The effective transmitting power does not

exceed 10 Watts at the aerial base.

Filling the tank

A SEAT Official Service and specialised work-

shop will be able to inform you about options

for installing and operating radio transmitters

with a higher transmitting power.

WARNING

Refuelling

Mobile telephones or radio equipment

which is operated inside the vehicle without

a properly installed external aerial can

create excessive magnetic fields that

could cause a health hazard.

Mobile radio transmitters

If the automatic filler nozzle is operated cor-

rectly, it will switch itself off as soon as the

fuel tank is “full”. Do not try to put in more fuel

after the nozzle cuts out, as this will fill the ex-

pansion chamber in the fuel tank.

Commercial mobile telephones or radio

equipment might interfere with the electron-

ics of your vehicle and cause malfunctions.

This may be due to:

Please note also that the maximum range of

the equipment can only be achieved with an

external aerial.

Every 6 months it is necessary to run on pet-

rol until the control lamp switches off  and

then the tank must be refilled. This is neces-

sary to ensure that the system works proper-

ly, as well as the fuel quality required for driv-

ing with petrol.

Retrofit installation of business or private

equipment in the vehicle is permitted, provi-

Diesel vehicles are fitted with a protective

device that prevents the insertion of the

wrong fuel hose¹⁾. It is only possible to re-

fuel with Diesel nozzles.

engine, the ignition must be switched on for

at least 30 seconds before starting the en-

gine. When you then start the engine it may

take longer than normal (up to one minute)

to start firing. This is because air needs to

be bled from the fuel system while starting.

If you fill the tank from a reserve fuel can-

have to carry a spare fuel canister, please

observe the following points:

ister, the protective device will not open.

One way to resolve this is to pour the fuel in

very slowly.

–

Never fill fuel into the spare fuel canis-

ter if it is inside or on top of the vehicle.

An electrostatic charge could build up

during filling, causing the fuel vapour to

ignite. Danger of explosion. Always

place the canister on the ground to fill

it.

For the sake of the environment

Do not overfill the fuel tank, it may cause

the fuel to overflow if it becomes warm.

–

Insert the filling nozzle as far as possi-

ble into the spare fuel canister.

–

If the spare fuel canister is made of

metal, the filling nozzle must be in con-

tact with the canister during filling. This

helps prevent an electrostatic charge

building up.
