If tell-tale light 1comes on or remains
lit after the ignition has been switched
on, this indicates that the system is not
operating correctly.
In all cases, it is essential to contact
an approved Dealer as only they are

liser.

the second key (supplied with the ve-
hicle), when tell-tale light 1begins to
flash rapidly after the ignition has been
switched on. If you do not have access
to this, it is essential to contact an ap-
proved Dealer. Only approved Dealers
are authorised to repair the engine im-
mobiliser system.

carried out on the engine
immobiliser (computers,

gerous. Work must be carried out
by qualified personnel.
