Time
The time is also displayed when the ignition is switched off. The clock can be
set with the right-hand rotating button below the rev counter “digital clock”.
min - Journey duration
The display shows the amount of time that has elapsed since the ignition was
switched on.
The maximum display value in both me mories is 99 hours and 59 minutes.
The memory will automatically be deleted once this value has been reached.
Ø mph - 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.
Miles - Distance travelled
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.
 Miles - Fuel range
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 litre/100km - Average fuel consumption
The average fuel consumption will be shown ⇒page 54, fig. 37 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 amount of fuel used will not be shown.
litres/100km or litres/hr - 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 158.
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 10 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!

•
If the function is not deactivated by pressing the button, this will be deac-
tivated after about 20 mins.
Economic use of the air conditioningWhen the air conditioning is switched on, the compressor consumes engine
power and has an effect on fuel consumption. Observe the following points
in order to have the equipment operating for a short a time as possible.
•
If the vehicle interior has overheated due to excessive solar radiation, it is
best to open the windows or doors to allow the hot air to escape.
•
When travelling, the air conditioning should not be switched on if the
windows or sun roof are open.*
ClimatronicControl switchesThe air conditioning system only works when the engine is running and the blower is switched on.

Driving and the environment
158Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will pr event the jerking that can be
caused by the trailer wheels locking. Select a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle.
Heating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always monitor the temperature indicator for the
coolant ⇒page 49.
Electronic Stabilisation program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.
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 style 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 accelerating. 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 Service 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 180. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving s tyle, oil con s
umption 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. 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

Checking and refilling levels
174
− 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 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 recommended for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
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.
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 173.RME fuel*The biodiesel fuel must comply wit h 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 Ester”.
Your Authorised Service Centre or au tomobile 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 that 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 biodiesel fuel 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.
•
If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation. For
this reason, “winter-grade diesel fuel” is available in some countries during
the cold months. It can be used at temperatures as low as -22°C.

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 inflation 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 sticker.
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.
Tyre service life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.

Checking and refilling levels
194Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ page 193, fig. 134 running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the letters “TWI” or other symbols) indicate the
positions of the tread wear indicators. The minimum tread depth required by
law is 1.6 mm (measured in the tread grooves next to the tread wear indica-
tors). Worn tyres must be replaced. D ifferent figures may apply in export
countries ⇒.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-out.
For this reason, the tyre pressure should be checked at least once per month
⇒ page 193.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to change them around as shown ⇒page 193, fig. 135. All the tyres will then
last for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyre s. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessiv e tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
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 knowledge of tyre designations makes it
