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.

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.

Emission Control System
In the interest of clean air
Pollution of our environment has become a problem that is of increasing concern to all of us. We urge you to join us in our efforts for cleaner air in controlling the pollutants emitted from the automobile.
Porsche has developed an emission control system that controls or reduces those parts of emissions that can be harmful to our environment. Your Porsche is equipped with such a system.
Porsche warrants the Emission Control System in your new car under the terms and conditions set forth in the Warranty Booklet.
You, as the owner of the vehicle, have the responsibility to provide regular maintenance service for the vehicle and to keep a record of all maintenance work performed. To facilitate record keeping, have services performed by authorized Porsche dealers. They have Porsche trained technicians and special tools to provide fast and efficient service.
To assure efficient operation of the Emission Control System:
fHave your vehicle maintained properly and in accordance with the recommendations described in your Maintenance Booklet. Lack of proper maintenance, as well as improper use of the vehicle, will impair the function of the emission control system and could lead to damage.
fDo not alter or remove any component of the emission control system.fDo not alter or remove any device, such as heat shields, switches, ignition wires, valves, etc., which are designed to protect your vehicle's emission control system. In addition to serious engine damage, this can result in a fire if excess raw fuel reaches the exhaust system.fDo not continue to operate your vehicle if you detect engine misfire or other unusual operating conditions.
Parking
The exhaust system becomes very hot when the engine is running and remains hot for some time after the vehicle is turned off. Flammable material close to the exhaust system could ignite.fDo not park or operate your vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or other flammable materials.fIf your car catches on fire for any reason, call the fire department. Do not endanger your life by attempting to put out the fire.

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.
