2010 GMC SIERRA fold seats

Power Reclining Seatbacks
If the seats have power reclining seatbacks, the control
used to recline them is located on the outboard side of
the seat behind the power seat control.
.To recline the seatback, tilt the top of the control
rearward.
.To bring the seatback forward, tilt the top of the
control forward.
Do not have a seatback reclined if your vehicle is
moving.
Seatback Latches
The front seatbacks tilt forward to allow access to the
rear of the cab.
To tilt the seatback forward, lift the lever located on the
outboard side of the seat cushion.
{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.
To return the seatback to the upright position, push the
seatback rearward until it latches. After returning the
seatback to its upright position, push and pull on the
seatback to make sure it is locked.
Center Seat
Your vehicle may have a front center seat. The
seatback doubles as an armrest and cupholder/storage
area for the driver and passenger when the center seat
is not used. Do not use it as a seating position when the
seatback is folded down.

There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving“ underOff-Road
Driving
on page 5‑11.
Two-Tiered Loading
Depending on the model of your pick‐up, you
can create an upper load platform by positioning
two or four 2 inches (5 cm) by 6 inches (15 cm)
wooden planks across the width of the pickup box.
The planks must be inserted in the pickup box
depressions. The length of the planks must allow
for at least a 3/4 inch (2 cm) bearing surface on
each end of the plank.
When using this upper load platform, be sure
the load is securely tied down to prevent it from
shifting. The load's center of gravity should be
positioned in a zone over the rear axle. The zone
is located in the area between the front of each
wheel well and the rear of each wheel well. The
center of gravity height must not extend above the
top of the pickup box flareboard.
Any load that extends beyond the vehicle's
taillamp area must be properly marked according
to local laws and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
