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.

Driving and Driving Safety 153
Vehicles without Porsche Ceramic Composite Brake (PCCB)
Even though the brake disks consist of alloyed gray cast iron, they will unavoidably start to corrode if your car is parked for an extended period. The brakes will tend to “rub” as a result.The nature, extent and effects of corrosion depend on the amount of time the vehicle was parked, whether road salt or grit was spread and whether grease-dissolving agents were used in car washes.
If the braking comfort is noticeably impaired, we recommend having the brake system checked by experts at an authorized Porsche dealer.
Brake system function
Your Porsche is equipped with a power assisted hydraulic dual circuit brake system with disk brakes at the front and rear. Both circuits function independently. One brake circuit operates the front left and rear right wheel and the other operates the front right and rear left wheel.
If one brake circuit has failed, the other will still operate. However, you will notice an increased pedal travel when you apply the brakes. Failure of one brake circuit will cause the stopping distance to increase.
Your vehicle is equipped with an emergency function in the extreme event of a complete hydraulic failure of the brake system. If your brake pedal goes all the way to the floor, do not pump the brakes. fPush the brake pedal down firmly and hold it in that position. A mechanical linkage activates the second circuit, and you will be able to bring the vehicle to a stop.fAfter bringing your vehicle to a complete stop, avoid driving the vehicle and instead have it towed to the nearest authorized Porsche dealer for repair.
Brake system warning light
You can check the functionality of the brake system warning light by switching the ignition to the “On” position (position 1) and verifying that the warning light illuminates.
Brake warning light USA
Brake warning light Canada
The warning light in the instrument panel lights up. A message will be displayed on the multi-purpose display of the instrument panel if the brake fluid level is too low, or (if the brake pedal travel has increased) one of the two brake circuits has failed.
A greater braking pressure will be required, stopping distances will be longer and the braking behavior will change, particularly in curves.
With correctly adjusted brakes and a correctly working brake system, the pedal travel to the point of brake application should be 1-3/16 in. to 1-9/16 in. (30 to 40 mm). Whenever the brake pedal travel exceeds this value, have the brake system checked.
Brake pedal
Unsuitable or incorrectly fixed floor mats or objects can reduce the travel of the brake pedal or prevent you applying the brake pedal.fAlways check the movement of the brake pedal before driving and make sure that it is not obstructed by a floor mat or any other object.fSecure the floor mat to prevent it from sliding into positions that could interfere with the safe operation of your vehicle.Your authorized Porsche dealer will be glad to offer you floor mats of the correct size including a securing possibility.
Information
In case one of the two brake circuits fails, increased pedal travel is required to bring your vehicle to a full stop.
