2020 TESLA MODEL S tire pressure

IndicatorDescription
An ABS (Anti-lock Braking System) fault is detected. See Braking and Stopping on
page 66. Contact Tesla immediately.The parking brake is manually applied. See Parking Brake on page 68.A parking brake fault is detected. Contact Tesla. See Parking Brake on page 68.Vehicle Hold is actively applying the brakes. See Vehicle Hold on page 73.Tire pressure warning. The pressure of a tire is out of range. If a fault with the Tire
Pressure Monitoring System (TPMS) is detected, the indicator

Caution: If the brakes are not functioning
properly, stop the vehicle as soon as safety permits and contact Tesla Service.
See Park on page 52 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 S is moving and your foot is
off the accelerator, regenerative braking slows
down Model S 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 S (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.
Warning: In snowy or icy conditions
Model S 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 67)
in snowy or icy conditions to help maintain vehicle stability.
The Energy app displays real-time feedback
on the amount of energy being gained by
regenerative braking. You can also display the
power meter on either side of the instrument
panel by choosing Energy using the scroll
button on the steering wheel (see Steering
Wheel on page 44).
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 yellow line displays on the power
meter.
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:

Tire Care and Maintenance
Maintaining Tire Pressures
Keep tires in

Checking and Adjusting Tire PressuresFollow these steps when tires are cold andModel S has been stationary for over three
hours:
1. Refer to the Tire and Loading Information
label located on the driver

Punctured Tires
A puncture eventually causes the tire to lose pressure, which is why it is important to check
tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when
penetrated, provided the object remains in the tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect a tire is damaged, immediately reduce yourspeed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to have Model S
transported to a Tesla Service Center, or to a nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 1/4” (6
mm)) using an optional tire repair kit available
from Tesla. This allows you to slowly drive
Model S to Tesla or to a nearby tire repair
facility.Warning: Do not drive with a punctured
tire that has not been repaired, even if the puncture has not caused the tire to
de

3.Follow the onscreen instructions.Caution: Selecting the incorrect wheel
size may result in false tire pressure
warnings. If a tire pressure warning
displays, exit the vehicle, close the
rear trunk and all doors, wait for the
touchscreen to go black, then re-
enter the vehicle and ensure that the
correct wheel size is selected before
touching Reset TPMS .
Note: On some older versions of Model S,
when changing to 21" wheels, the TPMS may
generate false tire pressure warnings. Bring
Model S to a Tesla Service Center for further
adjustment.
Warning: Do not reset the TPMS sensors
in an attempt to clear tire pressure
warnings.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays frequently, contact Tesla to determine if a tire
sensor needs to be replaced. If a non-Tesla Service Center repairs or replaces a tire, the
tire sensor may not work until Tesla performs
the setup procedure.
TPMS Malfunction
Model S has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the tire pressure
indicator light. When the system
detects a malfunction, the indicator
