Assist for low brake performance activated
To stop, keep brake pedal firmly pressed
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.
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.
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.
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.

Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
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 condition could occur due to power supply disturbances caused by the external charging equipment or by the
electrical power grid. In some cases, this condition can even result from turning on nearby electric devices that draw
a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
This alert may be accompanied by another alert that specifies the condition affecting AC charging. If so, it is
recommended you start by investigating that alert.
Further troubleshooting tips based on equipment type:
• If using a Mobile Connector, try charging your vehicle with a different wall outlet.
