Braking SystemsWARNING: 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
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. 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 61).
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).
NOTE: Automatic Emergency Braking (see Automatic
Emergency Braking on page 118) 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.
Brake Disc Wiping
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.
Hydraulic Fade Compensation
Model Y is also equipped with hydraulic fade
compensation. This feature 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, feel the brake pedal pull away from your foot, and notice a strong increase in braking. Brake as you
normally would and continue to press the brake pedal
without releasing or "pumping".
CAUTION: If brakes are not functioning properly,
stop the vehicle when safety permits and contact
Tesla Service. See Park on page 52 for information
on using the Park button to stop the vehicle in
case of emergency.
WARNING: Always maintain a safe driving distance
from the vehicle in front of you and exercise
caution when driving conditions are hazardous.
Brake disc wiping and hydraulic fade
compensation is not a substitute for adequately
applying the brakes.
