Reclining Seatbacks - GMC Yukon Denali 2003 Owner's Manual

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.
Your vehicle also has rear heated seats. See Heated
Seats on page 1-8 .

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.
