Shifting Gear
151
M - Manual Selection Mode The currently selected gear is retained if you
change from D to M.
If you shift from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Warning!
The kickdown function is not active in manual
selection mode “M”.
fTherefore shift down manually when accelera-ting (e.g. to overtake). Two toggle switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward gears.
Shifting up
fPress upper part (+) of a toggle switch.
Shifting down
fPress lower part (–) of a toggle switch.
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or lo-
wer engine-speed limit are not executed by the
controller.
You can shift down two gears at once by quickly
pressing the toggle switches twice.
If the engine-speed limit is reached, an auto matic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
fSelect 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 cluster will display selector lever posi-
tion D.
fTo remedy the fault, please consult an authori-
zed Porsche dealer.

Warning!
When opening or closing the convertible top,
serious personal injury may occur if a per-
son’s body parts are near or in the way of the
convertible top mechanism’s moving parts.
fMake absolutely sure that nobody can be inju-
red by the convertible-top mechanism or the convertible-top compartment lid. Do not operate convertible top:
– At temperatures below 32°F/0°C.
– When one side of the car is on a curb, a hoist
or a jack.
– When items of luggage or other objects hinder
the convertible top movement or are in abrasi-
ve contact with the convertible top or rear win-
dow.
Items of luggage or objects on the luggage
tray above the engine compartment lid must
be put in the storage box or be secured under
the net to prevent their sliding out.
– Drive only with the convertible top fully open or
closed.
fAvoid frequent operation of the convertible top
with the engine off; the vehicle battery would
be unintentionally discharged rapidly.
fThe convertible top must be operated only
when the car is stationary. Make sure there is
sufficient clearance above the convertible top
(e.g. in the garage).
fTo prevent damp stains and abrasions, only
open the convertible top in a dry, clean state.

as the fabric, rubber material and color can be
harmed by long exposure to sunlight.
