The transmission will automatically
select the gear range suited for optimal

Warning! G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.

shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be ex-
ceeded.

If you press on the accelerator when the
engine has reached its rpm limit, the transmis-
sion will upshift beyond any gear range limit
selected.
