Common Symptoms
- Message to press the brake pedal in order to shift out of Park or change gear
- The car will not change from Park/Neutral until the brake is applied
- No warning once you press the brake and shift
- Normal, expected behavior
Probable Causes (Ranked by Likelihood)
- Normal interlock: Tesla (like most cars) requires the brake pedal to be pressed before shifting out of Park or into gear Very Likely
- A brake-pedal switch fault could, rarely, prevent the car from recognizing the brake is pressed Possible
Step-by-Step Diagnostic Procedure
This is an informational prompt, not a fault -- simply press and hold the brake pedal, then shift.
If the car will not shift even with the brake firmly pressed, the brake-pedal position switch may not be registering -- have Tesla service check it.
No repair is needed in normal operation.
