If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red when you are driving if a
trailer is attached to your vehicle, or if you have a bicycle
or an object hanging out of your trunk. The light will
continue to flash until the trailer or the object is removed
and your vehicle is driven forward at least 15 mph.
It may also flash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or the system may not
work properly. If after cleaning the rear bumper and then
driving at least 15 mph, the display continues to flash
red, see your dealer. It may also flash red if your vehicle
is moving in REVERSE (R) at a speed greater than
3 mph (5 km/h). Other conditions that may affect
system performance include things like, the vibrations
from a jackhammer or the compression of airbrakes on
a very large truck.
As always, drivers should use care when backing up
a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind spots.
For cleaning instructions, see “Cleaning Your Vehicle”
in the Index.
Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don’t park
over papers, leaves, dry grass or other things that
can burn.
