Driving and the environment 252
Ecological driving
Introduction
Fuel consumption, environmental impact and engine, brake and tyre wear
depend largely on three factors:
xPersonal driving style.
xConditions of use (weather, road surface).
xTechnical requirements.
Savings of up to 25% in fuel consumption are possible with an appropriate
driving style and the adoption of certain simple tips.
WARNING
Always adapt your speed and the distance to the vehicles ahead in line
with visibility, weather conditions, the condition of the road and the traffic
situation.
Economic driving style
Changing gear early
General instructions: The highest gear is always the most economical gear.
As a guideline, for the majority of vehicles: At a speed of 30 km/h, drive in
third gear, at 40 km/h in fourth gear and at 50 km/h in fifth gear.
In addition, skipping gears when shifting up helps to save fuel, weather and
traffic conditions permitting.
Do not wait until the last moment before changing gear. Only use first gear
when you move off and change to second gear quickly. Avoid the kick-down
function in vehicles with automatic gearbox.Vehicles with a gear display help to achieve an economical driving style as
the display indicates the best moment to change gear.
Let the vehicle roll
If you take your foot off the accelerator, the fuel supply is stopped and
consumption is reduced.
Allow the vehicle to roll without accelerating, for example when approaching
a red traffic light. However, if the vehicle is rolling too slowly or the distance
is too long, the clutch pedal should be pressed to declutch. The engine will
then operate at idle speed.
If the vehicle is going to be at a standstill for a period of time, switch off the
engine; for example, while waiting at a level crossing. In vehicles which have
the Start-Stop function on, the engine switches off automatically when the
vehicle is not moving.
Think ahead and “flow” with the traffic
Frequent acceleration and braking considerably increase fuel consumption. If
you think ahead as you drive and keep a safe distance from the vehicle in
front, it is possible to slow down by simply lifting your foot off the accelerator.
This eliminates the need for constant braking and acceleration.
Calm and steady driving
Constancy is more important than speed: The more you drive at a constant
speed, the lower the fuel consumption.
When driving on the motorway, it is more efficient to drive at a constant and
more moderate speed than to be continuously accelerating and braking. As a
general rule, you will reach your destination just as quickly when you drive at
a constant speed.
The cruise control function helps you to achieve a constant style of driving.
Moderate use of additional electrical appliances
It is important to travel in comfort, but convenience systems should be used
in an ecological manner.

Driving and the environment253
Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Some equipment, when connected, increase fuel consumption considerably,
for example:
xAir conditioning cooling system: If the air conditioning system is required
to cool to significantly lower temperatures than the true outside temperature,
it will require a large quantity of energy from the engine. Therefore, we recom-
mend that the selected temperature for the vehicle is not too different to the
outside temperature. It is a good idea to open all the windows of the car
before starting your journey, and to drive a short distance with all the
windows open to allow the vehicle to cool down slightly. Only then should
you close all the windows and switch on the air conditioning. Keep windows
closed when travelling at high speeds. Driving with the windows open
increases fuel consumption.
xSwitch off the seat heating when the seats have warmed up.
xSwitch off the heated rear window and the windscreen heating when the
windows have demisted and are free of ice.
xDo not leave the independent heating switched on when the vehicle is
moving Ÿpage 187.
Other factors which increase fuel consumption (examples):
xFault in engine management.
xDriving on hills.
xTrailer towing.
Saving fuel while driving
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%.
A vehicle uses most fuel when accelerating. By anticipating the traffic situa-
tion ahead, you will brake and therefore accelerate less. Wherever possible,
let the car roll slowly to a stop, for instance when you can see that the next
traffic lights are red.
Avoid short journeys
Fuel consumption is much higher when the engine is cold, immediately after
it has been started. It takes a few kilometres of driving for the engine to warm
up and to normalise consumption.
The engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions. The
ambient temperature has a decisive influence.
fig. 162 shows the difference in consumption for the same journey at +20 °C
(+68 °F) and at -10 °C (+14 °F).
Fig. 162 Fuel consump-
tion in litres per 100 km at
different outside tempera-
tures.

