Electronic Gearshift Selector - Lexus HS250h Hybrid 2010 Emergency Response Manual

Electronic Gearshift Selector

The HS250h electronic gearshift selector is a momentary select shift-by-
wire system that engages the transaxle in Reverse, Neutral, Drive, or
engine Brake modes.
These modes may only be engaged while the vehicle is on and operational
•
(READY-on), except for Neutral which may also be engaged while in the
ignition-on mode. After selecting the gear position R, N, D, or B the
transaxle remains in that position, identified on the instrument cluster, but
the shift selector returns to a default position. To select Neutral, it is
necessary to hold the shift selector in the N position for approximately 0.5
second.
Unlike a conventional vehicle, the electronic shift selector does not contain
•
a park position. Instead, a separate P position switch located below the
shift selector engages the park position.
When the vehicle is stopped, regardless of shift selector position, the
•
electro-mechanical parking pawl is engaged to lock the transaxle into park
by either depressing the P switch or pushing the power button to shut off
the vehicle.
Being electronic, the gearshift selector and the park lock systems depend on
•
the low voltage 12 Volt auxiliary battery for power. If the 12 Volt auxiliary
battery is discharged or disconnected, the vehicle cannot be started and
cannot be shifted out of park (P position).
