The warning lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes of
f 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 faults. 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.
For those vehicles fitted with ESP* the function “Recommended steering
manoeuvre” is included. See ⇒page 185.
Emission control system*


This warning lamp monito rs the exhaust system.
Warning lamp
 flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest qualified workshop to have the
engine checked.
The instrument panel displa ys the following message
16): EXHAUST GAS SEE
WORKSHOP . Warning lamp
 is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest qualified workshop to have the engine checked.
The following information text displayed in the instrument panel display :
EXHAUST GAS SEE WORKSHOP .
Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
programme.
This programme includes the ABS, EDL and TCS. This also includes the brake
assist system (BAS), automatic cleaning of the brake discs and the trailer
stability programme (TSP).
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.
•
It will light up continuously if there is a malfunction in the ESP.
•
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 func-
tional.
If the ESP button is activated, the TCS function deactivates and the warning
lamp flashes.

If 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 248, “Fuses”.
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 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 avo id high engine speeds, driving at
full throttle and over-loading th e 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 ⇒page 262, “Jump-starting”.For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle stationary.
You should drive off as soon as you star t 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
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 165, fig. 136 . The
indication lamp

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 ⇒page 262.
Glow plug system for the diesel engine
To avoid unnecessary discharging of the battery, do not use any other major
electrical equipment while th e glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 76 goes out.
Starting the engine after the fuel tank has been completely run dry
If the fuel tank has been completely ru n dry, it may take longer than normal
(up to one minute) to start the engine afte r refuelling with diesel fuel. This is
because the system must eliminate air first.

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 more than 50 metres to start
the engine. Unburnt fuel could enter th e 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 batte ry of another vehicle. Note and follow
the instructions ⇒page 262, “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.Switching the engine off– Stop the engine.
– Turn the ignition key to position ⇒page 165, fig. 136 .
After switching the engine off, the radiator fan may run on for up to 10
minutes. It is also possible that the fan turns itself on once more if the coolant
temperature increases due to the heat accumulated in the engine compart-
ment or due to its prolonged exposure to solar radiation.
WARNING
•
Never switch the engine off until the vehicle is completely stationary.
•
The brake servo works only when the engine is running. With the
engine switched off, more strength is needed to brake. As normal brake
operation cannot be performed, risk of accidents and serious injury may
exist.
•
The steering lock can be immediately blocked once the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.Caution
If the engine has been driven hard for a long period, the engine could over-
heat when it is switched off. Risk of engine damage. For this reason, you
should idle the engine for approx. 2 m inutes before you switch it off.

gear if your vehicle has automatic tr
ansmission). 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 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 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 208, “Technical modifications”.
•
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 systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not top the reservoir up ⇒page 218,
“Topping up engine oil ”. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 262.
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. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 73. 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!•
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. These materials could catch fire when the vehicle is being driven.Caution
Never fully drain the fuel tank 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 unde r some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another fuel brand.

Practical tips
Te c h n i c a l D a t a
Underbody maintenance
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
ckeck the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
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! Fire hazard.Cleaning the engine compartment
Take special care when cleaning the engine compartment.Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the car is
frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after winter.
Your Authorised Service Centre has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recommend
having this work performed by them. The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease remo
ving solutions, or if you have the engine cleaned.
On commissioning theis work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•
When working in the engine compartm ent, always observe the safety
warnings ⇒page 213.
•
Before opening the bonnet, switch the engine off, apply the parking
brake firmly and always remove the key from the ignition.
•
Allow the engine to cool before you clean the engine compartment.
•
Do not clean the vehicle underbody, wheel arches without protecting
your hands and arms. You may cut your self on sharp-edged metal parts.
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.
•
Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out on ly by a qualified workshop or a petrol
station.

−
Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel co uld enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.PetrolPetrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol, corresponding to the standard DIN EN 228 , may be
used for vehicles with catalytic conv erters (EN = “European Standard”). Fuel types are differentiated by the
octane rating, e.g: 91, 95, 98 RON (RON
= “Regulation Octane Number, unit for determining the knock resistance of
petrol”). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
The appropriate type of fuel for your vehicle is specified in your engine tech-
nical table. “Technical Data” Section
Caution
•
Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments with reference E50 or E85, which co ntain a high percentage of ethanol,
may not be used, as they will damage the fuel system.
•
Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
•
High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason, you should use good quality petrol
containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
