There are 4 switch positions: 0 Steering locked. All electric circuits wired through the ignition switch are turned off. The ignition key can only be withdrawn in the “0” position. The parking lights can be operated in this position by pushing the turn signal indicator lever up and down (also see “Parking lights”). 1 Steering unlocked. In this position all electric circuits are operational except for the following: turn signals, back-up lights, outside mirror remote control, rear window defogger/defroster and fresh air ventilation. 2 Ignition on, steering unlocked. All electric circuits are operational. With the engine stationary, the central warning light and all individual warning lights located in both combination instruments will light up for at bulb check. If the engine oil level is too low the central warning light will flash. (Lack of engine oil can only be checked with the dipstick, with the engine turned off and with the vehicle on level ground.) 3 The starter is operated by turning the ignition key to the right. As soon as the engine starts, release the key. It will spring back to position “2”. With the engine running, the central and individual warning lights should go out. The STOP LAMP will go out after depressing the brake pedal and the PARK BRAKE light after fully releasing the parking brake (see “Central warning light system”). To conserve battery power, the electric circuits for headlights, rear window defogger/defroster and wiper/washer system are temporarily interrupted during the starting process. The starter should not be operated for more that 10 to 15 seconds at a time. If the engine does not start the first time or stalls at any time, the ignition key must be returned to the “0” position. The non-repeat lock in the switch prevents the starter from being operated when the engine is running and thus from being damaged. To remove the key and to lock the steering, turn the key back to position “0” and pull it out. Turn the steering wheel until it locks. WARNING Never remove key from ignition lock or turn key off while vehicle is moving. The steering wheel will lock, causing loss of control. Gong If you leave the key in the ignition/steering lock, the gong will sound when the driver’s door is opened. This is a reminder to remove the key. For further details see “Starting Procedures” on the following page. Starting Procedures WARNING Fasten safety belts before driving. Never start or let the engine run in an enclosed, unventilated area. Exhaust fumes from the engine contain carbon monoxide, which is a colorless and odorless gas. Carbon monoxide can be fatal if inhaled. Never leave engine idling unattended. An unattended vehicle with a running engine is potentially hazardous. Do not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or other flammable material. Never leave engine idling. When starting engine, be ready to drive immediately. Maintain moderate speed until engine is warm. Manual transmission: Move gearshift lever to Neutal. Automatic transmission: Move selector lever to Park. Temperature sensors on the engine automatically provide the correct fuel/air mixture required for starting. Therefore, it is not necessary to depress the accelerator pedal while starting a cold or a warm engine. When starting at very low outside temperatures, fully depress the clutch pedal, so that the starter only has to crank the engine. As soon as the engine starts, release the ignition key. If the engine fails to start after 10 to 15 seconds of cranking, wait about 10 seconds before engaging starter again. Do not let the engine idle to warm it up. After starting, drive vehicle at moderate speeds and with gradual accelerations. Avoid high rpm and full throttle operation until the engine has reached normal operating temperature. Stopping engine Turn key back to position 0. Do not stop engine immediately after hard or extended driving. Keep engine running at increased idle for about two minutes to prevent excessive heat build-up before turning off engine. WARNING Before you check anything in the engine compartment, let the engine cool down. Hot components can burn skin on contact. The radiator fan switches on automatically when the coolant reaches a certain temperature and continues to run (even with ignition off) until the coolant temperature drops. Therefore, never touch the fan blades as they will rotate spontaneously when the thermostat turns the fan on. If you have an automatic garage door . . . The transistorized ignition system in your Porsche may interfere with your electronically operated garage door. To check this: drive your Porsche close to the garage door and run the engine at different speeds. If the garage door opens or closes without your operating the garage door unit in your car, contact the dealer who installed the automatic garage door to have the frequency and/or coding of the garage door signal modified.
