Headlights

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

Trim level(s)

  • Pinnacle trim
Low-beam headlight type LED projector
High-beam headlight type LED projector
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 good on both sides of the road. On curves, visibility was good on the sharp left and sharp right curves and fair on the gradual left and gradual right curves.

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 in all 4 tests.

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

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 created some glare.

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 right and gradual left 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 both left curves and on both right curves.
