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.
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.
NOTE: Depending on location of manufacture, vehicles in
Mexico may show either the text or icon of the brake, ABS,
and park indicator lights.
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.
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 immediately. Keep the brakes
pressed firmly to bring the vehicle to a stop
when safe to do so.
The touchscreen displays this amber brake
indicator if a brake booster fault is detected or
regenerative braking is unavailable (see
Regenerative Braking on page 82). Keep the
brakes pressed firmly to bring the vehicle to a
stop when safe to do so. Hydraulic Boost
Compensation may be active (see Hydraulic
Boost Compensation on page 82).
Emergency Braking
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.
If an alternative method is needed to bring the vehicle to a
stop, press and hold the Park button on the touchscreen's
drive mode strip to apply the brakes and remove drive torque
while the button is held. Swipe from the edge of the
touchscreen towards the passenger, to bring up the drive
mode strip.
WARNING:
Do not pump the brake pedal. Doing so
interrupts operation of the ABS and can increase
braking distance.
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).
CAUTION:
Automatic Emergency Braking (see Collision
Avoidance Assist on page 120) 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.
CAUTION:
In emergency situations, if the brakes are
not functioning properly, press and hold the Park
button on the overhead console or touchscreen to
bring Model Y to a stop. Do not use this method to
stop the vehicle unless absolutely necessary.
Brake Disc Wiping
To ensure brakes remain responsive in cold or wet weather,
Model Y is equipped with brake disc wiping. When cold or
wet weather is detected, this feature repeatedly applies an
imperceptible amount of brake force to remove water from
the surface of the brake discs.
Hydraulic Fade Compensation
Model Y is equipped with hydraulic fade compensation. This
assists in monitoring brake system pressure and ABS activity
for instances of reduced brake performance. If reduced brake
performance is detected (for example, as a result of brake
fade, or cold or wet conditions), you may hear a sound and
notice a strong increase in braking. Brake as you normally
would and continue to press the brake pedal without
releasing or pumping the brakes.
CAUTION:
In emergency situations, if the brakes are
not functioning properly, press and hold the Park
button on the overhead console or touchscreen to
bring Model Y to a stop. Do not use this method to
stop the vehicle unless absolutely necessary.
