Model 3 slows down. To proceed, you must press down on the drive stalk or briefly
press the accelerator pedal. If you don't, Model 3 stops at the red stop line
displayed on the touchscreen.
NOTE: To prevent Model 3 from stopping, and to minimize how much it slows down
as it approaches, you can confirm that you want to proceed by pressing down on
the drive stalk or briefly pressing the accelerator pedal at any time after the
touchscreen displays the red stop line. Model 3 resumes your set cruising speed
immediately after you confirm (taking into consideration the speed of a vehicle in
front of you).
WARNING: Approach attentively and be prepared to press the brake pedal to
slow down or stop.
Model 3 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, traffic laws and conditions indicate it is safe and legal to proceed), you
must press down on the drive stalk or briefly press the accelerator pedal.
