Starting - Porsche 928 ST1991 Owner's Manual

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.
• FIRE DANGER. 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.
• If your car catches on fire for any reason,
call the fire department. Do not en-
danger your life by attempting to put out
the fire yourself.
• 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 Neutral.
Automatic transmission:
Move selector lever to Park.
Temperature sensors on the engine automat-
ically provide the correct fuel/air mixture re-
quired 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 tempera-
tures, fully depress the clutch pedal, so that
the starter only has to crank the engine.
As soon as the engine starts, release the ig-
nition key.
If the engine fails to start after 10 to 15
seconds of cranking, wait about 10 sec-
onds 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 en-
gine has reached normal operating tempera-
ture.
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 con-
tact.
• The radiator fan switches on automati-
cally when the coolant reaches a certain
temperature and continues to run (even
with ignition off) until the coolant temp-
erature drops. Therefore, never touch
the fan blades as they will rotate spon-
taneously when the
turns the fan on.
If you have an automatic garage door...
The transistorized ignition system in your
Porsche may interfere with your electroni-
cally 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 au-
tomatic garage door to have the frequency
and/or coding of the garage door signal
modified.
