Loading level
Caution!
Risk of damage to running-gear parts, units
and the vehicle underbody.
If the car is driven off a curb when at loading level,
for example, insufficent ground clearance can
cause it to bottom out.
fAlways switch to normal level before moving off.
This setting makes it easier for you to load the lug-
gage compartment.
The vehicle is lowered by around 2.4 in. (60 mm)
compared to normal level.
The car is automatically raised to normal level at
speeds exceeding around 3 mph (5 km/h).
Setting level manuallyPreconditions
–Ignition on.
– Doors are closed.
Setting
fMove rocker switch in the appropriate direc-
tion.
This sets the next possible height.
Indication of selected level
The corresponding light-emitting diode beside the
rocker switch flashes during the control process.
The light-emitting diode is continuously lit after the
control process.
The level change is also indicated on the multi-pur-
pose display of the instrument panel.
Exceptions
Automatic changes from normal level to low level
and back are not indicated on the multi-purpose
display of the instrument panel.
Note on operation
The level selected last is stored in memory after
the ignition is switched off.Raising the vehicle

Warning messageVarious messages are indicated on the multi-pur-
pose display of the instrument panel if there is a
system fault or if the compressor switches off due
to overload.fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 124.
fAdapt your driving style to the changed condi-
tions.
fConsult an authorized Porsche dealer in order
to remedy a system fault.
fIf the overload-protection function causes the
compressor to switch off, wait for a time until
it has cooled down. The system will function
again as soon as it has cooled sufficiently.
The warning message appears when the control
system is switched off and when the collapsible
spare wheel is being filled. This does not indicate
a fault.
The warning message will go out once these pro-
cedures have been completed.
Raising vehicle with the jackWhenever it is necessary to jack up the vehicle:
fManually set normal level and then switch off
level control.
Switching off level control
1. Switch ignition on.
2. Push rocker switch forward for 5 to
10 seconds.
A message is shown on the multi-purpose
display of the instrument panel.
The vehicle can now be raised.
Switching level control back on
1. Switch ignition on.
2. Push rocker switch forward for 5 to
10 seconds or
3. Drive forward with the vehicle.
Level control switches on automatically.Transporting the vehicles on car trains,
ferries and car transportersfTie the vehicle down only at its wheels.

Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire's ability
to stop on wet pavement as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning!
The traction grade assigned to this is based
on braking (straight-ahead) traction tests
and does not include cornering (turned) trac-
tion, acceleration, hydroplaning or peak
traction characteristics.Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire's resistance to the gener-
ation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperatures can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately
or in combination, can cause heat buildup
and possible tire failure.

Practical Tips, Minor Repairs
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may build up between the
tires and the road. This phenomenon is
known as “hydroplane“ and may cause par-
tial or complete loss of traction, vehicle con-
trol or stopping ability.
fReduce speed on wet surfaces to prevent this.Tire lifeTire life depends on various factors, i.e., road sur-
faces, traffic and weather conditions, driving hab-
its, type of tires and tire care.
fInspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.
Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more adja-
cent grooves, it is time to replace the tires. We
recommend, however, that you do not let the tires
wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.
Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle and could cause serious
personal injuries or death.
fDo not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause
severe personal injury.
fSpecialized high performance tires on high
performance sport utility vehicles exhibit more
wear than those on a family sedan, or even a
high performance sedan.
Therefore, it is important to check your tire
pressure and condition at least every two weeks.
fIf you notice that tires are wearing unevenly,
consult your Porsche dealer.
Uneven wear may not always be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is not checked and adjusted reg-
ularly, abnormal tire wear can also occur.
