While this alert is present, the deceleration rate of the
vehicle due to regenerative braking will be reduced and
more brake pedal application will be required to slow
the vehicle (similar to what is needed in a gas-powered,
non-electric, vehicle).
This alert is expected under the following conditions:
•
Battery is near full charge:
◦
Regenerative braking is reduced when the battery
is at 95% charge or higher.
•
Battery is cold:
◦
The battery may not be warm enough for full
regenerative braking performance (possibly at the
beginning of a drive).
◦
In extremely cold climates, this alert may remain
present indefinitely and regenerative braking may
remain reduced, as driving the vehicle may not
warm the battery enough to fully restore
performance.
Typically, driving will clear this alert because it will
reduce the battery charge level below 95% and
suciently warm the battery.
This is a completely normal part of vehicle operation and
should not cause alarm. The notice on the screen is for
your information only.
For more information on regenerative braking, see the
Regenerative Braking section in the Owner’s Manual.

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.
For more information, see Hydraulic Fade Compensation
on page 61.

AC charging interrupted
Check power source and charging
equipment
Power has been lost during charging. This could result
from the charging equipment losing power from the
source (for example, a wall outlet) or from an issue with
the charging equipment.
