Pattern Select Switch Snow Mode Circuit [10/2017 - ]: Description

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

When SNOW is selected, the operation of the throttle motor is moderated to control engine output. This helps to reduce skidding of the drive wheels, and assists with takeoff acceleration, driving straightness and turning stability.
