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.
If your vehicle has manual seats, lift the 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 back and forth to be sure the seat is locked
in place.

Heated Seats
If your vehicle has this option, the driver’s and
passenger’s heated seat switches are located on the
outboard side of the seat.
Press LO to warm the seat to a lower temperature.
Press HI to warm the seat to a higher temperature.
To turn this feature off, move the switch to the
center position.
Reclining Seatbacks
Lift the lever to release the seatback, then move the
seatback to where you want it. Release the lever to lock
the seatback in place. Pull up on the lever without
pushing on the seatback and the seatback will move
forward.

To raise the rear seatback, follow these steps:
1. Raise the seatback up and make sure it latches.
2. Push and pull on the seatback to be sure it is locked
in position.
3. Ensure that the safety belts are properly stowed
over the seatback in all three positions.
{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
press rearward on the seatback to be sure it is
locked.
When the seat is not in use, it should be kept in the
upright locked 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 1-29
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 398
3. 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.
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 1-28.
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.5. Move the shoulder belt height adjuster to the height
that is right for you. SeeShoulder Belt Height
Adjustment on page 1-20.
6. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
1-14
Page 21 of 398
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.
1-15
Page 26 of 398
To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
To move it down, squeeze the release lever (A) and the
shoulder belt guide as shown 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
release lever to make sure it has locked into 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.
