can set the temperature, air distribution and the fan speed.
– To switch a function on or off, press the appropriate button   or  . When the function is activated, the display window in the 
lower left of the button is lit.Temperature
With the regulator   the heating level is determined. The required tempera-
ture inside the vehicle cannot be lower than the ambient temperature.  Maximum heat output, which is needed to defrost the windows quickly, is 
only available when the engine has reached its operating temperature.

20 minutes 
after being switched on. It can also be  switched off beforehand by pushing

during this initial warm-up phase. It is therefore best to drive off immediately 
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees 
that, before beginning a journey, you 
will not waste fuel. 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.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and 
the exhaust filtration systems should reach the optimum  service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine 
does not warm up and fuel consumption does not regularise until having 
driven some  four kilometres. This is the reason why we recommend avoiding 
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping  the tyres at an adequate pressure saves fuel. If the 
tyre pressures are just 1 bar too low, this can put the fuel consumption up by 
as much as 5%. Due to the greater roll ing resistance, under-inflation also 
increases  tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are  cold.
Do not use  winter tyres  all through the year: they will increase fuel consump-
tion by up to 10%.
Avoid unnecessary weight
Every kilo of  extra weight  will put up the fuel consumption, so it is worth 
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is 
no longer needed. At a speed of 100-120 km/h your car will use about 12%  more fuel as a result of the extra wind resistance caused by the roof carrier 
even when it is empty.
Save electrical energy
The engine activates the alternator, whic
h produces electricity. With the need 
for electricity, fuel consumption is also increased. Because of this, always 
turn off electrical equipme nt when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window 
heating or the seat heaters*.

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. 
Therefore, “winter-grade diesel fuel” is available in some countries during 
the cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel generally sold 
has different temperature characteristics. Check with an Authorised Service 
Centre or filling stations in the country concerned regarding the type of diesel 
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for 
operation in winter. This ensures that the fuel system remains operational to 
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start 
at temperatures of under -24°C, simply place the vehicle in a warm place for 
a while.
Caution
Do not mix fuel additives (“thinners”,  or similar additives) with diesel fuel.
Working in the engine compartmentSafety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the 
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1.  Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3.  Move the gear stick to neutral or the selector lever to position  P.
4.  Wait for the engine to cool down.
5.  Keep children away from the vehicle.
6.  Raise the bonnet  ⇒page 215.You should not do any work in the engine compartment unless you know 
exactly how to carry out the jobs and have the correct tools! Have the work 
carried out by a qualified workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and 
batteries, are being constantly developed. SEAT provides a constant flow of 
information to the Authorised Service  Centres concerning modifications. For 
this reason, we recommend you to have service fluids and consumables 
replaced by an Authorised Service Centre. Please observe the relevant 
instructions  ⇒page 208. The engine compartment of any motor vehicle is a 
hazardous area ⇒ .

220•
Never pour oil down drains or into the ground.
•
Use a suitable container when draining the used oil. It has to be large 
enough to hold all the engine oil
CoolantCoolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive.The cooling system must be filled with a mixture of water and at least 40 % of 
our coolant additive G 12+ or an addi tive with the specification TT-VW 774 F 
(it is dyed purple). This mixture gives the necessary frost protection down to 
-25
° C and protects the alloy parts of the cooling system against corrosion. It 
also prevents scaling and raises the boiling point of the coolant.
The concentration of coolant must  always be at least 40% - even if frost 
protection is not required.
If greater frost protection is required in very cold climates, the proportion of 
the antifreeze additive G 12+ can be increased. However, the percentage of 
coolant additives should not exceed 60%, as this would reduce the frost 
protection. It would also reduce th e cooling effect. A mixture with 60% 
coolant additive will give frost protection to approx. -40
° C.
WARNING
•
The coolant additive is toxic. There is a toxic risk. Always keep the 
coolant additive in the original container which should be stored out of the 
reach of children. The same applies to coolant which you have drained off.
•
The coolant additive G 12+ must be  added in sufficient quantities to 
provide anti-freeze protection at the coldest ambient temperatures that 
can be expected. At extremely cold ambient temperatures, the coolant 
could freeze, causing the vehicle to breakdown. As the heater would also 
not work in this situation, there is a risk of suffering exposure!Caution
•
Other additives may give considerably inferior corrosion protection. The 
resulting corrosion in the cooling syst em can lead to a loss of coolant, 
causing serious damage to the engine.
•
The coolant additive G 12+ (purple) can be mixed with the additive G 12 
(red) or  G 11. Never mix G12 (red colour) with G 11.WARNING (continued)

How to jump start: description⇒fig. 199    shows the flat battery and   the charged battery.
Jump lead terminal connections
– Switch off the ignition on both vehicles  ⇒.
1.  Connect one end of the red jump lead to the positive  ⇒fig. 199 
 terminal of the vehicle with the flat battery  ⇒.
2.  Connect the other end of the red jump lead to the positive  terminal   in the vehicle providing assistance.
3.  Connect one end of the black jump lead to the negative terminal   on the battery of the vehicle providing assistance. 4.  Connect the other end of the black jump lead   to a solid metal 
component which is bolted on to the engine block, or onto the 
engine block itself of the vehicle with the flat battery. Do not 
connect it to a point near the battery  ⇒.
5.  Position the leads in such a way that they cannot come into  contact with any moving parts in the engine compartment.
Starting
6.  Start the engine of the vehicle  with the boosting battery and let 
it run at idling speed.
7.  Start the engine of the car with the flat battery and wait one or  two minutes until the engine is “running”.
Removing the jump leads
8.  Before you remove the jump leads, switch off the headlights (if  they are switched on).
9.  Turn on the heater blower and rear window heater in the vehicle  with the flat battery. This helps minimise voltage peaks which are 
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse  order to the details given above.
Connect the battery clamps so they ha ve good metal-to-metal contact with 
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and 
try again after about half a minute.
