Are they turned off?

As above - the on/off setting is in the options screen. However, if the parking distance display is showing on the MFD but there is no beeping, it's possible the system is on but the volume has been turned down or off.

According to the manual that's a dealer-change option that isn't accessible through the settings or configuration menus. If you want it back on, it may be worth investing in a Carista dongle - that can definitely access the volume setting.
