Key programming
A maximum of four keys with radio
frequency remote control
(including the ones delivered with
the vehicle) can be programmed.
1. To programme new keys with
radio frequency remote control
turn the ignition key to position II
four times within six seconds.
2. Switch off the ignition. 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.
4. Switch the ignition back on 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.
Note: To code keys for the engine
immobilisation system, refer to the
section Key coding.
Controls and features
Replacing the battery
If the range of the transmitter in
the key decreases gradually, the
battery (type 3V CR 2032) should
be replaced.
• Carefully separate the transmitter
unit from the key using a flat object
(e.g. a screwdriver) at the recess
on the back.
• Open the transmitter unit by
separating the retaining clips on
the sides with the flat object.
• Carefully prise out the battery
with the flat object. Fit the new
battery between the contacts with
the (+) sign facing upwards.
Reassemble the transmitter unit in
reverse order.
