2021 TESLA MODEL S brake

How It Works
The traction control system constantly
monitors the speed of the front and rear
wheels. If
Model S experiences a loss of
traction, the system minimizes wheel spin by
controlling brake pressure and motor power.
By default, the traction control system is on.
Under normal conditions, it should remain on
to ensure maximum safety.
This yellow indicator flashes
on the instrument panel whenever the traction
control system is actively
controlling brake pressure
and motor power to
minimize wheel spin. If the
indicator stays on, a fault is
detected with the traction
control system. Contact
Tesla Service.
WARNING: Traction control cannot prevent collisions caused by driving dangerously or turning too sharply at high speeds.
Allowing Wheel Slip
To allow the wheels to spin at a limited speed,
you can enable Slip Start. Slip Start can be enabled only when Model S is moving 30 mph (48 km/h) or slower. Slip Start automatically disables when the speed exceeds 50 mph (80 km/h).
Under normal conditions, Slip Start should
not be enabled. Enable it only in
circumstances where you deliberately want
the wheels to spin, such as:

WARNING: Due to limitations inherent in the onboard GPS (Global Positioning System), you may experience situations in which Traffic-Aware Cruise Control slows down the vehicle, especially near highway exits where a curve is detected and/or you are actively navigating to a destination and not following the route.
WARNING: Traffic-Aware Cruise Control cannot detect all objects and, especially in situations when you are driving over 50 mph (80 km/h), may not brake/decelerate when a vehicle or object is only partially in the driving lane or when a vehicle you are following moves out of your driving path and a stationary or slow-moving vehicle or object is in front of you. Always pay attention to the road ahead and stay prepared to take immediate corrective action. Depending on Traffic-Aware Cruise Control to avoid a collision can result in serious injury or death. In addition, Traffic-Aware Cruise Control may react to vehicles or objects that either do not exist or are not in the lane of travel, causing Model S to slow down unnecessarily or inappropriately.
WARNING: Traffic-Aware Cruise Control may be unable to provide adequate speed control because of limited braking capability and hills. It can also misjudge the distance from a vehicle ahead. Driving downhill can increase driving speed, causing Model S to exceed your set speed (and potentially the road

WARNING: Overtake Acceleration increases your driving speed whenever the appropriate turn signal is engaged, and accelerates Model S closer to the vehicle ahead. Although Traffic-Aware Cruise Control continues to maintain distance from the vehicle ahead, it is important to be aware that your selected following distance is reduced when Overtake Acceleration is active, particularly in cases where it may not be your intention to overtake the vehicle you are following.
Canceling and Resuming
To manually cancel Traffic-Aware Cruise
Control, press the right scroll wheel or press
the brake pedal.
NOTE: When Traffic-Aware Cruise Control
cancels, Model S does not coast. Instead,
regenerative braking slows down Model S in
the same way as when you move your foot off the accelerator when driving without Traffic-Aware Cruise Control (see Regenerative Braking on page 67).
WARNING: Traffic-Aware Cruise Control cancels, or may not be available, in the following situations:

WARNING: When Autopark is active, monitor the touchscreen and instrument panel to ensure that you are aware of the instructions that Autopark is providing.
To Pause Parking
To pause Autopark, press the brake pedal
once. Model S stops and remains stopped
until you touch Resume on the touchscreen.
To Cancel Parking
Autopark cancels the parking sequence when
you manually move the steering yoke, change
gears, or touch Cancel on the touchscreen.
Autopark also cancels parking when:

WARNING: The camera(s) and sensors associated with Forward Collision Warning are designed to monitor an approximate area of up to 525 feet (160 meters) in your driving path. The 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 S. When seeing and/or hearing a warning, it is the driver

WARNING: Automatic Emergency Braking is not a substitute for maintaining a safe traveling distance between you and the vehicle in front of you.
WARNING: The brake pedal moves downward abruptly during automatic braking events. Always ensure that the brake pedal can move freely. Do not place material under or on top of the driver

