Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16060855) - 2023 - CRC - 2/9/22
224 Driving and Operating
How the System Works
The vehicle may have a Park
Assist amphitheatre-like display on the
cluster with bars that represent the
estimated location of a detected object and
the vehicle’s distance from the object. As a
detected object becomes closer, more bars
light up and change color from yellow to
amber to red. Vehicles equipped with RPA
will show the amphitheater at the rear of
the vehicle, and if equipped, FRPA will show
the amphitheater at the front and rear.
When an object is first detected in the rear,
one beep will be heard from the rear, or the
driver seat will pulse two times, if equipped
with Safety Alert Seat. When an object is
very close, five beeps will sound from the
front or rear (depending on the object's
location), or the driver seat will pulse five
times. Beeps for front are higher pitched
than the rear.
Turning the System On and Off
The
X button is used to turn on or off
the Park Assist, which also turns on or off
the Backing Warning and Reverse Automatic
Braking (RAB) at the same time. When the
system is turned off, a system off message
is shown on the display. This message
disappears after a short period of time.
If the vehicle has a trailer hitch attached,
select ON - ATTACHED using the
infotainment system menus to allow Park
Assist to function properly. Park Assist is
able to compensate for a trailer hitch up to
0.3 m (1 ft) in length and width. Park Assist
may not function properly with larger trailer
hitches and provide inaccurate information
of objects in the rear.
Turn off Park Assist when towing a trailer to
prevent unwanted beeps and when a bike
rack is attached to ensure proper operation.
To view available settings for this feature,
touch the Settings icon on the infotainment
home page. Select “Vehicle” to display the
list of available options and select “Collision/
Detection Systems”.
When the System Does Not Seem to Work
Properly
If a service message displays, check the
following conditions:
.
The sensors may not be clean. Keep the
vehicle's front and rear bumpers free of
mud, dirt, snow, ice, and slush. For
cleaning instructions, see Exterior Care
0 304.
.
The Park Assist sensors may be covered
by frost or ice. Frost or ice can form
around and behind the sensors and may
not always be seen; this can occur after
washing the vehicle in cold weather. The
message may not clear until the frost or
ice has melted.
If a service message displays and the above
conditions do not exist, take the vehicle to
your dealer for repairs.
