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.

174 Driving and Driving Safety
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
14_991_Turbo_21.book Seite 174 Mittwoch, 9. April 2014 2:19 14

Driving and Driving Safety 175
is suppressed because here, the vehicle does not slow down, despite the engine overrun torque and no fuel is consumed in this driving situation due to utilization of the overrun shut-off.
Ending coasting mode/utilizing engine braking effect
fPress the accelerator or brake pedalor Operate a shift paddle or a shift button or Shift gear using the selector lever.
Initiating coasting mode manually
– Driving in selector lever position D or driving in selector lever position M
When coasting mode is suppressed, e.g. in the case of sporty driving, sudden release of the accelerator pedal or excessively low engine temperature, coasting mode can be initiated manually.fTake your foot off the accelerator pedal and shift past the highest possible gear with the shift paddle, one of the shift buttons, or with the selector lever.
Switching coasting mode on and off using the Auto Start Stop button
Switching off
fPress button . The indicator light on the button lights up.Coasting mode is switched off and automatic stopping of the engine is suppressed.
Switching on
fPress button . The indicator light on the button goes out.Coasting mode is switched on and the engine is automatically stopped when the vehicle stops.
“Sport” mode activated
The PDK transmission switches to a sporty gear- changing map and shortens the shifting times.A sporty driving style is recognized more quickly and the gear-changing speeds are adapted to driving performance.
Braking downshifts are initiated earlier. Downshifts occur for small decelerations, even at higher revs.
“Sport Plus” mode activated
In “Sport Plus” mode, the PDK transmission changes to a shift program designed for driving on race circuits. 7th gear is not selected.The gear-changing performance is enhanced significantly again compared with “Sport” mode.fPlease see the chapter ““SPORT” AND “SPORT PLUS” MODE” on page 188.
Driving off with Launch Control
Launch Control allows you to achieve maximum acceleration from standstill.
Launch Control is designed to be used in a controlled environment on closed circuit driving courses where no vehicle cross traffic or pedestrian traffic is present.fUse Launch Control only if conditions permit it to be applied in a safe manner.fDo not use Launch Control if there is a possibility it could endanger other persons.Such a possibility exists if you cannot see that you have a clear road with no possibility of cross traffic in your intended direction of driving.
Information
Stress on components increases dramatically when starting with maximum acceleration in comparison with normal driving off.
Preconditions: – Launch Control should only be used when the engine has reached operating temperature.–“ Sport Plus” mode must be switched on (indicator light on the button comes on and SPORT PLUS appears on the digital speedometer or on the steering wheel).1. Press the brake with your left foot. 2. Quickly press the accelerator down fully (kickdown activated) and hold it.The engine speed will level off at around 5,500 rpm.“ Launch Control activated” is displayed on the multi-function display.Depending on equipment, the “LAUNCH CONTROL” logo appears on the steering wheel.3. Release the brake within a few seconds.
Remaining stationary for a long time with LAUNCH CONTROL can lead to overloading of the transmission.To protect the transmission, the engine power is then reduced and the LAUNCH CONTROL process is cancelled.
In order to drive off, the accelerator must first be fully released.

176 Driving and Driving Safety
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you can change temporarily from automatic selection mode D to manual mode M.
For example: – Shifting down before bends and on entering built-up areas.– Shifting down on downward slopes (engine braking).– Shifting down for brief spurts of acceleration.
The manual selection mode remains engaged: – For cornering (depending on the lateral acceleration) and overrunning.– When the vehicle is stationary (e.g. at a junction).
The system leaves manual selection mode: – automatically after around 6 seconds (unless cornering or overrunning),– after driving off.
Kickdown
The kickdown function is active in selector-lever positions D and M.fFor optimum acceleration, e.g. when overtaking, press the accelerator pedal beyond the full-throttle point (kickdown).
The transmission shifts down depending on the speed of travel and engine speed.Upshifts occur at the highest possible engine speeds.
PDK selector lever
M – Manual selection mode
The currently engaged gear is retained when you change from D to M.
If you change from M to D, the gear-changing map suitable for your current driving style is selected and the appropriate gear is selected.
The selector lever and the two shift buttons in the upper steering wheel spokes or the shift paddles behind these spokes permit comfortable and safe selection of the seven forward gears.
Steering wheel with shift buttons
Shifting up using the selector lever or the shift buttons
fPress the PDK selector lever or shift button on the steering wheel forward.

