How
the
System
Works
Unless disabled, the
URPA
will turn on automatically
when the shift lever is moved into REVERSE (R). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let you know
that the system is working.
If
your vehicle is moving in
REVERSE
(R)
at a speed greater than
3
mph
(5
km/h),
the red light will flash
to
remind you that the system
does not work at speed greater than
3
mph
(5
km/h).
If
an object is detected at a REVERSE
(R)
speed of less
than
3
mph
(5
km/h), one of the following will occur:

A
chime will sound the first time an object is detected
between
20
inches
(0.5
m) and
5
feet
(1.5
m) away.
URPA cannot detect objects that are above liftgate level.
In order for the rear sensors
to
recognize an
object,
it
must be within detection range behind the vehicle.
When the System Does Not Seem
to
Work
Properly
The light may flash red when the vehicle is in
REVERSE
(R)
if
the ultrasonic sensors are not kept
clean.
So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck.
If
after cleaning the
rear bumper and then driving forward at least
15
mph
(25
km/h), the display continues to flash red, see
your dealer.
If
a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out
of
your
liftgate during your last drive cycle, the light may
also flash red. The light will continue to flash whenever
in REVERSE
(R)
until your vehicle is driven forward
at least
15
mph
(25
km/h) without any obstructions
behind the vehicle.
