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

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

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

The low beams created some glare.

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 gradual left and sharp right 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.
