Porsche 911 CARRERA - 2003 Manual page 129

Tiptronic S
The Porsche Tiptronic is a five-speed trans-
mission with an "Automatic" and "Manual" selec-
tion mode.
In automatic selection mode (selector lever
position D), gear-changing is automatic.
You can change temporarily from automatic to
manual mode using the toggle switches on the
steering wheel.
In manual selection mode (selector lever
position M), you change gear using the toggle
switches on the steering wheel.
You can change between selector lever position
D and M as you wish while driving.
Note
Take care not to operate the toggle switches on
the steering wheel inadvertently in either auto-
matic or manual mode, thereby triggering un-
desired gear changes.
Locking button
To prevent unintended gear shifts, the locking
button in the selector lever (arrow) must be
pressed to change to position
R or P.
Keylock position
This position allows the ignition key to be
removed only after the gearshift selector lever
button is depressed and moved to position "P".
This ensures that the driver engages the parking
lock before leaving the vehicle and turns the
ignition key to position "0", then the ignition key
can be removed from the ignition switch.
Shiftlock (selector lever lock)
The
shiftlock system is another feature to pre-
vent inadvertent movement of the vehicle.
Ignition switch position 0
The
selector lever (locking button) is locked.
Ignition switch position 1
With the vehicle stationary, the selector lever
cannot be moved from
the P or N
positions,
unless the brake pedal is depressed.
Starting the engine
The engine can be started only in selector lever
position
P or N.
Drivingoff
I>
Select the desired drive position (D, M or R)
for driving off only when the engine is idling
and while depressing the brake pedal.

Since the car creeps when in gear, do not
release the brake until you want to drive off.
I>
After
selecting a gear, do not accelerate until
you can feel that the gear has been selected.
