16, n° 11 and 12). If the LED is not illuminated:
• Check the status of the fuse. This can be found in
the fuse-holder, which is above the electrical box at
the base of the system. The fuse must be a 5x20
mm "fast blow fuse". 10A slow blow fuses are not
suitable.
• Check the Voltage to the red and black wires at the
base of the Roof system (see picture A page 12).

2) If the handbrake cut-out function is installed, check the relay or switch used to
signal that the handbrake is operating correctly. If necessary , try by by-passing
the hand-brake security function, by creating an electrical bridge between the
relevant contacts (refer to table on page 22).
3) Ensure you are executing the correct unlocking sequence on the remote
control (for the correct procedure, please refer to page 16).
