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.

Although intrusion into the driver's space was minimal, forces on the dummy's right lower leg were high enough to indicate a significant risk of injury.

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.

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

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 good on both right curves and fair on both left curves.

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