Automatic transmission
One-touch gearshifting
Even with an automatic transmission, you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action si-
multaneously limits the gear range of the
transmission (
page 150).Upshifting
Briefly press the gear selector lever to
the right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simulta-
neously extends the gear range of the
transmission.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.iTo avoid overrevving the engine when
the gear selector lever is moved to the
D- direction, the transmission will not
shift to a lower gear if the engine’s
max. speed would be exceeded.
