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 550
. 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 269
.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.
