GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-18281917) - 2025
230 Driving and Operating
vehicle is driven at no more than 9 km/h (6
m
p
h). An illuminated indicator in the Park
Assist button indicates the system is ready.
Sensors located in the bumpers measure the
distance between the vehicle and objects using
sonar technology.
Different environmental conditions may affect
whether and how far the Park Assist system can
detect objects. Keep the sensors clean of mud,
dirt, snow, ice, and slush; and clean sensors
after acar wash in freezing temperatures.
Sensors that are not clean may not detect
objects or may cause the system to alert when
not required.
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.
Beeps sound to warn the driver of certain
ob
jects that are detected around the vehicle.
The frequency of beeps increases as the vehicle
gets closer to the object. When the object
is very close to the vehicle, the beeps are
continuous. The beeps may be muted by
pressing the on screen mute button.
Turning the System On and Off
To
view available settings from the
infotainment home screen, touch Settings
>Vehicle >Collision/Detection Systems.
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
la
rger trailer hitches, as it can cause the system
to 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.
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 3323.
•
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.
