the engine to cool and check the coolant level Ÿ .
Even if the coolant level is correct do not continue driving. You should obtain
technical assistance.
WARNING
Read and observe the warnings “Working in the engine compartment”
before opening the bonnet to carry out work in the engine compartment.
Caution
Accessories in front of the air inlet reduce the cooling effect of the coolant. At
high outside temperatures and high engine loads, there is a risk of the
engine overheating.
Fuel gauge z
The fuel tank has a capacity of approx. 70 litres.
When the needle reaches the reserve zone Ÿfig. 46 -arrow-, the warning
lamp z lights up in the display. The text
6) PLEASE REFUEL may appear in the
combi-instrument display. At the same time, an audible warning is given as a
reminder to fill up. At this point there are still about 8 litres of fuel in the
tank.

Coolant Level* / temperature v
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
•The warning symbol does not go out again after a few seconds.
•The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals Ÿ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary Ÿpage 241.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch off the engine. Contact an Authorised Service Centre
or a qualified workshop.
Coolant level too low
The following information text is displayed in the instrument panel display:
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity Ÿ.
WARNING
•If your vehicle is immobilised for any technical reasons, move it to a
safe distance from traffic. Turn off the engine, turn on the hazard lights and
place the warning triangle.
•Never open the bonnet if you can see or hear steam or coolant escaping
from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
•The engine compartment of any motor vehicle is a dangerous area!
Before carrying out any work in the engine compartment, switch off the
engine and allow it to cool down. Always note the corresponding warnings.

The corresponding warning is:
STOP CHECK LEVEL COOLANT
SERVICE MANUAL.
If the symbol flashes while driving, this means that either the coolant temper-
ature is too high or the coolant level is too low. Stop immediately, switch off
the engine and check the level. Top up coolant if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. In this case, check the radiator fan fuse, and replace if
necessary.
If the warning light does not go out, although the coolant level is correct and
the fan fuse is correct, do not continue driving. Obtain technical assistance.
If the fault is only in the radiator fan, it is possible to continue driving as far
as the nearest Technical Service Centre, as long as the coolant level is correct
and the display light is off.

The corresponding warning is:
ALTERNATOR WORKSHOP!
The warning lamp lights up when the ignition is switched on. It should go out
when the engine is started.
The alternator is operated by a long-lasting drive belt.
If the warning light lights up while driving, stop, switch off the engine and
check the drive belt. If the belt is loose or broken, do not continue driving, as
the coolant pump will not be driven. The belt should be checked or replaced.If the warning light comes on even though the belt is neither loose nor
broken, it is usually possible to continue driving to the nearest Technical
Service Centre.
As the vehicle battery will discharge, it is advisable to switch off all non-vital
electrical consumers.
Seat belt warning lamp
h
The corresponding warning is:
FASTEN SEAT BELT
This warning light (only in some countries) lights up for approximately 6
seconds when the ignition is switched on to remind occupants to fasten seat-
belts. If the seat belts are not fastened, a sound signal is emitted when the
ignition is switched on which will stop when the seat belts are fastened or
after approximately 6 seconds.
WARNING
•If the brake fluid level is below the “MIN” mark, you should wait for
assistance from specialised personnel before continuing to drive.
•If the fluid level is correct, the fault may lie in the ABS. If the ABS control
system fails, the rear wheels may block rapidly on braking. This, in certain
circumstances, could cause the vehicle to skid.
•Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Risk of burns. Wait until you can no longer see or
hear escaping steam or coolant.
•Do not touch the fan, as it could suddenly start to operate, even if the
ignition is switched off.
•To prevent burns from boiling coolant, the following should be
observed:
•Take care when opening the coolant expansion tank!. When the engine
is warm or hot, the system is pressurised! Therefore wait until the engine
cools before opening the cap.

