10. The power meter displays real-time power usage. During acceleration, the bar fills to the right with a gray color
(or white if the display is dark) to represent power being used. During deceleration (when
Model S is moving and
you release your foot from the accelerator pedal), the bar
fills to the left with a green color to represent power
being fed back to the Battery by regenerative braking (see
Regenerative Braking on page 67).

63Seating and Safety Restraints

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 S braking system,
contact Tesla immediately.
Model S 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
instrument panel when you first start
Model S. 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 instrument panel displays this red
brake indicator at any time other than
briefly when you first start Model S, 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 instrument panel 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 67).
WARNING: When driving a Model S Plaid
equipped with the optional Carbon Ceramic Brake
Kit in temperatures below 14 degrees Fahrenheit
(-10 degrees Celsius), the instrument panel
displays an alert indicating that stability and
braking performance may be degraded in cold
weather. You may need to increase the amount of
pressure you apply to the brake pedal when
driving in cold weather. Be aware of this reduced
performance and drive cautiously in cold weather
conditions. The Apply Brakes When Regenerative
Braking is Limited feature is not available on a
Model S Plaid equipped with the optional Carbon
Ceramic Brake Kit.
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 115) 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.
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 S is rapidly slowing down. If Model S 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 60).
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.

Displaying Tire Pressures
Tire pressures display on the touchscreen by touching
Controls > Service. The pressure of each tire displays in
the visualization of your
Model S, in addition to what
time your tire pressures were last measured. You can choose whether you want to display tire pressures using Bar or PSI by touching
Controls > Display > Tire
Pressure. The touchscreen also displays your vehicle

If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for
optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 195) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model S, see Wheels and Tires on page 194.
If you replace a wheel, the TPMS (Tire Pressure Monitoring System) sensors need to be reset to ensure they provide accurate warnings when tires are under-
or
over-inflated (see Automatic Reset of TPMS Sensors on
page 176).
WARNING: For your safety, use only tires and
wheels that match the original specification. Tires
that do not match the original specification can
affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your
vehicle

the size indicated on the vehicle placard or tire inflation
pressure label, determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that displays a tire pressure telltale (Tire Pressure Warning) on the
instrument panel
when one or more of your tires is significantly under- or
over-inflated. Accordingly, when the Tire Pressure
indicator light displays on the
instrument panel to alert
you about tire pressure, stop and check your tires as soon as possible, and
inflate them to the proper pressure
(see
Maintaining Tire Pressures on page 173). Driving on
a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also
reduces range
efficiency and tire tread life, and may
affect the vehicle
