Reclining Seatbacks
Power Reclining Seatbacks
Driver Seat with Power Seat
Control, Power Recline,
and Power Lumbar Shown
The controls for the power reclining
seatback are located on the
outboard side of the front seats
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.
WARNING
Sitting in a reclined position when
your vehicle is in motion can be
dangerous. Even if you buckle up,
your safety belts cannot do their
job when you are reclined
like this.
WARNING (Continued)
The shoulder belt cannot do its
job. In a crash, you could go into
it, receiving neck or other injuries.
The lap belt cannot 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.
Your vehicle has a memory function
which allows seat settings to be
saved and recalled. See Power
Seat Adjustment on page 3 3.
