2. Enter the FIRST digit of
the code.
If the first digit is 4,
turn the key (anti-clockwise)

FULLY returned to the centre position after
each turn of the key.
3. Enter the SECOND digit of
the code.
If the second digit is
3, turn the key to the LOCK

the key must be FULLY
returned to the centre position after each turn
of the key.
4. Enter the THIRD digit of
the code.
If the third digit is
2, turn the key to the UNLOCK
position twice, ensuring that
the key is FULLY returned to
the centre position after each turn of the key.
5. Enter the FOURTH digit of
the code.
If the fourth digit is

position once. Ensure the key
is FULLY returned to the
centre position after the key has been turned.
6. FINALLY,
turn the key to
the UNLOCK position once
more to disarm the alarm and
re-mobilise the engine. If the
code has been entered
