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.
The ABS indicator briefly
flashes yellow 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
aected 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. Apply
steady pressure and keep
the brakes
firm to bring the
vehicle to a stop when safe
to do so.
The touchscreen displays
this yellow 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
Compensation will be active
(see
Hydraulic Boost
Compensation on page
71).
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.
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 Automatic Emergency
Braking on page 127) 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 drive stalk to bring the
vehicle to a stop. Do not use this
method to stop the vehicle unless
absolutely necessary.
