CHEVROLET Tahoe - Manual (Page 225)

• The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush.
For cleaning instructions, see Washing Your
Vehicle on page 557. If the DIC still displays
the PARKING ASSIST OFF message
after cleaning the bumper and driving forward
at a speed of at least 15 mph (25 km/h),
see your dealer.
• Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
• When URPA is disabled without driver
action and the driver attempts to turn URPA
back on by pressing the rear park aid
button, the indicator light will flash for
3 seconds and then stay lit to indicate that
URPA is off.
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 Driver Information Center messages related to
URPA, see DIC Warnings and Messages on
page 270.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
Accessory power outlets can be used to
connect auxiliary electrical equipment, such as a
cellular telephone or CB radio. The outlet can
accept electrical equipment up to a maximum of

There are four accessory power outlets. There are
