Park Assist - GMC HUMMER EV 2023 Owner's Manual

Performance for Rear Trailer Guidance
Lines and Trailer Length Indicator Overlays
are optimized when the entered value for
trailer width reflects the total width of
the trailer including outboard wheels.
If the trailer box width is entered:
The Rear Trailer Guidance Lines will
appear narrower than the actual path
of the trailer.
The Trailer Length Indicator Overlays
will appear closer and possibly overlap
with the trailer.
Underbody Camera
There are two cameras underneath the
vehicle that show a view of the areas
underneath the front and rear bumper. This
feature is activated through the
infotainment display.
The cameras can be washed by the
following procedure:
1. Touch CAMERA on the infotainment
display.
2. Select the front/rear underbody
camera view.
3. Choose which camera to wash. Only one
can be washed at a time and the screen
cannot be split between both.
4. Touch the symbol on the lower-left of
the infotainment display to activate the
washer.
If there is excessive or dry debris on the
shield in front of the camera lens, the
activated washer may not effectively clean
it. A manual cleaning may be necessary.
Excessive or prolonged use may cause
damage to the shield. Periodic service or
replacement may be required.

Park Assist

With Front and Rear Park Assist, as the
vehicle moves at speeds of less than 8 km/h
(5 mph) the sensors on the bumpers may
detect objects up to 1.2 m (4 ft) in front and
Driving and Operating
2.5 m (8 ft) behind the vehicle within a zone
25 cm (10 in) high off the ground and below
bumper level. These detection distances may
be shorter during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects located below the bumper or
that are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To prevent
injury, death, or vehicle damage, even
with Park Assist, always check the area
around the vehicle and check all mirrors
before moving forward or backing.
