Front Seats
Manual Seats
{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 do not want to. Adjust the driver’s
seat only when the vehicle is not moving.To move a manual seat forward or rearward:
1. Lift the bar to unlock
the seat.
2. Slide the seat to the
desired position and
release the bar.
Try to move the seat with your body to be sure the seat
is locked in place.
1-2

If you use the remote keyless entry transmitter to enter
your vehicle and the remote recall memory feature
is on, automatic seat, adjustable mirror, and adjustable
pedal movements will occur. See “MEMORY SEAT
RECALL” underDIC Vehicle Customization (With DIC
Buttons) on page 3-66for more information.
To stop recall movement of the memory function at any
time, press one of the power seat controls, memory
buttons, power mirror buttons, or adjustable pedal
switch.
If something has blocked the driver’s seat and/or the
adjustable pedals while recalling a memory position, the
driver’s seat and/or the adjustable pedals recall may
stop working. If this happens, remove the obstruction
and press the appropriate control for the area that is not
responding for two seconds. Try recalling the memory
position again by pressing the appropriate memory
button. If the memory position is still not recalling, see
your dealer for service.Easy Exit Seat
The control for this feature is located on the driver’s
door panel between buttons 1 and 2.
With the vehicle in PARK (P), the driver’s seat exit
position can be recalled by pressing the exit button.
You will hear a single beep, and the driver’s seat
will move back.
If the easy exit seat feature is programmed in the Driver
Information Center (DIC), automatic seat movement
will occur when the key is removed from the ignition.
See “EASY EXIT SEAT” underDIC Vehicle
Customization (With DIC Buttons) on page 3-66for
more information.
The memory seat and easy exit features can also be
programmed using the DIC.
For programming information, seeDIC Vehicle
Customization (With DIC Buttons) on page 3-66.

Reclining Seatbacks
{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 do not want to. Adjust the driver’s
seat only when the vehicle is not moving.
{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
push and pull on the seatback to be sure it is
locked.
1-8

{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot 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.
Manual Reclining Seatbacks
On seats with manual reclining seatbacks, the lever
used to operate them is located on the outboard side of
the seat(s).
To recline the seatback:
1. Lift the recline lever.
2. Move the seatback to the desired position, then
release the lever to lock the seatback in place.
3. Push and pull on the seatback to make sure
it is locked.
1-9

To return the seatback to an upright position, do the
following:
1. Lift the lever fully without applying pressure to the
seatback and the seatback will return to the upright
position.
2. Push and pull on the seatback to make sure it is
locked.Power Reclining Seatbacks
If the seats have power reclining seatbacks, the control
used to recline them is located on the outboard side
of the seat behind the power seat control.
To recline the seatback, tilt the top of the control
rearward.
To bring the seatback forward, tilt the top of the
control forward.
Do not have a seatback reclined if your vehicle is
moving.
1-10

{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.
{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
be sure to press the rear of the seat cushion
down. This action locks the seatback in place.
Push and pull on the seatback to make sure it is locked.
Raise the head restraint.
1-13

Sit up straight and always keep your feet on the oor
in front of you. The lap part of the belt should be
worn low and snug on the hips, just touching the thighs.In a crash, this applies force to the strong pelvic bones
and you would be less likely to slide under the lap
belt. If you slid under it, the belt would apply force on
your abdomen. This could cause serious or even
fatal injuries. The shoulder belt should go over the
shoulder and across the chest. These parts of the body
are best able to take belt restraining forces.
The shoulder belt locks if there is a sudden stop
or crash.
1-20

Lap-Shoulder Belt
All seating positions in your vehicle have a lap-shoulder
belt except for the center front passenger position (if
equipped), which has a lap belt. SeeLap Belt on
page 1-34for more information.
Here is how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you
can sit up straight. To see how, see “Seats” in
the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let the
belt go back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system. See
Passenger Sensing System on page 1-69.3. Push the latch plate into the buckle until it clicks.
If you nd that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-35.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
1-28

Shoulder Belt Height Adjuster
Your vehicle has a shoulder belt height adjuster for the
driver and right front passenger position.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be
away from your face and neck, but not falling off your
shoulder. Improper shoulder belt height adjustment
could reduce the effectiveness of the safety belt
in a crash.
To move it down, squeeze
the buttons (A) on the
sides of the height adjuster
and move the height
adjuster to the desired
position.
You can move the adjuster up just by pushing up on the
shoulder belt guide.
After you move the adjuster to where you want it, try to
move it down without squeezing the buttons to make
sure it has locked into position.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for front
outboard occupants. Although you cannot see them,
they are part of the safety belt assembly. They can help
tighten the safety belts during the early stages of a
moderate to severe frontal, near frontal, or rear crash if
the threshold conditions for pretensioner activation
are met. And, if your vehicle has side impact airbags,
safety belt pretensioners can help tighten the safety
belts in a side crash or a rollover event.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-77.
