When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
If the ignition is not switched off, or the
parking brake has not been applied, a warning chime will sound upon
opening the driver's door.
Manual mode If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, theshift is not executed. This prevents

If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
