Do Not Use ACC on Hills
Do not use ACC when driving on steep hills
as ACC may not detect a vehicle ahead.
Towing with ACC
If equipped when towing a trailer, ACC
driving characteristics such as following gap,
acceleration rates and braking rates may be
modified to provide a better towing
experience.
When ACC is used with vehicles equipped
with aftermarket trailer brake controller,
disengage ACC before applying the manual
trailer brake. ACC will not automatically
disengage when manual trailer brake is
applied.
ACC may be used when towing a trailer
when trailer attached is within GM-approved
allowable size and weight limits. See Trailer
Towing 0 224.
When towing a trailer with ACC, it is
important to properly set the Trailer Gain.
See "Integrated Trailer Brake Control
System" in Towing Equipment 0 227 for
more information about the Trailer Gain
adjustment procedure.
Use Tow/Haul mode when driving down
steep hills or mountain grades, or when
hauling heavy loads. See Driver Mode
Control 0 180.
ACC maintains the set speed when driving
uphill and downhill while towing a trailer.
However, ACC may make a slight change to
the cruise speed while driving on moderate
hills if the combined vehicle and trailer
weight is close to the maximum Gross
Combined Weight Rating (GCWR). See Trailer
Towing 0 224. This is normal ACC operation
and is necessary to maintain the set speed.
ACC may disengage if it detects that the
brake temperature exceeds the normal
temperature range.
Disengaging ACC
There are three ways to disengage ACC:
. Lightly apply the brake pedal.

Driving and Operating
Erasing Speed Memory
The ACC set speed is erased from memory if
J
is pressed and when the vehicle is
turned off.
Weather Conditions Affecting ACC
If the interior temperature is extremely
high, the instrument cluster may indicate
that ACC is temporarily unavailable. This can
be caused by extreme hot weather
conditions with direct sunlight on the front
camera. ACC will return to normal operation
once the cabin temperature is lower.
Conditions that are associated with low
visibility, such as fog, rain, snow, or road
spray, may limit ACC performance. Water
droplets from rain or snow that remain on
the windshield may also limit ACC's ability
to detect objects.
{
Warning
Camera visibility may be limited and the
ACC system may not work properly if the
windshield is not clear. Do not use ACC if
moisture is present on the inside of the
windshield or the windshield washer is
used in cold weather. Turn on the front
