A camera mounted between the windshield and the rearview mirror determines if your vehicle begins to cross over detected lane markings while driving between 45–90 mph (72–145 km/h).

If you get too close to a detected lane line without using your turn signal, a message appears in the MID.

Steering wheel torque and vibrations are applied to help your vehicle stay in the lane. Braking may also be applied if the lane lines are solid and continuous.
