Key programming
A maximum of eight keys with radio
frequency remote control can be
programmed (including the ones
delivered with the vehicle). The
keys must remain inside the vehicle
during the programming procedure.
Fasten the front seat belts and
close all doors to ensure that
conflicting chimes do not sound
during programming.
1. To programme new keys with
radio frequency remote control turn
the ignition key to position II four
times within six seconds.
2. Turn the ignition to position 0.
A tone sounds to indicate that it is
now possible to programme the
keys for 10 seconds.
3. Press any button on a new key.
A tone will sound as confirmation.
Repeat this last step for all your
keys with radio frequency remote
control, including your original
keys. Do not remove the key from
the ignition when pressing the
button on this key.
4. Switch the ignition back on
(position II ) or wait for ten seconds
without programming another key
to end the key programming. Only
the keys with radio frequency
remote control which you have just
programmed are now able to lock
and unlock your vehicle.
