Immobilizer
• Set the start switch key to position "0".
• The immobilizer is automatically activated after
5 sec.
• The immobilizer becomes and remains activated if
the key remains inserted in position "0".
Deactivating the immobilizer
• Set the start switch key to position “1”.
• The transponder is not read until the mechanical
key in the start switch has activated terminal 15.
This makes it necessary to first open the
mechanical locking system before the electronic
key is inspected. A manipulation of the immobilizer
with the ignition deactivated is thereby impossible.
Note
The immobilizer is self-activating; that is,
without additional activation or divergent
actions.
If the mechanical start switch is in
position "0" (terminal 15 off), the
immobilizer is generally activated.
Note
The immobilizer is deactivated if a valid
mechanical key and a valid electronic key
(transponder) are present.
