WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
. Objects that are below the
bumper, underneath the
vehicle, or too close or far
from the vehicle
. Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing, vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 5 mph (8 km/h).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeps are
continuous.
To be detected, objects must be at
least 25.4 cm (10 in) off the ground
and below liftgate level. Objects
must also be within 2.5 m (8 ft) from
the rear bumper. This distance may
be less during warmer or humid
weather.
The system can be disabled through
the Driver Information Center (DIC).
See “Park Assist” under Vehicle
Personalization on page 5‑40 for
more information.

Seem to Work Properly

activate due to a temporary
condition, the message PARK
ASSIST OFF or PARK ASST
BLOCKED SEE OWNERS
MANUAL will be displayed on
the DIC.
SERVICE PARK ASSIST: If this
