The display is located

near the rear window

and can be seen

by looking over your

right shoulder.

The display has three color-coded lights. The

URPA lights are used to provide distance and

system information, along with beeps played out

the speakers.

How the System Works

When the shift lever is moved into REVERSE (R),

the rear display will brieﬂy illuminate to let you know

the display is operating correctly. URPA comes on

automatically when the shift lever is moved into

REVERSE (R). The system also does not work at a

reverse speed greater than 5 mph (8 km/h). To

remind you of this, the red light on the rear display

will ﬂash.

The system can be disabled using the Driver

Information Center (DIC). See DIC Controls and

Displays on page 212.

How the System Works when Backing

If the shift lever is in REVERSE (R), URPA detects

objects close to the rear bumper. The ﬁrst time an

object is detected a single beep will sound. If an

object is detected at a REVERSE (R) speed

between 0 mph (0km/h) and 5 mph (8 km/h), the

following describes what will occur based on your

distance to a detected object located behind the

vehicle:

• At distances between 40 inches (1 m) and

8 ft (2.5 m), a single amber light will be lit.

• At distances between 23 inches (0.6 m) and

40 inches (1 m), both amber lights will be lit.

• At distances between 12 inches (0.3 m)

and 23 inches (0.6 m), all three lights

(amber/amber/red) will be lit.

• At distances less than 12 inches (0.3 m), a

beeping sound will repeat for a short time and

all three lights (amber/amber/red) will be lit and

ﬂashing.
