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 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.

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.
