I have an 04, N*. Whenever I shift out of park to either reverse, or straight in to drive, I get (hear) four chimes (or bongs). If I go from drive to reverse, no sounds, but if I return to park, the sounds repeat. It seems that once in park, anything that goes past reverse causes the chimes (bongs).
I don't use the car everyday, and my wife cannot remember if it ever did anything different, so what sounds are normal when shifting into reverse or drive?

That is the Ultrasonic Rear Park Assist.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system turns on, the
three lights on the display will illuminate for one
and a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R) at a
speed greater than 3 mph (5 km/h), the red light will
flash to remind you that the system does not work at a
speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of
less than 3 mph (5 km/h), one of the following will occur:
Description English Metric
Amber light 5 ft 1.5 m
Amber/amber lights 40 in 1.0 m
Amber/amber/red lights &
continuous chime 20 in 0.5 m
flashing & continuous chime 1 ft 0.3 m
A chime will sound the first time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
URPA cannot detect objects that are above liftgate level.
In order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.
So, even when there is absolutely nothing behind the car, and the shift lever passes reverse, there will be 4 chimes?

Don73, my '04 did exactly the same thing recently, for about six weeks, and is now back to "normal." It did not do that from the time it was delivered until the recent six-week episode. Once, towards the end of the six-week period, I opened the driver door in the garage, after the usual overnight park, and constant "bonging" started; car had been unlocked, no key in the ignition, etc. The noise stopped after the door was closed; next day, the four bong when shifting into reverse stopped.
I think the electronic spirits left mine for yours!
no. unless you shift into reverse and punch it and go over 3 mph. sounds like yours is malfunctioning.
Thanks everyone. Looks like another trip to the dealership. I'll report on the outcome.
