getting too warm, so charging has been slowed to protect the wiring and Wall Connector.
This is not typically an issue with your vehicle or your Wall Connector, but rather an issue with the building wiring.
This may be caused by a loose building wiring connection to the Wall Connector and can be fixed quickly by an
electrician.
What to do:
Contact an electrician to inspect the building wiring connection to the Wall Connector. They should make sure that
all wires are properly connected and torqued according to the installation guide for the Wall Connector.
Wall Connector installation guides can be found here.

In some cases, your vehicle may be unable to continue driving. If this occurs, another vehicle alert should also be
present to provide more information and recommended actions.
This alert may be caused by a temporary condition that will be resolved automatically. If this alert clears during your
current drive, or is no longer present when you start your next drive, it was likely caused by a temporary condition.
No action is required.

Adaptive ride control disabled
Drive with caution
What this alert means:
The speed of your vehicle is limited to 90 mph (144 km/h) due to an issue with the Adaptive Suspension Damping
system.

ESP_a118
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 67.
