GMC Canyon/Canyon Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-16510661) - 2023 - CRC - 11/29/22
Driving and Operating 185
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 151.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily prevents the
vehicle from rolling in an unintended
direction during the transition from brake
pedal release to accelerator pedal apply. The
brakes release when the accelerator pedal is
applied or automatically release after a few
seconds. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and Electronic Stability Control (ESC).
These systems help limit wheel spin and
assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses any of the drive
wheels are spinning or beginning to lose
traction. When this happens, TCS applies the
brakes to the spinning wheels and reduces
vehicle power to limit wheel spin.
The TCS and ESC calibrations are different
while in Off Road, Terrain, or Baja mode,
if equipped. They provide optimum
performance in various off-road
environments.
ESC activates when the vehicle senses a
difference between the intended path and
the direction the vehicle is actually traveling.
ESC selectively applies braking pressure to
one or more of the vehicle wheel brakes to
assist the driver in keeping the vehicle on
the intended path. Trailer Sway Control (TSC) is also on automatically when the
vehicle is started. See
Trailer Sway Control
(TSC) 0242.
If using cruise control and ESC begins
limiting wheel spin, cruise control will
automatically disengage. You can turn cruise
control back on when road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See If the
Vehicle Is Stuck 0161 and “Turning the
Systems Off and On” later in this section.

Driving and Operating 189
Do not lock the front axle while in Terrain
Mode when driving on slippery roads. If the
front axle is locked while in Terrain mode,
the ABS warning light appears indicating
that ABS is off, which may result in the
wheels locking during deceleration. See
Locking Front Axle0192.
When the vehicle comes to a stop on an
upward grade, Automatic Vehicle Hold is
engaged until the accelerator pedal is
pressed. Start/Stop and cruise control are
disabled in Terrain Mode.
Active Braking will be engaged while in
Terrain Mode when vehicle speed is less
than 48 km/h (30 mph). Terrain mode will
not operate at speeds exceeding 80 km/h
(50 mph).
In D (Drive) and 4
n, moderate braking is
applied until the vehicle comes to a stop. In
D (Drive) and 4
m, moderate braking is
applied until the vehicle is at idle speeds. In
4
nor 4mand L1 or L2, the braking is applied
until the vehicle comes to a stop. In 4
nor
4
mand in L3-L8, the braking is applied until
the vehicle is at idle speeds. Terrain Mode will automatically exit to
Normal Mode if the brake or transmission
temperatures become too hot, the Electronic
Parking Brake (EPB) becomes inoperable, the
vehicle cannot perform braking or vehicle
hold, or if the transfer case is shifted out of
4
mor 4n.
For more information on off-road driving,
see Off-Road Driving 0153 and
Hill and Mountain Roads 0159.
_Tow/Haul Mode : Use this mode
when towing heavy loads to provide
increased performance and vehicle control.
Tow/Haul mode adjusts steering, pedal map,
transmission shift points, ABS, ESC, TCS
performance, and uses Trailer Sway
Control (TSC).
If equipped with only Normal and Tow/Haul
modes, there may be a Tow/Haul mode
button on the drive mode control knob or
center stack. Press
_to enter the mode. If the vehicle is turned off with Tow/Haul
Mode active and then restarted within four
hours or less, Tow/Haul will remain active.
Otherwise, the vehicle will start in
Normal Mode.
For more information on Tow/Haul mode,
see
Towing Equipment 0236.
9BAJA Mode (AT4x) : Use this mode for
off-road recreational driving at higher
speeds. This mode is not designed for
on-road usage. Hard packed sand, dirt, and
gravel are examples of surfaces that support
high speed driving. Baja mode can be
activated in all transfer case states.
Baja mode adjusts the steering, pedal map,
Four-Wheel Drive Auto, transmission shift
points, ABS, ESC, and TCS performance in
order to maximize response at higher vehicle
speeds. If enabled, the rear lockers will
remain locked at all speeds.
Baja mode optimizes ABS performance to
decrease stopping distances for deformable
or loose surfaces.

