Parking heater faultsInitial start-up following period of non-
utilization
If you have not used the parking heater for several
weeks, the system may require the parking heater
to be switched on several times before it actually
“starts up”.
fPlease take a break of approximately
5 minutes between each individual switch-on
attempt.
Requirement for initial start-up of the
parking heater:
–Cold engine.Have the parking heater checked by an authorized
Porsche dealer in the following cases:
– If the parking heater fails to “start-up” after the
3rd switch-on attempt.
– In the event of faults in the parking heater, no
function symbol appears on the display – only
the remaining running time is shown.
The display flashes on briefly and then goes
completely dark.
– In the event of a serious accident, the parking
heater switches off automatically for safety
reasons.
The parking heater is not ready for operation.
– If the temperature rises, the overheating
protection switches the parking heater off
automatically. The parking heater is not ready
for operation.
– The parking heater is switched off automati-
cally if the voltage is too low. The parking
heater is temporarily unavailable.

Driving and Driving Safety Brake system warning light
You can check the functionality of the brake sys-
tem warning light by switching the ignition to the
“On” position and verifying that the warning light
illuminates.
The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has in-
creased) one of the two brake circuits has failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking
behavior will change, particularly in curves.
With correctly adjusted brakes and a correctly
working brake system, the pedal travel to the
point of brake application should be 1-3/16 in. to
1-9/16 in. (30 to 40 mm). Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could in-
crease the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not
obstructed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you
floor mats of the correct size including a securing possibility.
Note
In case one of the two brake circuits fails,
increased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear to control speed.
fDo not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too
often. This could cause the brakes to get hot and not function properly.

Programming a button on the keypad
Caution!
Risk of damage. When programming a gara-
ge door or gate, the door or gate may open
and close several times in quick succession,
causing the motor to overheat.
fUnplug the garage door or gate during the pro-
gramming procedure to prevent the motor from overheating.
1. Press and hold the desired button on the
keypad until light-emitting diode B starts to
flash slowly (may take up to 20 seconds).
Do not release the button before step 3 has
been completed.2. Hold the original remote control approx.
5–30 cm in front of the marked position C.
Make sure that the battery in the original
remote control is new.
3. Press and hold the button on the original remo-
te control until light-emitting diode B flashes ra-
pidly.
The rapidly flashing LED B confirms that the re-
mote control function has been programmed
successfully.
Only release both buttons when LED B flashes.
4. Press the programmed button on keypad A.
If the light-emitting diode B lights up conti-
nuously after programming, this means that
the system is a fixed-code system. Program-
ming is now completed.
If light-emitting diode B again flashes rapidly
for a short time after programming and then
lights up continuously for approx. 2 seconds,
this means that the system is a changeable-
code system. HomeLink must then be synchro-
nized with the receiver of the garage door ope-
ner after programming.
5. Repeat steps 1 to 4 to program the other
buttons.
Synchronization for changeable-code
systems
1. To synchronize the system:
Press the programming button on the receiver
of the garage door opener.
Afterwards, you usually have approx.
30 seconds to initiate step 2.2. Press the previously programmed button on
the keypad three times (for approx. 1 second).
Changeable-code synchronization is now com-
pleted.
3. Repeat steps 1 to 2 to synchronize other
signals to the other buttons.
Note
fPlease consult an authorized Porsche dealer if
you have not been able to successfully assign
signals to the buttons even though you have
carefully followed the instructions in this
section and the operating instructions for the
original remote control. Your authorized
Porsche dealer also has a list of all compatible
garage door opener systems.
Operating the garage door openerfPress the corresponding button on keypad A.
Light-emitting diode B lights up continuously
during signal transmission with fixed-code
systems.
In the case of signal transmission for change-
able-code systems, light-emitting diode B
repeatedly lights up rapidly for a short time
and then lights up continuously for approx.
2seconds.

Maintenance and Car Care
265
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 or
– 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 EconomyFuel 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.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.fSwitch off the engine if stationary for longer
periods.
fAny additional weight carried in the vehicle
re d u c e s f u e l e c o n o m y. A l w a ys k e e p c a rg o t o a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to
increased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
fDo not drive with the Roof Transport System
mounted unless you need it.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage will probably be less
than the estimated mpg.
fPlease see all local and national speed limits.
