Traffic Light and Stop Sign Control
Traffic Lights
When driving with Autosteer or Traffic-Aware Cruise Control engaged, and Traffic Light and Stop Sign Control
enabled, Model Y is designed to respond as follows when approaching intersections controlled by a traffic light:
Type of Traffic Light
98
Vehicle Intended Response
At a solid green traffic light, or at a traffic light that is currently off (not
illuminated), Model Y slows down.
You must confirm that you want to continue through the intersection by pressing
down on the drive stalk or briefly pressing the accelerator pedal. If you don't
confirm, Model Y stops at the red stop line displayed on the touchscreen.
NOTE: Model Y resumes the set cruising speed when it continues through the
intersection, taking into consideration the speed of a vehicle in front of you.
Model Y slows down and comes to a complete stop at the red stop line displayed
on the touchscreen. When you want to continue through the intersection (for
example, the light turns green again, or once Model Y has come to a complete
stop), you must press down on the drive stalk or briefly press the accelerator
pedal.
Model Y slows down and comes to a complete stop at the red stop line displayed
on the touchscreen. When you want to proceed through the intersection (for
example, the light turns green again), you must press down on the drive stalk or
briefly press the accelerator pedal.
NOTE: If the traffic light changes after you've confirmed that you want to proceed
(for example, a green traffic light turns yellow), Model Y may stop instead of
continuing, especially if Model Y determines that it can safely stop before entering
the intersection.
NOTE: Model Y is not designed to proceed through an intersection when the traffic
light is red or if the light turns yellow in situations when there is adequate distance
to safely stop before entering the intersection.
NOTE: You can take over driving at any time by manually braking to cancel
Autosteer or Traffic-aware Cruise Control.
