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.

Possible distance settingsAutomatic braking to a standstill
If the vehicle in front stops, your vehicle will slow down and come to a stop within the control limits of the system if adaptive cruise control is active.The indicator light lights up on the instrument panel.The vehicle is actively held at a stop.
For information on the HOLD function:fPlease see the chapter “HOLD FUNCTION: DRIVE-OFF ASSISTANT, STANDSTILL MANAGEMENT” on page 184.
Information
– Depending on the traffic flow, e.g. slow moving traffic, stopping is initiated by a slow crawling phase, which brings the vehicle to a standstill.– When adaptive cruise control is operating normally or when the HOLD function is active, the brake pedal may feel different and you may hear hydraulic noises.This behavior is normal for the system. It is not a fault.

Driving and Driving Safety 169
Static and fluttering
When the line-of-sight link between a transmitter and vehicle is blocked by large buildings or mountains, the radio sound may be accompanied with static or fluttering because of the characteristic of FM.
In a similar effect, a fluttering noise is sometimes heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjusting the tone control for greater bass response until the disturbance has passed.
Multipath
Because of the reflecting characteristics of FM, direct and reflected signals may reach the antenna at the same time (multipath) and cancel each other out. As a vehicle moves through these electronic dead spots, the listener may hear a momentary flutter or loss of reception.
Station swapping
When two FM stations are close to each other, and an electronic dead spot, such as static or multipath area, interrupts the original signal, sometimes the stronger second signal will be selected automatically until the original one returns. This swapping can also occur as you drive away from the selected station and approach another station of a stronger signal.
Compact disk player
To avoid damage to compact disk player and disks.fUse only compact disks labeled as shown, having no dirt, damage or warpage.
fNever attempt to disassemble or oil any part of the player unit. Do not insert any object other than a disk into the slot. Remember there are no user-serviceable parts inside the compact disk player.fDo not allow the disk to sustain any fingerprints, scrapes or stickers on the surfaces. This may cause poor sound quality.Hold the disk only on the edge or center hole.fWhen not in use, take the disk out of the player, put the disk back into its case and store it away from dust, heat, damp and direct sunlight.Leaving the disk on the dashboard in the sun can damage the disk.fIf the disk gets dirty, clean the disk by wiping the surfaces from the center to the outside in a radial direction with a soft cloth. Do not use a conventional record cleaner or anti-static record preservative. Disk cleaners are available in audio stores.
Car Telephone and Aftermarket Alarms
Important legal and safety information regarding the use of cellular telephones
Some jurisdictions may prohibit the use of cellular telephones while driving a vehicle. Check the laws and regulations on the use of cellular telephones in the areas where you drive.
Looking away from the road or turning your attention away from your driving to operate a cell phone will sooner or later cause an accident. fDo not attempt to operate a hand-held cell phone while you are driving. Safety is more important than a phone call.
fLearn to operate the hands-free phone, if it is available, before you start driving. Then make use of the hands-free phone at all times.
It is essential to observe the telephone manufacturer’s instructions before operating the telephone.
Any portable telephone or radio transmitter which is used in a Porsche must be properly installed in accordance with the technical requirements of Porsche.
The transmission power must not exceed 10 W.
The devices must possess a type approval for your vehicle and have an “e” symbol.
If you should require equipment with transmission power values greater than 10 W, please consult your authorized Porsche dealer for this purpose. They are familiar with the technical requirements for installing devices of this kind.
The antennas for all radios and telephones with a transmitting antenna must be externally mounted.
The improper installation of radios or telephones or use of a radio or telephone with a transmitting antenna inside the car may cause the warning lights to come on.
Improper installation of such equipment can create a discharged battery or excessive current draw from added equipment.

