Active Safety – Porsche “Active Safe”
The adaptive cruise control sensor is used for the Porsche “Active Safe” functions.
These include: – Brake system prefilling Prefilling of the brake system if the radar sensor detects that the vehicle is coming critically close to a moving obstacle in order to bridge the air gaps and improve braking response.– Brake Assist Reduction of the activation threshold of the Brake Assist function if the sensor detects that the vehicle is coming critically close to a moving obstacle.The activation threshold of the Brake Assist function is reduced in three stages, depending on how critical the danger situation is.– Target braking If the radar sensor detects that the vehicle is coming critically close to a moving obstacle and, at the same time, braking power is inadequate, brake pressure can be increased in accordance with the situation, through to full braking if required.
Information
All Porsche “Active Safe” functions are active for speeds of more than 20 mph (30 km/h).
Latent warning (visual)
If the vehicle is driving too close to the vehicle in front for a long time, to avoid a collision if the vehicle in front brakes, a latent warning appears on the multi-function display to warn the driver.fStay further back from the vehicle in front if necessary.
Prewarning (acoustic and visual)
If the radar sensor detects that the vehicle is coming critically close to and is very likely to collide with a moving obstacle in front, an acoustic and visual prewarning is issued. This warns the driver and still allows a collision to be prevented if the driver reacts accordingly.
Risk of collision with the vehicle in front.fBrake immediately.

168 Driving and Driving Safety
Acute warning (acoustic, visual and tangible)
If the driver does not react to the prewarning by braking, this is quickly followed by an acute warning, which involves a braking jolt as well as the acoustic and visual warning.
A braking jolt is felt in the vehicle as a result of a very quick build-up of brake pressure. This alerts the driver to the traffic situation. The driver can still prevent a collision by reacting accordingly in this dangerous situation.
Risk of collision with the vehicle in front.fBrake immediately.
Information
The situations described below lead to the assumption that the driver is driving carefully and the prewarning and acute warning functions are disabled:– The driver drives around tight corners.– The driver is braking.– If the driver accelerates sharply, this action is interpreted as an active driving request (e.g. indicating the driver’s intention to overtake).
Switching Porsche “Active Safe” warnings on/off
The latent warning and prewarning functions are switched off by default. The acute warning function is active. Latent warnings and prewarnings can be activated under “ Prewarning on” on the multi-function display.
The settings remain stored when the ignition is switched on and off.fPLEASE SEE THE CHAPTER “ACTIVE SAFETY – PORSCHE “ACTIVE SAFE”” on page 167.
Car Audio Operation/Tips
For radio operation see your radio manual which is included with your on-board literature.
FM reception
A vehicle is not an ideal place to listen to a radio. Because the vehicle moves, reception conditions are constantly changing. Buildings, terrain, signal distance and noise from other vehicles are all working against good reception. Some conditions affecting FM may appear to be problems when they are not.
The following characteristics are completely normal for a given reception area, and they do not indicate any problem with the radio itself.
Information
Electronic accessories should only be installed by your authorized Porsche dealer.Equipment which has not been tested and approved by Porsche may impair radio reception.
Fading and drifting
FM range is limited to about 25 miles (40 km), except for some high power stations.
If a vehicle is moving away from the desired station's transmitter, the signal will tend to fade and/or drift. This condition is more prevalent with FM than AM, and is often accompanied by distortion.Fading and drifting can be minimized to a certain degree by careful attention to fine tuning or selection of a stronger signal.

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.

