2023 TESLA MODEL 3 ABS

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 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 amber 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
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 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.
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
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).
CAUTION: Automatic Emergency Braking (see
Automatic Emergency Braking on page 112) 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.
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 3 is rapidly slowing down. If Model 3 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 55).
NOTE: Dynamic brake lights will not flash while Track
Mode is enabled (see
Track Mode on page 69).
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.
WARNING: When towing a trailer (if applicable),
always increase your following distance. Sudden
braking may result in skidding, jack-knifing, and
loss of control.
Brake Disc Wiping
To ensure 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 remove water from the surface of the brake discs.

Hydraulic Fade Compensation
Model 3 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, 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 the
brakes.
CAUTION: If brakes are not functioning properly,
stop the vehicle when safety permits and contact
Tesla Service. See Park on page 51 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.
Hydraulic Boost Compensation
Model 3 is equipped with a brake booster that activates
the brakes when the brake pedal is pressed. Hydraulic boost compensation provides mechanical assistance if the brake booster fails. If a brake booster failure is detected, the brake pedal feels
stiffer to press and you
may hear a sound when you press the brake pedal. To
stop
Model 3, apply steady force to the brake pedal
without releasing or pumping. Drive cautiously and
maintain a safe distance from other road users

Replacing the Low Voltage Lead-Acid Battery
This procedure is intended for vehicles in North America
only.
CAUTION: To avoid damage that is not covered by
the warranty, replace your low voltage lead-acid
battery with the same type of battery. The low
voltage lead-acid battery for North American
vehicles is AtlasBX / Hankook 85B24LS 12V 45Ah.
You can purchase a new lead-acid low voltage
battery that is compatible with your vehicle from
your local service center
NOTE: Vehicles manufactured between approximately
July 2017 and October 2020 do not have a heat pump and should use
Vehicles Manufactured Before
Approximately October 2020 on page . Vehicles
manufactured afterward have a heat pump and should
use
Vehicles Manufactured After Approximately October
2020 on page .
Perform the following procedure to replace the lead- acid low voltage battery. Wear appropriate personal protection equipment (such as safety glasses, leather gloves when handling the lead-acid battery etc.).
Vehicles Manufactured Before
Approximately October 2020
Removal:
1.
Prepare the vehicle to remove the low voltage lead-
acid battery:
a.
Ensure the vehicle is in Park.
b.
Lower all windows.
c.
Open the front trunk.
d.
Leave a door propped open so you can get back
into the vehicle if needed.
e.
Disconnect the charge cable from the charge port.
2.
Move the driver and front passenger seat fully forward.
3.
Under the rear seat, press the left and right tabs to the side and lift the seat cushion up. The seat separates from the base but is still restrained by one wire harness on each side.
4.
Disconnect the wire harnesses and remove the seat cushion. Set the cushion aside.
5.
In the front trunk, remove the vehicle
