Exercise Extreme Caution when
Working on your vehicle
The engine compartment of any motor vehicle is a potentially hazardous area. If you are not fully familiar with proper repair procedures, do not attempt the adjustments described on the following pages.This caution applies to the entire vehicle.
Many vehicle fluids are highly flammable, e. g. fuel, engine and transmission oil. Fuel vapors can cause an explosion. When a battery is being charged, highly explosive gases can develop.fDo not smoke or allow an open flame around the battery or fuel.Pay attention to sparks, e. g. when coming into contact with cables.Keep a fire extinguisher close at hand.fEnsure that there are no open flames in the area of your vehicle at any time when fuel fumes might be present. Be especially cautious of devices such as hot water heaters which ignite a flame intermittently.fOnly work on your vehicle outdoors or in a well ventilated area.
Refill fluids, e. g. engine oil, brake fluid or coolant are hazardous to health (poisonous, irritant, caustic).fKeep these fluids out of children's reach and dispose of them in accordance with the appropriate State, Local and Federal regulations.fOnly work on your vehicle outdoors or in a well ventilated area.
Engine exhaust is dangerous if inhaled. Engine exhaust fumes have many components which you can smell. They also contain carbon monoxide (CO), which is a colorless and odorless gas.Carbon monoxide can cause unconsciousness and even death if inhaled.fOnly work on your vehicle outdoors or in a well ventilated area.
The engine and surrounding components, exhaust system and coolant become very hot when the engine is running.
The coolant reservoir is pressurized. Careless opening of the coolant reservoir can lead to hot coolant suddenly spraying out.
fTake care when working near hot parts of the vehicle, in particular engine parts and parts of the exhaust system.fBefore working in the engine compartment, always switch the engine off and let it cool sufficiently.fAllow the engine to cool down before opening the cap of the coolant reservoir and protect your hands, arms and face from any possible escape of hot coolant.
Take great care to ensure that hands, fingers, articles of clothing (e. g. ties, sleeves, etc.), necklaces or long hair cannot be caught up by the radiator fans, drive belt or other moving parts.
The radiator fans in the front of the vehicle may be operating or unexpectedly start operating when the engine is switched on.fExercise extreme care that parts of the body, articles of clothing or jewelry do not get caught in the radiator fan, drive belt or other moving parts.fCarry out work in these areas only with the engine off and exercise extreme caution.
When the ignition is on, all cables and wires of the ignition system carry a high voltage.fExercise special care when working on the ignition system.

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.

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.