If aftermarket systems are installed by non- dealership technicians or outside the selling dealer, problems may result. Installation of aftermarket equipment is not covered under the New Car Warranty. fConsult your authorized Porsche dealer about the installation of non-Porsche approved equipment.
Reception quality
The reception quality of your car telephone will change constantly when you are driving. Interference caused by buildings, landscape and weather is unavoidable. It may become particu-larly difficult to hear when using the hands-free function due to external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an automatic car-wash.
Porsche Communication
Management (PCM)
Setting or operating the multi-function display, radio, navigation system, telephone or other equipment when driving could distract you from the traffic. You could lose control of the vehicle.fOperate the components while driving only if the traffic situation allows you to do so safely.fCarry out any complicated operating or setting procedures only with the vehicle stationary.fIf it is necessary to operate these components while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer to the separate operating instructions before putting the PCM into operation.
When put into operation for the first time, a distance of approx. 3 miles (5 km) must be driven in order for the navigation system to complete the process of fine calibration. The same applies when the tires are changed (e.g. summer/snow tires) or new tires fitted. Full location accuracy is not yet achieved during the fine-calibration process.
If the vehicle has been transported (e.g. ferry, car train), the system may take a few minutes after being switched on before it determines the current location.
Serious tire slip (e.g. spinning wheels on snow) may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may take up to 15 minutes before the navigation system is operational once more.
Satellite radio
You must have the satellite radio activated before you can put it into operation. You will need a contract with a provider in order to use this radio.fRefer to the separate radio operating instructions before putting into operation.

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.

Selector-lever Positions
P – Parking lock
fEngage parking lock only when the vehicle is stationary.If selector-lever position P is flashing in the instrument panel, the parking lock is not engaged. The vehicle can roll away.Shift again from selector-lever position R to P.fActivate the electric parking brake and then engage the parking lock.If selector-lever position P is flashing in the instrument panel, the parking lock is not engaged. The vehicle can roll away.Shift again from selector-lever position R to P.
Vehicles without Porsche Entry & Drive: The ignition key can only be removed in selector- lever position P.
R – Reverse gear
fSelect only if the vehicle is stationary and the brake is applied.
N – Neutral
Selector-lever position N must be selected for towing or in car washes, for example.fOnly select the desired position for driving off ( D, M or R) when the engine is idling and the brake pedal is pressed.
D – Automatic selection mode
Select position D for “normal” driving. The gears are shifted automatically according to the accelerator position and speed.
Depending on the way the vehicle is driven (economical, comfortable or sporty driving style) and on the resistance (e.g. uphill), the gear-changing points are shifted towards higher or lower engine-speed ranges.The accelerator position, driving speed, engine speed, longitudinal and lateral acceleration and the road profile all have an influence on the gear-changing characteristic.
Unwanted upshifts, e.g. when entering bends, are prevented by swiftly releasing the accelerator pedal.
Depending on lateral acceleration, upshifts on bends are not made until the engine-speed limit is reached.
When you brake, and depending on the amount of deceleration, the PDK transmission changes down earlier.For subsequent cornering, the correct gear is engaged when pressure is applied to the brakes before the bend. The bend is taken in the right gear, and when you accelerate out of the bend you do not have to change down.
With a sporty driving style, downshifts are already initiated when the brake pedal is touched lightly. This further enhances a dynamic driving style.
The PDK transmission temporarily changes to the sportiest gear-changing map, i.e. to the highest possible gear-changing points, if the accelerator pedal is pressed quickly. The transmission accordingly shifts down immediately by one or two gears (temporary downshift).
The transmission no longer selects 7th gear at very high driving speeds.
However, if necessary, the gear can be selected manually.
Upshifts and downshifts are avoided as far as possible when PSM is active. In the case of high wheel slip when PSM is switched off, upshifts are prevented until slip is no longer detected.
Driving in coasting mode
Through attentive driving, fuel can be saved in coasting mode. The vehicle rolls with the engine disengaged and at idle speed without engine braking effect.
Preconditions for automatic coasting mode – Driving in selector lever position D – Coasting mode is switched on.Indicator light on the button is off.– Sport and Sport Plus modes are switched off– PSM is active– Cruise control is not active– Engine, transmission and battery are at operating temperature– Calm/economic driving style– Slight uphill or slight downhill gradientsfSlowly take your foot off the accelerator.
The engine is disengaged and runs at idle speed. The vehicle rolls with no engine braking effect. Coasting mode is recognizable by the idle speed indicated on the tachometer.
Information
In the case of a sporty driving or when swiftly releasing the accelerator pedal, coasting mode is suppressed to allow targeted use of the engine braking effect. On more pronounced uphill gradients, “coasting” is also prevented as the coasting phases are very short due to the gradient and no significant fuel savings can be achieved. On more pronounced downhill gradients, coasting
