Any idea on how to reduce the volume of reversing warning beep on my15 SD4 SE?? MY 09 GS manual in Lago Grey, Wood Co arm rest and side bumper strips - now sold.

I don't think that is a driver option - it is not mentioned in the handbook so I suspect it is a programming function by stealers No Longer the owner of a 2013MY Fuji White GS

"Fiat Lux" a philosophy not a car

You can on mine. Just press the set-up button then go into System, there you can adjust the sound levels. Not sure if this feature is on all specs. MY13 HSE LUX Aintree Green

As said it is in the setup menu, although it only goes down to a default minimum and that is quite loud.

Are we talking "Audible Reverse Warning" (CCF Edit) or rear park assist?
Do you have "7 touchscreen or 5" display screen?

"Audible Reverse Warning" is selectable within the CCF, not sure which markets need this feature active and I've never bothered to activate it. If this is what you mean try, whilst reverse is selected and audible warning activated, use volume control on either integrated control panel (centre consul) or steering wheel to lower volume if you have 5" display screen. Same procedure if your talking about rear PDC warnings.

I possibly may activate "Audible Reverse Warning" next time I connect to see if any extra customisable features appear on touchscreen or driver configuration screen.

I'd be curious to know if "Audible Reverse Warning" is what we are talking about here as I never heard of it being active for any market so yours is a anomaly!
Only market i can think of is some Asian regions. MY15

Like the phone and satnav volume, adjust the reverse beep warning volume by using the radio volume button when you are in reverse and it's beeping. Well, that's how it works on my Evoque. Goes from ear splitting to very quiet. Past: FL2 TD4 HSE Auto

Thanks for all comments and will report back - upgraded from GS to SE but some things are retrograde viz, radio doesn't reduce in volume when in reverse , no automatic lights and no auto windscreen wipers but you do get heated seats which I never use. MY 09 GS manual in Lago Grey, Wood Co arm rest and side bumper strips - now sold.

Well I tried the radio volume button - no go. The SE (special Equipment ) ain't so special as it has the small screen and when you pull up the menu there is no facility to reduce the audible beep. Lived with it for a year plus so will continue to enjoy as the SD4 auto is infinitely better than the TD4 manual that preceeded it.
