Exhaust system fault* B
Exhaust gas indicatorB
If the indicator B flashes it signals possible damage to the catalytic
converter caused by defective combustion. Reduce speed immediately and
go to the nearest specialized workshop to check the engine. At the same
time, a text message or the necessary operations may appear on the instru-
ment panel .
If the indicator
B lights up, a fault has developed during driving which has
affects the quality of the exhaust gas (e. g. lambda probe fault). Reduce
speed immediately and go to the nearest specialized workshop to check the
engine. At the same time, a text message or the necessary operations may
appear on the instrument panel .
Diesel particle filter indicator lamp ¬
When the indicator ¬ lights on the instrument panel it signals that the filter
is blocked by soot because of frequent short journeys. To clean the filter of
these particles, drive at a constant speed of 60 km/h for 15 minutes. Always
respect the speed limit. The most efficient way to clean the diesel particle
filter is to drive in 4th or 5th gear, at approximately 2,000 rpm Ÿ. This
causes a temperature increase sufficient to burn the soot in the filter.
If the lamp
¬ remains lit afterwards, go to a specialized workshop to
examine the problem.
While the lamp
¬ is lit (filter blockage signal) fuel consumption increases
and the engine may lose power in some cases.
At the same time, a text message or the necessary operations may appear on
the instrument panel .
WARNING
•Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. The indications suggested by the warning lights should not
lead you to disobey the highway code.
Traction control system (TCS)* 
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
The warning lamp lights up when the ignition is switched on and should turn
out after about 2 seconds.
When the TCS is operating while driving, the warning lamp flashes. If the
system is deactivated or if there is any fault in the same, the warning lamp will
remain lit.
It will also come on if a fault should occur in the ABS because the TCS oper-
ates in conjunction with the ABS. For further information see Ÿpage 181
Electronic stabilisation programme (ESP)* 
This warning lamp monitors the electronic stabilisation
program.
This program includes the ABS, EDL and TCS.
The warning lamp
 has the following functions:
•It will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.
•It flashes when the ESP is activated when driving.

3. Switch the engine off.
4. Apply the handbrake firmly.
5. On a manual gearbox engage 1st gear. On an automatic move
the selector lever to P.
6. Use the warning triangle to draw the attention of other road users
to your vehicle.
7. Always take the key with you when you leave the vehicle.
You should switch on the hazard warning lights to warn other road users, for
instance when:
•reaching the tail end of a traffic jam
•there is an emergency
•your vehicle breaks down due to a technical defect
•you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. The turn signal lights

and the button warning light  will
also flash. The hazard warning lights also work when the ignition is switched
off.
WARNING
•The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the attention
of other road users to your stationary vehicle.
•Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
•The battery will run down if the hazard warning lights are left on for a long
time - even if the ignition is switched off.
•If the hazard warning lights are not working, you must use an alternative
method of drawing attention to your vehicle. This method must comply with
traffic legislation.
•The use of the hazard warning lights described here is subject to the rele-
vant statutory requirements.
Turn signal and main beam headlight lever
The turn signal and main beam lever also operates the
parking lights and the headlight flasher.

Starting and stopping the engine
Starting a petrol engine
The engine can only be started using a genuine SEAT key with
the correct code.
– Place the gear in neutral (if it is an automatic gearbox, place the
gear lever in P or in N).
– In vehicles with a manual gearbox, 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 position Ÿpage 161, fig. 126 to start
the engine.
– 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.
You may need to press the accelerator briefly after starting a very hot 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 lifters. 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.
WARNING
•Never start or run the engine in unventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless poisonous gas. Risk of fatal accidents. Carbon monoxide can cause people
to lose 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 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. Observe the warnings in the
chapter Help with Ignition.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This helps the engine reach oper-
ating temperature faster and reduces emissions.
Starting a diesel engine
The engine can only be started using a genuine SEAT key with
the correct code.
– Place the gear in neutral (if it is an automatic gearbox, place the
gear lever in P or in N).

