Failure to follow these instructions will affect the performance of
the safety belts and increase the risk of personal injury.
Safety belt pretensioner (if equipped)
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The Seat Integrated Restraints (SIR) seat is equipped with a buckle
pretensioner. Do NOT place objects between the seats, this could
interfere with the functioning of the pretensioner.
The safety belt pretensioners are designed to activate only during certain
frontal or near-frontal collisions with sufficient longitudinal deceleration.
A safety belt pretensioner is a device which tightens the webbing of the
lap and shoulder belts in such a way that they fit more snugly against
the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to the Safety belt maintenance section in this
chapter.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, front
passenger and second row outboard
passengers. 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 down 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.
