Brakes
fMake it a habit to check the operation of your brakes before driving.
Keep in mind that the braking distance increases very rapidly as the speed increases. At 60 mph (100 km/h), for example, it is not twice but four times longer than 30 mph (50 km/h). Tire traction is also less effective when the roads are wet or slippery.fTherefore, always maintain a safe distance from the car in front of you.

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.

154 Driving and Driving Safety
fBefore descending a steep grade, reduce speed and shift the transmission into a lower gear to control speed. fDo not “ride the brakes” by resting your foot on the pedal when not intending to apply brake pressure.fDo not hold the pedal down too long or too often. This could cause the brakes to overheat and lose braking power.
Brake booster
The brake booster assists braking only when the engine is running.
When the car is moving while the engine is not running, or if the brake booster is defective, more pressure on the brake pedal is required to bring the car to a stop.
Moisture, road salt or grit on brakes affects braking. Brakes will dry after a few cautious brake applications.
Driving through water may reduce the traction. Moisture on brakes from road water, car wash, or a coating of road salt or grit may affect braking efficiency.fCautiously apply brakes to test and dry the brakes after exposure to road water, etc.
The brake booster is ready for operation only while the engine is running. If the engine is switched off or there is a defect in the brake booster, much greater force has to be applied to the pedal when braking. fVehicles with defective brakes must not be towed and must be transported on a flat bed.
For information on towing:fPlease see the chapter “TOWING” on page 278.
Brake wear
Your car has excellent brakes, but they are still subject to wear. The rate at which they wear depends on how the brakes are used.fHave the brake system inspected at the intervals recommended in your Maintenance Booklet.
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.
A warning message will be displayed on the multi- purpose display of the instrument panel if the brake pads are worn, excessively.fDo not continue to operate the vehicle.Have your authorized Porsche dealer inspect or replace the brake pads.
For information on warning messages on the multi-purpose display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
Brake pads and brake disks
Wear on the brake pads and brake disks depends to a great extent on the driving style and the conditions of use and therefore cannot be expressed in actual miles on the road.
The high-performance brake system is designed for optimal braking effect at all speeds and temperatures.
Certain speeds, braking forces and ambient conditions (e.g. temperature and humidity) can therefore cause the brakes to “squeal”.
Unsuitable or incorrectly installed floor mats or objects can obstruct the movement of the brake pedal or prevent application of the brake pedal.fDo not obstruct the pedal travel with floor mats or other objects.

Operating principle of adaptive cruise control
No vehicle detected in front – open road driving
Adaptive cruise control operates like a cruise control system. The desired speed that was set is maintained constantly.
Vehicle detected in front – driving in traffic
If a vehicle traveling ahead of you in the same lane is detected as driving slower than the selected desired speed, adaptive cruise control will automatically maintain a set distance from the vehicle in front.
If the vehicle in front stops, adaptive cruise control will slow your vehicle down to a stop provided this is possible within the control limits of the system.Adaptive cruise control actively keeps your vehicle at a standstill.
If the vehicle in front drives off, automatic speed control and distance control can be resumed.
Speed exceeded
The speed of the vehicle can be increased at any time by pressing the accelerator.
If the vehicle is traveling faster than the speed set by adaptive cruise control (ACC), adaptive cruise control is deactivated.The message “ ACC passive” appears on the multi-function display in the instrument panel.The desired speed that was stored is retained.
After releasing the accelerator pedal, the ACC accelerates to the desired speed if there is no vehicle in front and controls the distance if there is a vehicle in front.
For information on the “ ACC passive” status:fPlease see the chapter “OPERATING STATES WHEN ADAPTIVE CRUISE CONTROL IS SWITCHED ON” on page 161.R - Switch adaptive cruise control on/off 1 - Set/increase desired speed 2 - Reduce desired speed 3 - Interrupt (OFF) 4 - Operational readiness on/return to set speed (RESUME)
Using adaptive cruise control
Adaptive cruise control is operated using the control stalk at the bottom left of the steering wheel.
Information
You can intervene manually at any time by pressing the brake or accelerator.