Driving and the environment 254
Unnecessary short journeys should be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in summer, even when other condi-
tions are the same.
“Warming” the engine is not only forbidden in some countries, but in practice
it is technically superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres helps to reduce rolling resistance
and, as a result reduces fuel consumption. Increasing the tyre pressure
slightly (+ 0.2 bar / + 3 psi) can help to save fuel.
If you are prepared to accept a slight reduction in comfort, the tyres may be
filled to the pressures recommended for a fully-loaded vehicle. This is also
valid when driving alone without luggage.
When you buy new tyres, make sure they are optimised for minimum rolling
resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils, known as low friction engine oil,
help to reduce fuel consumption. Low friction engine oils reduce the resist-
ance caused by friction in the engine, they flow around the engine more
quickly and efficiently, particularly in cold starts. The effect is particularly
noticeable in vehicles frequently used for short journeys.
Always check the engine oil level and observe service intervals (engine oil
change intervals).
When purchasing engine oil, always observe legal requirements and ensure
that the oil is approved by SEAT.
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 consumption
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. Optional
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.

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
¬.

xAvoid brusque manoeuvres and sudden braking.
xAlways take the following precautions seriously.
xReduce your speed immediately if you observe the trailer rocking from
side to side.
xNever drive at more than 80 km an hour when towing a trailer (or 100
km an hour in exceptional circumstances). This also applies in countries
where higher speeds are permitted. Always take the speed limits for vehi-
cles with and without trailers in each country into account.
xNever try to stop the “snaking” by increasing speed.
WARNING
When driving with a trailer and using a trailer hitch that was not installed
by SEAT, the Start-Stop function must be manually deactivated. Otherwise,
this could cause a braking anomaly that could result in an accident with
serious consequences.
xAlways manually deactivate the Start-Stop function when a trailer is
being used on a trailer hitch that has not been installed by SEAT.
Note
Always turn off the anti-theft alarm system before connecting or discon-
necting a trailer Ÿpage 88. Otherwise, the tilt sensor may erroneously acti-
vate the alarm.
Note
Never use a trailer with a new engine (for the first 1000 km or 600 miles)
Ÿpage 285.
Note
At SEAT, we recommend folding in the trailer hitch ball when a trailer is not
being used. In case of a rear collision, the damage caused to the vehicle with
the extended trailer hitch ball could be more extensive.
Note
In some models, a trailer hitch is necessary for towing vehicles. For this
reason, you should store the tow hitch in the vehicle at all times.
WARNING (continued)

Trailer towing 260
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 instruc-
tions. Never fit a trailer tow hitch “that distributes the load” or “balances 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
requirements. The trailer braking system should never be connected to the
vehicle braking system.
Trailer cable
Always use a cable between the vehicle and the trailer Ÿpage 262.Trailer rear lights
The rear lights of a trailer must fulfil the corresponding standards
Ÿpage 262.
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
specialist workshop. SEAT recommends visiting a qualified workshop.
Wing mirrors
When the field of vision behind the trailer cannot be seen using the standard
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:
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the vehicle causing an accident with serious consequences.
Caution
xIf the rear lights of the trailer are not correctly connected, the vehicle elec-
tronics may be damaged.

xIf the trailer absorbs excessive electric current, the vehicle electronics
may be damaged.
xNever connect the trailer's electric system to the electrical connections of
the rear lights or any other power sources. Only use suitable connections for
providing electric current to the trailer.
Note
Towing a trailer places additional demands on the vehicle. At SEAT, we recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
Note
In some countries, an additional fire extinguisher is required if the trailer
weight is more than 2500 kg
Electric tow hitch ball
The rotation radius of the tow hitch ball should be free of people, animals and
objects Ÿ.