Porsche Doppelkupplung (PDK)
Porsche Doppelkupplung (PDK) is a seven-speed transmission with an automatic and a manual selection mode.
In automatic selection mode (selector-lever position D), gear changing is automatic. You can change temporarily from automatic to manual mode using the shift buttons on the steering wheel.
In manual selection mode (selector-lever position M), you change gear using the shift buttons or shift paddles on the steering wheel or with the PDK selector lever.
You can change between selector-lever positions D and M as you wish while driving.
Information
fTake care not to operate the shift buttons on the steering wheel inadvertently in either automatic or manual mode, thereby triggering undesired gear changes.
Changing selector-lever position
The selector lever is blocked in the P position when the ignition is switched off.
When the ignition is switched on, the selector lever can be moved from position P and N only when the release button is pressed, and when the brake pedal is pressed.
Release button
The release button ( arrow) in the selector lever prevents the gear from being changed unintentionally.The release button must be pressed when shifting to position R or P.
Starting
The engine can be started only if the brake pedal is depressed and the selector lever is in position P or N.
Driving off
fOnly select the desired position for driving off ( D, M or R) when the engine is idling and the brake pedal is pressed.fSince the vehicle crawls when in gear, do not release the brake until you are ready to drive off.
Driving off on hills
The Drive-Off Assistant assists the driver when driving off on hills. The vehicle is held on the slope for a short time during the change from the brake pedal to the accelerator to facilitate driving off immediately after the brake is released.fPlease see the chapter “HOLD FUNCTION: DRIVE-OFF ASSISTANT, STANDSTILL MANAGEMENT” on page 184.
Stopping
fFor a brief stop, e.g. at traffic lights, leave the selector lever in drive position and hold the vehicle with the brake pedal.fDo not hold the vehicle on a slope using the accelerator. Use the brake pedal or the electric parking brake instead.fBefore leaving the vehicle, always apply the electric parking brake and move the selector lever to position P.
Parking
fGo easy on the accelerator!fWhen parking or maneuvering in a small space, control the speed by careful use of the footbrake.

Ending coasting mode/utilizing engine braking effect
fPress the accelerator or brake pedalor Operate a shift paddle or a shift button or Shift gear using the selector lever.
Initiating coasting mode manually
– Driving in selector lever position D or driving in selector lever position M
When coasting mode is suppressed, e.g. in the case of sporty driving, sudden release of the accelerator pedal or excessively low engine temperature, coasting mode can be initiated manually.fTake your foot off the accelerator pedal and shift past the highest possible gear with the shift paddle, one of the shift buttons, or with the selector lever.
Switching coasting mode on and off using the Auto Start Stop button
Switching off
fPress button . The indicator light on the button lights up.Coasting mode is switched off and automatic stopping of the engine is suppressed.
Switching on
fPress button . The indicator light on the button goes out.Coasting mode is switched on and the engine is automatically stopped when the vehicle stops.
“Sport” mode activated
The PDK transmission switches to a sporty gear- changing map and shortens the shifting times.A sporty driving style is recognized more quickly and the gear-changing speeds are adapted to driving performance.
Braking downshifts are initiated earlier. Downshifts occur for small decelerations, even at higher revs.
“Sport Plus” mode activated
In “Sport Plus” mode, the PDK transmission changes to a shift program designed for driving on race circuits. 7th gear is not selected.The gear-changing performance is enhanced significantly again compared with “Sport” mode.fPlease see the chapter ““SPORT” AND “SPORT PLUS” MODE” on page 188.
Driving off with Launch Control
Launch Control allows you to achieve maximum acceleration from standstill.
Launch Control is designed to be used in a controlled environment on closed circuit driving courses where no vehicle cross traffic or pedestrian traffic is present.fUse Launch Control only if conditions permit it to be applied in a safe manner.fDo not use Launch Control if there is a possibility it could endanger other persons.Such a possibility exists if you cannot see that you have a clear road with no possibility of cross traffic in your intended direction of driving.
Information
Stress on components increases dramatically when starting with maximum acceleration in comparison with normal driving off.
Preconditions: – Launch Control should only be used when the engine has reached operating temperature.–“ Sport Plus” mode must be switched on (indicator light on the button comes on and SPORT PLUS appears on the digital speedometer or on the steering wheel).1. Press the brake with your left foot. 2. Quickly press the accelerator down fully (kickdown activated) and hold it.The engine speed will level off at around 5,500 rpm.“ Launch Control activated” is displayed on the multi-function display.Depending on equipment, the “LAUNCH CONTROL” logo appears on the steering wheel.3. Release the brake within a few seconds.
Remaining stationary for a long time with LAUNCH CONTROL can lead to overloading of the transmission.To protect the transmission, the engine power is then reduced and the LAUNCH CONTROL process is cancelled.
In order to drive off, the accelerator must first be fully released.

