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

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.

226 Maintenance and Car Care
Undercoating
Additional undercoating or rust protection agents on or near the exhaust system can become too hot when driving and ignite, causing a fire.fDo not apply additional undercoating or rust protection agent on or near the exhaust manifolds, exhaust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite.
How Emission Control Works
When an automobile engine is running, it uses energy generated through the combustion of a mixture of air and fuel. Depending on whether a car is driven fast or slowly or whether the engine is cold or hot, some of the fuel (hydrocarbons) may not be burned completely, but may be discharged into the engine crankcase or exhaust system. Additional hydrocarbons may enter the atmosphere through evaporation of fuel from the fuel tank. These hydrocarbons (HC), when released into the air, contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of nitrogen (NOx) contribute to engine emissions. They, too, are formed during the combustion process and discharged into the exhaust system.
To reduce these pollutants, your Porsche is equipped with a precisely calibrated fuel injection system to assure a finely balanced air/fuel mixture under all operating conditions.
Oxygen sensor
The oxygen sensor, installed in the exhaust pipe continuously senses the oxygen content of the exhaust and signals the information to an electronic control unit. The control unit corrects the air/fuel ratio, so the engine always receives an accurately metered air/fuel mixture.
Crankcase ventilation
Through crankcase ventilation, undesirable emissions from the engine crankcase are not permitted to reach the outside atmosphere. These emissions are recirculated from the crankcase to the air intake system. From here the emissions mix with the intake air and are later burned in the engine.
Catalytic converters
The catalytic converters are efficient “clean-up” devices built into the exhaust system of the vehicle. The catalytic converters burn the undesirable pollutants in the exhaust gas before it is released into the atmosphere.
The exclusive use of unleaded fuel is critically important for the life of the catalytic converters. Therefore, only unleaded fuel must be used.
The catalytic converters will be damaged by:
– Push or tow starting the vehicle, – Misfiring of the engine,– Turning off the ignition while the vehicle is moving,– Driving until the fuel tank is completely empty,– By other unusual operating conditions.fDo not continue to operate your vehicle under these conditions, since raw fuel might reach the catalytic converters. This could result in overheating of the converters. Federal law prohibits use of leaded fuel in this car.
Fuel Economy
Fuel economy will vary depending on where, when and how you drive, optional equipment installed, and the general condition of your car. A car tuned to specifications and correctly maintained, will help you to achieve optimal fuel economy.fHave your vehicle tuned to specifications. Air cleaner should be dirt free to allow proper engine “breathing”.Battery should be fully charged.Wheels should be properly aligned.Tires should be inflated to the correct pressure.

246 Minor Repairs
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.fDo not exceed the permitted maximum speed for the tires fitted to the vehicle.fEnsure that the tires are set to the correct inflation pressure.fObserve the maximum load for the vehicle.
Tire pressures
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires and causes damage. fAlways use an accurate tire pressure gauge when checking inflation pressures.fDo not exceed the maximum tire pressure listed on the tire sidewall. (Also refer to “Technical data”).fPlease see the chapter “TIRE PRESSURE PLATE” on page 247.fCold tire inflation pressure means: all tires must be cold, ambient temperature maximum 68 °F (20 °C), when adjusting the inflation pressure. Avoid sunlight striking the tires before measuring cold pressures, since the pressures would rise from temperature influence.fValve caps protect the valve from dust and dirt, and thus from leakage. Always screw caps tightly down. Replace missing caps immediately.
fUse only plastic valve caps.fFor safety reasons, don't use tire inflating bottles.
fPlease see the chapter “TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)” on page 287.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure tell-tale.
For further information on the tire pressure monitoring:fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
When tires are warm, the tire pressure is increased.fNever let air out of hot tires. This could cause the tire pressure to fall below the prescribed value.
Insufficient tire pressure can cause tires to over- heat and thus be damaged – even invisibly. Hidden tire damage is not eliminated by subsequently correcting the tire pressure.
Overloading
Overloading can lead to dangerous vehicle reactions and long braking distances.fDo not overload your vehicle. Be careful about the roof load. fIf you plan to load the vehicle, first correct the tire pressure. Tire pressure for loaded vehicle can be found on the tire pressure plate and in the chapter technical data.fNever exceed the specified axle load.
