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.
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 control for the
power seat is located on the outboard side of each
front seat.
To adjust the power seats, do the following:
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.
Raise or lower the entire seat by holding the whole
control up or down.

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. The word “HI” lights up above
the button. Press the button again for the low setting.
The word “LO” lights up above the button. 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 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.

Q:If I am a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-28
orInfants and Young Children on page 1-31. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is 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.
1-13
Page 20 of 392

3. 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.
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 is not long enough, seeSafety Belt
Extender on page 1-27.
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 would
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 is a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-13.
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.
When you sit in the center front seating position, you
have a lap safety belt, which has no retractor. To make
the belt longer, tilt the latch plate and pull it along
the belt.
1-20
Page 28 of 392
Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts. Here
is how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not 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.If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle it.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-27.
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.
1-22
Page 30 of 392
The safety belt locks if there is a sudden stop or a
crash, or if you pull the belt very quickly out of
the retractor.
{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.
