On the road…
fNever drive after you have consumed alcohol or drugs.fAlways have your safety belt fastened.fAlways drive defensively. Expect the unexpected.fUse signals to indicate turns and lane changes.fTurn on headlights at dusk or when the driving conditions warrant it.fAlways keep a safe distance from the vehicle in front of you, depending on traffic, road and weather conditions.fReduce speed at night and during inclement weather.Driving in wet weather requires caution and reduced speeds, particularly on roads with standing water, as the handling characteristics of the vehicle may be impaired due to hydro-planing of the tires.fAlways observe speed limits and obey road signs and traffic laws.fWhen tired, get well off the road, stop and take a rest. Turn the engine off. Do not sit in the vehicle with engine idling. Please see the chapter “ENGINE EXHAUST” on page 4.fWhen parked, always put the electric parking brake on and put the PDK selector lever in position P. On hills also turn the front wheels toward the curb.fWhen emergency repairs become necessary, move the vehicle well off the road. Turn on the emergency flasher and use other warning devices to alert other motorists. Do not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry
grass, brush, spilled fuel or other flammable material.fMake it a habit to check the engine oil with every refueling.
Break in hints for the first
2,000 miles (3,000 kilometers)
The following tips will be helpful in obtaining optimum performance from your new Porsche.
Despite the most modern, high-precision manufacturing methods, the moving parts must still wear in with each other. This wearing-in occurs mainly in the first 2,000 miles (3,000 km).
Therefore:
fPreferably take longer trips.fAvoid frequent cold starts with short-distance driving whenever possible.fAvoid full throttle starts and abrupt stops.fDo not exceed maximum engine speed of 4,200 rpm (revolutions per minute).fDo not run a cold engine at high rpm either in Neutral or in gear.fDo not let the engine labor, especially when driving uphill. Shift to the next lower gear in time (use the most favorable rpm range).fNever lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period.fDo not participate in motor racing events, sports driving schools, etc. during the first 2,000 miles (3,000 kilometers).
There may be a slight stiffness in the steering, gear-shifting or other controls during the break-in period which will gradually disappear.
Break in brake pads and brake disks
New brake pads and disks have to be ”broken in“, and therefore only attain optimal friction when the car has covered several hundred miles or km.The slightly reduced braking ability must be compensated for by pressing the brake pedal harder. This also applies whenever the brake pads and brake disks are replaced.
New tires
New tires do not have maximum traction. They tend to be slippery.fBreak in new tires by driving at moderate speeds during the first 60 to 120 miles (100 to 200 km). Longer braking distances must be anticipated.
Engine oil and fuel consumption
During the break-in period oil and fuel consump-tion may be higher than normal.
As always, the rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate and road conditions, as well as the amount of dilution and oxidation of the lubricant.fMake a habit of checking engine oil with every refueling, add if necessary.

154 Driving and Driving Safety
fBefore descending a steep grade, reduce speed and shift the transmission into a lower gear to control speed. fDo not “ride the brakes” by resting your foot on the pedal when not intending to apply brake pressure.fDo not hold the pedal down too long or too often. This could cause the brakes to overheat and lose braking power.
Brake booster
The brake booster assists braking only when the engine is running.
When the car is moving while the engine is not running, or if the brake booster is defective, more pressure on the brake pedal is required to bring the car to a stop.
Moisture, road salt or grit on brakes affects braking. Brakes will dry after a few cautious brake applications.
Driving through water may reduce the traction. Moisture on brakes from road water, car wash, or a coating of road salt or grit may affect braking efficiency.fCautiously apply brakes to test and dry the brakes after exposure to road water, etc.
The brake booster is ready for operation only while the engine is running. If the engine is switched off or there is a defect in the brake booster, much greater force has to be applied to the pedal when braking. fVehicles with defective brakes must not be towed and must be transported on a flat bed.
For information on towing:fPlease see the chapter “TOWING” on page 278.
Brake wear
Your car has excellent brakes, but they are still subject to wear. The rate at which they wear depends on how the brakes are used.fHave the brake system inspected at the intervals recommended in your Maintenance Booklet.
Brake system warning light
You can check the functionality of the brake system warning light by switching the ignition to the “On” position (position 1) and verifying that the warning light illuminates.
A warning message will be displayed on the multi- purpose display of the instrument panel if the brake pads are worn, excessively.fDo not continue to operate the vehicle.Have your authorized Porsche dealer inspect or replace the brake pads.
For information on warning messages on the multi-purpose display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
Brake pads and brake disks
Wear on the brake pads and brake disks depends to a great extent on the driving style and the conditions of use and therefore cannot be expressed in actual miles on the road.
The high-performance brake system is designed for optimal braking effect at all speeds and temperatures.
Certain speeds, braking forces and ambient conditions (e.g. temperature and humidity) can therefore cause the brakes to “squeal”.
Unsuitable or incorrectly installed floor mats or objects can obstruct the movement of the brake pedal or prevent application of the brake pedal.fDo not obstruct the pedal travel with floor mats or other objects.

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.
