Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 1.5 m (5 ft)
behind the vehicle, and at least
25 cm (10 in) off the ground.

WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.
Objects that are below the
bumper, under 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 up,
vehicle damage, injury, or death
could occur. Even with URPA,
always check behind the vehicle
before backing up. While backing
up, 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 8 km/h (5 mph).
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 cm (10 in) off the ground
and below trunk level. Objects must
also be within 1.5 m (5 ft) from the
rear bumper. The distance at which
objects can be detected may be
less during warmer or humid
weather.
