Reclining Seatbacks
The vertical power seat control described earlier allows
the seatback to recline.
But do not 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 not do their
job when you are reclined like this.
The shoulder belt can not do its job. In a
crash, you could go into it, receiving neck or
other injuries.
The lap belt can not 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.

3. Pull (push if you are exiting the third row with no
assistance) the seat forward until it stops.
{CAUTION:
If the seatback is not 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.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.Be sure to return the seat to the passenger position
when nished. Pull forward and push rearward on the
seat to make sure it is locked in place.
Heated Seats
The buttons used to control
this feature are located on
the back of the center
console. The engine must
be running for the heated
seat feature to work.
To heat the seat, press the button to cycle through the
temperature settings of high and low. Press the
button a third time to turn the seats off. An Indicator
light will glow for each heat setting when the seats are
operating.
The heated rear seats will shut off automatically when
the ignition is turned off.
