– 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.

Glow plug system for the diesel engine
To avoid unnecessary load on the battery, do not use any other major elec-
trical equipment while the
glow plugs are pre-heating.
Start the engine as soon as the glow plug warning lamp ⇒page 81 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 af ter refuelling with diesel fuel. This is
because the system must eliminate air first.
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 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.Switching off the engine– Stopping the engine.
– Turn the ignition key to position ⇒page 154, fig. 116 .After the engine is switched off the radiator fan may run on for up to 10
minutes, even if the ignition is switched of f. It is also possible that it will turn
itself on once more if the temperature of the coolant increases due to the
elimination of built up heat in the engine compartment or if this is heated due
to prolonged exposure to the heat of the sun.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo works only when the engine is running. You will need
more strength to brake the vehicle when the engine is switched off. As you
cannot brake in the normal manner, there is a greater risk of accidents and
serious injury.
•
The steering lock can engage immediately when the key is removed
from the ignition lock. The vehicle cannot be steered. Risk of accident.

Driving and the environment
178Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive faster than three quarters of top speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal friction in the engine is
greater than later on when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gently, the life of the engine will be increased and its oil
consumption reduced.
Running in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compen sate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads which have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may cause an accident. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run in” and do not have the correct friction
properties during the first 200 km. Ho wever, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
Exhaust gasses purification systemCatalytic 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
⇒page 210, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 255.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 72. 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 driven.Caution
Never fully drain the fuel tank, in this case, the irregularity of the fuel supply
may cause ignition problems. This allow s 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 reme-
died by changing to another brand of fuel.
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine dust filter eliminates most of the soot from the exhaust gas
system. Under normal driving conditions, the filter cleans itself. If the driving
conditions do not allow the filter to clean itself (for example, multiple short
trips) the filter will be obstructed by dust and pollen and the indicator for the
diesel engine particulate filter indicator will light ⇒page 79.
WARNING
•
The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.Caution
Vehicles equipped with a diesel engine particulate filter must not be refueled
using biodiesel (RME), given that the fuel system may be damaged.Driving abroadNotesFor 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 chap ter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.

Cleaning and caring for your vehicle
196Underbody 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 addi tional anti-corrosion work is carried
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corros ion coatings to the exhaust pipes,
catalytic converter or the heat shield s on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! This is a 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 particularl y 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 the salting period.
Your Authorised Service Centre is able to provide the correct cleaning and
preserving products and has the necessary equipment. 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 removing solutions, or if you have the engine cleaned.
If this job is carried out, you should ensure that all surfaces, seams, joints and
components in the engine compartmen
t are given anti-corrosion treatment
afterwards.
WARNING
•
When working in the engine compartment, always observe the safety
wa rnin
gs ⇒ page 204.•
Switch off the engine, apply the parking brake firmly and always
remove the key from the ignition before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
•
Do not clean the underside of vehicle, 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. If possible, avoid sudden braking immediately after washing
the vehicle.
•
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 only by a qualified workshop or a suit-
able filling station.

Checking and refilling levels
202
− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.
− 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 could 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 converters (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. If, in exceptional circumstances, the correct
octane rating is not available:•
For engines which require Premium unleaded petrol (95 RON) the
following is valid: Regula r unleaded fuel with 91 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
•
For engines which require Premium unleaded petrol (98 RON) the
following is valid: Premium unleaded fuel with 95 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
– If premium unleaded petrol is not available, the engine can be run on
regular unleaded petrol with 91 RON as an “emergency measure”. In this
case only use moderate engine speeds and a light throttle. Avoid using full
throttle. Fill up with premium petrol as soon as possible.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 contain a high percentage of ethanol,
may not be used, as they will damage the fuel system.

Tips and Maintenance
Te c h n i c a l D a t a
•
Even one tankfull of leaded fuel would permanently impair the efficiency
of the catalytic converter.
•
High engine speed and f ull throttle can damage the engine when using
petrol with an octane rating lower th an 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.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 201.
RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply wi th the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for “ Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation “ Fatty Acid Methyl E ster”.
If the date sticker of the vehicle in cludes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•
The performance of a vehicle using biodiesel maybe somewhat reduced.
•
Fuel consumption of a vehicle using biodiesel may be slightly higher.
•
RME fuel can be used in winter at temperatures down to approx. -10°C.
•
At outside temperatures below -10°C, we recommend using winter diesel
fuel.Caution
•
RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.