Intelligent technology 182
•If the brake warning lamp H should light up together with the ABS
warning lamp J, stop the vehicle immediately and check the brake fluid
level in the reservoir Ÿpage 221. If the fluid level has dropped below the
“MIN” mark you must not drive on. Risk of accident. You should obtain
professional assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS control function. This could cause the
rear wheels to lock quickly when you brake. This could cause the tail of the
vehicle to skid sideways. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
The electronic differential lock (EDL) only works when the engine is running.
EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
It uses the ABS sensors to monitor the speed of the driven wheels.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The car remains operational
and will behave in the same way as a car without EDL. For this reason, the
driver is not informed that the EDL has been switched off.The EDL will switch on again automatically when the brake has cooled down.
WARNING
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may other-
wise start to spin. This could impair the car's stability.
•Always adapt your driving style to suit road conditions and the traffic
situation.
WARNING
Modifications to the vehicle or work carried out incorrectly (e. g. to the
engine, the brake system, running gear or any components affecting the
wheels and tyres) could affect the efficiency of the ABS, EDL, ESP and TCS
and lessen their efficiency.
Electronic stabilisation programme (ESP)
The electronic stabilisation programme helps to reduce the
danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS
and only works when the engine is running.
The ESP should generally be left switched on at all times. Only when the
necessary drive can not be obtained should the ESP be disconnected.
For example:
•when driving with snow chains,
WARNING (continued)

Driving and the environment 186
If you drive with wet brakes, for example after driving through water, after
heavy rainfall or after washing the car, the braking effect will be reduced as
the brake discs will be wet, or possibly frozen (in winter): the brakes must be
“dried” through careful braking.
The brake fluid must be changed every two years at the latest. Heavy use of
the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. This prevents the brakes developing their 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. The slightly reduced braking effect can be compen-
sated for by increasing pressure on the brake pedal. 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.
•When driving downhill, the brakes work hard and get hot very quickly.
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). In this way you will make use of
the engine braking effect and relieve the load on the brakes.
•Never let the brakes “rub” by only 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 work.
•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 notes Ÿpage 202 before
buying accessories.
•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gasses purification system
Catalytic converter*
To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil
Ÿpage 215, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary
Ÿpage 249.
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 qualified workshop. These symptoms are indicated by the exhaust
gas warning lampŸpage 70. If this happens, unburnt fuel can enter the
exhaust system and escape into the environment. The catalytic converter can
also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!
WARNING (continued)

Driving and the environment187
Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a
•Never park where the catalytic converter could come into contact with
dry grass or inflammable materials under the vehicle.
•Do not apply additional undercarriage protection or anti-corrosion coat-
ings to the exhaust pipes, catalytic converter or the heat shields on the
exhaust system, because the heat from the engine could ignite these.
Caution
Never fully drain the fuel tank, in this case, 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 under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be reme-
died by changing to another brand of fuel.
Diesel particle filter
The diesel particle filter retains and burns the soot derived
from the combustion process.
The diesel particle filter system is made up of the following elements:
•Additive deposit with integrated pump
•Additive
•Diesel particle filter
•Lambda probeThe diesel particle filter removes practically all the particles of soot from the
exhaust gas. The filter retains these particles and burns them.
By adding additive automatically, the ignition temperature of the soot is
lowered. The additive is in a separate deposit and, after settling, is pumped
to the interior of the fuel tank The additive is also burned in the filter with the
soot, and so is not released into the atmosphere.
WARNING
The particle filter attains very high temperatures. Fire hazard!
•Never park where the catalytic converter could come into contact with
dry grass or inflammable 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, because the heat from the engine could ignite them.
WARNING
The additive is toxic.
•If any work is required on the additive deposit, go to a specialized work-
shop because of the danger of toxicity.
•The additive should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
Caution
•Vehicles with the diesel particle filter should not use RME fuel (biodiesel)
as it may damage the fuel system.
•Using diesel fuel with a high sulphur count can reduce the working life of
the filter. Your SEAT dealership will be able to tell you which countries have
diesel with a high sulphur content.

Electronic Stabilisation Program
Do not switch off the ESP when towing a trailer. The ESP makes it easier to
stabilise if the trailer starts to snake.
Driving economically and with respect for the
environment
General notes
Fuel consumption depends largely on your personal driving
style.
Fuel economy, environmental impact and wear on the engine, brakes and
tyres depend largely on three factors:
•Personal driving style
•Conditions of use (weather, road surface)
•Technical requirements
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.
Think ahead when driving
A vehicle uses most fuel when accelerating. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.
Regular servicing
By taking your car to an Authorised Service Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. 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.
Check the oil level every time you fill the tank. Oil consumption depends to a
great extent on the engine load and engine speed. Depending on your
personal driving style, oil consumption can be up to 1 litre per 1,000 km.
