when the transmission is ready to shift. The arrows on the Driver
Display Module ( see Fig.) indicate

- Release the throttle for the shift to neutral. The upcoming gear flashes on the display when neutral is engaged. The arrows disappear, the current gear position stops flashing, and engine rpm decreases and becomes steady.
- Apply the throttle.
Note: If the shift is missed, control engine speed in the direction indicated by the arrows on the display to synchronize engine rpm with the transmission's speed.
Note: It is the driver who decides when to upshift or downshift. When in the "D" (drive) mode, an upcoming shift can be cancelled by putting the gear select lever in the "H" mode or by using the gear select handle buttons. When in the "H" (hold) mode, it is possible to skip shift gears if the road and load conditions permit.
Note: In the "H" mode, depress the upshift button on the gear select handle. Depress twice to skip shift.
