NOTE
*1: For vehicle not equipped with engine diagnosis connector model (Except RH steering vehicle not
equipped with rear fog light model)
The gear change is done at the shift point different from the above while any of the following control
functions is working. Bear this in mind when performing inspection.
• Slope Shift Control
When the AT controller makes up-slope judgment, Slope Shift Control (on up-slope) is executed by
changing the gear change point to the high-speed side so as to reduce frequent up-shift and down-
shift operations. When the AT controller makes down-shift judgment, Slope Shift Control (on down-
slope) is executed by changing the gear change point to the low-speed side so as to use engine-
brake function effectively while driving on a down-slope.
• Cruise Shift Control (if equipped with cruise control system)
Cruise Shift Control is executed by selecting appropriate gear according to requirement for
retaining a constant vehicle speed or acceleration so as to reduce frequent up-shift and down-shift
operations while cruising.