fPress the PDK selector lever forward or pull the right shift paddle on the steering wheel back.
Shifting down with selector lever or left “–” shift paddle
fPull the PDK selector lever or left shift paddle on the steering wheel back.
Shift to N – Neutral using the shift paddles
fPull both shift paddles simultaneously and release them again immediately. Transmission in N – Neutral.
The vehicle rolls with the engine disengaged and at idle speed without engine braking effect. The number in the gear indicator goes out and the selector lever position flashes.
Power transmission can be re-established by pulling one of the shift paddles or by actuating the selector lever.
At low speeds approaching standstill, the brake must be actuated in order to establish power transmission.
Fast gear shifting by repeated operation of the selector lever, shift buttons or shift paddles.
You can shift up or down by the corresponding number of gears by quickly operating the selector lever, the shift buttons or the shift paddles several times in succession.
Gear changes that would exceed the upper or lower engine-speed limit are not executed by the control unit.
There is no automatic upshift at the upper engine- speed limit in selector-lever position M. Upshift suppression can be cancelled by kickdown operation. If, for example, the engine-speed limit is reached during overtaking and an automatic upshift does not occur, the transmission shifts up in this case as a result of kickdown operation.fSelect an appropriately low gear on upward and downward slopes.This will ensure optimum use of engine power and engine braking.
Upshift prompt for fuel-economy- optimized driving
The consumption-oriented upshift indicator A in the tachometer at the right beside the digital speed display helps you to develop a fuel-saving driving style.
The upshift indicator lights up – prompting you to shift up to the next-higher gear – depending on the selected gear, engine speed and accelerator pedal position.fChange to the next-higher gear when the upshift indicator lights up.

When PSM is switched off, PSM support is no longer provided in critical driving situations outside the ABS control range. fPSM should always be switched on during “normal” driving.
However, it may be a good idea to switch off PSM temporarily in exceptional situations:– On a loose surface and in deep snow.– When “rocking the vehicle free”.
Information
The vehicle retains its enhanced braking readiness through prefilling of the brake system even when PSM is switched off.
When PSM is switched off, wheel-specific brake interventions and the anti-slip control system (ASR) are also switched off.The automatic brake differential (ABD) remains on.
Switching PSM back on
fPress button . PSM is active immediately.The indicator light on the button and the PSM OFF warning light on the instrument panel go out.The message “ PSM on” appears on the multi-function display in the instrument panel.
“Sport Plus” mode
A sportier setup is obtained when “ Sport Plus” mode is switched on.PSM interventions occur later than in Normal mode. The vehicle can be maneuvered with greater agility at its performance limits, without having to dispense with the assistance of PSM in emergency situations. This helps to achieve optimal lap times, particularly on race circuits and on a dry road surface.
PSM warning light
– The PSM warning light on the instrument panel lights up for a lamp check when the ignition is switched on.– The light indicates a control operation, even when PSM is switched off, e.g. brake control in the event of one-sided wheel spin.– The light – in conjunction with the multi-function display – indicates a fault.The warning message “ PSM failure Consult a workshop Adapted driving permitted ” appears on the multi-function display in the instrument panel.
