The engine management automatically adapts to the natural gas used ac-
cording to its quality. Therefore, different quality gases can be mixed in the
tank, without the need for comprehensive draining before applying a differ-
ent quality gas.
The instrument panel display shows information on the current natural gas
quality ⇒ page 73.
Natural gas and safety
If you can smell gas or suspect that there is a leak ⇒ 
:
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● Seek specialist assistance. Have the fault repaired.
WARNING
Failure to act when you can smell gas in the vehicle or when refuelling
can cause serious injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.
Note
Have natural gas system checked regularly by a specialised workshop in ac-
cordance with the Maintenance Programme. 

For the sake of the environment
Do not overfill the fuel tank – it may cause the fuel to overflow if it becomes
warm.
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 
Refuelling natural gas
Fig. 152 Tank flap open:
gas filler mouth 1, filler
mouth retainer 2
Before refuelling, the engine and the ignition, mobile telephone and heat-
ing must be switched off separately
⇒ .
Read the instructions on how to use the natural gas pump carefully.
The vehicle is not prepared for refuelling with liquefied natural gas (LNG)
⇒ 
. Before refuelling with natural gas, make sure to add the appropriate
type of fuel ⇒ page 246.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel tank cap, next to the petrol
filler mouth.
● Unlock the vehicle with the key or with the central locking button 
situ-
ated on the driver door ⇒ page 87.
● Press on the rear area of the flap and open it.
Refuelling
Thing to note: if the ambient temperature is very high, the natural gas pump
protection against overheating may disconnect this automatically.
● Remove the plug from the gas filler mouth ⇒ Fig. 152 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place. 

WARNING (Continued)
● Protect face, hands and arms by covering the cap with a large, thick
rag to protect against escaping coolant and steam.
● If it is necessary to work in the engine compartment while the engine
is running, the rotating components (for example, poly-V belt, alternator,
radiator fan) and the high voltage ignition system are an additional haz-
ard.
● Observe the following additional warnings if work on the fuel system
or the electrical system is necessary:
–Always disconnect the battery from the on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguisher immediately available.
CAUTION
When changing or topping up service fluids, make absolutely certain that
you fill the fluids into the correct reservoirs. Using the wrong fluids could
cause serious malfunctions and engine damage!
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
Note
On right-hand drive vehicles* some of the containers/reservoirs mentioned
below are located on the other side of the engine compartment. Opening the bonnet
The bonnet is released from inside the vehicle.
Fig. 153 Release lever in driver footwell and cam below the bonnet
Check that the windscreen wiper arms are not unfolded. Otherwise
the paint may be damaged.
The bonnet can only be unlocked when the driver door is open.
– Pull the lever under the dash panel in the direction of the arrow
1
⇒ Fig. 153.
– Lift the bonnet slightly ⇒ 
.
– Press the release catch under the bonnet upwards ⇒ Fig. 153
2
. This will release the arrester hook under the bonnet.
– Open the bonnet. Release the bonnet stay and secure it in fix-
ture designed for this in the bonnet. 

WARNING
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. Risk of poisoning!
● If the brake fluid is left in the system for too long and the brakes are
subjected to heavy use, vapour bubbles may form in the brake system.
This would seriously affect the efficiency of the brakes and the safety of
the vehicle. This may cause an accident.
CAUTION
Brake fluid should not come into contact with the vehicle paintwork, as it is
abrasive. 
Battery General information
The battery is located in the engine compartment and is almost mainte-
nance-free. It is checked as part of the Inspection Service. Nevertheless,
check the terminals are clean and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in exceptional cases. When the
battery is disconnected, some of the vehicle's functions are “lost” ( ⇒ table
on page 260). These functions will require resetting after the battery is re-
connected.
Deactivate the anti-theft alarm* before you disconnect the battery Other-
wise the alarm will be triggered.

Remote control keyIf the vehicle does not respond to the
key, they should be synchronised
⇒ page 91
Digital clock⇒ page 63
ESC warning lampAfter driving for a few metres, the
warning lamp goes out again.
If the vehicle is not used for long periods
The vehicle has a system for monitoring the current consumption when the
engine is left unused for long periods of time ⇒ page 226. Some functions,
such as the interior lights, or the remote door opening, may be temporarily
disabled to prevent the battery from running flat. These functions will come
back on as soon as the ignition is switched on and the engine started.
Winter conditions
During the winter, the starting power may be reduced, and if necessary, the
battery should be charged ⇒

vehicle battery on page 261 
Important safety warnings for handling a vehicle battery
All work on batteries requires specialist knowledge. Please refer to a SEAT
Official Service or a workshop specialising in batteries: risk of burns or ex-
ploding battery!
The battery must not be opened. Never try to change the fluid level of the
battery. Explosive gas is released from the battery that could cause an ex-
plosion. 
