After the engine is switched off the radiator
f an may run on for up to 10 minut es, e

ven if

.
Inside the k

ey there is a chip that deactivates
the electronic immobiliser automatically
when the key is inserted into the ignition.
The electronic immobiliser will be activated
again automatically as soon as you pull the
key out of the ignition lock. For vehicles with
the “Keyless Access” system, the key has to
be outside the vehicle.
If the following message is shown on the in-
strument panel display: SAFE , the vehicle
cannot be started.
The engine can only be started using a genu-
ine SEAT key with its correct code. Note
A perfect operation of the vehicle is ensur-
ed if genuine SEAT keys are used. Emergency starting function
