Rear passenger restraints and dummy kinematics

View of the vehicle after the crash showing the airbags and damage to the occupant compartment.

The rear passenger dummy's head came close to contacting the front seatback, which increases the risk of head injuries.

Rear passenger dummy injury values indicate a low risk of injury to the head or neck and chest. During the crash, the shoulder belt moved too far upward toward the dummy’s neck, compromising the effectiveness of the rear restraint system.

The rear passenger dummy's lap belt moved from the ideal position on the pelvis onto the abdomen, increasing the risk of abdominal injuries.

Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was fair in all 4 tests.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was fair on the gradual right and gradual left curves and inadequate on the sharp right and sharp left curves.

High-beam assist compensates for some limitations of this vehicle's low beams on both left curves and on both right curves.