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.

182 Driving and Driving Safety
Combined operation of PSM and PTV Plus
In order to ensure optimum stabilization of the vehicle, the center differential lock is influenced when PSM interventions occur on vehicles with PTV Plus.
Combined operation of PSM and PTM
In order to ensure optimum stabilization of the vehicle, torque distribution between the front and rear wheels is adapted and the differential lock is influenced when PSM interventions occur on vehicles with PTV Plus.
In the event of a PTM fault, PSM cannot be switched off.If PSM is switched off, it is switched on again automatically.
Automatic brake differential (ABD)
The ABD system controls the front and rear axles separately. If one wheel of an axle starts to spin, it is braked so that the other wheel on the same axle can be driven.
ABD recognizes different driving states, and it features control strategies adapted to these states. In situations in which little propulsive power is required, such as when the vehicle moves off on a level gravel surface, traction control already becomes active at low engine speeds. If a large amount of propulsive power is required, e.g. when driving off on an uphill slope or for rapid acceleration, the ABD system is adapted accordingly.
Anti-slip control (ASR)
The anti-slip control system prevents the wheels from spinning by adjusting the engine power, thereby ensuring good lane-holding ability and stable handling.
Engine drag torque control (MSR)
In conditions of excessive slip, the engine drag torque control system prevents all driven wheels from locking up when the vehicle is overrunning. This is also the case for downshifts on a slippery road.
Steering torque pulse
The steering torque pulse provides the driver with steering assistance when braking on road surfaces with differing friction values.Additional steering forces also assist the driver during counter steering.
Switching off PSM
fPress button for at least 1 second.PSM is switched off after a short delay.The indicator light on the button and the PSM OFF warning light on the instrument panel light up.The warning “ PSM off” appears on the multi-function display in the instrument panel.
When you brake in the ABS control range , the vehicle is stabilized even when PSM is switched off.
One-sided spinning of the wheels is prevented, even with PSM switched off.

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.
For information on warning messages on the multi-function display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.fAdapt your driving style according to the changed conditions.fContact an authorized Porsche dealer.

Driving and Driving Safety 185
Function
The decisive advantage of ABS lies in the driving stability and maneuverability of the vehicle in hazardous situations.
ABS prevents locking of the wheels during full braking, on almost all road surfaces, until just before the vehicle stops.
ABS begins to control the braking process as soon as a wheel shows a tendency to lock.This controlled braking process is comparable with extremely rapid cadence braking.The pulsating brake pedal and a “juddering noise” warn the driver to adapt his driving speed to the road conditions.fIf full braking is necessary, press the brake pedal fully during the whole braking operation, even though the pedal is pulsating. Do not reduce brake pressure.
Warning light USA
Warning light Canada
If the ABS warning light lights up on the instrument panel while the engine is running, the ABS has switched off because of a fault.The warning message “ ABS/PSM failure Adapted driving permitted ” appears on the multi-function display in the instrument panel.
For information on warning messages on the multi- function display: fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
In this case, the braking system will operate without lock prevention , as in vehicles without ABS.fAdapt your driving style to the changed braking behavior.The ABS must be checked by your authorized Porsche dealer in order to prevent the occurrence of further faults with unpredictable consequences.Please contact an authorized Porsche dealer.
The ABS control unit is adjusted for the approved tire dimensions.The use of tires with non-approved dimensions can lead to different wheel speeds, causing ABS to switch off.
Porsche Active Suspension
Management (PASM)
The PASM system actively adjusts the shock absorbers. The adjustable damper system selects the appropriate damping level for each wheel according to the driving situation and driving conditions. Driving safety, agility and comfort are optimized.
Two different chassis setups can be selected at the push of a button:–“ Chassis Normal” –“ Chassis Sport”
In Normal mode the vehicle is in a sporty and comfortable setup.Sport mode offers very sporty shock absorber tuning (e.g. for driving on the race circuit).
In addition to manual mode selection, PASM also adjusts shock absorber tuning for either sporty or comfort driving, depending on the driving situation.
