Porsche Active Suspension
Management (PASM) with Air
Suspension and Level ControlPASM with air suspension is an active shock
absorber adjustment and ride height balancing
system. The adjustable damper system selects
the appropriate damping level for each wheel
according to the driving situation and driving
conditions. The level control system automatically
balances load changes and maintains a constant
ride height. Driving safety , agility and comfort are
optimised.
Three different chassis setups can be selected at
the push of a button:
– “PASM Comfort”
– “PASM Sport”
– “PASM Sport Plus”
Comfort mode ensures comfortable chassis
tuning.
The “PASM Sport” chassis setup offers very
sporty shock absorber tuning.
“PASM Sport Plus” mode offers particularly sporty
shock absorber tuning (e.g. for driving on the race
circuit). The vehicle is also lowered by
approx. 1 in. (25 mm) compared with the normal
level and the spring rate is increased.
In addition to manual mode selection, PASM also
adjusts shock absorber tuning for either sporty
or comfort driving, depending on the driving
situation.

the multi-function display in the instrument panel
for approx. 4 seconds.
Note
The mode cannot be changed if a door or the
tailgate is opened or when the engine is switched
off.
When the vehicle is stopped, the ride height may
be adjusted automatically
in order to balance the
vehicle load.
High LevelThe level control system al lows you to raise the
vehicle in maneuvering mode by approx. 0.8 in.
(20 mm) compared with the normal level in order
to drive over curbs and ramps.
High Level can only be selected manually and at
speeds of less than approx. 20 mph (30 km/h).
Note
High Level must not be us ed on public roads since
the prescribed installation height of the reflectors
can be exceeded in High Level.

Maintenance and Car Care
Exercise Extreme Caution when
Working on your vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially
cautious of devices such as hot water heaters
which ignite a flame intermittently.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around the engine at all
times while it is running. If you have to work on
the engine while it is running, always put the
parking brake on and put the PDK selector
lever in position P or N.
f In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get caught in the fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature,
even with the engine
switched off.
Carry out work in these areas only with the
engine off and exercise extreme caution.
f Your Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise
extreme caution when working on any part of
the engine while the ignition is on or the engine
is running.
f Always support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
Switch off level control of air suspension and
height adjustment.
Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 290.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive). f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty
coverage.
f Supplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
Keep these fluids out of children's reach and
dispose of them in accordance with the
appropriate regulations.
f Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.

Technical ModificationsfModifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are

tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversel y affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in the accessory market, it is not possible for
Porsche to inspect and approve every one.
f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.
