Folding or Reclining the Seatbacks
CAUTION:
{
If the seatback isn't 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.
To recline the seatback, lift up on the recliner lever,
located on the outboard side of the seat. Use the recliner
lever to move the seatback to the desired position.
It is easier to raise or lower the seatback if you
lean forward, taking the weight off the seatback.
The seatbacks on the second row captain's chairs
also fold forward to put items behind the left and
right seats.
Lift up on the recliner lever and fold the seatback
forward. The seatback will lock into place when you
push it back to the upright position.
The armrests can be lowered or raised for entering or
exiting the vehicle.
