Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
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.
If your vehicle has a manual bucket or split bench seat,
you can adjust it with this lever located at the front of
the seat.
Lift the lever at the front of the seat to unlock it. Using
your body, slide the seat to where you want it. Then,
release the lever and try to move the seat with your body
in order to make sure the seat is locked into place.

1-3
Manual Cushion Tilt (If Equipped)
If your vehicle has this feature, you can raise or lower
the front of the driver's or passenger's seat with this
lever located at the inside edge of the seat. To raise or
lower the front of the seat, move the lever up or down
in a continuous motion until the cushion reaches the
desired height.
Manual Lumbar Control (If Equipped)
If your vehicle has a
lumbar adjustment,
you can increase or
decrease lumbar support
in an area of the lower
seatback. The control is
located on the outboard
side of the front seats.
To increase support, turn the knob towards the front of
the vehicle. Operating effort can be reduced if you lean
forward slightly while turning the knob.
To decrease support, turn the knob towards the rear of
the vehicle.

1-4 Power Seat(s) (If Equipped)
Horizontal Control: If your vehicle has a power seat,
you can adjust it with these controls located at the
outboard edges of the seats.Raise or lower the front of the seat cushion by raising or
lowering the forward edge of the button.
Move the seat forward or rearward by moving the whole
button forward or rearward.
Raise or lower the rear of the seat cushion by raising or
lowering the rear edge of the button.
Moving the whole button up or down raises or lowers
the entire seat cushion.
Vertical Control: If your vehicle has the power
reclining seats, you can use this button to adjust the
angle of the seatback. Move the reclining front seatback
rearward or forward by moving this button toward the
rear or the front of the vehicle. See ªReclining
Seatbacksº in the Index for further information.

1-5 Power Lumbar Control (If Equipped)
To increase or decrease
support, press and hold the
front or rear of the control.
Let go of the control when
the lower seatback reaches
the desired level of support.
You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase or decrease support, press and hold the top
or bottom of the control. Let go of the control when the
lower seatback reaches the desired level of support.
Memory Seat (If Equipped)
The memory function
controls the driver's
seat cushion and recliner
positions and is located
on the driver's door
trim panel.
It does not store the lumbar or back support positions.
To set your memory seat, do the following:
1. Adjust the driver's seat to your desired position.
2. Press the SET button and then press the 1 or 2
side of the memory control within five seconds.
When your vehicle is in PARK (P), press the 1 or 2
button of the memory control to recall the seat setting.
To do the same thing for a second driver, follow the
preceding steps, but press the other number of the
memory control. The memory feature only works when
the transmission is in PARK (P).

1-6 Heated Front Seats (If Equipped)
If your vehicle has heated
front seats, the ignition
must be in RUN for them
to operate.
The control for the driver's side heated seat is located on the
driver's side door panel. The control for the passenger's side
heated seat is located on the passenger's side door panel.
To activate the heated seats, press the button once for the HI
heat setting. Press the button again for the LO heat setting.
To turn off the heated seats, press the button a third time.
An indicator light on the button will illuminate for each heat
setting anytime the heated seats are operating.
The heated front seats will be canceled after the ignition
is turned to OFF. If you still want to use the heated front
seat feature after you restart your vehicle, you will need
to press the heated seat button again.
Reclining Seatbacks
To adjust the front seatback, lift the lever located on the
outboard side of the seat. Release the lever to lock the
seatback where you want it. Lift the lever again upward
and the seatback will go to an upright position.
If your vehicle has power seats with a power recliner,
see ªPower Seatsº in the Index for further information
on how to operate the reclining seatback feature.

1-7
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.