Trailer towing263
Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Trailer electric socket
The electric connection between vehicle and trailer is a 13-pin socket. If the
trailer plug has seven pins, an adapter cable must be used.
Trailer rear lights
Check the trailer rear lights to ensure they work correctly and remain legal.
Ensure that the trailer does not use more than the maximum power
Ÿpage 260.
Trailer connected to the antitheft alarm:
xWhen a vehicle comes from the factory fitted with an antitheft alarm and
tow hitch.
xWhen the trailer is connected to the vehicle using the socket.
xWhen the vehicle and trailer electrical systems work correctly and are not
damaged.
xWhen the vehicle is locked using the vehicle key and the antitheft alarm
is turned on.
When the vehicle is locked, the alarm is triggered when the electrical connec-
tion between the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system before connecting or discon-
necting a trailer. Otherwise, the tilt sensor may erroneously activate the
alarm.
WARNING
Erroneous or unsuitable connection of electric cables may supply energy to
the trailer causing an anomaly in the vehicle electronics that could result
in an accident with serious consequences.
xAll work on the electrical system must be carried out only by a
specialist workshop.
xNever connect the trailer's electric system to the electrical connections
of the rear lights or any other power sources.
Caution
Do not leave the trailer connected to the vehicle when parked; places on its
support wheel or its supports. For example, when changing the load or a
puncture, the vehicle will be pushed up or down. The force acting on the tow
hitch and the trailer could damage the vehicle or the trailer.
Note
In case of a fault in the vehicle or trailer electrical system or in case of prob-
lems with the antitheft alarm system, have the system checked by a specialist
workshop.
Note
If the trailer accessories use energy from the socket when the engine is
stopped, the battery will be discharged.
Note
For technical reasons, trailers fitted with rear LED lights cannot be connected
to the antitheft alarm system.
Note
If the vehicle battery is running low, the electrical connection with the trailer
is automatically cut.
Note
With the engine running, the electrical equipment on the trailer will consume
power.

xAs of the combined vehicle and trailer mass, braking distances will be
greater.
xSelect a low gear before driving down a steep hill to use the engine
braking effect to slow down the vehicle. Otherwise, the braking system could
overheat and fail.
xThe vehicle centre of gravity and handling change because of the trailer
load and because of the increased combined mass of the vehicle and trailer.
xIf the towing vehicle is empty and the trailer loaded then the load distri-
bution is incorrect. If you must travel in these conditions, drive carefully and
reduce your speed accordingly.
Hill starts with a trailer
Depending on the hill and the gross combined weight, it is possible that the
combined vehicle and trailer move backwards slightly when starting.
For a hill start with a trailer, proceed as follows:
xPress and hold the brake pedal.
xPress the button once to turn off the electric parking brake
Ÿpage 210.
xPress and hold the button to hold the vehicle and trailer combination
using the parking brake.
xWith a manual gearbox: press the clutch pedal to the floor.
xEngage first gear or the gear range D Ÿpage 201, “Changing gear”.
xRelease the brake pedal.
xMove off slowly. To do this, gently release the clutch pedal (for manual
gearbox).
xRelease the button only when the engine provides sufficient power to
move the vehicle and trailer combination.
WARNING
Jerking the trailer in an unsuitable manner could cause loss of vehicle
control with the subsequent serious consequences.
xDriving with a trailer and transporting heavy or a large objects will
change the vehicle handling and braking distances.
xAnticipate traffic and be extremely cautious. Brake early.
xAdjust your speed and driving style to visibility, road, traffic and
weather conditions. Reduce your speed, especially on steep hills.
xAccelerate gently and carefully. Avoid brusque manoeuvres and sudden
braking.
xAlways take the following precautions seriously. Reduce your speed
immediately if you observe the trailer rocking from side to side.
xNever try to stop the “snaking” by increasing speed.
xAlways take the speed limits for vehicles with and without trailers in
each country into account.
Stabilising the vehicle and trailer combination
Stabilisation of the vehicle and trailer combination is an extension of the
electronic stability programme (ESP) and helps, with the assistance of the
trajectory control, to reduce trailer “snaking”.
Stabilisation of the vehicle and trailer combination is active when the ESP
«
indicator on the dashboard remains lit for about two seconds more than the
ABS indicator.
Requirements for stabilising the vehicle/trailer combination
xAn original tow hitch is fitted by the manufacturer or a compatible model
is retrofitted.
xThe ESP is on. The warning indicator in the control panel « is not lit.
xThe trailer is connected to the vehicle using the socket.
xThe vehicle is driven faster than 60 km/h.
