Reclining the Seatbacks (Yukon Denali 60/40 Split
Bench Only)
To recline the seatback, do the following:
2. Release the lever to lock the seatback where you
want it. Pull the lever again without pushing on
the seatback and the seatback will go to an
upright position.
1. Pull the lever
located at the
base of the seat
cushion forward.
Folding the Seatbacks (60/40 Split Bench Seat)
CAUTION:
If the seatback isn't locked, it could move
forward in a sudden stop or crash. That
could cause injury to the person sitting there.
Always press rearward on the seatback to be
sure it is locked.
The rear seat may have a 60/40 split seat which may be
folded down to create a load floor and give you more
cargo space. On the Yukon Denali, the rear seatbacks are
equipped with rearward folding head restraints. When
the seatback is being folded down, the head restraint will
automatically fold rearward. For the Yukon XL Denali
you must manually pull the headrest forward before
folding the seatback.
