Steering wheel with shift paddles
Shifting up with selector lever or right “+” shift paddle
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.

180 Driving and Driving Safety
Despite the advantages of transmission and chassis control systems, it is still the driver’s responsibility to adapt his 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.These systems cannot reduce the risk of accidents due to inappropriate speed.fAdapt your driving style, maneuvers and speed to the road and weather conditions, as well as the traffic situation.
Porsche Traction Management
(PTM)
Porsche Traction Management is an active allwheel control system designed to influence longitudinal and lateral dynamics. It is closely linked with the Porsche Stability Management (PSM) system.
The permanently driven rear axle enhances the vehicle’s sporty features. Drive power is distributed fully variably to the front axle, depending on the driving situation.
In conjunction with PSM, the PTM system ensures perfect distribution of power among all four wheels in every driving situation. This improves traction and driving stability and ensures the same high level of agility and dynamic response.
In spite of the advantages of PTM and four-wheel drive, it is still the driver’s responsibility to adapt his 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 PTM or four-wheel drive.Risk of accidents due to inappropriate speed cannot be reduced by PTM or four-wheel drive.
Advantages of PTM
– Clearly perceptible improvement in traction, driving stability and steering ability of the vehicle.– Vehicle is more manageable when driven at its performance limits.– Improved straight-ahead tracking and greater stability.– More sporty vehicle setup while making full use of all the advantages of four-wheel drive.– ASR, ABD and PTV Plus further enhance traction for all wheels.
For information on ASR and ABD:fPlease see the chapter “PORSCHE STABILITY MANAGEMENT (PSM)” on page 181.
For information on current torque distribution between front and rear wheels in the multi-function display:fPlease see the chapter “ALLWHEEL MENU” on page 114.

Driving and Driving Safety 181
Porsche Stability Management
(PSM)
PSM is an active control system for stabilization of the vehicle during extreme driving maneuvers.
PSM makes use of both the automatic brake differential (ABD) and anti-slip regulation (ASR) systems, as well as the functions of the anti-lock brake system (ABS) and engine drag torque control system (MSR).
In spite of the advantages of PSM, it is still the driver’s responsibility to adapt his 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 PSM.Risk of accidents due to inappropriate speed cannot be reduced by PSM.
Advantages of PSM
– Best possible traction and lane-holding ability in all driving situations – even on road surfaces with varying friction.– The system compensates for undesired vehicle reactions (Ferraria effect) when the driver releases the accelerator pedal or brakes on bends. This compensation functions up to the maximum lateral acceleration.– PSM actively helps to stabilize the vehicle if necessary during dynamic driving maneuvers (e.g. rapid steering movements, during lane changes, or on alternating bends).
– Improved braking stability on bends and on different or varying road surfaces.– Improved brake function and shorter stopping distance in the event of emergency braking.
Readiness for operation
PSM is switched on automatically every time you start the engine.
Function
Sensors at the wheels, brakes, steering system and engine continuously measure:– Speed– Direction of travel (steering angle)– Lateral acceleration– Axial acceleration– Rate of turn about the vertical axis
PSM uses these values to determine the direction of travel desired by the driver.PSM intervenes and corrects the course if the actual direction of motion deviates from the desired course (steering-wheel position):It brakes individual wheels as required. If necessary, PSM also influences the engine power or the gear-changing characteristic of Porsche Doppelkupplung (PDK) in order to stabilize the vehicle.
The events below inform the driver of PSM control operations and warn him to adapt his driving style to the road conditions:– PSM warning light on the instrument panel flashes.– Hydraulic noises can be heard.– The vehicle decelerates and steering-wheel forces are altered as PSM controls the brakes.– Reduced engine power.– The brake pedal pulsates and its position is changed during braking.In order to achieve full vehicle deceleration, foot pressure must be increased after the brake pedal has begun vibrating.
Examples of PSM control operations
– If the “front wheels of the vehicle drift” on a bend, the engine power is reduced and the rear wheel on the inside of the bend is braked if necessary.– If the rear of the vehicle swings out on a bend, the front wheel on the outside of the bend is braked.– Brake system prefilling:The brake system is prepared for possible subsequent emergency braking if the accelerator pedal is released suddenly and quickly. The brake system is prefilled and the brake pads are already applied gently to the brake disks.– Brake booster (Hydraulic Brake Assist):In the event of an emergency braking operation where the pedal force is insufficient, a brake booster provides the braking pressure necessary for maximum deceleration at all 4 wheels.

