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.

Radiator fan, engine compartment blowers
The engine-compartment blowers are mounted under the engine compartment lid.After the engine is switched off, the engine compartment temperature is monitored for approx. 30 minutes.During this period, and depending on temperature, the engine-compartment blowers may continue to run or start to run.fCarry out work in this area only with the engine off and exercise extreme caution.
The radiators and radiator fans are in the front of the vehicle.The radiator fans in the front of the vehicle may be operating or unexpectedly start operating when the engine is switched on.fCarry out work in these areas only with the engine switched off.fTake great care to ensure that parts of the body, items of clothing or jewelery cannot be drawn in by the radiator fan, engine-compartment blower, drive belt or other moving parts.
Measurements on test stands
Performance test
Performance tests on roller-type test stands are not approved by Porsche.
Brake tests
Brake tests must be performed only on roller-type test stands.
The following limit values must not be exceeded on roller-type test stands: – Test speed 4.7 mph (7.5 km/h)– Test duration 20 seconds
Testing the electric parking brake
Electric parking brake tests on the brake test stand must only be performed with the ignition switched on and with the Porsche Doppelkupplung selector lever in position N. The vehicle switches automatically to brake test stand mode, in which the electric parking brake can be tested.The message “ Electric parking brake in service mode ” appears on the multi-function display in the instrument panel.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire vehicle must be lifted and the wheels must be free to turn.
Engine Oil
It is important to perform oil changes regularly in accordance with the intervals specified in your Maintenance Schedule .
Engine oil consumption
It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the lubricant.
If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1000 km) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an expressway, making it then appear that oil is excessively consumed after driving at high speeds.
If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater.
If the vehicle is driven at a high rate of speed, climatic conditions are warm, and the load is high, the oil should be checked more frequently, as driving conditions will determine the rate of oil consumption.– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts. Therefore, the engine oil should be checked regularly and kept at the required level.– Make it a habit to have the engine oil level checked with every refueling.– The oil pressure warning light is not an oil level indicator. The oil pressure warning light indicates serious engine damage may be occurring when lit, if engine rpm is above idle speed.

fAlways monitor your fuel consumption.fDrive smoothly, avoid abrupt changes in speed as much as possible.fAvoid jack rabbit starts and sudden stops.fDo not drive longer than necessary in the lower gears. Shifting into a higher gear early without lugging the engine will help save fuel.fProlonged “warm up” idling wastes gas. Start the vehicle just before you are ready to drive. Accelerate slowly and smoothly.fSwitch off the engine if stationary for longer periods.fAny additional weight carried in the vehicle reduces fuel economy. Always keep cargo to a minimum and remove all unnecessary items.fOrganize your trips to take in several errands in one trip.fAll electrical accessories contribute to increased fuel consumption.fOnly switch on the air conditioning when necessary.fDo not drive with the Roof Transport System mounted unless you need it.
The EPA estimated miles per gallon (mpg) is to be used for comparison purposes, actual mileage may be different from the estimated mpg, depending on your driving speed, weather conditions and trip length. Your actual highway mileage may be less than the estimated mpg.fPlease observe all local and national speed limits.
Operating Your Porsche in other
Countries
Government regulations in the United States and Canada require that automobiles meet specific emission regulations and safety standards. Therefore, cars built for the U.S. and Canada differ from vehicles sold in other countries.
If you plan to take your Porsche outside the continental limits of the United States or Canada, there is the possibility that:– Unleaded fuel may not be available,– Unleaded fuel may have a considerably lower octane rating. Excessive engine knock and serious damage to both engine and catalytic converters could result,– Service may be inadequate due to lack of proper service facilities, tools or diagnostic equipment,– Replacement parts may not be available or very difficult to get.
Porsche cannot be responsible for the mechanical damage that could result because of inadequate fuel, service or parts availability.
If you purchased your Porsche abroad and want to bring it back home, be sure to find out about shipping and forwarding requirements, as well as current import and customs regulations.
Fuel
When the ignition is on, the fuel level is displayed on the instrument panel.fPlease see the chapter “FUEL GAUGE” on page 90.
fFire, open flame and smoking are prohibited when handling fuel.
Fuel and fuel vapors are hazardous to health.fAvoid contact with skin or clothing, since injury to your skin may occur.fDo not inhale fuel vapors, since they may make you ill and possibly cause death if inhalation is prolonged and occurs in a closed space.
To prevent damage to the emission control system and engine:fNever drive the tank dry.fAvoid high cornering speeds after the warning lights have come on.
fPlease see the chapter “FUEL ECONOMY” on page 226.
Check engine warning light
If the warning lights in the instrument panel come on and remain on while driving, it suggests: – a potential engine control problem and the need for system service or – an improperly fastened tank cap or
refueling with engine running.

230 Maintenance and Car Care
Fuel Recommendations
Your Porsche is equipped with catalytic converters and must use UNLEADED FUEL WITHOUT METALLIC ADDITIVES ONLY .
Your engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with an octane rating of 98 RON/ 88 MON (93 CLC or AKI) . Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle will operate properly on unleaded premium fuels with octane numbers of at least 95 RON/ 85MON (90 CLC or AKI) , since the engine’s “Electronic Octane™ knock control” will adapt the ignition timing, if necessary.
If fuels of less than 95 RON/85 MON (90 CLC or AKI) are used however, this could reduce performance and increase fuel consumption.fAvoid driving at full throttle.
It is important to observe the regular service intervals, and particularly the oil change intervals, specified in the “Maintenance” booklet.
The use of UNLEADED FUEL WITHOUT METALLIC ADDITIVES ONLY is critically important to the life of the catalytic converters. Deposits from leaded fuels or metallic additives will ruin the converters and make them ineffective as an emission control device. Metallic additives can cause serious engine damage.
Cars with catalytic converters have a smaller fuel tank opening, and gas station pumps that dispense unleaded fuel have smaller nozzles. This will prevent accidental pumping of leaded fuel into cars with catalytic converters.
Unleaded fuels may not be available outside the continental U.S. and Canada. Therefore, we recommend you do not take your car to areas or countries where unleaded fuel may not be available.
Information
In some countries the available fuel quality may not meet the requirements of your Porsche vehicle and can result in coking inside or around the injector bores or other serious damage to the engine, fuel system or exhaust system.
In this case, the fuel may be mixed only with the additive sold and recommended by Porsche after consulting your authorized Porsche dealer.
Porsche part number 000 043 206 89.fObserve the instructions and mixture ratios stated on the container.
It is important that the service intervals, particularly the oil change intervals, are observed in accordance with the specifications in the “Maintenance” booklet.
Risk of destruction of the engine, fuel system or exhaust system if non-approved additives are used.fUse only additives approved by Porsche. The use of other additives can result in destruction of the engine, fuel system or exhaust system of your vehicle.
Octane ratings
Octane rating indicates a fuel’s ability to resist detonation. Therefore, buying the correct octane gas is important to prevent engine “damage”.
The RON octane rating is based on the research method. The CLC (U.S. Cost of Living Council octane rating) or AKI ( antiknock index) octane rating usually displayed on U.S. fuel pumps is calculated as research octane number plus motor octane number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than the RON rating:
For example: 95 RON equals 90 CLC or AKI.
Fuels containing ethanol
Do not use any fuels containing more than 15 percent ethanol by volume.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle: – Deterioration of drivability and performance. – Substantially reduced fuel economy. – Vapor lock and non-start problems, especially at high altitude or at high temperature. – Engine malfunction or stalling.
