a trailer or on extreme slopes).•The vehicle is fitted with snow chains.•The temporary spare wheel is fitted.•The wheel on one axle is changed.
Tyre pressure adjustment
Following the modification to tyre pressure or after changing one or more
wheels, the button ⇒page 85, fig. 50 must be kept pressed while the igni-
tion is on until an acoustic signal is heard and the warning lamp goes out.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre m onitor
system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure warning lamp

If the tyre pressure warning lamp flashes, this indicates a fault. Go to the
nearest specialised workshop.
WARNING
•When the tyre pressure warning lamp lights up, reduce speed immedi-
ately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.•The driver is responsible for maintaining correct tyre pressures. For this
reason, tyre pressure must be regularly checked.
•Under certain circumstances (for example, when driving in a sportslike
manner, in winter conditions or on a dirt track) the tyre warning lamp may

Driving
164If the engine does not start immediately, switch the starter off after
10 seconds and try again after half a minute. If the engine still does not start,
the fuel pump fuse should be checked ⇒page 254, “Fuses”.
WARNING
•Never start or run the engine in un ventilated or closed rooms. The
exhaust fumes contain carbon monoxide, 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 avoid high engine speeds, driving at
full throttle and over-loading the engine. Risk of engine damage.•The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.•Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and follow
the instructions in ⇒page 267, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle stationary.
Start off immediately, driving gently. 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
its correct code.– Move the gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position.
– Turn the ignition key to position ⇒page 162, fig. 117 . The
indicator lamp
D will light for engine pre-heating.
– When the warning lamp turns off, 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 a very cold engine, it 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 the ⇒ page 267.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while the glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 83 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely run dry, it may take longer than normal
(up to one minute) to start the engine after refuelling with diesel fuel. This is
because the system must eliminate air first.

194change down into a lower gear or range (depending on the type of trans-
mission). This makes use of engine braking and relieves the brakes.•Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•If the brake fluid loses its viscosity and is subjected to heavy use,
vapour bubbles can form in the brake system. This reduces the efficiency of
the brakes.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Before purchasing accessories please
observe the relevant instructions ⇒page 212, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages the catalytic converter.
– Do not let the fuel get too low in the tank. – For engine oil changes, do not replenish with too much engine oil
⇒page 226, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 267.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.•Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.•Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
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

Driving and the environment
196reduce fuel consumption by 10-15%. Some tips on how to help you reduce
pollution while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you 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. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
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 2000 rpm. Follow the recommended gear indication that appears on
the instrument panel ⇒page 62.
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 - 40seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a long time to warm up when it is idling. Mechanical wear
and pollutant 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 consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of
improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
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 .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just one bar too low, fuel consumption can increase 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 year round as they increase fuel consumption 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.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.

Save electricity
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 components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has
Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h•Do not drive with your foot resting on the clutch pedal, as the pressure can
make the plate spin, more fuel will be used and it can burn the clutch plate
lining, causing a serious fault.•Do not hold the vehicle on a hill with the clutch, use the foot brake or hand
brake, using the latter to start. The fuel consumption will be lower and you will
prevent the clutch plate from being damaged.•On descents, use the engine brake, changing to the gear that is more suit-
able for the slope. The fuel consumption will be lower and the brakes will not
suffer.Environmental friendlinessEnvironmental protection is a top priority in the design, choice of materials
and production of your new Seat.
