{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle

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.
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 with your body

Manual Lumbar
If your vehicle has this
feature, there is a knob

The control is located

so should the position of your lumbar support.
Adjust the seat as needed.

Head Restraints

tab located on the top of the seatback.

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 1-31
orInfants and Young Children on page 1-34. 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.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 1-30.
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.
1-18

5. To make the lap part tight, pull up on the
shoulder belt.
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.
