Horn - Horn
Description and Operation
The horns, located behind the radiator gril le, each side of the radiator, are controlled by the Body Processor Module (BPM),
as described below.
The switch, located on the steering wheel pad, is operated, it signals the BPM to sound the horn. The BPM responds by
providing an earth from the horn-output to the horn relay coil. The relay contacts are subsequently closed and the horns
sound.
The horn operating relay, R6 is located in the engine compartm ent fusebox at the left hand side of the engine compartment.

Clock - Clock
Description and Operation
The analogue clock is mounted in the center of fascia vent assembly and can only be removed after withdrawal of the fascia
vent assembly.
The clock is protected by a 5A fuse in lo cation F6 of the LH heelboard fusebox and illumination is controlled by the dimmer
module in the same manner as the other instruments.
The time displayed can be advanced using the positive button and retarded using the minus button.
