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 lap belt
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
The center lap belt tongues are designed to fit only in the correct
buckle. The tongue will not securely latch if you attempt to use it in any
of the outboard seating position buckles. To ensure that you have used
the correct buckle you should hear a snap and feel it latch.
• 1st row center and 2nd row center (SuperCab) seating position
The lap belt does not adjust automatically.
