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.

188 Driving and Driving Safety
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.

Maintenance and Car Care 219
Exercise Extreme Caution when
Working on your vehicle
The engine compartment of any motor vehicle is a potentially hazardous area. If you are not fully familiar with proper repair procedures, do not attempt the adjustments described on the following pages.This caution applies to the entire vehicle.
Many vehicle fluids are highly flammable, e. g. fuel, engine and transmission oil. Fuel vapors can cause an explosion. When a battery is being charged, highly explosive gases can develop.fDo not smoke or allow an open flame around the battery or fuel.Pay attention to sparks, e. g. when coming into contact with cables.Keep a fire extinguisher close at hand.fEnsure that there are no open flames in the area of your vehicle at any time when fuel fumes might be present. Be especially cautious of devices such as hot water heaters which ignite a flame intermittently.fOnly work on your vehicle outdoors or in a well ventilated area.
Refill fluids, e. g. engine oil, brake fluid or coolant are hazardous to health (poisonous, irritant, caustic).fKeep these fluids out of children's reach and dispose of them in accordance with the appropriate State, Local and Federal regulations.fOnly work on your vehicle outdoors or in a well ventilated area.
Engine exhaust is dangerous if inhaled. Engine exhaust fumes have many components which you can smell. They also contain carbon monoxide (CO), which is a colorless and odorless gas.Carbon monoxide can cause unconsciousness and even death if inhaled.fOnly work on your vehicle outdoors or in a well ventilated area.
The engine and surrounding components, exhaust system and coolant become very hot when the engine is running.
The coolant reservoir is pressurized. Careless opening of the coolant reservoir can lead to hot coolant suddenly spraying out.
fTake care when working near hot parts of the vehicle, in particular engine parts and parts of the exhaust system.fBefore working in the engine compartment, always switch the engine off and let it cool sufficiently.fAllow the engine to cool down before opening the cap of the coolant reservoir and protect your hands, arms and face from any possible escape of hot coolant.
Take great care to ensure that hands, fingers, articles of clothing (e. g. ties, sleeves, etc.), necklaces or long hair cannot be caught up by the radiator fans, drive belt or other moving parts.
The radiator fans in the front of the vehicle may be operating or unexpectedly start operating when the engine is switched on.fExercise extreme care that parts of the body, articles of clothing or jewelry do not get caught in the radiator fan, drive belt or other moving parts.fCarry out work in these areas only with the engine off and exercise extreme caution.
When the ignition is on, all cables and wires of the ignition system carry a high voltage.fExercise special care when working on the ignition system.
