Head Restraints

adjustable head restraints in the
outboard seating positions.
{Warning
With head restraints that are not
installed and adjusted properly,

occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.The height of the head restraint can
be adjusted. Pull the head restraint
up to raise it. Try to move the head
restraint to make sure that it is
locked in place.
To lower the head restraint, press

restraint down. Try to move the
head restraint after the button is
released to make sure that it is
locked in place.

{Warning
Sitting in a reclined position when

against your body. Instead, it will
be in front of you. In a crash, you
could go into it, receiving neck or
other injuries.
The lap belt could go up over
your abdomen. The belt forces
would be there, not at your pelvic
bones. This could cause serious
internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
seat belt properly.
Do not have a seatback reclined if
the vehicle is moving.

If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
