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 297.
The tire pressure monitoring monitors the pres-
sure in the four road wheels and warns the driver 
if the pressure is too low.
The display as well as the settings for tire pres-
sure monitoring are done on the multi-purpose dis-
play 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 risk of a tire failure and resulting 
loss of control. Furthermore, low tire pres-
sure increases rate of wear of the affected 
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, immedi-
ately stop in a suitable place and check the 
tires for damage. If necessary remedy the 
damages with a 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 repair shop immediately and have 
the damages repaired.
The tire pressure will not be monitored by a 
defective tire pressure monitoring.
fTires lose air over time without a tire defect 
being 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 in a suitable place. Check the 
tires for signs of damage and change them if necessary.
Example: If the tire pressure display shows 
„– 3 psi“, you must increase the tire pressure by 
3psi.
Tires 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
