Driving and Driving Safety 169
Static and fluttering
When the line-of-sight link between a transmitter and vehicle is blocked by large buildings or mountains, the radio sound may be accompanied with static or fluttering because of the characteristic of FM.
In a similar effect, a fluttering noise is sometimes heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjusting the tone control for greater bass response until the disturbance has passed.
Multipath
Because of the reflecting characteristics of FM, direct and reflected signals may reach the antenna at the same time (multipath) and cancel each other out. As a vehicle moves through these electronic dead spots, the listener may hear a momentary flutter or loss of reception.
Station swapping
When two FM stations are close to each other, and an electronic dead spot, such as static or multipath area, interrupts the original signal, sometimes the stronger second signal will be selected automatically until the original one returns. This swapping can also occur as you drive away from the selected station and approach another station of a stronger signal.
Compact disk player
To avoid damage to compact disk player and disks.fUse only compact disks labeled as shown, having no dirt, damage or warpage.
fNever attempt to disassemble or oil any part of the player unit. Do not insert any object other than a disk into the slot. Remember there are no user-serviceable parts inside the compact disk player.fDo not allow the disk to sustain any fingerprints, scrapes or stickers on the surfaces. This may cause poor sound quality.Hold the disk only on the edge or center hole.fWhen not in use, take the disk out of the player, put the disk back into its case and store it away from dust, heat, damp and direct sunlight.Leaving the disk on the dashboard in the sun can damage the disk.fIf the disk gets dirty, clean the disk by wiping the surfaces from the center to the outside in a radial direction with a soft cloth. Do not use a conventional record cleaner or anti-static record preservative. Disk cleaners are available in audio stores.
Car Telephone and Aftermarket Alarms
Important legal and safety information regarding the use of cellular telephones
Some jurisdictions may prohibit the use of cellular telephones while driving a vehicle. Check the laws and regulations on the use of cellular telephones in the areas where you drive.
Looking away from the road or turning your attention away from your driving to operate a cell phone will sooner or later cause an accident. fDo not attempt to operate a hand-held cell phone while you are driving. Safety is more important than a phone call.
fLearn to operate the hands-free phone, if it is available, before you start driving. Then make use of the hands-free phone at all times.
It is essential to observe the telephone manufacturer’s instructions before operating the telephone.
Any portable telephone or radio transmitter which is used in a Porsche must be properly installed in accordance with the technical requirements of Porsche.
The transmission power must not exceed 10 W.
The devices must possess a type approval for your vehicle and have an “e” symbol.
If you should require equipment with transmission power values greater than 10 W, please consult your authorized Porsche dealer for this purpose. They are familiar with the technical requirements for installing devices of this kind.
The antennas for all radios and telephones with a transmitting antenna must be externally mounted.
The improper installation of radios or telephones or use of a radio or telephone with a transmitting antenna inside the car may cause the warning lights to come on.
Improper installation of such equipment can create a discharged battery or excessive current draw from added equipment.

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
