Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

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 remained a safe distance from the front seatback.

Rear passenger dummy injury values indicate a low risk of injury to the head or neck and a moderate risk of injury to the 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.

High-beam assist?	Yes
Overall rating

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

The low beams created some glare.

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

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