WARNING (continued)

Driving 164
– In vehicles with a manual gearbox, 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 position Ÿpage 161, fig. 126 . The
warning lamp
D lights up to show that the glow plugs are
preheating the engine.
– 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 lifters. This is
quite normal, and no cause for concern.
If you have problems starting the engine, please refer to Help with Ignition.
Glow plug system
To avoid unnecessary loads on the battery, do not use any other major elec-
trical equipment while the glow plugs are preheating.
Start the engine as soon as the glow plug warning lamp goes out.
Starting a diesel 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 a diesel engine after refuelling. This is because air
needs to be bled from the fuel system while starting.
WARNING
•Never start or run the engine in unventilated or closed rooms. The
exhaust fumes contain carbon monoxide, an odourless and colourless poisonous gas. Risk of fatal accidents. Carbon monoxide can cause people
to lose 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 for more than approximately

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

•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.
WARNING (continued)

Driving and the environment 188
Driving abroad
Notes
For driving abroad, the following must be taken into consideration:
•For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chapter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.
•In some countries it is possible that a vehicle model is sold under condi-
tions where some spare parts are not available or that the Authorised Service
Centre may only carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparation of your vehicle in addition to necessary maintenance
and repair possibilities.
Adhesive strips for headlights
If you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available from your Authorised Service
Centre.
Trailer towing
What do you need to bear in mind when towing a trailer?
The vehicle can, if suitably equipped, be used to tow a trailer or caravan.
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. If you wish to retrofit a towing bracket Ÿpage 204.
Connectors
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 SEAT Service
Trailer weight / draw bar loading
Never exceed the maximum permitted trailer weights. If you do not load the
trailer up to the maximum permitted trailer weight, you can then climb corre-
spondingly 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). 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 given on the data plate
of the towing bracket are for certification purposes only. The correct figures
for your specific model, which may be lower than these figures for the towing
bracket, are given in the registration documents and “Technical data”.

Driving and the environment 192
Avoid short journeys
The engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.
Directly after a cold start, the engine uses about 50-70 litres of fuel per
100 km. This figure then drops to 20-30 litres per 100 km after about one
kilometre. The engine only reaches its working temperature after about four
kilometres, when fuel consumption will return to a normal level. You should
therefore avoid short journeys.
The ambient temperature has a decisive influence.
The illustration shows the different rates of fuel consumption for the same
distance at both +20°C and -10°C. Your vehicle will use more fuel in winter
than in summer.

tion in litres per 100 km at

Cleaning and caring for your vehicle 198
WARNING
•Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.
•Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle. “Dry” the brakes by applying the brakes carefully several
times
Cleaning alloy wheels
Every two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheels.
Every three months
– Apply a hard wax compound to the wheels.
Alloy wheels require regular attention to preserve their appearance. It is
important to remove road salt and brake dust by washing the wheels at
regular intervals, otherwise the finish will be impaired.
Always use an acid-free detergent for alloy wheels.
Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by stone impact, the damaged area should be
repaired immediately.
WARNING
•Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.
•Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle. “Dry ” the brakes by applying the brakes carefully several
times
Underbody sealant
The underside of the vehicle is coated to protect it from corro-
sion and damage.
The protective coating could be damaged when driving. We recommend that
the protective coating under the body and on the running gear should be
checked, and reinstated if necessary, before and after the winter season.
We recommend that repair work and additional anti-corrosion work is carried
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! This is a fire
hazard.

Checking and refilling levels 206
Checking and refilling levels
Refilling
The tank filler neck is located at the rear right-hand side of the vehicle.
The tank flap is locked and unlocked automatically by the central locking
system.
The fuel tank holds about 70 litres.
The tank cap can, once unscrewed, be hung on the tank flap Ÿfig. 138.
After filling up, screw the tank cap back in firmly and close the tank flap until
it engages.
WARNING
All legal stipulations must be observed when transporting a reserve
supply. For safety reasons, we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident and
leak.
Caution
•Never run the fuel tank empty on vehicles equipped with a catalytic
converter. An irregular fuel supply could cause misfiring. In this way the fuel
can arrive without burning the exhaust system, which could cause the cata-
lyser to overheat resulting in damage.
•Spilt fuel should be removed from the vehicle paint finish as quickly as
possible as the paint could otherwise be damaged. Especially if biodiesel
fuel is being used Ÿpage 207.
For the sake of the environment
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are
warm.
