Always be aware of the legal requirements for each country to drive with a
trailer and to use a trailer bracket.
Your car is intended mainly for transporting passengers however, it can also
be used to tow a trailer provided that it is fitted with the necessary equip-
ment. The additional load has an effect on the useful life, fuel consumption
and the vehicle performance and, in some cases, reduce the service inter-
vals.
Driving with a trailer requires more force from the vehicle and, thus, more
concentration from the driver.
For wintertime temperatures, fit winter tyres to the vehicle and the trailer.
Drawbar load
The maximum permitted Drawbar load exerted by the trailer drawbar on the
ball joint of the tow hitch must not exceed 100 kg (approximately 220 lbs).
Vehicles with the Start-Stop function
With a SEAT factory fitted or retrofitted trailer bracket, the Start-Stop func-
tion is automatically deactivated when a trailer is connected. For trailer
brackets not installed by SEAT, the Start-Stop function must be deactivated
manually using a button located on the dashboard before driving with a
trailer and it must remain off for the entire journey ⇒ 
.

● Light ⇒ page 95
● Ecological driving ⇒ page 229
● Starter assist systems (Start-Stop function) ⇒ page 196●
Wheels and tyres ⇒ page 297
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
Never transport people in a trailer: this will endanger in their life and is
against the law.
WARNING
The incorrect use of the tow hitch can cause accidents and injury.
● Only use a tow hitch in good condition and correctly installed.
● Never change or repair a tow hitch.
● To reduce the risk of injury in case of a reversing collision, injury to
pedestrians and cyclists when parking, always keep the ball joint in
when a trailer is not being used.
● Never fit a trailer tow hitch “that distributes the load” or “balances
the load”. Your vehicle has not been designed for this type of tow hitch.
The tow hitch may fail and the trailer will separate from the vehicle.
WARNING
Driving with a trailer and transporting heavy or large objects can affect
vehicle handling and even cause an accident.
● Always secure loads correctly with suitable and undamaged attach-
ment rope or straps.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions. 

Trailer towing
Driving with a trailer Technical requirements
If the car is supplied with a factory-fitted tow hitch it will already have the
necessary technical modifications and meet the statutory requirements for
towing a trailer.
Only use an approved trailer hitch for the gross trailer weight rating. The tow
hitch must be suitable for both the vehicle and trailer and must be securely
fitted to the vehicle chassis. Only use a tow hitch with a removable ball
joint. Always check and take into account the tow hitch manufacturer's in-
structions. Never fit a trailer tow hitch “that distributes the load” or “balan-
ces the load”.
Bumper mounted tow hitch
Never fit a tow hitch or its attachments to the bumper. A tow hitch should
never interfere with the bumper performance. Do not modify the exhaust
system and brake system. Regularly check the tow hitch to ensure it is firmly
fitted.
Engine cooling system
Driving with a trailer increases the load on the engine and cooling system.
The cooling system should always have sufficient coolant and to be able to
cope with the vehicle and trailer.
Electric trailer brake
If the trailer has its own braking system, please note the relevant legal re-
quirements. The trailer braking system should never be connected to the ve-
hicle braking system.
Trailer cable
Always use a cable between the vehicle and the trailer ⇒ page 239.Trailer rear lights
The rear lights of a trailer must fulfil the corresponding standards
⇒ page 239.
Never connect the trailer's rear lights directly to the vehicle electric system.
In case of any doubt about the electrical connection of the trailer, ask a spe-
cialised workshop. SEAT recommends visiting a Technical Service.
Wing mirrors
When the field of vision behind the trailer cannot be seen using the stand-
ard wing mirrors of the towing vehicle, additional wing mirrors are required
according to the legal requirements of each country. The wing mirrors must
be fitted before driving and must provide a sufficient field of vision behind.
Trailer electricity consumption
Never exceed the specifications:
Electrical consumerMaximum powerPosition lights and rear lights50 WattsIndicator (each side)54 WattsBrake lights (total)84 WattsReversing lights (total)42 WattsRear fog light42 Watts
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the vehicle causing an accident with serious consequences. 

Trailer towing
The warning lamp
● When the indicator flashes, the tow ball is not in its final position, has
not engaged or is damaged ⇒ 
.
● When the indicator remains lit and the tailgate is open, the tow ball has
inserted correctly into the folded or deployed position.
● When the tailgate is closed, the indicator is turned off.
WARNING
The incorrect use of the tow hitch can cause accidents and injury.
● Ensure that no person, animal or object gets in the way of the tow
ball.
● Never push the button when there is a trailer hitched or when any
kind of carrier or accessory is fitted to the tow hitch ball.
● While the ball is moving, do not interfere with any tool.
● Do not drive with a trailer if the indicator does not light.
● If there is a fault in the electric system or the trailer tow hitch, visit a
specialised workshop to have it checked.
● If the diameter of the tow hitch is less than 49 mm, never use this for
a trailer.
CAUTION
● If anything is attached to the tow hitch ball, do not, under any circum-
stances press the button.
● Never direct a high-pressure or steam cleaning system directly at the
tow hitch ball or trailer power socket. This could cause damage to seals or
remove lubricating grease.
Note
In extremely low temperatures, it is possible that the tow hitch is not re-
leased. In this case, place the vehicle in a warmer location (for example, a
garage). Installing a bicycle carrier to the tow hitch
The maximum load permitted for a bicycle carrier on the tow hitch ball is
75 kg, with a maximum distance of 300 mm from the support. The distance
between supports is the distance between the bicycle carrier centre of gravi-
ty (with the bicycles) and the centre of point of the tow hitch ball.
WARNING
The incorrect use of the tow hitch with a bicycle carrier installed can
cause accidents and injury.
● Never exceed the load and distances between supports indicated.
● Never fit the bicycle carrier to the tow hitch ball neck, underneath the
tow hitch given that the bicycle carrier may be incorrectly fitted due to
the shape of the tow hitch and the model of bicycle carrier.
● Always read and take the manufacturer assembly instructions into ac-
count.
CAUTION
Exceeding the maximum load and distance between supports indicated can
cause considerable damage to the vehicle.
● Never exceed the specifications. 
Hitching and connecting the trailer
Trailer cable
Always secure the trailer cable to the towing vehicle correctly. Leave a little
bit of slack in the cable for turning. However, ensure that the cable does not
rub off the ground while driving. 
