Adding accessories can affect the vehicle
performance. See Accessories and
Modifications 0270.
Hill Descent Control (HDC)
If equipped, HDC can be used when driving
downhill. It sets and maintains vehicle speed
while descending a very steep incline in a
forward or reverse gear.
The HDC switch is on the center console. Press
5to enable or disable HDC. Vehicle
speed must be below 50 km/h (31 mph).
A blinking HDC light indicates the system is
actively applying the brakes to maintain
vehicle speed.
HDC can maintain vehicle speeds between
3–22 km/h (2–14 mph) on an incline greater
than or equal to a 10% grade.
When HDC is activated, the initial HDC
speed is set to the current driving speed.
It can be increased or decreased by pressing
the RES+ or SET– steering wheel controls or
by applying the accelerator or brake pedal.
This adjusted speed becomes the new set
speed.
HDC will remain enabled between
22–60 km/h (14–37 mph); however vehicle
speed cannot be set or maintained in this
range. It will automatically disable if the
vehicle speed is above 80 km/h (50 mph) or
above 60 km/h (37 mph) for at least
30 seconds. Press
5again to re-enable HDC.

Driving and Operating 229
Driver Mode Control
If equipped, the Driver Mode Control has the
following Modes: Tour (FWD), Sport,
All-Wheel Drive (AWD), Snow/Ice, Tow/Haul,
and Off-Road. Rotate the Driver Mode
Control knob on the center console to make
a mode selection. Continue turning the knob
through the available modes. The selected
mode’s icon will light up on the knob and
there may be additional messages in the
Driver Information Center (DIC) and
indicators in the instrument cluster.
If the vehicle is in Tour (FWD) or AWD, it
will stay in that mode through future
ignition cycles. If the vehicle is in any other
mode, it will revert back to Tour (FWD)
when the vehicle is restarted.
Driver Mode Control Knob (AWD)
Driver Mode Control Knob (FWD)
5orqTour (FWD) :Vehicle is in Tour
(FWD) Mode. Use this mode during normal
driving conditions. See Driving for Better Fuel
Economy 0200. Tour (FWD) Mode operates
in Front-Wheel Drive to improve fuel
economy.
8Sport : Sport Mode improves vehicle
handling and acceleration on dry pavement.
When active, Sport Mode modifies steering
efforts, transmission shifting, and suspension
tuning (when equipped). For AWD vehicles,
choosing Sport Mode also engages
AWD Mode.
The Performance Algorithm Liftfoot (PAL)
feature is enabled in Sport Mode. PAL allows
the transmission to hold the current gear
after a quick release of a heavily applied
accelerator pedal. This provides greater
engine braking and enhanced vehicle control.
4AWD (AWD Only) : AWD Mode
provides drive torque to all four wheels.
Select AWD to improve traction and control
on slippery road surfaces, such as gravel,
sand, wet pavement, snow, and ice. When in
AWD Mode, the AWD Mode indicator will be
on. The AWD Mode will stay selected until
the mode is changed.

246 Driving and Operating
pulses occur on the left or right side,
depending on the direction of the detected
vehicle.
Driving With a Trailer
Use caution while backing up when towing
a trailer. The RCTA feature is automatically
disabled when a trailer is attached to the
vehicle.
Turning the Features On or Off
The
Xbutton on the center console is
used to turn on or off Rear Park Assist (RPA)
and RCTA at the same time. The indicator
light in the button comes on when the
features are on and turns off when the
features have been disabled.
Turn off RPA and RCTA when towing a
trailer.
RCTA can be turned on or off using the
infotainment system. See “Collision/
Detection Systems” underVehicle
Personalization 0124.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Lane Departure Warning (LDW), Lane Keep
Assist (LKA), Side Blind Zone Alert (SBZA),
Lane Change Alert (LCA), Automatic
Emergency Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System can help to
avoid a crash or reduce crash damage.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps or pulses the driver seat. FCA
also lights an amber visual alert if following
another vehicle too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC), it can
detect vehicles to distances of approximately
110 m (360 ft) and operates at all speeds.
See Adaptive Cruise Control (Advanced)
0 232.
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive Driving
0 201.
FCA can be disabled. See “Collision/Detection
Systems” underVehicle Personalization
0 124.
Detecting the Vehicle Ahead

GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-15170041) - 2022 - CRC - 10/6/21
254 Driving and Operating
Warning (Continued)
Always keep your attention on the road
and maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always keep
the windshield, headlamps, and camera
sensors clean and in good repair. Do not
use LKA in bad weather conditions or on
roads with unclear lane markings, such as
construction zones.
{Warning
Using LKA while towing a trailer or on
slippery roads could cause loss of control
of the vehicle and a crash. Turn the
system off.
How the System Works
LKA uses a camera sensor installed on the
windshield ahead of the rearview mirror to
detect lane markings. It may provide brief
steering assist if it detects an unintended
lane departure. It may further provide an
audible alert, or the driver seat may pulse,
indicating that a lane marking has been
crossed.To turn LKA on and off, press
Aon the
center console. If equipped, the indicator
light on the button comes on when LKA is
on and turns off when LKA is disabled.
When on,
Ais white, if equipped,
indicating that the system is not ready to
assist.
Ais green if LKA is ready to
assist. LKA may assist by gently turning the
steering wheel if the vehicle approaches a
detected lane marking.
Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
Aamber if the vehicle crosses a
detected lane marking. Additionally, there
may be three beeps on the right or left,
or the driver seat may pulse three times,
depending on the lane departure direction.
Take Steering
The LKA system does not continuously steer
the vehicle. If LKA does not detect active
driver steering, an alert and chime may be
provided. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.
.Banked roads.
.Roads with poor lane markings, such as
two-lane roads.
If the LKA system is not functioning
properly when lane markings are clearly
visible, cleaning the windshield may help.
A camera blocked message may display if
the camera is blocked. Some driver
assistance systems may have reduced
performance or not work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera.
The LKA system does not need service. Clean
the outside of the windshield behind the
rearview mirror.
LKA assistance and/or LDW alerts may occur
due to tar marks, shadows, cracks in the
road, temporary or construction lane
markings, or other road imperfections. This
