Driving and the environment 256
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
WARNING
Observe traffic regulations when cleaning the diesel particulate filter while
driving.
xOnly carry on driving if visibility, weather, road and traffic conditions so
permit.
xNever 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 ¬, B or % 0 # 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
working life for the exhaust system and catalytic converter in a petrol engine:
xAlways use unleaded petrol.
xNever run the tank completely dry.
xDo not top up with too much engine oil Ÿpage 309.
xDo not tow-start the vehicle; use the starter cables Ÿpage 371.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 qualified
workshop. If this happens, unburnt fuel can enter the exhaust system and
escape 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 combustion
process, SEAT recommends you avoid frequent short trips.
xAlways use diesel with a low sulphur content Ÿpage 297.
xNever use petrol or fuel oil.
xNever 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 Ÿpage 297.
xNever run the tank completely dry.
xDo not top up with too much engine oil Ÿpage 309.
xDo not tow-start the vehicle; use the starter cables Ÿpage 371.
In order to reduce blocking of the diesel particulate filter, some vehicles with
an automatic gearbox may increase the engine speed slightly to automati-
cally start cleaning the diesel particulate filter. The warning lamp will not light
up in this case
¬.

Trailer towing 258
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 intervals.
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 function
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 Ÿ.

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.
xOnly use a tow hitch in good condition and correctly installed.
xNever change or repair a tow hitch.
xTo 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.
xNever 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.
xAlways secure loads correctly with suitable and undamaged attach-
ment rope or straps.
xAdjust your speed and driving style to visibility, road, traffic and
weather conditions.
xTrailers with a high centre of gravity can overturn more easily than
trailers with a low centre of gravity.
