Horn

Horn: Tx

The transmitter of the horn signal from the centre-push button of the steering wheel is housed within the centre of the steering wheel, behind the push-button.

To replace the battery, the centre hub of the steering wheel has to be dismantled. A small lithium button cell is used to power the transmitter and was last replaced in early 2026.
