the restraint is at the same height as the
top of the occupant's head. This position
reduces the chance of a neck injury in a
crash.
The height of the head restraint can be
adjusted. Pull the head restraint up to raise
it. Try to move the head restraint to make
sure that it is locked in place.
To lower the head restraint, press the
button, located on the top of the seatback,

to fold the seatback down.
The head restraint can be folded forward to
allow for better visibility when the rear seat
is unoccupied. To fold the head restraint,
press the button on the side of the head
restraint.
When an occupant is in the seat, always
return the head restraint to the upright
position until it locks into place. Push and
pull on the head restraint to make sure that
it is locked.

Reclining Seatbacks
{Warning
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the seat belts
cannot do their job.
The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.
For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.
Do not have a seatback reclined if the
vehicle is moving.
{Warning

try to adjust a driver seat while the
vehicle is moving. Adjust the driver seat
only when the vehicle is not moving.

That could cause injury to the person
sitting there. Always push and pull on
the seatbacks to be sure they are locked.
To recline the seatback:1. Lift the lever.
2. Move the seatback to the desired position, and then release the lever to

Heated and Ventilated Front
Seats
{Warning
If temperature change or pain to the skin
cannot be felt, the seat heater may cause
burns. To reduce the risk of burns, use
care when using the seat heater,
especially for long periods of time. Do
not place anything on the seat that
insulates against heat, such as a blanket,
cushion, cover, or similar item. This may
cause the seat heater to overheat. An
overheated seat heater may cause a burn
or may damage the seat.
If equipped, the buttons are on the center
stack. To operate, the engine must be
running.
If equipped, press
+to heat the driver or

The indicator light on the button comes on
when this feature is on.
Press the button once for the highest
setting. With each press of the button, the
seat will change to the next lower setting,
and then to the off setting. The indicator
lights next to the buttons indicate three for
the highest setting and one for the lowest.
If the heated seats are on high for an
extended time, their level may automatically
be lowered.

on during a remote start unless they are
enabled in the vehicle personalization menu.
Rear Seats
Rear Seat Reminder
If equipped, the message REAR SEAT
REMINDER LOOK IN REAR SEAT displays
under certain conditions indicating there
may be an item or passenger in the rear
seat. Check before exiting the vehicle.

door is opened while the vehicle is on or up
to 10 minutes before the vehicle is turned
on. There will be an alert when the vehicle

GMC Canyon/Canyon Denali Owner Manual (GMNA-Localizing-U.S./Canada-
14430430) - 2021 - CRC - 9/9/20
26 Seats and Restraints
is turned off. The alert does not directly
detect objects in the rear seat; instead,
under certain conditions, it detects when a
rear door is opened and closed, indicating
that there may be something in the
rear seat.
The feature is active only once each time
the vehicle is turned on and off, and will
require reactivation by opening and closing
the second row doors. There may be an
alert even when there is nothing in the rear
seat; for example, if a child entered the
vehicle through the rear door and left the
vehicle without the vehicle being shut off.
The feature can be turned on or off. See
Vehicle Personalization099.
Folding the Rear Seat
On crew cab models, the rear seatbacks can
be folded forward.
Caution
Folding a rear seat with the seat belts
still fastened may cause damage to the
seat or the seat belts. Always unbuckle
the seat belts and return them to their
normal stowed position before folding a
rear seat. To fold a rear seatback:
1. Fold the head restraint. See Head
Restraints 021.
2. Disconnect the rear center seat belt latch
from the mini-buckle by inserting the tip
of the seat belt tongue into the slot on
the buckle. Let the belt retract.
3. Pull the release strap on the outboardside of the seatback.
4. Fold the seatback forward.
To return a seatback to the upright position: 1. Lift the seatback up and push it rearward.
2. Return the head restraint to the upright position. See Head Restraints 021.
{Warning
If either seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on
the seatbacks to be sure they are locked.

14430430) - 2021 - CRC - 9/9/20
Seats and Restraints 27
3. Push and pull on the seatback to makesure it is locked in place.
{Warning
A seat belt that is improperly routed, not
properly attached, or twisted will not
provide the protection needed in a crash.
The person wearing the belt could be
seriously injured. After raising the rear
seatback, always check to be sure that
the seat belts are properly routed and
attached, and are not twisted.
4. Reconnect the center seat belt latch plate to the mini-buckle. Make sure the
seat belt is not twisted.
5. Push and pull on the latch plate to be sure it is secure.
When the seatback is not in use, it should
be kept in the upright, locked position.
Seat Belts
This section describes how to use seat belts
properly, and some things not to do.
{Warning
Do not let anyone ride where a seat belt
cannot be worn properly. In a crash,
if you or your passenger(s) are not
wearing seat belts, injuries can be much
worse than if you are wearing seat belts.
You can be seriously injured or killed by
hitting things inside the vehicle harder or
by being ejected from the vehicle. In
addition, anyone who is not buckled up
can strike other passengers in the vehicle.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, passengers riding in these
areas are more likely to be seriously
injured or killed. Do not allow passengers
to ride in any area of the vehicle that is
not equipped with seats and seat belts.
Always wear a seat belt, and check that
all passenger(s) are restrained
properly too.
This vehicle has indicators as a reminder to
buckle the seat belts. See Seat Belt
Reminders 085.
Why Seat Belts Work
When riding in a vehicle, you travel as fast
as the vehicle does. If the vehicle stops
suddenly, you keep going until something
stops you. It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and the
vehicle slow down together. There is more
time to stop because you stop over a longer
distance and, when worn properly, your
strongest bones take the forces from the
seat belts. That is why wearing seat belts
makes such good sense.
