Details and Technology
When reverse gear is selected with the ignition switched on, an exterior audible signal is activated. If
reverse gear is engaged twice within four to five seconds, the volume of the reversing warning signal
switches to the quieter setting. The reversing warning system cannot be switched off. Switching off the
ignition reactivates the default setting. The horn for the reversing warning system is normally fitted on the
inner side of the end crossmember. A sticker stating that reverse gear should be engaged twice in quick
succession to set the reversing beeper to the nighttime (quieter) setting is enclosed with the vehicle
document wallet.
