Starting and Stopping the EnginefPlease observe the chapter “IMMOBILIZER” on
Page 19.
fPlease observe the chapter “EMISSION
CONTROL SYSTEM” on Page 263.
Danger!
Risk of poisoning. Exhaust gas contains
colorless and odorless carbon monoxide
(CO), which is toxic even in low concentra-
tion. Carbon monoxide can cause uncon-
sciousness and even death if inhaled.
fNever start or let the engine run in an en-
closed, unventilated area. It is not recommend-
ed to sit in your car for prolonged periods with
the engine on and the car not moving.
An unattended vehicle with a running engine
is potentially hazardous. If warning lights
should come on to indicate improper opera-
tion, they would go unnoticed.
fNever leave the engine idling unattended.
Danger of fire.
fDo not drive or park your car where combus-
tible materials, such as dry grass or leaves,
can come into contact with the hot exhaust
system.
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.
Starting vehicles with manual
transmissionfOperate footbrake.
fFully depress and hold the clutch pedal.
fPut the gearshift lever in neutral.
fDo not press the accelerator pedal. The engine
control module will provide the correct starting
mixture.
fTurn ignition key to ignition lock position 2.
fDo not operate the starter longer than approx.
10 seconds. If necessary, repeat the starting
procedure after a pause of approx.
10 seconds. Turn the ignition key back to
ignition lock position 3 first.
The first operation of the starter is ended automat-
ically when the engine starts.
If the engine does not start, subsequent starter
operations will not be ended automatically.fDo not warm up the engine when stationary.
Drive off immediately.
Avoid high revolutions and full throttle until the
engine has reached operating temperature.
fIf battery output is insufficient, jump leads can
be used to start the engine.
fPlease observe the chapter “EMERGENCY
STARTING WITH JUMPER CABLES” on
Page 331.
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 swit-
ched off when the ignition is switched on and when
engine revolutions are low (in stop and go traffic).

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).
Starting with auxiliary batteryIf your vehicle is fitted with an additional battery
in the luggage compartment, you have the possi-
bility of starting the engine with the ignition key,
even if the main battery fails.
In vehicles with Porsche Entry & Drive:
1. Remove the Porsche Entry & Drive control unit
from the ignition lock.
Please observe the chapter “REMOVING THE
CONTROL UNIT FROM THE IGNITION LOCK” on
Page 59.
2. Insert the ignition key into the ignition lock and
start the engine as described.
fPlease have the cause of the fault remedied at
an authorized Porsche dealer.

StoppingfWithdraw the ignition key only when the vehicle
is stationary, otherwise the steering lock en-
gages and the vehicle cannot be steered.
fOnly switch the ignition off when the vehicle
comes to a stop, as there is no steering assis-
tance and brake boost when the engine is
switched off.
fAlways 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.
fBefore 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.
fCarry out work in these areas only with the en-gine off and exercise extreme caution.

fPlease observe the chapter “CAPACITIES” on
Page 362.
If the vehicle's inclination changes (e.g. going up-
hill/downhill), minor deviations in the indication
may occur.
Fuel reserve warningWhen the engine is running, the warning light on
the multi-purpose display of the instrument panel
lights up if less than 3 gallons (12 liters) of fuel re-
mains in the tank or the range on remaining fuel
falls below approx. 30 miles (50 km).
fFill up at the next opportunity.
Caution!
A shortage of fuel may cause damage to the
emission control system.
fNever drive the tank dry.
fIf the warning lights have come on, do not take turns at high speed.
fPlease observe the chapter “HOW EMISSION
CONTROL WORKS” on Page 264.

Emission ControlThe emission control system detects malfunctions
early that could, for example, cause increased pol-
lutant emissions or consequential damage.
Faults are indicated by the warning light in the in-
strument panel by being continuously lit or flash-
ing.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a lamp check
and goes out approx. 4 seconds after the engine
starts.The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
The warning light in the instrument panel is lit
continuously after the critical range is left.
fIn order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter) go immediately to the nearest
authorized Porsche dealer to have the fault
diagnosed and rectified.
Caution!
Risk of damage. If the warning light in the in-
strument panel continues flashing even when
you have eased off the accelerator pedal,
the emission control system may overheat.
fStop as soon as possible in a safe place.
Make sure that combustible materials, such as
dry grass or leaves, cannot come into contact
with the hot exhaust system.
fSwitch off the engine.
fContact your nearest authorized Porsche deal-er to have the fault rectified.

Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.
It is not possible to describe all details of the
functions in this Owner's Manual.
The examples clearly demonstrate the functional
principle and clarify the menu structure.
As a rule, you can use the menu items:
MAIN MENU > SETTINGS > FACTORY SETTINGS
to return to the basic factory settings.
fPlease observe the chapter “FACTORY SET-
TINGS” on Page 107.

General informationRange on remaining fuel
The range on remaining fuel is continuously
recomputed while driving based on fuel level,
current consumption and average consumption.
Average speed
The displayed values are based on the distance
travelled since the last reset to “zero”.
Note on operation
Switching the ignition off does not reset the
measurements. Values can thus be collected over
long periods. Disconnecting the vehicle battery
clears the memories.
Further on-board computer functions can be dis-
played in the PCM.
Please follow the separate operating instructions
for PCM.
Main MenufOperate the rocker switch until the basic
screen MAIN MENU is displayed.
