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 don’t want to. Adjust the driver’s
seat only when the vehicle is not moving.
Pull up on the control bar located under the front of the
seat to unlock it. Slide the seat to where you want it
and release the bar. Try to move the seat with your body
to make sure the seat is locked into place.
Power Seats
If your vehicle has this feature, the controls for the power
seats are located on the outboard side of each front seat.
To adjust the power seats, do the following:
Horizontal Control:Raise or lower the front of the seat
cushion by pressing the forward edge of the control
up or down.
Raise or lower the rear of the seat cushion by pressing
the rear edge of the control up or down.
Move the seat forward or rearward by pressing the
control toward the front or rear of the vehicle.
Move the seat higher or lower by holding the whole
control up or down.

If you have the independent front cushion moved down
as far as it will go, you may feel the lumbar support
higher in your back. Readjust the location of the cushion
until you are comfortable. You may also want to
adjust the seatback for maximum comfort.
Heated Seats
If your vehicle has this feature, press this button to turn
on the heating element in the seat.
The heated seat buttons
are located on the driver’s
and front passenger’s
door panel.
When the heated seat button is rst pressed, the high
setting is activated. Press the button again for the
low setting. The third press of the button turns the
feature off.The low setting warms the seatback and cushion until
the seat nears body temperature. The high setting heats
the seat to a slightly higher temperature.
The heated seats can be used only while the ignition is
turned on. When the ignition is turned off, the heating
element is also turned off.Reclining Seatbacks
If your vehicle has power
seats, the vertical control
described previously in this
section reclines the front
seatbacks.
If your vehicle has the manual recliner, lift the lever on
the outboard side of the seat and move the seatback to
the desired position. Release the lever to lock the
seatback. Pull up on the lever without pushing on the
seatback and the seatback will go to an upright position.

Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Don’t 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.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn’t long enough, seeSafety Belt
Extender on page 1-26.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

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’d be
less likely to slide under the lap belt. If you slid under it,
the belt would apply force at 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 safety belt locks if there’s a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-12.
The right front passenger’s safety belt works the same
way as the driver’s safety belt – except for one thing.
If you ever pull the lap portion of the belt out all the way,
you will engage the child restraint locking feature. If
this happens, just let the belt go back all the way and
start again.
If your vehicle has a center passenger position, be sure
to use the correct buckle when buckling your
lap-shoulder belt. If you nd that the latch plate will not
go fully into the buckle, see if you are using the
buckle for the center passenger position.
Center Front Passenger Position
Lap Belt
If your vehicle has a front bench seat, someone can sit
in the center position.

Rear Seat Passengers
It’s very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in the
rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who aren’t safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts. Here’s
how to wear one properly.1. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
The 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.
2. Push the latch plate into the buckle until it clicks.

{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should t against your body.
To unlatch the belt, just push the button on the buckle.
