Construction
Selector indicator "M" light and gear position indicator light flash
• When the driver's shift operation is cancelled, the gear position indicator light and selector lever indicator "M"
light flash twice.
— When the TCM cancels a shift operation, all of the signals are pulsed ON/OFF and when finally input to the
instrument cluster, the on signal (ex. M1 signal when in 1GR) and the remaining three off signals (M2, M3,
M4) are reversed to off and on signals respectively.
• Based on a combination of inputted signals from the TCM, the instrument cluster determines the gear number
(1GR displayed as "1"), and flashes the gear position number in the gear position indicator light and the
selector indicator "M" light.

MANUAL MODE SHIFT CONTROL STRUCTURE
Features
• The manual mode shift control is activated by moving the selector lever from the D to M range position (selector
lever is shifted over toward driver side).
• Manual mode shift control with a manual shifting system allowing selection of gear positions by manual
operation of the selector lever forward (–) and back (+) has been adopted. Moreover, engine braking for all
gears in manual mode according to the gear ratio is available.
— Shifting between 1GR and 2GR when the vehicle is stopped is possible. Moreover, when shifting from the D
to M range while driving, the same gear position is maintained.
— Consecutive shifting in the M range has been adopted. When shifting down from M range 4GR or 3GR, one
gear can be skipped over by rapidly tapping the selector lever two times in the down-shift (–) direction.
• Selector lever position and gear position indicator lights, built into the instrument cluster, have been adopted.
The gear position indicator light displays the selected gear position.
— The selector indicator light includes a selector lever position indicator that displays selector lever positions
and, a gear position indicator light that displays gear positions.
