Starting the vehicle
fOperate the footbrake.fMove PDK selector lever to the P or N position.fDo not press the accelerator pedal.The engine control unit will provide the correct starting mixture.fTurn the ignition key or control unit (Porsche Entry & Drive) to ignition lock position 2. The starting process is carried out and completed automatically as soon as ignition lock position 2 (start engine) is reached. The ignition key or control unit is reset automatically to ignition lock position 1 (ignition on).fDo not operate the starter for more than approx. 10 seconds. If necessary, repeat the starting procedure after a pause of approx. 10 seconds. Turn the ignition key back to ignition lock position 0 (initial position) first. The first operation of the starter is ended automatically when the engine starts.If the engine does not start, subsequent starter operations will not be ended automatically.fDo not warm up the engine when stationary. Drive off immediately. Avoid high revs and full throttle until the engine has reached operating temperature.
fIf the vehicle battery power is too weak, the engine can be started with jump leads.
For information on jump-lead starting: fPlease see the chapter “EXTERNAL POWER SUPPLY, EMERGENCY STARTING WITH JUMPER CABLES” on page 273.
Information
To ensure a good battery charge condition, thereby ensuring that the battery will start the engine, all electrical loads that are not required should be switched off when the ignition is switched on and when engine revs are low (in traffic jams, in city traffic or in lines).
Stopping
fOnly remove the ignition key when the vehicle is stationary.fOnly switch the ignition off when the vehicle is stationary, as there is no power steering and brake booster assistance when the engine is switched off.fWhen leaving the vehicle, always remove the ignition key, apply the electric parking brake and engage selector-lever position P. The control unit always remains in the ignition lock on vehicles with Porsche Entry & Drive.
Engine components become very hot when the engine is running.fBefore working on any part in the engine compartment, turn the engine off and let it cool down sufficiently.
The exhaust pipe is hot when the engine is running and remains hot for some time after the vehicle is turned off. fTo prevent injury, make a point of noting where your vehicle’s exhaust pipe is, avoid placing your legs near the exhaust pipe when loading and unloading cargo in the rear, and closely supervise children around the vehicle during time when the exhaust pipe could be hot. A hot exhaust pipe can cause painful skin burns.

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.

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.
