Lock-Up Function

WARNING: This page is about a different car, the 2023 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.

When the accelerator pedal is lightly depressed from the condition where the vehicle is driven on a flat road in "D range" at a constant speed of 50 km/h (31 MPH) or more, check that rpm does not change abruptly.
