injury or even fatal injury.
Always keep the seat belt of the activated
special seat belt retractor engaged when
driving.
With the exception of the driver's seat belt
and the seat belts on the folding bench seat
in the cargo compartment, all seat belts in the
vehicle are equipped with a special seat belt

belt retractor.
X Engage the seat belt tongue in the belt
buckle.
