Braking and Stopping
WARNING: Always maintain a safe distance from
the vehicle in front of you and be aware of
hazardous driving conditions. While the ABS can
improve stopping distance, it cannot overcome the
laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of water
prevents direct contact between the tires and the
road).
Braking Systems
WARNING: Properly functioning braking systems
are critical to ensure safety. If you experience a
problem with the brake pedal, brake calipers, or
any component of a Model Y braking system,
contact Tesla immediately.
CAUTION: Automatic Emergency Braking (see
Automatic Emergency Braking on page 123) may
intervene to automatically brake in situations
where a collision is considered imminent.
Automatic Emergency Braking is not designed to
prevent a collision. At best, it can minimize the
impact of a frontal collision by attempting to
reduce your driving speed. Depending on
Automatic Emergency Braking to avoid a collision
can result in serious injury or death.
Model Y has an anti-lock braking system (ABS) that
prevents the wheels from locking when you apply
maximum brake pressure. This improves steering control
during heavy braking in most road conditions.
During emergency braking conditions, the ABS
constantly monitors the speed of each wheel and varies
the brake pressure according to the grip available.
The alteration of brake pressure can be felt as a pulsing
sensation through the brake pedal. This demonstrates
that the ABS is operating and is not a cause for concern.
Keep firm and steady pressure on the brake pedal while
experiencing the pulsing.
CAUTION: In emergency situations, if the brakes
are not functioning properly, press and hold the
Park button on the drive stalk to bring the vehicle
to a stop. Do not use this method to stop the
vehicle unless absolutely necessary.
The ABS indicator briefly flashes amber on
the touchscreen when you first start Model
Y. If this indicator lights up at any other
time, an ABS fault has occurred and the
ABS is not operating. Contact Tesla. The
braking system remains fully operational
and is not affected by an ABS failure.
However, braking distances may increase.
Drive cautiously and avoid heavy braking.
Dynamic Brake Lights (if equipped)
If you are driving over 30 mph (50 km/h) and brake
forcefully (or if Automatic Emergency Braking engages),
the brake lights flash quickly to warn other drivers that
Model Y is rapidly slowing down. If Model Y stops
completely, the hazard warning lights flash. Flashing
continues until you press the accelerator or manually
press the hazard lights button to turn them off (see
Hazard Warning Flashers on page 60).
If the touchscreen displays this red brake
indicator at any time other than briefly
when you first start Model Y, a brake
system fault is detected, or the level of the
brake fluid is low. Contact Tesla
NOTE: Dynamic brake lights will not flash while Track
Mode is enabled (see Track Mode on page 74).
immediately. Apply steady pressure and
keep the brakes firm to bring the vehicle to
a stop when safe to do so.
NOTE: When towing a trailer (if applicable), the brake
lights on the trailer also operate as described above,
even when the trailer is not equipped with a separate
braking system.
The touchscreen displays this amber brake
indicator if a brake booster fault is
detected. Apply steady pressure and keep
the brakes firm to stop the vehicle when
safety permits. Hydraulic Boost
WARNING: When towing a trailer (if applicable),
always increase your following distance. Sudden
braking may result in skidding, jack-knifing, and
loss of control.
Compensation will be active (see Hydraulic
Boost Compensation on page 66).
Brake Disc Wiping
Emergency Braking
To ensure brakes remain responsive in cold and wet
weather, Model Y is equipped with brake disc wiping.
When cold and wet weather is detected, this feature
repeatedly applies an imperceptible amount of brake
force to remove water from the surface of the brake
discs.
In an emergency, fully press the brake pedal and
maintain firm pressure, even on low traction surfaces.
The ABS varies the braking pressure to each wheel
according to the amount of traction available. This
prevents wheels from locking and ensures that you stop
as safely as possible.
WARNING: Do not pump the brake pedal. Doing so
interrupts operation of the ABS and can increase
braking distance.
