DESCRIPTION
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 "+" (up shift) or "-" (down shift) shift paddle switch, the gear can be changed.
When the vehicle is being driven with the shift lever in D (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 "+" (up shift), or "-" (down shift) shift paddle switch is not operated.
