142 Driving and operating
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, the
shift is not executed. This prevents
the engine from running at too low or
too high an engine speed.
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.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
