stored.
A second seating and mirror position can be
programmed by repeating the above steps and
pressing button 2 for a second driver.To recall your memory positions, the vehicle must
be in PARK (P). Press and release either
button 1 or button 2 corresponding to the desired

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, see
Older Children on page 43orInfants and Young
Children on page 46. 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 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.
25
Page 27 of 496
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.
27
Page 33 of 496
To unlatch the belt, 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
height adjuster to the height that is right for you.
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, press
the release button (A)
and move the height
adjuster to the desired
position. You can move
the height adjuster up
just by pushing up on the
shoulder belt guide.
After you move the height adjuster to where you
want it, try to move it down without pressing
the release button to make sure it has locked into
position.
