When Tow mode is active, Model S
displays this indicator light on the
instrument panel, along with a
message telling you that Model S will
roll freely.
Note: In Tow mode, Model S does not shift
into a driving gear. To cancel Tow mode, shift
into Park or touch Tow mode again. Tow mode
also cancels if you use the touchscreen to
apply the parking brake (Controls > E-Brake &
Power
O > Parking Brake).
