Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evas ive action due to the
rapid acceleration that this technology
permits.
f Launch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
f Use Launch Control only if conditions permit it
to be applied in a safe manner. f
Do not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving. Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the engine has reached operating temperature.
– “Sport Plus” mode must be switched on (light- emitting diode in button is on and “SPORT
PLUS” is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully (kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
“Launch Control active” is displayed on the
on-board computer. 3. Release the brake within a few seconds.
Remaining stationary for a long time with
“Launch Control active” can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced an d the “Launch Control
active” process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily fr om automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering built-up areas.
– Shifting down on downward slopes (engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler- ation) and overrunning,
– when the vehicle is stationary (e.g. at a junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless cornering or overrunning),
– after driving off.

Shifting Gears
183
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine speed limit are not executed by the
controller.
There is no automatic upshift at the upper engine
speed limit in selector lever position M. Upshift
suppression can be cancelled by kickdown opera-
tion. If, for example, the engine speed limit is
reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up as a result of kickdown operation.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
In order to shift up au tomatically at the upper
engine speed limit:
f Depress the accelerator pedal beyond the full-
throttle point (kickdown). Failure of the selector lever display on the
instrument cluster
The warning “Transmission emergency run” is
displayed in red on the on-board computer.
–Effect:
No selector lever position is displayed on the
instrument cluster.
Vehicle can be driven only until it comes to a
stop.
Remedy:
It is not possible to continue driving. Immedi-
ately stop the vehicle in a suitable place. Have
the vehicle towed to an authorized Porsche
dealer.
Please see the chapter “TOWING” on
Page 259.
Stoppingf For a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
f Before leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.Parkingf Go easy on the accelerator!
f When parking or manoeuvring in a small
space, control the speed by careful use of the
footbrake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mo de. This prevents gear
changes occurring that could cause wheelspin.Tow-starting, towingf Please see the chapter “TOWING” on

Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C .
f Only use antifreeze authorized by Porsche. Checking coolant level The expansion tank with its filler orifice is located
in the rear luggage comp artment under the serv-
ice flap.
f Check the coolant level regularly.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings.
Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
f Do not open the cap of the expansion tank
while the engine is hot.
f Allow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
f Keep coolant out of children’s reach.
f Also, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open contai-
ner. Coolant can be deadly to pets if consu-
med.
Risk of damage from overflowing coolant.
f Take care while topping off coolant not to soil the luggage compartment or items of luggage.
1. Switch engine off and let it cool. Please see the chapter “COOLING SYSTEM” on

Maintenance, Car Care
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant in
dicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment bl ower is mounted in the
engine compartment.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
f Carry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
f Carry out work in these areas only with the en-gine switched off.
Engine Oil It is important to perform oil changes regularly in
accordance with the intervals specified in the
“Maintenance” booklet.
Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumptio n depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing diluted with fuel or moisture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater.

Maintenance, Car Care
189
If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level checked at every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.Engine Oil Level f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
f Regularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 161.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.3 quarts (1.25 liters).
Each segment of the display corresponds to ap-
prox. 0.42 quart (0.4 liter).
Topping off engine oil
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children’s reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thorough-ly with soap and water. Caution!
Risk of damage from overflowing engine oil.
f Take care while checking and topping up
engine oil not to soil the luggage compartment or items of luggage.
Note
The Check Engine warning light may light up if the
cap of the oil filler opening is opened while the
engine is running.
The oil inlet opening is located in the rear luggage
compartment under the service flap.
1. Measure the oil level and read off the required top-up quantity on the on-board computer.
2. Switch off the engine. 3. Press catch button on the service flap and
open flap.
4. Unscrew the oil filler cap.
5. Add at most 0.5 quarts (0.5 liter) of engine oil at a time.
Never add more engine oil than required
to reach the max. mark.
6. Close oil filler cap until you feel it reach its end position.
7. Measure oil level again with the on-board computer. Switch off the engine.
8. If necessary, repeat the process and add more engine oil as required.
