Headlights

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

Trim level(s)

All trims

Distance at which headlights provide at least 5 lux illumination:
Low-beam headlight type	LED projector
High-beam headlight type	LED reflector
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 on the sharp left and both right curves 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.
