Assist for low brake performance activated
To stop, keep brake pedal firmly pressed
What this alert means:
Hydraulic Fade Compensation is active. This brake assist function activates temporarily to make sure you have full braking
capability in conditions where reduced braking performance is detected by your vehicle.
When this assist function activates, you may feel the brake pedal pull away from your foot and notice a strong increase in brake
pressure. You may also hear a pumping sound coming from the brake hydraulic unit at the front of the vehicle. This will usually
last for a few seconds, depending on road surface and vehicle speed. This is completely normal and does not indicate any
issue with your vehicle.
What to do:
Continue to press the brake pedal as you normally would, and do not "pump" (repeatedly press and release) the pedal as this
will interrupt the function.
This alert will clear when your vehicle comes to a stop or you are no longer pressing the brake pedal. It may still be displayed
for up to 5 seconds afterward.
Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake temperatures
after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your brake pads or rotors have
worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla service at
your convenience for a brake inspection.
For more information, see Hydraulic Fade Compensation on page 81.

Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
What this alert means:
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This may be due to power supply disturbances caused by the external charging equipment or by the electrical power grid. In
some cases, this condition may be the result of using nearby electric devices that draw a lot of power.
