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 reasonably well.
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.
Footrest, parking brake, and instrument panel intrusion contributed to a significant risk of injury to the left lower leg.

Headlights
Ratings are given for 4 different headlight variations available on this vehicle.
Trim level(s)
- Premium trim equipped with Technology package; built after October 2015
- S trim equipped with Technology package; built after October 2015
| Low-beam headlight type | LED projector |
|---|---|
| High-beam headlight type | LED reflector |
| Curve-adaptive? | Yes |
| High-beam assist? | Yes |
|
Overall rating | |
| Distance at which headlights provide at least 5 lux illumination: | |
Low beams
On the straightaway, visibility was fair on the left side of the road and inadequate on the right side. 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 the right side of the road and inadequate on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and gradual left curves, and inadequate on the sharp left curve.
High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
