–“ACC not possible Switch on PSM” Adaptive cruise control is not available because PSM was switched off.For information on Porsche Stability Management (PSM) :fPLEASE SEE THE CHAPTER “PORSCHE STABILITY MANAGEMENT (PSM)” on page 181.–“ ACC off” Adaptive cruise control was deactivated.– “ACC not possible Steering lock too large” The steering is turned too far.
General information
“Sport” and “Sport Plus” Mode
Adaptive cruise control regulates your driving more dynamically in “ Sport” and “Sport Plus” mode.
Exceptions for adaptive cruise control
Adaptive cruise control is not available in the following situations:– If the ignition is switched off.– When PSM is off.– If the driver’s door is opened and the driver’s safety belt is not fastened.– When parking or maneuvering in very tight spaces.– When the electric parking brake is activated.– If the PDK selector lever is in position N , R or P. – On upward or downward slopes of more than 15 %.
If one of these exception situations occurs when adaptive cruise control is switched on, adaptive cruise control will be switched off.A message to this effect appears on the multi-function display.
Warning messages
Overtake request when adaptive cruise control is active (ACC active)
If adaptive cruise control detects that braking assistance is required on the part of the driver, a warning signal sounds and the warning message “ Distance Please brake” appears on the multi- function display.
In this case, the braking power of the adaptive cruise control is not sufficient to prevent a collision.fBrake immediately.
Traffic situations in which vehicles cannot be reliably detected
The radar sensor for adaptive cruise control scans a narrow, cone-shaped area in front of your vehicle.Detection can be limited or unreliable, depending on the traffic situation and the size of the vehicle in front. The system may brake too late or unexpectedly.Stationary vehicles are not detected. The system cannot respond to stationary vehicles.fDrive with extreme care.fSlow down if necessary.
Inadequate braking power during automatic braking by the adaptive cruise control.

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.
Insufficient distanceWARNINGh

172 Driving and Driving Safety
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

Driving and Driving Safety 183
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.

Porsche Torque Vectoring
(PTV Plus)
Functional Description
Despite the advantages of PTV, it is still the driver’s responsibility to adapt his/her driving style and maneuvers in line with road and weather conditions, as well as the traffic situation.
The increased safety that is provided should not induce you to take greater risks with your safety. The limits set by the physics of driving cannot be overcome, even with PTV.Risk of accidents due to inappropriate speed cannot be reduced by PTV.
PTV Plus consists of a control system that performs braking interventions based on driving dynamics to achieve variable drive torque distribution on the rear axle and of an electronically controlled rear differential lock.
PTV Plus improves steering response and precision through gentle braking interventions on the inside rear wheel. This braking action cannot be felt by the driver. The vehicle follows the steering angle of the front wheels more precisely. Understeer is largely prevented in the limit range. This increases the lateral acceleration potential and higher cornering speeds are possible.
The electronically controlled rear differential lock continuously monitors the driving condition of the vehicle and distributes the drive torque to the rear axle as required.

Warning messages
The warning message “ Sport mode not available ” appears on the multi-function display in the instrument panel in the event of a fault.
For information on warning messages on the multi-function display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
Information
After the ignition is switched off, Sport mode is automatically reset to Normal mode.fPlease see the chapter “PORSCHE ACTIVE SUSPENSION MANAGEMENT (PASM)” on page 185.fPlease see the chapter “PORSCHE DYNAMIC CHASSIS CONTROL (PDCC)” on page 187.
Extending Front and Rear Spoilers
The extending spoilers improve driving stability at high speeds.
Spoilers extended manually or as a result of selecting Sport Plus mode do not retract when the vehicle stops.fPlease remember, for example when parking or in multi-storey car parks, that the ground clearance is limited.
Automatic mode
Depending on the vehicle speed and the position of the sun roof, the spoilers extend automatically above approx. 75 mph (120 km/h) and retract again below approx. 50 mph (80 km/h).
If the automatic control system fails, the warning message “ Spoiler loss Reduce speed” appears on the multi-function display.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
Display of the warning message “ Spoiler loss Reduce speed ” indicates failure of the extending spoilers. Driving stability will be adversely affected, for example through increased rear axle lift at higher speeds.fAdapt your driving style and speed to the changed driving behavior.fHave the fault corrected at an authorized Porsche dealer.

Rear Axle Steering
Rear axle steering increases maneuverability and agility with greater vehicle stability and reduces the turning circle of the vehicle by approx. 23.6 in. (0.6 m) compared to a vehicle without rear axle steering. The following techniques are used, depending on the speed:– Up to approx. 30 mph (50 km/h): “opposite-direction steering motion” for greater agility (virtual shortening of wheelbase).– Above approx. 50 mph (80 km/h): “same-direction steering motion” for greater stability (virtual extension of wheelbase).
