The fuel tank has a capacity of approx. 55 litres.
When the needle reaches the reserve area ⇒ fig. 33 (arrow), the warning
lamp will light up and an acoustic signal will sound reminding the driver to
refuel. At this point there are still 7 litres of fuel in the tank.
The following text appears on the instrument panel display 1)

⇒ fig. 34.
Needle in normal zone B
In normal driving conditions, the needle should be in the middle section of
the scale. The temperature may also rise when the engine is working hard,
especially at high outside temperatures. This is no cause for concern as
long as the warning lamp does not light up and no warning message* ap-
pears on the instrument panel display.

LPG system filler level display
The LPG tank ⇒ 
in the spare wheel well has a capacity of 39 litres at an
outside temperature of 15°C ⇒ page 212, Refuelling with LPG.
The charge level can be checked on the analogue gas gauge located on the
instrument panel ⇒ fig. 35. When the level reaches reserve, a notification
text is displayed on the screen. Refill with LPG at the earliest opportunity.
If, while driving in LPG mode, a sudden warning signal is heard and the
warning LPG fault, contact workshop is displayed on the screen1)
, it means
that there is a fault in the LPG system. Take the vehicle to a specialised
workshop to check the LPG system.
WARNING
LPG is a highly explosive and inflammable substance. It may cause se-
vere burns and other injury.
● Due care must be taken to avoid any risk of fire or explosion.
● 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
● The values shown in the average fuel consumption and distance to emp-
ty indications on the multifunction display (MFI) 2)
on the instrument panel 1)
are approximate values only.
● Two different consumption values are given on the MFI, depending on
whether the vehicle is running in GAS or Petrol mode.
● Please check the fuel level on the fuel level gauge on the instrument
panel ⇒ page 58
● If frequent short journeys are made, especially when the outside tem-
perature is low, the vehicle will tend to run on petrol more often than on
LPG. Therefore, the petrol tank may empty before the LPG tank. 

190Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 208, Technical modifi-
cations.
● If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessa-
ry journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 222, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 263.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

210Checking and refilling levels
Checking and refilling levels
Refuelling
The fuel cap cover opens automatically with the central lock-
ing system. The tank holds approximately 55 litres.
Fig. 138 Tank flap open
Unscrewing the tank cap
– Lift the lid.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a
“click”.
– Close the drawer. Make sure you hear it click into place. The
tank cap is secured with an anti-loss attachment The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are
warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of
the fuel tank flap. Here you will find further information on fuel.
Releasing the fuel tank flap manually
If the central locking system fails, the fuel tank flap can be opened manually
as follows:
●
Open the tailgate
● Remove the cover from the right side trim in the luggage compartment.
● Insert a hand and pull the locking device back
● Open the cap and take out the plug. 

Checking and refilling levels
– Screw on the cap of the gas filler neck 1
.
– Close the tank flap.
When the hose is removed from the tank, a small amount of LPG may spill
out ⇒ 
.
The LPG tank ⇒ fig. 140 in the spare wheel well has a capacity of 39 litres. If
the outside temperatures are very low, it may not be possible to completely
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 disconnect 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.
WARNING (Continued)
● 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.

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 products) with diesel fuel. 
Working in the engine compartment Safety 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 lever 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 219. You should not do any work in the engine compartment unless you know ex-
actly how to carry out the jobs and have the correct tools! Have the work car-
ried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs
and batteries, are under constant development. SEAT provides a constant
flow of information to the Authorised Service Centres concerning modifica-
tions. For this reason, we recommend you to have service fluids and con-
sumables replaced by an Authorised Service Centre. Please observe the rel-
evant instructions
⇒ page 208. The engine compartment of the vehicle is a
hazardous area ⇒ 
.
WARNING
