Front ultrasound sensorsSensors
Six ultrasound sensors in the front and rear bump-
ers measure the distance to the closest obstacle.
– Range of outer sensors
(front and rear):
approx. 24 in. (60 cm)
– Range of front middle sensors (arrow):
approx. 48 in. (120 cm)
Rear ultrasound sensors– Range of rear middle sensors (arrow)
(only in vehicles without spare wheel bracket):
approx. 59 in. (150 cm)
– Range of rear middle sensors
(only in vehicles with spare wheel bracket):
approx. 48 in. (120 cm)
Obstacles cannot be detected in the "blind" sensor
area (above and below the sensors).Maintenance note
fThe sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
fDo not damage sensors by abrasion or
scratching.
fMaintain sufficient distance when cleaning with
steam-jet units.
The sensors will be damaged if the pressure is
too high.
Note on operation
The rear ultrasound sensors may not function
correctly if tires that have not been recommended
by Porsche are fitted on the spare wheel bracket.
If the spare wheel bracket is open, this may impair
the function of the rear ultrasound sensors.
In vehicles that have air suspension with level
control and height adjustment, the system may
not recognise obstacles near the ground at terrain
level or special terrain level.

Air Suspension with Level Control
and Height AdjustmentOn vehicles with air suspension, the driver can set
five different level steps manually.
The preselected level is automatically adjusted to
suit the vehicle speed.
The height of the car is automatically kept
constant when the car is loaded.
Tip on driving
It is not permissible to drive on public roads with
the car in the terrain or special terrain setting.Note on operation
Frequent level changes can cause the compressor
to overheat. In this case, the compressor must
cool for several minutes before the level adjust-
ment is fully functional again.
Normal levelThe ground clearance at normal level is around
8.5 in or 217 mm.Terrain levelThis setting is intended for off-road driving, field
paths and forest paths, etc.
The vehicle is raised by around 1 in or 26 mm.
compared to normal level.
Terrain level can be selected only manually at
speeds below around 50 mph (80 km/h).
The car is automatically lowered to normal level at
speeds exeeding around 50 mph (80 km/h).
The car is automatically raised to terrain level
when Low Range is activated.
Special terrain levelThis setting is intended only for extremely chal-
lenging terrain requiring maximum ground clear-
ance. The vehicle is raised by 2.2 in or 56 mm
compared to normal level.
The warning light in the instrument panel comes
on when the special terrain level has been
reached.
Special terrain level can be selected only at
speeds below around 19 mph (30 km/h).
The car is automatically lowered to terrain level at
speeds exeeding around 19 mph (30 km/h).Low levelThis level is intended for high-speed driving. Above
speeds of around 78 mph (125 km/h), the car is
lowered by around 1 in or 27 mm compared to
normal level.
When the speed drops to below around 25 mph
(40 km/h), the car is automatically raised to nor-
mal level.Special low levelAt extremely high speeds, for example when oper-
ated on a race track, the car is lowered 0.4 in or
11 mm compared to the low level.
