compression ratio BUICK PARK AVENUE 2003 Owner's Manual

If the URPA system is not functioning properly, the
display will ¯ash red, indicating that there is a problem.
The light will also ¯ash 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 ¯ash 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 ¯ash red if the ultrasonic sensors
are not kept clean. For cleaning instructions, see
Cleaning the Outside of Your Vehicle on page 5-82.
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 at least 15 mph (25 km/h), the display
continues to ¯ash red, see your dealer. It may also ¯ash
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.
