2014 PORSCHE 911 TURBO inflation pressure

40 Seats, Mirrors and Steering Wheel
The inflation process generates the amount of gas required to fill the airbags at the necessary pressure in fractions of a second.
Airbags help to protect the head and body, while simultaneously damping the motion of the driver and passenger in the impact direction in the event of a frontal impact or side impact.
In order to help provide protection in severe collisions which can cause death and serious injury, airbags must inflate extremely rapidly. Such high speed inflation has a negative but unavoidable side effect, which is that it can and does cause injuries, including facial and arm abrasions, bruising and broken bones. You can help minimize such injuries by always wearing your safety belts.
There are many types of accidents in which airbags are not expected to deploy. These include accidents where the airbags would provide no benefit, such as a rear impact against your vehicle. Other accidents where the airbags are designed not to deploy are those where the risk of injury from the airbag deployment could exceed any protective benefits, such as in low speed accidents or higher speed accidents where the vehicle decelerates over a longer time. Since airbag deployment does not occur in all accidents, this further emphasizes the need for you and your passengers to always wear safety belts.
Your Porsche vehicle is equipped with electronically controlled systems that help to ensure your vehicle operates properly. These systems monitor the operation of various systems and electronically store information that is useful to service technicians when they need to diagnose and repair these systems.
Your vehicle is equipped with crash-sensing and diagnostic devices that may record information at the time of a collision, including whether the airbag and seatbelt pretensioners deployed and whether the safety belt was in use.
To retrieve this information, special equipment is needed and access to the vehicle or feature that stores that data is required. Some states only allow access to such information under restricted circumstances, including: – In response to a request of police or other government office; or – with the consent of the registered owner, or if the vehicle is leased, with the lessee, or – through a discovery process in litigation; or as otherwise permitted or required by law.
Your rights with respect to the information discussed above may vary from state to state. Check your state law for further information.
Advanced airbag
Your vehicle is equipped with occupant sensing for the passenger's seat in accordance with U.S. Federal Motor Vehicle Safety Standard 208. Depending on the weight, body positioning and shape acting on the passenger's seat, the passenger’s airbag will automatically be switched on and off.
Depending on the angle and force of impact, the passenger's airbag which is switched-on will be triggered during a collision.
Precondition for switching the passenger's airbag on and off, depending on weight, body positioning and shape:– Ignition is switched on.
Improper seating can unintentionally impair operation of occupant sensing of the passenger’s airbag.
If the weight of an adult on the passenger's seat is not properly maintained, the passenger's airbag may be switched off.fSelect an upright seat position, and do not support weight on the armrests or center console, or lean out of the window while driving. Always keep feet positioned on the floor in the footwell while driving. Do not put feet on the dashboard or the seat area.

The display as well as the settings for the Tire Pressure Monitoring System take place on the multi-function display.
However, the tire pressure must still be set manually on the wheel.fPlease see the chapter “TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)” on page 287.
Driving the vehicle with low tire pressure increases the risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires.Please note that the Tire Pressure Monitoring System is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of Tire Pressure Monitoring System low tire pressure telltale. Low tire pressure reduces the road safety of the vehicle and destroys the tire and wheel.
Tire Pressure Monitoring System gives a warning about a pressure drop caused by natural diffusion as well as about a gradual loss of pressure caused by foreign objects.Tire Pressure Monitoring cannot warn you about tire damage that occurs suddenly (e.g. flat tire due to abrupt external effects).fWhen a red tire pressure warning appears, stop immediately in a suitable place and check the tires for damage. If necessary, remedy the damage with a tire sealant.fDo not by any means continue to drive with defective tires.
fSealing the tire with tire sealant is only an emergency repair so you can drive to the nearest specialist workshop.The maximum permitted speed is 50 mph (80 km/h) .fDo not drive with tires in which the tire pressure drops again very quickly. In case of doubt, have tires checked by a specialist workshop.fDefective tires must be replaced immediately at an authorized Porsche dealer.Tires must never be repaired under any circumstances.fIf Tire Pressure Monitoring System is defective (e.g. defective wheel transmitter), contact an authorized Porsche dealer immediately and have the damage repaired. The tire pressure will not be monitored at all or will be monitored only partially when Tire Pressure Monitoring System is defective.
For information on warning messages on the multi- purpose display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.fIncomplete entries or selection of the wrong tires on the multi-purpose display affect the accuracy of warnings and messages.The settings in the tire pressure menu must be updated following a wheel change or changes in vehicle loading.fUse only the pressure differences shown in the “ Fill info” display in the Tire pressure menu or from the corresponding tire pressure warning when correcting the tire pressure.fTires can lose air over time without a tire defect being present. A tire pressure warning
will then appear on the multi-purpose display.Check the tire pressure at the next opportunity.
Warning light
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.The TPMS malfunction indicator is combined with the low tire pressure telltale.When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.fAlways check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.fDo not exceed the permitted maximum speed for the tires fitted to the vehicle.fEnsure that the tires are set to the correct inflation pressure.fObserve the maximum load for the vehicle.
Tire pressures
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires and causes damage. fAlways use an accurate tire pressure gauge when checking inflation pressures.fDo not exceed the maximum tire pressure listed on the tire sidewall. (Also refer to “Technical data”).fPlease see the chapter “TIRE PRESSURE PLATE” on page 247.fCold tire inflation pressure means: all tires must be cold, ambient temperature maximum 68 °F (20 °C), when adjusting the inflation pressure. Avoid sunlight striking the tires before measuring cold pressures, since the pressures would rise from temperature influence.fValve caps protect the valve from dust and dirt, and thus from leakage. Always screw caps tightly down. Replace missing caps immediately.
fUse only plastic valve caps.fFor safety reasons, don't use tire inflating bottles.
fPlease see the chapter “TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)” on page 287.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.)

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure tell-tale.
For further information on the tire pressure monitoring:fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
When tires are warm, the tire pressure is increased.fNever let air out of hot tires. This could cause the tire pressure to fall below the prescribed value.
Insufficient tire pressure can cause tires to over- heat and thus be damaged – even invisibly. Hidden tire damage is not eliminated by subsequently correcting the tire pressure.
Overloading
Overloading can lead to dangerous vehicle reactions and long braking distances.fDo not overload your vehicle. Be careful about the roof load. fIf you plan to load the vehicle, first correct the tire pressure. Tire pressure for loaded vehicle can be found on the tire pressure plate and in the chapter technical data.fNever exceed the specified axle load.
