Controls, Safety, Instruments
Dear Porsche OwnerA lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections. These
engineering and safety features will be enhanced
by you...the safe driver...– who knows his car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages. If in doubt, have these checks performed
by your authorized Porsche dealer.
Before driving off...Check the following items firstfTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary. Make
it a habit to have engine oil checked with every
fuel filling.
fCheck all fluid levels such as windshield wash-
er and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unobstruct-
ed.
fCheck air intake slots and area between en-
gine compartment lid and windshield are free
of snow and ice, so the heater and the wind-
shield wipers work properly.fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipmentIt is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are: window
scraper, snow brush, container or bag of sand or
salt, emergency light, small shovel, first-aid kit,
etc.

Tire PressurefPlease observe the chapter “TIRES/WHEELS”
on Page 285.
The tire pressure monitoring continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for tire
pressure monitoring are done on the multi-
purpose display in the TIRE PRESSURE menu.
However the tire pressure must be set manually
on the wheel.
The tire pressures to be monitored for tire type
are permanently set in the tire pressure
monitoring and cannot be changed.
The driver is solely responsible for filling the tires
correctly and for selecting in the multi-purpose dis-
play.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure in-
creases increases risk of a tire failure and re-
sulting loss of control. Furthermore, low tire
pressure increases rate of wear of the affect-
ed tires.
Despite the advantages offered by the tire
pressure monitoring, it is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the tire
pressure monitoring low tire pressure mes-
sage.
fWhen a flat tire has been displayed, immediate-
ly stop in a suitable place and check the tires
for damage. If necessary remedy the damages
with tire sealant.
fDo not by any means continue to drive with
leaking tires.
fDefective tires must be immediately replaced
by a specialist repair shop.
Tire repairs are not permissible under any
circumstances.
fSealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
repair shop. The maximum permitted speed is
50 mph (80 km/h).fDo not drive with tires whose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by a specialist re-
pair shop.
fIf the tire pressure monitoring is defective
(e.g., defective wheel transmitter), contact a
specialist workshop immediately and have the
damages repaired.
The tire pressure will not be monitored by a de-
fective tire pressure monitoring.
fTires lose air over time without a tire defect be-
ing present. A tire pressure warning will then
appear in the multi-purpose display. Correct
the tire pressure at the next opportunity.
fThe tire pressure monitoring gives a warning
about tire damages due to insufficient tire
pressure as well as about a gradual loss of
pressure due to foreign objects.
The tire pressure monitoring cannot warn you
about tire damages occurring suddenly (e.g.,
flat tire due to sudden external effects).
fBefore fitting tires approved by Porsche which
are not stored in the on-board computer, the
missing information should be supplemented
in the on-board computer.

Tire pressure warnings and
messagesThe tire pressure monitoring warns about loss in
pressure in two stages, depending on the amount
of pressure loss:
Stage 1 – Tire pressure too low message
(3 to 6 psi (0.2 to 0.4 bar) loss in pressure)
Stage 2 – Flat tire warning
(loss in pressure as of 6 psi (0.4 bar))
Warning!
Risk of accident. Tire damage may impair
road safety.
fStop the vehicle at a suitable location if there
is a tire pressure warning or tire pressure mes-
sage. Check the tires for signs of damage and fill or change them if necessary.
Example: If the tire pressure display shows
“– 3 psi”, you must increase the tire pressure by
3psi.
Tires can lose air over time without a tire defect
being present. The tire pressure monitoring will
then issue a corresponding message or warning.
fCorrect the tire pressure.
Message indicating tire pressure lossThis message indicates a pressure loss of be-
tween 3 and 6 psi (0.2 and 0.4 bar) if the wheel
positions have not been identified.
This message appears when the vehicle is station-
ary and the ignition is switched on again.
fThe message is displayed for 10 seconds or

In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for a temperature change
of 50°F (10°C).Tire pressure specificationsThe tire pressure must match the prescribed value
(required pressure).
You can find information on the tire pressure for
cold tires (68°F/20°C):
– In the TIRE PRESSURE menu (filling informa-
tion):
As a deviation from the required pressure for
each wheel if the system has learned the
values.
– In the TIRE PRESSURE menu (filling informa-
tion):
As a required pressure for each axle if the
system has not learned the values.
– On the tire pressure plate in the front left door
aperture for each wheel.
– In this Owner’s Manual
Please observe the chapter “TIRE PRES-
SURES, COLD” on Page 370.Insufficient tire pressure can cause tires to
overheat and thus be damaged – even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.
fPlease observe the chapter “TIRES/WHEELS”
