But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or

Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle is
moving. The sudden movement could startle and
confuse you, or make you push a pedal when you
don't want to. Adjust the driver's seat only when
the vehicle is not moving.
Move the lever under the front of the manual seat up to
unlock it. Slide the seat to where you want it. Then
release the lever and try to move the seat with your body
to make sure the seat is locked into place.

1-3 Manual Lumbar Support (If Equipped)
If you have this feature,
there will be a knob on the
outside of the driver and
passenger bucket seats.
Turn the knob toward the front of the vehicle to increase
lumbar support and toward the rear of the vehicle to
decrease lumbar support.
Reclining Seatbacks
(Bucket Seats or 60/40 Bench)
To adjust the front seatback,
lift the lever on the outer
side of the seat.
Release the lever to lock the seatback where you
want it. Pull up on the lever and the seat will go to an
upright position.
