Driving and Driving Safety
Warning!
The kickdown function is not active in manual
selection mode "M".
The kickdown function cannot be used to
downshift in manual selection mode "M".
f Therefore shift down manually when accelera-
ting (e.g. to overtake).
Shifting up
f Press upper part (+) of a rocker switch A or
f Push selector lever B forward in the M gate.
Shifting down
f Press lower part (–) of a rocker switch A or
f Push selector lever B back in the M gate.
Depending on driving speed and engine speed,
you can shift up or down at any time. Gear chan-
ges which would exceed the upper or lower
engine-speed limit are not executed by the control
unit.
You can change down two gears by quickly pres-
sing rocker switches A or selector lever B twice.
If PSM is active and the engine-speed limit is rea-
ched, an automatic upward shift is performed or,
just before idling speed is reached, a downward
shift is performed.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
If manual mode fails, the control electronics
switch to automatic mode.
In this event, the instrument panel will display
selector lever position D.
f To remedy the fault, please consult an
authorized Porsche dealer.
