Shifting

■

Driving mode-speciIc shift characteristics

The driving mode selector switch allows the driver to choose the automatically shifted

AUTO mode or a manually shifted SPORT, NORMAL or WET mode and their

corresponding default shift speed level. The driver may perform gear changes using the

paddle shift switches while driving in a manually shifted driving mode. While the shift speed

is adjustable using the shift speed selector, each driving mode has its own default shift

speed setting. Shift speeds are determined by how quickly the following operations are

carried out: Clutch disengagement, gear select, gear shift and clutch engagement.

Selecting a faster shift speed will shorten the time it takes from the moment the paddle shift

switch is pulled until the shift is totally completed. Faster shift speeds allow for enhanced

response and near-seamless power delivery, but will also result in a greater amount of shift

shock due to the speed at which the aforementioned operations are carried out. Selecting

a slower shift speed will allow the clutch and gear shift/select mechanisms to operate at a

more gentle pace, leading to a smoother application of torque and less shift shock.

Shift speed selector

When in a manually shifted driving

mode (SPORT, NORMAL or WET),

the shift speed can be adjusted from

level 1 to 7 using the shift speed

selector.

Shift speed is also determined by the

accelerator pedal angle. The more the

accelerator pedal is depressed, the

shorter the shift times will be.
