The rear drive wheels may rotate during some of the following tests. Block the
front wheels, raise the rear drive wheels off the ground, and support the vehicle
with jack stands. Failure to do so may cause the vehicle to move and cause
severe bodily injury and/or property damage.
Rotating rear drive wheels are a potential hazard. Keep hands, arms, legs and
loose clothing away from the rear drive wheels while conducting tests. Failure
to do so may cause serious bodily injury.
