Automatic Emergency Braking with Autopilot Tesla Model Y

The forward-looking camera(s) and radar sensor are used to calculate the distance between Model Y and a detected object moving in front of it. Automatic Emergency Braking is designed to apply the brakes to decrease the severity of a frontal accident when it is deemed unavoidable.

The touchscreen displays a visual warning and sounds a whistle when Automatic Emergency Braking applies the brakes. You can also notice the brake pedal moving down abruptly. The brake lights illuminate to signal to other drivers that you are slowing down.

See Collision Avoidance Assist and Autopilot Overview and Features.

The brakes are released once Automatic Emergency Braking has lowered your driving speed by 30 mph (50 km/h) or more if you're going 35 mph (56 km/h) or faster. Automatic Emergency Braking, for example, applies braking when travelling 56 mph (90 km/h) and then releases the brakes when your speed drops to 26 mph (40 km/h).

Only when driving between 7 mph (10 km/h) and 90 mph (150 km/h) does Automatic Emergency Braking activate.

When you turn the steering wheel sharply, Automatic Emergency Braking does not apply the brakes or stops applying the brakes.

  • While Automatic Emergency Braking applies the brakes, you push and release the brake pedal.
  • You accelerate quickly while the brakes are applied by Automatic Emergency Braking.
  • There is no longer a car, motorbike, bicycle, or pedestrian detected ahead.

When you start Model Y, Automatic Emergency Braking is always on. Touch Controls > Autopilot > Automatic Emergency Braking to turn it off for the current drive.

WARNING: It is strongly advised that you should not turn off Automatic Emergency Braking. If you turn it off, Model Y will not use the brakes automatically in circumstances when a collision is expected.

WARNING: The purpose of automatic emergency braking is to lessen the severity of a crash. It isn't built to prevent colliding with anything.

WARNING: When a vehicle is partially in the course of travel or there is road debris, several variables can impact the performance of Automatic Emergency Braking, resulting in no braking or improper or late braking. The driver is responsible for driving safely and maintaining vehicle control at all times. Never rely on Automatic Emergency Braking to prevent or mitigate a crash.

WARNING: When the Model Y is in reverse, Automatic Emergency Braking is only meant to mitigate the effect of frontal collisions.

WARNING: Warning: Automatic Emergency Braking is not a replacement for keeping a safe following distance from the car in front of you. During automated braking events, the brake pedal goes downward abruptly. Always make sure the brake pedal is free to move. Place no material (including a second mat) under or on top of the Tesla-supplied driver's floor mat, and always make sure it is properly secured. Failure to do so may obstruct the brake pedal's ability to move freely.
