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.

Headlights

Ratings are given for 2 different headlight variations available on this vehicle.

Trim level(s)

  • All trims equipped with Premium Triple Beam Headlights package
Low-beam headlight type LED projector
High-beam headlight type LED projector
Curve-adaptive? No
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 in all 4 tests.

The low beams never exceeded glare limits.

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

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