Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Front safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver and front
passenger. Adjust the height of the
shoulder belt so the belt rests
across the middle of your shoulder.
To lower the shoulder belt height,
push the button and slide the height
adjuster down. To raise the height
of the shoulder belt, slide the height
adjuster up. Pull down on the height
adjuster to make sure it is locked in
place.
Position the safety belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.
Lap belts
Adjusting the center lap belt
The lap belt does not adjust automatically.
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
