Heated Seats
The buttons used to
control this feature are

running for the heated seat
feature to work.

low and to turn the heated seat off. Indicator lights
will glow to designate the level of heat selected, three
for high, two for medium, and one for low.

To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.
Reclining Seatbacks
The vertical power seat control described earlier allows
the seatback to recline.
But don't have a seatback reclined if your vehicle is
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can't do their job
when you're reclined like this.
The shoulder belt can't do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can't do its job either. In a crash
the 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 your safety belt
properly.

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.The head restraints tilt forward and rearward also.
To adjust the tilt for either of the front head restraints,
pull it toward you until you hear a click. There are
four positions available: initial position, ®rst click, second
click and third click. Each position will click into place.
After the third position (three clicks) is reached,
pulling the head restraint farther will release it back to
the upright position.
Pull ®rmly on the top of the head restraint to position it
to your liking.
The rear seat head restraints in your vehicle are
adjustable. Slide an adjustable head restraint up or
down so that the top of the restraint is closest to the top
of your head. This position reduces the chance of a
neck injury in a crash.
On some models, the head restraints tilt forward and
rearward also.

folded to give you more cargo space.
Folding the Seatbacks (60/40 Split
Bench Seat)

folded down to create a load ¯oor and give you more
cargo space. On the Yukon Denali, the rear seatbacks
are equipped with rearward folding head restraints.
