Manual Mode Control
By operating the "+" or "-" switch on the select lever or steering wheel in D range with the sports mode switch ON (in sports mode), the system switches to manual mode. In this mode, operating the "+" switch causes upshifting while operating the "-" switch causes downshifting; manual shifting is enabled and the selected gear position is held while driving.
However, at certain vehicle speeds or ATF temperatures, the following inhibiting control is performed.
- Upshift inhibiting and auto downshift control
The gear upshifts each time the "+" switch is operated, however, when the vehicle speed is too low for the selected gear speed, the TCM inhibits further upshifting. If the vehicle speed becomes too slow for the current gear speed, a downshift will be made automatically to prevent engine stall. When the vehicle comes to a stop, the transmission will always be controlled to shift to 1st speed unless the vehicle was in manual 2nd hold control.
- Downshift inhibiting control
The gear downshifts each time the "-" switch is operated, however, when the vehicle speed is too low for the selected gear speed, the TCM inhibits further shifting. A manual shifting inhibiting buzzer will sound to warn the driver.
- Control when oil temperature is low
When the ATF temperature is low as in cases such as immediately after start in winter, upshifting to 5th is inhibited to quicken warm up.
- Engine over speed prevention control
If the engine speed exceeds the preset value during accelerating, the fuel supply is cut to prevent over-revving of the engine.
