2004 Pontiac Bonneville Owner ManualM

To adjust the power seats, do the following:
Horizontal Control:Raise or lower the front of the seat
cushion by pressing the forward edge of the control
up or down.
Raise or lower the rear of the seat cushion by pressing
the rear edge of the control up or down.
Move the seat forward or rearward by pressing the
control toward the front or rear of the vehicle.
Move the seat higher or lower by holding the whole
control up or down.
Vertical Control (Option):Adjust the angle of the
seatback by pressing the top of the control forward or
rearward.Manual Lumbar
The knob that controls this feature is located on the
outboard side of each front seat. Turn the knob toward
the front of the vehicle to increase lumbar support.
Turn the knob toward the rear of the vehicle to decrease
lumbar support.
If you have the independent front cushion moved down
as far as it will go, you may feel the lumbar support
higher in your back. Readjust the location of the cushion
until you are comfortable. You may also want to
adjust the seatback for maximum comfort.

Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a seat next to a window, move
the child toward the center of the vehicle. If the child
is sitting in the center rear seat passenger position,
move the child toward the safety belt buckle. In either
case, be sure that the shoulder belt still is on the
child’s shoulder, so that in a crash the child’s upper
body would have the restraint that belts provide.
{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the belt in
this way, in a crash the child might slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious or fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that’s
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.
Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.