184 Driving and Driving Safety
HOLD function: Drive-Off
Assistant, Standstill Management
The HOLD function, as an assistance function, assists the driver when stopping and driving off on upward slopes.The vehicle is automatically prevented from rolling back away from the desired direction of travel.When the HOLD function is active, the indicator light on the instrument panel comes on.
The vehicle is stopped and prevented from rolling back away from the desired direction of travel even without pressing the brake.
Information
The HOLD function is not available if the PDK selector lever is in position P and N.
If the PDK selector lever is moved while the HOLD function is active, the HOLD function is deactivated.
If the driver’s safety belt is unfastened and the driver’s door is opened while the HOLD function is active, the electric parking brake is activated automatically.
For information on the electric parking brake:fPlease see the chapter “ELECTRIC PARKING BRAKE” on page 151.
The limits set by the physics of driving cannot be overcome, even with the HOLD function. Responsibility for driving off on upward slopes is still the driver’s, despite the HOLD function.Assistance by the HOLD function is not always guaranteed when stopping and driving off on a slippery surface (e.g. on icy or loose surfaces). In this case, the vehicle can slip.fAlways adjust your driving style to the driving conditions and vehicle load. Use the footbrake if necessary.
If the Drive-Off Assistant is not functioning, the driver cannot be assisted when driving off on hills.fHold the vehicle with the footbrake.
If the vehicle comes to a standstill on a steep uphill gradient without operation of the footbrake by the driver, this may result in a certain roll-back before the vehicle is held by the HOLD function. In this situation, the roll-back can be reduced by pressing the footbrake.fAssist holding of the vehicle by increasing the braking force with the footbrake.
Information
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.
ABS Brake System
(Anti-lock Brake System)
In spite of the advantages of ABS, it is still the driver’s responsibility to adapt his 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 ABS.Risk of accidents due to inappropriate speed cannot be reduced by ABS.
ABS helps provide:
– Full steering control The vehicle remains steerable– Good driving stability No skidding due to locked wheels– Optimum braking distance Shorter stopping distance in most cases– Prevention of wheel locking No flat spots on the tires

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.

Driving and Driving Safety 187
This has the following advantages: – Improved traction.– Reduced load change responses when cornering at speed.– Improved driving stability at higher speeds.
PTV Plus changes to a more dynamic map when “ Sport Plus” is switched on.
Porsche Dynamic Chassis Control
(PDCC)
In spite of the advantages of PDCC, it is still the driver’s responsibility to adapt his 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 PDCC.Risk of accidents due to inappropriate speed cannot be reduced by PDCC and PTV Plus.
Porsche Dynamic Chassis Control (PDCC) is a system for roll stabilization of the vehicle body when driving.Driving comfort and driving safety are improved by active intervention of the anti-roll bars on the front and rear axles. Vehicle balance and agility are optimized.
No separate controls are available for the PDCC system.When you select a chassis setup in Porsche Active Suspension Management (PASM) the PDCC system automatically activates the corresponding on-road driving program.
For information on selecting a chassis setup:fPlease see the chapter “PORSCHE ACTIVE SUSPENSION MANAGEMENT (PASM)” on page 185.
Warning message
The warning message “ Fault of the PDCC
stabiliser ” appears on the multi-function display in the instrument panel if there is a system fault.

Dynamic Engine Mounting (PADM)
On vehicles with Sport Chrono package
Dynamic Engine Mounting with variable damping is a system designed to enhance both driving dynamics and driving comfort. Depending on the driving situation, the ideal mounting rigidity and damping is automatically set in the range between an rigid engine-to-body connection (increase in driving dynamics) and decoupling of the engine from the body (increase in driving comfort).
“Sport” mode
When “ Sport” mode is switched on, a more rigid engine-to-body connection is achieved for a sporty driving style.
“Sport Plus” mode
When “ Sport Plus” mode is switched on, an optimal engine-to-body connection is achieved for driving on race circuits.
Warning message
Dynamic engine mounting faults are indicated by a warning message on the multi-function display.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
“Sport” and “Sport Plus” mode
The selectable chassis settings mean that the vehicle can offer various modes for a sportier overall setup.The “ Sport” mode pushes the control systems more in the direction of greater emotionality and performance during every day driving.
In “ Sport Plus” mode, maximum performance is set for race-circuit-like driving:– In “ Sport Plus” mode: PASM (Porsche Active Suspension Management) is automatically changed to “ Chassis Normal” or “Chassis Sport” mode. – In “ Sport Plus” mode: Like PASM, PDCC is switched to the corresponding “ Sport” mode, whereby the rolling movements of the vehicle are reduced further, depending on the selected mode.– The PDK transmission switches to a sporty gear-changing map and shortens the gear shifting times when Sport mode is activated. Gear changes take place faster.– The electronic accelerator pedal reacts sooner, and the engine is more responsive to throttle inputs. When Sport mode is switched on and the vehicle is traveling at a speed of less than 40 km/h (25 mph), this function is activated only after the driver has floored the accelerator pedal or released it briefly.– The rpm limiter characteristic is “harder”. In other words: the engine is immediately throttled when the performance limits are reached (only in manual selection mode on vehicles with PDK).
– PSM (Porsche Stability Management) control is more sporty in “ Sport Plus” mode. PSM interventions are later than in Normal mode. The driver can maneuver the vehicle 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 with a dry road surface.– PADM changes to more sporty maps for the dynamic engine mountings to achieve a stiffer engine-to-body connection.In “ Sport” for a sporty driving style, in “ Sport Plus” mode for race-circuit-like driving. – PTV Plus changes to a more dynamic map when “ Sport Plus” is switched on. – The dynamic cornering light reacts more spontaneously to steering angle changes.– The sports exhaust system is be switched to a sound-optimized mode, but can be switched off separately via the button.The Auto Start Stop function and coasting mode are deactivated.fPlease read the relevant chapters.
Overboost function
On vehicles with Sport Chrono package
When “ Sport” or “Sport Plus” mode is switched on and the accelerator is fully pressed, the boost pressure is temporarily increased by approx. 2 psi (0.15 bar) in the medium engine-speed range and the maximum torque increases.
For information on the torque display:fPlease see the chapter “PERFORMANCE MENU” on page 116.

