Braking Systems
WARNING: Properly functioning braking systems
are critical to ensure safety. If you experience a
problem with the brake pedal, brake caliper, or any
component of a Model 3 braking system, contact
Tesla immediately.
Model 3 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 3. 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 3, 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.
If the
touchscreen displays this yellow
brake indicator at any time, a brake
booster fault is detected. Apply steady
pressure and keep the brakes firm to
bring the vehicle to a stop when safe to
do so. Hydraulic Boost Compensation will
be active (see
Hydraulic Boost
Compensation on page 62).
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).
Automatic Emergency Braking is designed to
automatically brake in situations where a collision is
considered imminent (see Automatic Emergency
Braking on page 114).
WARNING:
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 your brakes remain responsive in cold and wet
weather, Model 3 is equipped with brake disc wiping.
When cold and wet weather is detected, this feature
repeatedly applies an imperceptible amount of brake
force to clear away water from the surface of the brake
discs.
Hydraulic Fade Compensation
Your vehicle is also equipped with hydraulic fade
compensation. This feature assists in monitoring brake
system pressure and ABS activity for instances of lower
brake performance. If lower brake performance is
detected (for example, as a result of brake fade, or cold
or wet conditions), you may feel the brake pedal pull
away from your foot, detect some noise, and notice a
strong increase in vehicle braking. Continue to press the
brake pedal without releasing or "pumping" them—
brake as you normally would.
CAUTION:
If brakes are not functioning properly,
stop the vehicle as soon as safety permits and
contact Tesla Service. See Park on page 53 for
information on using the Park button to stop the
vehicle in case of emergency.
