Cadillac DTS Owner Manual - 2011
How the System Works
UFRPA comes on automatically when the shift lever is
moved out of P (Park). The system does not work at a
forward or reverse speed greater than 5 mph (8 km/h).
To be detected, objects must be at least 25.4 cm (10 in.)
off the ground and below hood or trunk level. Objects
must also be within 1.2 m (4 ft.) in front of the vehicle
and 2.5 m (8 ft.) from the rear bumper. This distance
may be less during warmer or humid weather.
When backing up, if objects are detected at the same
time near both the front and rear bumpers, both
color-coded light displays will notify you of objects close
to each bumper. If there are objects detected near both
bumpers, the beeps will only be sounded to notify that
objects are close to the rear bumper. However, if while
the vehicle is backing up and an object comes within
0.3 m (1 ft.) of the front bumper, and at the same time
there is another object further than 0.3 m (1 ft.) from the
rear bumper, then the beeps will only be sounded to
notify you of the closer object that is near the front
bumper.
The system can be disabled using the Driver
Information Center (DIC). See “Parking Assist” under
DIC Operation and Displays
on page 4‑60
for more
information.
Moving Forward
When the vehicle is started, the front display will briefly
illuminate to let you know the system is working.
The following describes what will occur with the front
display as you get closer to a object detected in the
