The glow plug lamp does not come on – the engine can be started
straight away.
K
Starting after running out of fuel
If the tank on vehicles with a diesel engine was empty, starting
after filling with diesel fuel can take longer than normal – up to
one minute. This is because the fuel system must first be freed of
air before starting.

When the engine has been subjected to a heavy engine load for a long
time, the engine must not be switched off abruptly. Let it idle for about 2
minutes to avoid overheating.

Do not switch off the ignition while the vehicle is in motion with a gear
engaged; otherwise unburned fuel may go into the converter, where it
would burn and cause overheating, which would damage the converter.

On vehicles with a catalytic converter, never drive until the fueltank is
completely empty. The irregular fuel supply can cause misfiring. This allows
unburnt fuel into the exhaust system, which can cause overheating and
damage to the catalyst.

Releasing tank flap manually
If the central locking system should fail, the flap can be released
manually:
• Open tailgate and – if fitted – fold back the right luggage
compartment trim from side panel.
• Then push the locking rod in front of the white diaphragm
housing backward slightly in direction of arrow
⇒fig. 150.K

In the chapter “Technical Data” and on the inside of the tank flap
you will find information on the correct octane rating for your
engine.

General notes
•Unleaded petrol must comply with DIN EN1)228 and leaded
petrol with DIN 51 600.
•If, in an emergency, the octane rating of the available petrol is
lower than that required by the engine, only drive with medium
engine speeds and low engine loading. H Hi

•Fuel with a higher octane rating than that required by the engine
can be used without limitation. There are, however, no advantages
regarding output and consumption.

After the running-in period
•On vehicles with a rev counter* the maximum permissible engine
speed is shown by the beginning of the red zone on the rev
counter scale. The needle of the counter must not move into this
zone.
Extremely high engine revs will be automatically governed.

is of great importance for the environment-friendly functioning of
your vehicle.
Therefore, keep in mind the following points:
•Versions with a catalytic converter must only use unleaded fuel
⇒"Filling the tank" chapter.
•In vehicles with a catalytic converter never drive until the fuel
tank is completely empty. Irregular fuel supply can cause misfiring,
thus allowing unburned fuel into the exhaust system which can
cause overheating and damage to the catalyst.
•If you experience starting difficulties, loss of power or engine
problems while driving, the cause could be a failure in the ignition.In this case, fuel may be entering the exhaust system without
burning and, in this way being released into the atmosphere.
Furthermore, the catalyst could deteriorate due to overheating.
Reduce speed immediately. Have this problem fixed at the nearest
Technical Service Centre.
•Do not overload the engine with oil
⇒"Engine oil" chapter.
•Do not towstartthe vehicle for more than 50 m
⇒"Tow
start/towing" chapter.
N No

Even when the cleaning system for exhaust fumes is in perfect working
order, under certain circumstances, the fumes may smell like sulfur.
This depends on the percentage of sulfur in the fuel.
Often it is sufficient to change brands or buy super unleaded.

Safety FirstControls and equipment Tips and Maintenance Technical Data
Suggestion 6. Avoid short drives
The engine and the catalytic converter must
reach its optimum functioning temperature in order to effectively
reduce consumption and toxic gas emissions.
The fuel consumption of a cold engine of a normal vehicle right
after the start is about 30-40 liters per 100 km. After about one
kilometer the consumption decreases to 20 liters. After about
f fo
ou
ur
r
kilometers the engine has warmed up and the consumption is
normal. For this reason, it is important to avoid short drives and
heating the vehicle’s engine when the vehicle is not moving. Drive
on quickly!
The ambient temperature also counts. The illustration shows the
difference in consumption (l/100km) for the same distance (km) at
+20°C and –10°C. Your vehicle’s consumption is higher in the
summer than in the winter
⇒fig. 153.K
Suggestion 7. Check the tyre pressure
Make sure that the tyres have always adequate pressure. Even half
a bar less increases the level of fuel consumption by 5 percent. If
the pressure is not correct, the tyres wear out faster due to an
excessive deformation and overheating which, in turn, will
decrease the driving performance.
Always check the tyre pressure when the tyre is cold.
In addition, do not drive year round with winter tyres. They make
more noise and increase fuel consumption by 10 percent. Change
to summer tyres on time.
K
Suggestion 8. Avoid unnecessary weight
Apart from driving habits and periodic revisions of your vehicle,
there are other ways to reduce fuel consumption:

Every kilogram increases fuel consumption. For this reason, it is
worth checking your boot to avoid unnecessary weight.
Frequently, the roof rack will stay on the roof even though it is no
longer needed. Due to greater air resistance, an unloaded roof
rack at a speed of 100-120 km/h increases the consumption by
approx. 12%.

Observations
If the vehicle is to be taken abroad, the following must also be
borne in mind:
• If the vehicle has a petrol engine and catalytic converter, one
must ensure that unleaded petrol will be available during the
journey
⇒"Filling the tank" chapter. The automobile clubs offer
information about the unleaded filling station network.
•In some countries it is possible that a vehicle model is sold under
conditions where some spare parts are not available or that the
Technical Services 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.
K
Headlight covering
When traveling abroad in a country where driving is on the
opposite side to the home country, asymmetric headlights will
dazzle oncoming traffic.
To prevent this, headlights must be adjusted or some areas must
be covered with an opaque adhesive strip depending on the
model. For more information, contact your Technical Service
Centre.
K

182Care and maintenance
If the engine compartment is cleaned at any time with grease
removing solutions1)or if one has the engine washed, the anti-
corrosion compound is nearly always removed as well. It is
therefore essential to ask for durable preservation of all surfaces,
seams, joints and components in the engine compartment to be
carried out. This applies also when corrosion protected parts are
renewed.

Because when washing the engine petrol, grease and oil deposits are
washed off, the dirty water must be cleaned by an oil separator. For this
reason engine washing should only be carried out in a workshop or filling
station.
K
Undercoating
The underside of the vehicle is coated with a special compound to
protect it from corrosion and damage.
However, as this protective layer becomes damaged when the
vehicle is in use, the protective coating under the body and on the
running gear should be examined at defined intervals – preferably
before and after the winter season – and any damage made good.N No

Due to the high temperatures which occur in the afterburning
process, additional heat shields are fitted over the catalytic
converter. Underbody sealant must not be applied to these
shields, the catalytic converter or the exhaust pipes. Removal of
the heat shields is also not permissible.
K
Cavity preservation
All cavities on the vehicle which could be susceptible to corrosion
are given permanent protection at the factory.
This coating does not need checking or any subsequent treatment.
Should a small amount of wax run out of the cavities at high
ambient temperatures it can be removed with a plastic scraper and
some white spirit.
