Driving Mode-Specific Shift Characteristics; Shift Speed Selector - Lexus LFA Owner's Manual

Driving mode-specific 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.

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.
