Danger!
The seat may move unexpectedly if you at-
tempt to adjust while driving. This could
cause sudden loss of control or personal in-
jury.
fDo not adjust seats while the vehicle is in mo-
tion.The backrest locks must be engaged at all
times while the vehicle is in motion.
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body. Improperly posi-
tioned safety belts can cause serious person-
al injury or death in an accident.
fDo not operate the car with the driver or pas-senger backrests excessively reclined.
Seat positionA correct sitting position is important for safe and
fatigue-free driving. We recommend the following
procedure for adjusting the driver’s seat to suit
individual requirements:
1. Adjust the seat height to give yourself enough
headroom and a good overview of the vehicle.
2. Adjust the seat until, with the accelerator pedal
fully depressed, your leg is straight but your
entire foot still rests on the accelerator pedal.
3. Grip the top half of the steering wheel. Set the
backrest angle and steering wheel position so
that your arms are almost outstretched.
However, your shoulders must still rest on the
backrest.
4. If necessary, correct the seat fore-and-aft
adjustment.
5. Adjust the height of the headrest so that the
upper edge is at eye level or higher.

B Rear seat height adjustment.
C Fore and aft adjustment.
D Backrest angle adjustment.
E Lumbar support adjustment.
To permit a relaxed sitting posture, the back-
rest curvature is infinitely adjustable in vertical
and horizontal directions for individual pelvis
and spinal column support.
fPress the switch in the direction indicated by
the arrows until the desired setting is reached.

Automatic locking retractorThe safety belts for the passenger and rear seats
are equipped with an automatic locking retractor
for securing the child restraint system. When acti-
vated, this retractor allows you to securely fasten
the child restraint system in place so that inadvert-
ent movements will not occur.
Activating the automatic locking retractor
1. Pull the safety belt retractor completely out. At
this point the locking mechanism is activated.
2. Insert the safety belt tongue into the buckle
and make certain that it is properly latched.
3. Allow the safety belt to retract until it is tight on
the child restraint system. You may further
tighten the belt by pulling on it to allow more of
it to retract.
Releasing the safety belt
1. Unbuckle the safety belt latch.
2. Then make certain that the belt has fully re-
tracted. At this point the automatic locking fea-
ture will be disengaged.

Front ultrasound sensorsSensors
Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest ob-
stacle.
– 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.

Water crossingfPlease observe the chapter “GROUND CLEA-
RANCE” on Page 366.
Danger!
Danger of drowning if water enters the vehi-
cle. Risk of damage to the engine and acces-
sories if water penetrates.
fBefore driving through water, check the water
depthA, water speed and the condition of the
surface beneath it.
The water must not be deeper than 20 in./
50 cm (22 in./55.5 cm for vehicles with level
control and height adjustment).
fCheck the door sills and rubber seals before
starting to drive.
fDo not drive through deep or rapidly flowing
water.
Deep or rapidly flowing water, e.g. mountain
streams, can cause the car to deviate from the
desired path.
fAvoid a "bow wave" by driving at an appropriate
speed.
fNever open the doors when driving through wa-
ter.Soiling can impair the braking action.
fCheck and clean the brakes if they have been
soiled.
Danger of steering assistance failing during
a long journey in the water if the drive belt
slips.
fIf the steering assistance fails, more effort will
be required to steer.
Danger of damaging electrical systems
fAvoid driving through salt water.
Notes on operation
fActivate Low Range.
fSwitch the air conditioner off.
fSwitch the headlights off.

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. (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. (26 mm) com-
pared 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. (56 mm)
compared to normal level.
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 9 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. (27 mm) compared to nor-
mal 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.
(11 mm) compared to the low level.