Caution
If you try to lock the axle while the
vehicle is stuck and the tires are spinning,
the vehicle’s drivetrain could be damaged.
The repairs would not be covered by the
vehicle warranty. Always lock the axle
before attempting situations and/or
navigating terrain that could cause the
vehicle to become stuck.
Caution
If the vehicle’s axle is locked while driving
on pavement, the drivetrain could be
damaged. Repairs would not be covered
by the vehicle warranty. Do not use the
locking axle on pavement.
{Warning
Driving on pavement with a locked front
axle may cause reduction to or complete
loss of steering assist, which could result
in serious injury, death, or property
damage. Do not use the locking front
axle on pavement.Before the front axle can be locked, the
transfer case must be in 4
n.
To lock the front axle, press the front/rear
axle locking switch. If it was not already
locked, the rear axle will lock first followed
by the front axle
To lock the front and rear axles: 1. Place the transfer case in 4
n. This is the
only mode that allows the front axle to
lock. See Four-Wheel Drive 0179 for
more information regarding the transfer
case and four-wheel drive low operation.
2. Press the front/rear axle locking switch with the vehicle stopped or moving less
than 30 km/h (20 mph).
3. Wait for the light in the switch to stop flashing and remain illuminated to show
that the front axle is locked. Engagement
of the front axle lock will disable the
Antilock Brake System (ABS) and
illuminate the ABS warning light. The
wheels may lock up in this condition
when decelerating from either applying
the brake pedal or automatic braking in
Terrain Mode. See Driver Mode Control
0 187. If this occurs, press the accelerator pedal to unlock the wheels. Hill Decent
Control (HDC) will also be disabled when
the front axle lock is engaged.
If the electronic locking differential has
difficulty engaging, release the
accelerator pedal.
To unlock the front axle, perform one of the
following actions:
‐ Press the rear axle locking switch. The
front axle unlocks and the rear axle
remains locked. See Locking Rear Axle
0 191.
‐ Press the front/rear axle locking switch.
The front and rear axles both unlock.
The locking front axle will be disengaged
when the vehicle speed exceeds 30 km/h
(20 mph) or the transfer case is shifted out
of 4
n.
ABS will be automatically enabled and the
ABS warning light will turn off when the
locking front axle is disengaged.
Do not lock the front axle while in Terrain
Mode when driving on slippery roads. If the
front axle is locked while in Terrain mode,
the ABS warning light appears indicating

GMC Canyon/Canyon Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-16510661) - 2023 - CRC - 11/29/22
194 Driving and Operating
that ABS is off, which may result in the
wheels locking during deceleration. See
Driver Mode Control0187.
If HDC was enabled prior to axle lock, it will
be automatically enabled when the locking
front axle is disengaged.
After pressing the switch to unlock the axle,
it may remain locked due to torque in the
driveline. The axle is more easily unlocked
by turning the steering wheel to the right
and to the left while traveling at a low
speed.
Cruise Control
With cruise control a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot on
the accelerator. Cruise control does not work
at speeds below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic. (Continued)
Warning (Continued)
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
If the cruise control is being used and the
Traction Control (TCS) system or StabiliTrak/
Electronic Stability Control (ESC) begins to
limit wheel spin, the cruise control will
automatically disengage. See Traction
Control/Electronic Stability Control 0185. If a
collision alert occurs when cruise control is
activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0215.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
If equipped with Hill Descent Control (HDC),
cruise control will disengage if HDC is Active.
If the brakes are applied, the cruise control
disengages.
5: Press to turn the system on or off.
A white indicator comes on in the
instrument cluster when cruise control is
turned on.
+RES : If there is a set speed in memory,
press briefly to resume to that speed or
press and hold to accelerate. If cruise control
is already active, use to increase vehicle
speed.
−SET : Press briefly to set the speed and
activate cruise control. If cruise control is
already active, use to decrease vehicle
speed.

