The system 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.

To disable URPA, see DIC Operation and Displays

(With DIC Buttons) on page 233 and DIC

Operations and Displays (Without DIC Buttons)

on page 239.

URPA automatically turns back on each time

the vehicle is started.

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 (0 km/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 come on.

• At distances between 23 inches (0.6 m) and

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

• At distances between 12 inches (0.3 m) and

23 inches (0.6 m), all three lights (amber/

amber/red) will be on.

• 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 ﬂash.

When the System Does Not Seem to

Work Properly

If the URPA system will not activate due to a

temporary condition, the message PARK ASSIST

OFF will display on the DIC screen and a red

light will come on the URPA display when the shift

lever is moved into REVERSE (R). This occurs

under the following conditions:

• The parking brake pedal is depressed.

• A trailer was attached to your vehicle, or a

bicycle or an object was hanging out of

your trunk during your last drive when you

turned off the vehicle. If the attached objects

are removed from your vehicle before the start

of your next drive, the system will return to

normal operation unless an object is detected

when the vehicle is shifted into REVERSE (R).
