The forward looking camera(s) and the radar sensor are designed to determine the distance from a detected object traveling in front of Model 3. When a frontal collision is considered unavoidable, Automatic Emergency Braking is designed to apply the brakes to reduce the severity of the impact.
When Automatic Emergency Braking applies the brakes, the touchscreen displays a visual warning and sounds a chime. You may also notice abrupt downward movement of the brake pedal. The brake lights turn on to alert other road users that you are slowing down.
If driving 35 mph (56 km/h) or
faster, the
brakes are released after Automatic
Emergency Braking has reduced your driving
speed by 30 mph (50 km/h). For example, if
Automatic Emergency Braking applies braking
when driving 56 mph (90 km/h), it releases
the brakes when your speed has been reduced
to 26 mph (40 km/h).
Automatic Emergency Braking operates only when driving between approximately 7 mph (10 km/h) and 90 mph (150 km/h).
Automatic Emergency Braking does not apply the brakes, or stops applying the brakes, when:
Automatic Emergency Braking is always enabled when you start Model 3. To disable it for your current drive, touch Controls > Autopilot > Automatic Emergency Braking.
Warning: It is strongly recommended that you do not disable Automatic Emergency Braking. If you disable it, Model 3 does not automatically apply the brakes in situations where a collision is considered likely.
Warning: Automatic Emergency Braking is designed to reduce the severity of an impact. It is not designed to avoid a collision.
Warning: Several factors can affect the performance of Automatic Emergency Braking, causing either no braking or inappropriate or untimely braking, such as when a vehicle is partially in the path of travel or there is road debris. It is the driver's responsibility to drive safely and remain in control of the vehicle at all times. Never depend on Automatic Emergency Braking to avoid or reduce the impact of a collision.
Warning: Automatic Emergency Braking is designed to reduce the impact of frontal collisions only and does not function when Model 3 is in Reverse.
Warning: Automatic Emergency Braking is not a substitute for maintaining a safe traveling distance between you and the vehicle in front of you.
Warning: The brake pedal moves downward abruptly during automatic braking events. Always ensure that the brake pedal can move freely. Do not place material under or on top of the Teslasupplied driver's floor mat (including an additional mat) and always ensure that the driver's floor mat is properly secured.
Failure to do so can impede the ability of the brake pedal to move freely.
