Buick 2004 Park Avenue - Manual (Page 140)

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 while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or 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 at least 15 mph
(25 km/h).
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 materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at at least
15 mph (25 km/h), the display continues to flash red,
see your dealer. For cleaning instructions, see Cleaning
the Outside of Your Vehicle on page 5-93.
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.
Accessory Power Outlets
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle has two power outlets located in the rear
storage area of the front center console. See Center
Console Storage Area on page 2-48 for more information
on location.
Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet. If it does,
when not using the outlet be sure to cover it with
the protective cap.
The accessory power outlets will only operate while the
ignition key is in RUN and for 10 minutes after turning
the ignition off. If you would like to operate an accessory
for an extended period of time, contact your dealer for
more information.
Notice: Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
