Driving
Starting and stopping the engine Starting petrol engines
The engine can only be started using a genuine SEAT key
with its correct code.
– Move the gearbox lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the start-
er to turn the engine on.
– Turn the ignition key to the starting ⇒ page 145 position.
– Let go of the ignition key as soon as the engine starts; the start-
er motor must not run on with the engine.
After starting a very hot engine, you may need to slightly press down the ac-
celerator.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds 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 the starter off after 10 sec-
onds and try again after half a minute. If the engine still does not start, the
fuel pump fuse should be checked ⇒ page 231, Fuses.
WARNING
● Never start or run the engine in unventilated or closed rooms. The ex-
haust gases contain carbon monoxide, an odourless and colourless poi-
sonous gas. Risk of fatal accidents. Carbon monoxide can cause loss of
consciousness. It can also result in 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 avoid high engine speeds, driving
at full throttle and over-loading the engine. Risk of engine damage.
● The vehicle should not be pushed or towed more than 50 metres to start
the engine. Unburnt fuel could enter the catalytic converter and damage it.
● Before attempting to push-start or tow a vehicle in order to start it, you
should first try to start it using the battery of another vehicle. Note and fol-
low the instructions in ⇒ page 248, Jump-starting.
For the sake of the environment
Do not warm-up the engine by running the engine with the vehicle station-
ary. Start off immediately, driving gently. This helps the engine reach oper-
ating temperature faster and reduces emissions. 

Refuelling with LPG
The LPG filler neck is behind the fuel cap, next to the petrol
filler neck.

Refuelling with LPG
– Before refuelling, stop the engine and switch off the ignition.
– Open the tank flap.
– Before refuelling, please read the instructions on the pump.
– Unscrew the cap of the gas filler neck ⇒ Fig. 128 1
.
– Screw the required adapter ⇒ Fig. 128 2
on the gas filler neck
1.
– Refuel as indicated in the instructions on the pump.
– Unscrew the adapter ⇒ Fig. 128 2
.
– Screw on the cap of the gas filler neck ⇒ Fig. 128 1
.
– Close the tank flap.
When the hose is removed from the tank, a small amount of LPG may spill
out ⇒

Checking and refilling levels
The LPG tank ⇒ Fig. 129 in the spare wheel well has a capacity of 52.8 li-
tres. If the outside temperatures are very low, it may not be possible to com-
pletely fill the LPG tank.
Pump attachments
There are a variety of types of LPG pump, and the methods of use may vary.
Therefore, let the pump operator fill the tank when refuelling for the first
time or fill from another pump.
Noises when refuelling with LPG
When refuelling with LPG, noises may be heard. These noises are insignifi-
cant.
WARNING
Failure to refuel or handle LPG in the correct way could result in a fire,
cause an explosion or lead to injuries.
● LPG is a highly explosive and inflammable substance. It may cause
severe burns and other injury.
● Switch off the engine before refuelling.
● Always switch off mobile phones and any other radiophony applian-
ces, as electromagnetic waves may produce sparks and cause a fire.
● Do not remain in the vehicle while refuelling. If it is absolutely neces-
sary to enter the vehicle, close the door and touch a metal surface before
touching the attachment again. This will prevent the generation of static
electricity and any possible fires while refuelling.
● Small quantities of LPG may leak out after refuelling. If LPG comes in-
to contact with skin, there is a risk of freezing.
● Do not smoke and always keep bare flames away from the tank during
refuelling. Failure to do so may lead to an explosion.
 Adapter for the liquid petroleum gas (LPG) filler neck
An adapter is required due to the existence of a range of
pumps with different nozzles.
Fig. 130 General table of LPG filler neck adapters.
ACME adapter (adapter for Europe)
Dish Coupling Adapter (adapter for Italy)
Bayonet adapter
EURO adapter (adapter for Spain)
The supply includes the adapter for the country in question, the ACME 1
,
the Dish Coupling 2, the bayonet 3 or the EURO adapter 4.
The filler systems and corresponding adapters vary according to country. As
petrol stations abroad do not always have the necessary adapters for your
LPG system, we recommend you purchase the appropriate adapter before
travelling abroad. Check that the adapters are suited to your filling system. 

Note
The four most common types of adapter in Europe are the ACME adapter 1,
the Dish Coupling adapter 2, the bayonet adapter 3 and the EURO adapt-
er 4. On the whole, we recommend you carry all four adapters in your vehi-
cle, as some countries use more than one type of filling system. The intro-
duction of a single system (Euronozzle) throughout Europe is being studied. 
LPG fuel
LPG is an alternative vehicle fuel and is a blend of propane and butane.
The success of LPG is due to the strict regulations concerning exhaust gas
emissions. Compared to other fossil fuels, LPG is characterised by its re-
duced emissions.
LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe.
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter
gas may be lower (due to increased consumption) than that of summer gas.
LPG supplier network
The number of LPG pumps is constantly increasing.
Lists of existing LPG pumps may be found on Internet. 
LPG safety
A series of collision tests performed on this vehicle while running with LPG
have confirmed its high level of safety. The safety of the LPG system guarantees operation without risk. The follow-
ing safety measures have been adopted:
●
The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.
● A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.
● A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.
● All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ 
. These checks are included in the Maintenance
Programme.
WARNING
● If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle.
Do not carry on driving! Take the vehicle to a specialised workshop and
have the fault repaired.
● Immediately extinguish any cigarettes and remove from the vehicle
any objects which might produce a spark or cause a fire, and switch off
immediately if gas is smelt or a leak is detected.
● LPG tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed cor-
rectly.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
For any fault in the LPG system, please refer to the SEAT web page, which
lists the workshops authorised to repair these faults. 