196 Driving and Operating
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The
following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 0185. When road
conditions allow ACC to be safely used, ACC can be turned back on. Disabling the TCS or
StabiliTrak/ESC system will disengage and
prevent engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
{Warning
ACC has limited braking ability and may
not have time to slow the vehicle down
enough to avoid a collision with another
vehicle you are following. This can occur
when vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
later in this section.
Complete attention is always required
while driving and you should be ready to
take action and apply the brakes. See
Defensive Driving 0151.
{Warning
ACC will not detect or brake for children,
pedestrians, animals, or other objects.
Do not use ACC when:
.On winding and hilly roads or when
the sensors are blocked by snow, ice,
or dirt. The system may not detect a
vehicle ahead. Keep the entire front of
the vehicle clean.
.Visibility is poor due to rain, snow,
fog, dirt, insect residue, or dust; when
other foreign objects obscure the
camera and/or radar; or when the
vehicle in front or oncoming traffic
causes additional environmental
obstructions, such as road spray. ACC
performance is limited under these
conditions.
.On slippery roads where fast changes
in tire traction can cause excessive
wheel slip.
.With extremely heavy cargo loaded in
the cargo area or rear seat, or when
the vehicle is loaded in excess of load
limits. See Vehicle Load Limits 0162.

202 Driving and Operating
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle (Continued)
Warning (Continued)
ahead changing lanes. Your vehicle may
not stop and could cause a crash. Use
caution when using ACC. Your complete
attention is always required while driving
and you should be ready to take action
and apply the brakes.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles in front of your vehicle that have
a rear aspect that is low, small,
or irregular
.An empty truck or trailer that has no
cargo in the cargo bed
.Vehicles with cargo extending from the
back end
.Non-standard shaped vehicles, such as
vehicle transport, vehicles with a side car
fitted, or horse carriages
.Vehicles that are low to the road surface
.Objects that are close to the front of your

Regular Cruise Control”previously in this
section. Always consider driving conditions
before using either cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind a
detected vehicle and slow your vehicle to a
stop behind that vehicle.
If the stopped vehicle ahead has driven
away and ACC has not resumed, the vehicle
ahead indicator will flash as a reminder to
check traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat (if equipped) will pulse
three times, or three beeps will sound.
Touch the Settings icon on the infotainment
home page. Select “Vehicle”to display the
list of available options and select ”Alert
Type” and“Adaptive Cruise Go Notifier” in
“Collision/Detection Systems”.
When the vehicle ahead drives away, ACC
resumes automatically if the stop was brief.
If necessary, press +RES or the accelerator
pedal to resume ACC. If stopped for more
than two minutes or if the driver door is
opened and the driver seat belt is
unbuckled, the ACC automatically applies the
Electric Parking Brake (EPB) to hold the vehicle. The EPB status light will turn on.
See
Electric Parking Brake 0183. To release
the EPB, press the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before exiting
the vehicle.
{Warning
If ACC has stopped the vehicle, and if ACC
is disengaged, turned off, or canceled, the
vehicle will no longer be held at a stop.
The vehicle can move. When ACC is
holding the vehicle at a stop, always be
prepared to manually apply the brakes.
{Warning
Leaving the vehicle without placing it in
P (Park) can be dangerous. Do not leave
the vehicle while it is being held at a
stop by ACC. Always place the vehicle in
P (Park) and turn off the ignition before
leaving the vehicle. ACC Override
If using the accelerator pedal while ACC is
active, the ACC indicator turns blue on the
instrument cluster and in the HUD,
if equipped, to indicate that automatic
braking will not occur. ACC will resume
operation when the accelerator pedal is not
being pressed.
{Warning
The ACC will not automatically apply the
brakes if your foot is resting on the
accelerator pedal. You could crash into a
vehicle ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a vehicle
ahead in your lane. You could be startled
if the vehicle accelerates up to the set
speed, especially when following a vehicle
exiting or entering exit ramps. You could
lose control of the vehicle or crash. Do
not use ACC while driving on an entrance
or exit ramp. Always be ready to use the
brakes if necessary.
