Shift Paddle Switch Circuit [10/2017 - ]: Description

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2024 Lexus IS 350, 2023 Lexus IS 350, 2022 Lexus IS 350, 2021 Lexus IS 350, and 2020 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

When the shift lever is in D, operating the "-" side shift paddle switch will cause the transmission to enter fixed range mode which restricts the highest gear. By operating the shift paddle switches "+" (up-shift) or "-" (down-shift), the shift range can be changed.

When the vehicle is being driven in D position (fixed range mode), if the vehicle is stopped or the accelerator pedal is kept steady for a certain period of time with the transmission in the same gear, the vehicle will change back automatically to normal D position operation.

When the shift lever is in M, it is possible to make use of the highest engine speeds by holding the vehicle in a gear. Gear hold control means that gear shifts will not be performed as long as the paddle switches are not operated in either the "+" (up-shift), or "-" (down-shift) direction.
