It will light up continuously if the ESP is switched off.
•
It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
 lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully
functional.
Operating the foot brake

The footbrake must be depressed when this warning lamp lights up. This is
necessary when the automatic gearbox* selector lever is moved out of the
positions P or N.Power steering system*

For vehicles with power steering, the level of steering assistance depends on
the vehicle's speed and on the steering angle.
The warning lamp should light up for a few seconds when the ignition is
switched on. It should go out when the engine has started running.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes off after a distance of approx. 50 m.
There is a fault in the electromechanica l steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. The indicator may appear
in two different colours to indicate fault s. If it lights yellow, this indicates a
minor fault. If it lights red, seek wo rkshop assistance immediately, if no
assistance is available stop driving. Stop the vehicle and seek technical
assistance. The power steering does not work if the battery is flat or if the engine is off (for example, for towing). You should take into account that you
will need considerably more power than normal to steer the vehicle if the
steering assistance is reduced
or has failed completely.
Brake pad wear indicator*

As the brake pad wear indicator only monitors the front brake pads, it is advis-
able to have the rear brake pads inspected at the same time.
The instrument panel displays shows the following message
17): CHECK
BRAKE PADS .
WARNING
Have the brake pads inspected immediately by a qualified dealership if the
warning display
 lights up.
Indicator for open doors or tailgate

This indicator lights if one of th e doors or the tailgate is open.The warning light
 should go off when all the doors are closed correctly.
The system also works when the ignition is switched off. It should go off
about 15 seconds after the vehicle is locked.

– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from entering the vehicle.

– Let go of the ignition key as soon as the engine starts; the starter motor must not be allowed to run on with the engine.After starting a very hot engine, you may need to press the accelerator briefly.
When starting from cold, the engine ma y be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine does not start immediately, switch off the starter after about
10 seconds and try again after about half a minute. If the engine still does not
start, the fuel pump fuse should be checked ⇒page 239, “Fuses”.
WARNING
•
Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon mono xide, an odourless and colourless
poisonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also cause death.
•
Never leave the vehicle unattended if the engine is running.
•
Never use “cold start sprays”, they could explode or cause the engine
to run at high revs. Risk of injury.Caution
•
When the engine is cold, you should av oid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.
•
The vehicle should not be pushed or towed for more than approximately
50 metres to start the engine. Fuel could enter the catalytic converter and
damage it.
•
Before attempting to push-start or tow a vehicle to start it, you should first
try to start it using the battery of another vehicle. Note and follow the instruc-
tions ⇒page 255, “Jump-starting”.
For the sake of the environment
Do not warm-up the engine by running th e engine with the vehicle stationary.
You should drive off as soon as you start the engine. This helps the engine
reach operating temperature faster and reduces emissions.Starting diesel engines
The engine can only be started using a genuine SEAT key with
the correct code.– Move the gear lever to the ne utral position and depress the
clutch pedal fully and hold it in this position, the starter will then
only have to turn the engine.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 154, fig. 116 . The
indication lamp

will light for engine pre-heating.
– When the warning lamp goes out, turn the key to position to start the engine. Do not press the accelerator.
– Let go of the ignition key as soon as the engine starts, the starter motor must not be allowed to run on with the engine.
When starting from cold, the engine may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If there are problems starting the engine, see ⇒page 255.

If you wish to equip the car with accessories such as a front spoiler or
wheel covers, it is important that the flow of air to the front wheels is not
obstructed, otherwise the brakes can overheat.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town, drive short distances or have a sporty driving style, we recom-
mend that you have the thickness of your brake pads checked by an Approved
Service Centre more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): The brakes should
be dried by pressing the pedal to restore full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
On steep descents if the brakes are excessively used they will over
heat. Before driving down a long steep gradient, it is advisable to reduce
speed and change to a lower gear (or move the selector lever to a lower gear
if your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.
•
Never let the brakes “rub” by applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not function.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long . This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒page 199, “Modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Power steering (servotronic*)
The power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed to turn the
steering wheel. In cars equipped with servotronic* power steering the degree
of power assistance is regulated electronically according to road speed.
If a fault should occur in the servotronic system the power steering* will still
operate. The degree of power assistance will, however, no longer adapt to

different speeds. If the electronic regu
lating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking) – more effort will be required than usual. The fault
should be corrected by a qualified workshop as soon as possible.
The power steering does not work if the engine is off. In this case the steering
wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary, this will
place an excessive load on the power steering system, Turning the steering
wheel to its limits places a load on the system, which causes noise. It will also
reduce the idling s peed of the engine.
Caution
When the engine is running, do not tu rn the steering wheel to its limits for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
•
If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the car can still be steered. However, more
effort will be required to turn the steering wheel.
•
If the system is leaking or malfunctioning, please take the car to a quali-
fied workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The container is
located in the engine compartment (front left). The correct fluid level in the
reservoir is important for the power steering to function properly. The
hydraulic fluid level is checked at the Inspection Service.

Driving economically and with respect for the
environmentGeneral ObservationsFuel consumption, environmental pollut
ion and wear to the engine, brakes
and tyres depends in large part on your driving style. Fuel consumption may
be reduced from 10 to 15 % by driving defensively and economically. Below
we will give you some suggestions to "alleviate" some of the strain in the
environment and, at the same time, your wallet.
Anticipate the traffic situation well in advance
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you will have to brake less often and, thus, accelerate less. If it is
possible, let the vehicle roll with a gear engaged, for example, if you see a red
light ahead.
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible. We
recommend that, whenever possible, you change to a higher gear upon
reaching 2,000 rpms.
Automatic gearbox: Accelerate slowly and avoid the “kick-down” position. Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to
warm up when it is running at idling
speed. Mechanical wear and pollutan t emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not waste fuel. A well-service d engine gives you the benefit of improved
fuel efficiency as well as maximum reliability and an enhanced resale value.
A maladjusted engine may mean an increase of 10 % over normal fuel
consumption.
Check the oil level every time you fill the tank. Oil consumption depends to a
great extent on the engine load and engine speed. It is quite normal that the
oil consumption of a new engine only reaches its lowest level after a certain
mileage. This means that the oil consumption can only be properly assessed
after about 5,000 km. Depending on your personal driving style, oil consump-
tion can be up to 0.5 litres per 1,000 km.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
leon ingles.book Seite 183 Dienst ag, 11. September 2007 1:47 13

Driving and the environment
184With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumptio n does not regularise until having
driven some four kilometres. This is the reas on why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by
as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
Save electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.
Logbook
A good way of keeping a check on fuel consumption is to take regular notes.
You will be able to note the variations (both positive and negative) and react
accordingly.

Trailer towing
186Trailer towingInstructions to followYour vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 188.
Connector
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available from any SEAT dealer.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted tr ailer weight, you can then climb correspondingly
steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every further 1,000 m (or part thereof). The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit. The figures for
trailer weights and draw bar weights that are given on the
data plate of the towing bracket are for certification purposes only. The
correct figures for your spec ific model, which may be lower than these figures
for the towing bracket, are given in the registration documents ⇒Section
“Technical data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors shoul d be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