Auto-Raising Suspension
Auto-raising suspension saves you from
manually having to raise the suspension every
time you arrive at a frequently-used location
where you have previously raised the
suspension. Whenever you raise the suspension to
High or Very High, you can
touch Always Auto-Raise at This Location to
save the location. When you return to the
saved location,
Model S raises the suspension
and the instrument panel displays a message
indicating that the suspension is being raised.
NOTE: When returning to a saved location
and driving faster than the High and Very High suspension settings allow, the
suspension does not raise until
Model S slows
down.
NOTE: After leaving a saved location, the
suspension automatically lowers. However, it
may not lower until you are driving faster than the speed threshold at which the suspension lowers.
NOTE: If Model S reaches a saved location
and the existing suspension setting is already
higher than the level that has been saved for
that location, the ride height is not adjusted.
To remove an auto-raising location
If you do not want the suspension to auto- raise at a saved location, touch the X in the
auto-raising location status message that
displays at a saved location. Doing so
removes the auto-raise location and the suspension no longer raises automatically
when you arrive at the location.
Self-Leveling
Model S equipped with air suspension
automatically self-levels, even when power is
off. To prevent damage when jacking or lifting
the vehicle, you must activate Jack mode to
disable self-leveling (press the brake pedal
and touch
Controls > Service > Jack Mode).
For more details, see Jack Mode on page 201.

Cleaning the Exterior
To prevent damage to the paint, immediately
remove corrosive substances (bird droppings, tree resin, dead insects, tar spots, road salt,
industrial fallout, etc.). Do not wait until
Model S is due for a complete wash. If
necessary, use denatured alcohol to remove
tar spots and stubborn grease stains, then
immediately wash the area with water and a
mild, non-detergent soap to remove the alcohol.
Keep the exterior cameras free of dirt,
condensation, or obstructions. These
substances can cause unclear pictures or
Autopilot and safety features to stop working
(see
Cleaning a Camera on page 194).
Follow these steps when washing the exterior
of Model S:
1.
Rinse Thoroughly
Before washing, flush grime and grit from
the vehicle using a hose. Flush away
accumulations of mud in areas where
debris easily collects (such as wheel wells
and panel seams). If salt has been used on the highways (such as during winter months), thoroughly rinse all traces of road salt from the underside of the vehicle, wheel wells, and brakes.
2.
Hand Wash
Hand wash Model S using a clean soft
cloth and cold or lukewarm water
containing a mild, high-quality car shampoo.
CAUTION: Some cleaners and car shampoos contain chemicals that can cause damage or discoloration, especially to plastic trim pieces, lamps, or camera lenses. For example, some car cleaning formulas contain hydroxide or other highly alkaline or caustic ingredients that can damage exterior components. Damage or discoloration resulting from cleaning products is not covered by the warranty.
3.
Rinse with Clean Water
After washing, rinse with clean water to
prevent soap from drying on the surfaces.4.
Dry Thoroughly and Clean Exterior Glass
After washing and rinsing, dry thoroughly
with a chamois. If necessary, dry the
brakes by going on a short drive and applying the brakes multiple times.
Clean windows and mirrors using an
automotive glass cleaner. Do not scrape,
or use any abrasive cleaning
fluid on glass
or mirrored surfaces.
Cleaning a Camera
To ensure a clear picture, the camera lens
must be clean and free of obstructions.
Remove any build-up of dirt or debris by
spraying water onto the camera lens with a
spray bottle or pressure washer.
CAUTION: Do not attempt to remove dirt or debris by wiping an exposed lens with your hands or a cloth. This debris can damage the surface of the lens when rubbed against it during wiping.
CAUTION: Do not use chemical-based or abrasive cleaners. Doing so can damage the surface of the lens.
Cautions for Exterior Cleaning
CAUTION: Do not wash in direct sunlight.CAUTION: Do not use windshield treatment fluids. Doing so can interfere with wiper friction and cause a chattering sound.
CAUTION: Do not use hot water, detergents, or highly alkaline or caustic cleaning products, especially those containing hydroxide.
CAUTION: If using a pressure washer, maintain a distance of at least 12" (30 cm) between the nozzle and the surface of Model S. Avoid aiming the water jet directly at parking sensors (if equipped). Keep the nozzle moving and do not concentrate the water jet on any one area.
