be used to start the engine.
Please observe the chapter "EMERGENCY
STARTING WITH JUMPER CABLES" on
Page 372.
Note on operation
To ensure a good charge condition for the battery
and thus its ability to start the engine, all electrical
accessories which are not required should be
switched off when the ignition is switched on and
when engine revolutions are low (in stop and go
traffic).
Stopping
f Withdraw the ignition key only when the vehicle
is stationary, otherwise the steering lock en-
gages and the vehicle cannot be steered.
f Only switch the ignition off when the vehicle
comes to a stop, as there is no steering assist-
ance and brake boost when the engine is
switched off.
f Always withdraw the ignition key and engage
the parking brake when leaving the vehicle.
The control unit always remains in the ignition
lock in vehicles that have Porsche Entry &
Drive.
Note on operation
The vehicle battery discharges if the ignition key is
left inserted.
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently.
Radiator fans
The radiator and radiator fans are in the front of
the car.
Warning!
Danger of injury. After the ignition is
switched off, the engine compartment and
coolant temperatures are monitored for ap-
prox. 30 minutes. During this period, and de-
pending on temperature, the radiator fan
may continue to run or start to run.
f Carry out work in these areas only with the en-
gine off and exercise extreme caution.
