COMFORT ADJUSTMENT

"Front seat belts only
Adjust the shoulder anchor position to your size.
To raise the anchor position, push the anchor up. To lower the anchor
position, support the anchor while you push the lock release button
then slide the anchor down. After the adjustment, make sure the
anchor is locked in position.
CAUTION
Always make sure the shoulder belt is positioned across the
center of your shoulder. The belt should be kept away from
your neck, but not falling off your shoulder. Failure to do so
could reduce the amount of protection in an accident and
cause severe injuries in a collision.

If the belt does not retract smoothly, pull it out and check for kinks
or twists. Then make sure it remains untwisted as it retracts.
