2021 TESLA MODEL S brake

Key Fob
You can quickly familiarize yourself with the
key fob by thinking of it as a miniature version
of
Model S, with the Tesla badge representing
the front. The key has buttons that feel like
softer areas on the surface.
1.
Rear trunk - Double-click to open or close
the rear trunk. Hold down for one to two
seconds to open the charge port door.
2.
Lock/Unlock All - Single-click to lock
doors and trunks (all doors and trunks
must be closed). Double-click to unlock
doors and trunks.
3.
Front trunk - Double-click to unlatch the
front trunk.
Once inside, power up Model S by pressing
the brake pedal within two minutes of
pressing the unlock button on the key fob
(see
Starting and Powering Off on page 51).
If you wait longer than two minutes, you must
press the unlock button again, or place the key fob near the card reader located
in the lower half of the left wireless phone charger, facing downward, on the center console.
When your key fob is detected, the two
minute authentication period restarts.
When approaching or leaving Model S carrying the key fob, you do not need to point the key fob at Model S as you press a button,
but you must be within operating range.
Radio equipment on a similar frequency can affect the key. If this happens, move the key
at least one foot (30 cm) away from other
electronic devices (phones, laptops, etc.).
If the key fob does not work (for example, its
battery is dead), you can touch its flat side
against the card reader on the driver

Starting
When you open a door to enter Model S, the
instrument panel and touchscreen power on
and you can operate all controls. To drive
Model S, press the brake pedal and swipe up
or down on the touchscreen

Restarting the Touchscreen
If your touchscreen is unresponsive or demonstrates unusual behavior, you can restart it to potentially resolve the issue.
NOTE: To ensure the safety of vehicle
occupants as well as other road users,
restarting the touchscreen should be done
only when the vehicle is in Park.
1.
Shift into Park.
2.
Hold down both scroll buttons on the steering yoke until the touchscreen turns
black.
3.
After a few seconds, the Tesla logo
appears. Wait approximately 30 seconds
for the touchscreen to restart. If the
touchscreen is still unresponsive or demonstrating unusual behavior after a
few minutes, try power cycling the
vehicle. See
Power Cycling the Vehicle on page 52.
NOTE: Restarting the touchscreen also
activates the gear selector on the center console.
NOTE: Restarting the touchscreen using the
scroll buttons does not power Model S off
and on.
Power Cycling the Vehicle
If your vehicle demonstrates unusual behavior
or a nondescript alert is present, you can try
power cycling the vehicle to potentially
resolve the issue.
1.

The energy bar (a thin horizontal line at the bottom center of the instrument panel) displays
real-time energy usage. The bar is colored gray (or white if the display is in Dark mode) and moves to the right to represent energy being used during acceleration. The bar is green and
moves to the left to represent energy being gained through regenerative braking.
11.
When Autosteer is active and detects the driving lane, it is highlighted in blue (see Autosteer on page 93). Depending on the current driving scenario, you may see
neighboring lanes.
NOTE: In situations where Autosteer is unable to detect lane markings, the driving lane is
determined based on the vehicle you are following.
NOTE: If Navigate on Autopilot is active, the driving lane displays as a single blue line in
front of Model S (see Navigate on Autopilot on page 98).

Vehicle HoldWhen Model S is stopped
while in a driving gear, the
brakes are automatically
applied without you having to put your foot on the
brake pedal. Whether
stopped on a
flat surface or
a hill, Vehicle Hold keeps the
brake applied, provided your
foot remains
off the
accelerator and brake
pedals. The speedometer
displays this indicator to
inform you that Vehicle Hold
is actively braking
Model S.
To disengage Vehicle Hold, press the
accelerator pedal or press and release the
brake pedal.
NOTE: Shifting into Neutral also disengages
Vehicle Hold.
NOTE: After actively braking Model S for
approximately ten minutes, Model S shifts into
Park and Vehicle Hold cancels. Model S also
shifts into Park when you open the driver

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 123)
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. .
Brake Disc Wiping
To ensure brakes remain responsive in cold
and wet weather, Model S 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 S 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.
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 S 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 sound when you press the
brake pedal. To stop
Model S, apply steady
force to the brake pedal without releasing or
pumping. Drive cautiously and maintain a safe
distance from other road users

The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery. 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 black line displays on the energy bar
(see
Instrument Panel on page 60).
Parking Brake
To engage the parking brake, touch Controls > Safety > Parking Brake. Follow the onscreen
instructions.
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 S 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 S 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
