Set speed indicator
When driving at the required speed, enter the speed indicator mode and
press the button
A (Reset), the display remembers the indicated speed. If the
indicated speed is exceeded, a warning text is displayed on the screen
5) and
a warning signal sounds.
This may be deactivated by pressing the button A (Reset).
The speed may be altered using the rocker switch B in steps of 5 km/h within
5 seconds of the initial memory value.
Ø km/h - Average speed
The average speed will be shown after a distance of approximately 100
metres has been travelled. Dashes will appear in the display until that time.
The display will be updated every 5 seconds whilst the vehicle is in motion.
km - Distance covered
The display shows the distance travelled since the ignition was switched on.
The maximum display value in both memories is 9999 miles. The memory will
automatically be deleted once this value has been reached.
 km - Distance to empty
The fuel range is calculated using the fi gures for tank content and current fuel
consumption. It shows how far the vehicle can travel using the same condi-
tions as a reference.
Ø ltr/100km - Average fuel consumption
The average fuel consumption will be shown ⇒page 62, fig. 41 after a
distance of approximately 100 metres has been travelled. Dashes will appear
in the display until that time. The display will be updated every 5 seconds
whilst the vehicle is in motion. The am ount of fuel used will not be shown. litres/100km or litres/h - Current fuel consumption
The display will show the current fuel consumption in litre/km whilst the
vehicle is in motion or in litre/hour when
the vehicle is in a stationary position
with the engine running.
Using this display you can see how your driving style affects fuel consump-
tion ⇒page 175.
Ambient temperature display
The measurement margin extends from -45° C to +58° C. At temperatures
lower than +4° C, an “ice crystal symbol” is displayed and a “warning”
sounds if the vehicle is moving at more than 20 km/h (ice warning). This
symbol will flash for about 10 seconds and remains lit until the exterior
temperature rises above +4° C or 6° C if it was already lit.
WARNING
There could be black ice on the road surface even if the “snowflake symbol”
is not shown. You should, for this reason, not rely exclusively on this
display - Risk of accident!
Note
When the vehicle is stationary or travelling at very low speeds, the tempera-
ture displayed may be slightly higher than the actual ambient temperature as
a result of the heat radiated from the engine.Warning or information text in the display
Faults are shown in the display with warning lamps and
warning/information reports.The system runs a check on certain components and functions when the igni-

Tips and Maintenance
Te c h n i c a l D a t a
Driving economically and with respect for the
environmentGeneral 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 styl e 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 drivingA vehicle uses most fuel when accelera ting. 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 servicingBy taking your car to an Authorised Se rvice 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 ⇒page 198. 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.Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.

tion in litres per 100 km at

Driving and the environment
176Directly 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 rate s 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.

Tips and Maintenance
Te c h n i c a l D a t a
−
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 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 converters (EN = “European Norm”).
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 RON (RON = “research octane number” ). You may use petrol with a higher
octane number than the one recommende d for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
Even one full tank 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

192containing 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 190.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 with the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
• DIN is a German abbrev iation for “Deuts che
s In s
titut für Normug e.V .”, the
German standards institute.
•
EN means E uropean Norm.
• FAME is the English abbrev iation “Fatty Acid
Methy l Este r” If the date sticker of the vehicle includes 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 maybe 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.
•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.

210New tyres
New tyres have to be run in ⇒page 169.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•
New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may cause an accident.
•
If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflatio n pressure from the sticker. The
values refer to Summer tyres. For Winter tyres, you must add
0.2 bar to the values given on the sticke r.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!•
At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
•
If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.

WARNING
There is a serious danger of accidents if a tyre bursts during driving!•
The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning”.
•
At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
•
If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•
Keep chemicals such as oil, fuel and brake fluid away from tyres.
•
Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essenti al part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A kn owledge of tyre designations makes it easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
195 Tyre width in mm
65 Height/width ratio in %
R Tyre construction: Radial
15 Rim diameter in inches
91 Load rating code
T Speed rating
The tyres could also have the following information:
•
A direction of rotation symbol
•
“Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicate d on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT ... 1103 ...” means, for example, that the tyre was produced in the 11th
week of 2003.
We recommend that work on tyres and wheels is carried out by an Authorised
Service Centre. They are familiar with the procedure and have the necessary
special tools and spare parts as well as the proper facilities for disposing of
the old tyres.
Any Authorised Service Centre has full information on the technical require-
ments when installing or changing tyres, wheels or wheel trims.
WARNING
•
We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
