Vehicle Hold is currently unavailable due to system constraints. When stopping, use the brake pedal to bring your
vehicle to a complete stop and keep your vehicle stationary.
What to do:
Continue to your destination. Your vehicle is OK to drive.
If this alert persists throughout subsequent drives, schedule service at your earliest convenience. Your vehicle is OK
to drive in the meantime.
For more information, see Vehicle Hold on page 72.
DI_a250
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.
The system cannot provide real-time adjustments to the suspension system to optimize both ride and handling, and
as a result your ride may be softer than usual.
What to do:
If this alert persists throughout subsequent drives, schedule service at your earliest convenience. Your vehicle is OK
to drive in the meantime.
This alert is accompanied by a red indicator light on the instrument panel. For more information, see Air Suspension
on page 129.

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.
