Acura 2011 RL - Manual (Page 383)

If equipped
Your vehicle has a backup sensor
system. This system lets you know
the approximate distance between
your vehicle and most obstacles with
an audible signal while you are
parking.
The sensors are installed in the rear
bumper. There are two corner
sensors, one on each side, and two
center sensors in the middle of the
rear bumper.
The system is activated and a beeper
sounds once when you put the
transmission into reverse. As your
vehicle is nearing an obstacle, the
system makes the audible signal to
let you know the approximate
distance between your vehicle and
the obstacle. If there are more than
two obstacles around the rear
bumper, the system informs you of
the nearest obstacle’s distance from
the rear bumper.
All obstacles may not always be
sensed. Even with this system, you
should look for obstacles near your
vehicle to make sure it is safe to park.
The beeping changes according to
the distance between the rear
bumper and an obstacle:
