The warning indicator for the front area is located
on the dashboard.
The warning indicator for the rear area is located
in the rooflining at the rear of the loadspace.
The warning indicators for the various monitoring
areas (left and right) are subdivided respectively
into one green, 4 yellow and 2 red light segments.
C- Rear display – right monitoring area
D- Rear display – left monitoring areaIf ParkAssist is activated, the green light seg-
ments of the active warning indicators are lit up
continuously.
If the vehicle approaches an obstacle that has
been detected by the sensors, one or more of the
yellow or red light segments lights up, depending
on the distance to the obstacle.If the first yellow light segment lights up, the ob-
stacle is still 48 in. or 120 cm (to the front) or
48 in. to 59 in. or 120 to 150 cm (to the rear)
away.
A brief signal tone sounds when reversing.
Anintermittent tone sounds when the distance
becomes less than approx. 24 in. or 60 cm. The
fourth yellow light segment lights up.
Acontinuous tone sounds when the distance be-
comes less than approx. 10 in. or 25 cm (on vehi-
cles with trailer coupling: approx. 14 in. or
35 cm). The second red light segment lights
up.
If the obstacle is approached even closer, the sys-
tem may not be able to recognize the obstacle any
longer.
fSet the radio volume so that the signal tones
are not drowned out.
You can have the volume of the signal tones ad-
justed to your own requirements at your autho-
rized Porsche dealer.
Note on operation
If the obstacle is approached even closer after the
continuous tone sounds and the second red light

driving program)The functions of selector lever positions Dand M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
The currently selected gear is retained if you
change from D to M.
If you change 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“.
The kickdown function cannot be used to
downshift in manual selection mode “M“.
fTherefore shift down manually when accelerat-ing (e.g. to overtake).
Shifting up
fPress upper part (+) of a rocker switch Aor
fPush selector lever B forward in the M gate.
Shifting down
fPress lower part (–) of a rocker switch Aor
fPush selector lever B back in the M gate.

you can shift up or down at any time. Gear chang-
es 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 press-
ing rocker switches A or selector lever B twice.
If PSM is active and the engine-speed limit is
reached, an automatic upward shift is performed
or, just before idling speed is reached, a down-
ward 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.