ParkAssist
When the driver is parking and maneuvering the vehicle, ParkAssist indicates the distance between the vehicle and a large obstacle by means of signal tones.fOn vehicles with front and rear sensors:For information on the ParkAssist visual display, please refer also to the section “PARKASSIST” in the operating instructions for the Porsche Communication Systems PCM/CDR.
ParkAssist is activated automatically when reverse gear is selected and the ignition is on.
If the vehicle has front ParkAssist, this also issues an automatic warning when the distance between the vehicle and an obstacle in front is less – than approx. 40 in./100 cm (acoustically) and approx. 32 in./80 cm (visually).
A warning signal sounds when – the distance between the vehicle and an obstacle at the rear is less than approx. 71 in./180 cm.The ParkAssist visual display appears on the central screen of the Porsche communication system.
Front and rear ParkAssist is not activated: – At a speed of more than approx. 9 mph (15 km/h).– When the electric parking brake is activated.– When the ParkAssist has been switched off with button A in the overhead console with the ignition switched on. The indicator light in button A lights up.
Responsibility for parking and for assessing the risk to persons, children, pets, and small objects around the vehicle lies completely with the driver. fMake sure that no persons (especially small children), animals or obstacles are within the maneuvering area. fIf the continuous tone sounds, stop and do not move your vehicle further in that direction.
Ultrasound sensors
Sensors
The ultrasound sensors A in the rear bumper and the sensors A in the front bumper (depending on vehicle equipment) measure the distance to the closest obstacle:– Range behind the vehicle: approx. 71 in. (180 cm)– Range at the side of the vehicle: approx. 24 in. (60 cm)– Range in front of the vehicle: approx. 47 in. (120 cm)
Obstacles cannot be detected in the “blind” sensor area (above and below the sensors, e.g. objects hanging down or close to the ground).

Maintenance notes
fThe sensors must always be kept free of dust, ice and snow in order to ensure that they are fully functional.fDo not damage sensors by abrasion or scratching.fMaintain sufficient distance when cleaning with high-pressure cleaning equipment.The sensors will be damaged if the pressure is too high.
Signal tones/function
When reverse gear is selected, ParkAssist confirms that it is switched on by issuing a short signal tone .
If the vehicle has front ParkAssist, no signal tone will be issued when reverse gear is selected.Instead, the ParkAssist visual display will appear on the central screen of the Porsche communication system.
A detected obstacle is signaled by an intermittent tone . The intervals decrease as the obstacle is approached.
If the distance drops to less than approx. 12 in. (30 cm), a continuous tone sounds.fSet the radio volume so that the signal tones are not drowned out.
The volume of the signal tones can be changed individually.
For information on changing the signal tone volume:fPlease see the chapter “ADJUSTING PARKASSIST VOLUME” on page 126.
Even when using ParkAssist, the driver is still responsible for taking due care when parking and when assessing obstacles.A continuous tone sounds when there is a risk of collision.fDo not drive rearward any further once a continuous tone sounds.
Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing obstacles (e.g. winter driving, powder snow, clothing made from fabric or fur),– sound-reflecting obstacles (such as glass surfaces and flat painted surfaces),– and very thin obstacles (e.g. thin posts).
Other ultrasound sources (e.g. pneumatic brakes of other vehicles, sweeping machines and jack hammers) can interfere with the detection of obstacles.
