Porsche Boxster Owner's Manual page 181

Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine speed limit are not executed by the
controller.
There is no automatic upshift at the upper engine
speed limit in selector lever position M. Upshift
suppression can be cancelled by kickdown opera-
tion. If, for example, the engine speed limit is
reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up as a result of kickdown operation.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
In order to shift up automatically at the upper
engine speed limit:
f Depress the accelerator pedal beyond the full-
throttle point (kickdown).

ately stop the vehicle in a suitable place. Have
the vehicle towed to an authorized Porsche
dealer.
Please see the chapter "TOWING" on
Page 269.
Stopping
f For a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
f Before leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Parking
f Go easy on the accelerator!
f When parking or manoeuvring in a small
space, control the speed by careful use of the
footbrake.
Driving in winter
In wintry road conditions it is advisable to take
steep inclines in manual mode. This prevents gear
changes occurring that could cause wheelspin.
