For each gear position while in the manual mode, the speed limit is set as follows: When the selector lever is operated within the range of the speed limit, the gear is shifted.

Shift up
The gear does not shift up while the vehicle speed is lower than the speed limit.
Shift down
The gear does not shift down while the vehicle speed exceeds the speed limit.
If the vehicle speed exceeds the speed limit and the gear does not shift down, the gear position indication flashes 2 times to notify the driver that the gear cannot be shifted.
Kickdown
When the accelerator pedal is depressed fully while driving, the gear shifts down.
However, the gears do not kickdown while the DSC is turned off.
NOTE
The gear also shifts down using kickdown while in the second gear fixed mode.
Auto-shift down
The gear shifts down automatically depending on the vehicle speed during deceleration.
NOTE
If the vehicle comes to a stop while in the second gear fixed mode, the gear remains in second.
