brakes TESLA MODEL 3 2020 Owner's Manuals

Caution: If the brakes are not functioning
properly, stop the vehicle as soon as safety permits and contact Tesla Service.
See Park on page 56 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 be cautious in hazardous driving
conditions. Do not rely on brake disc
wiping or hydraulic fade compensation to act as a substitute for adequate braking.
Regenerative Braking
Whenever Model 3 is moving and your foot is
off the accelerator, regenerative braking slows
down Model 3 and feeds any surplus energy back to the Battery.
By anticipating your stops and reducing or
removing pressure from the accelerator pedal
to slow down, you can take advantage of regenerative braking to increase driving range.
Of course, this is no substitute for regular braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model 3 (such as when your foot is
completely off the accelerator pedal at
highway speeds), the brake lights turn on to
alert others that you are slowing down.
Note: Installing winter tires with aggressive
compound and tread design may result in
temporarily-reduced regenerative braking
power. However, your vehicle is designed to continuously recalibrate itself, and after changing tires it will increasingly restore
regenerative braking power after some
moderate-torque straight-line accelerations.
For most drivers this occurs after a short
period of normal driving, but drivers who
normally accelerate lightly may need to use
slightly harder accelerations while the
recalibration is in progress.
Warning: In snowy or icy conditions
Model 3 may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 66)
in snowy or icy conditions to help maintain vehicle stability.The amount of energy fed back to the Battery
using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed line displays on the energy bar (see
Driving Status on page 63).
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:

Note: The parking brake operates on the rear
wheels only, and is independent of the pedal-
operated brake system.
Warning: In snowy or icy conditions the
rear wheels may not have sufficient
traction to prevent Model 3 from sliding
down a slope, particularly if not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always responsible for parking safely.Warning: Your Model 3 may display an
alert if the road is too steep to safely park
on, or if the parking brakes are not
properly engaged. These alerts are for
guidance purposes only and are not a
substitute for the driver’s judgment of safe parking conditions, including specific
road or weather conditions. Do not
depend on these alerts to determine
whether or not it is safe to park at any location. You are always responsible for
parking safely.When you use the touchscreen to
manually apply the parking brake,
the red parking brake indicator lights
up on the touchscreen.If the parking brake experiences an
electrical issue, the amber parking brake indicator lights up and a fault
message displays at the top of the
touchscreen.Caution: In the unlikely event that Model 3
loses electrical power, you cannot access
the touchscreen and are therefore unable to release the parking brake without first
jump starting Model 3 (see Instructions
for Transporters on page 199).Brake Wear
Model 3 brake pads are equipped with wear indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their service life and require replacement. To
replace the brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by removing the tire and wheel. For detailed
specifications and service limits for rotors and
brake pads, see Subsystems on page 188.
Additionally, Tesla recommends cleaning and
lubricating the brake calipers every year or
12,500 miles (20,000 km) if in an area where
roads are salted during winter months.Warning: Neglecting to replace worn
brake pads damages the braking system
and can result in a braking hazard.
Braking and Stopping

Vehicle Hold
When Model 3 is stopped, Vehicle Hold can
continue to apply the brakes even after you
remove your foot from the brake pedal. When
driving on a hill or on a

area being monitored by Forward
Collision Warning can be adversely
affected by road and weather conditions.
Use appropriate caution when driving.Warning: Forward Collision Warning is
designed only to provide visual and
audible alerts. It does not attempt to
apply the brakes or decelerate Model 3.
When seeing and/or hearing a warning, it
is the driver
