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

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.

Engine Oil RecommendationPorsche recommends .
The right oil for your vehicle.1) Generally, you can find details of the
manufacturer approvals on the oil containers or as
a notice displayed by the retailer.
The current approval status is also available from
your Porsche partner.2) SAE viscosity class - Example: SAE 0W - 40
Specification 0W = Visc osity specification for
low temperatures (winter).
Specification 40 = Viscosity specification for
high temperatures.3) For all temperature ranges.4) For the temperature range over --13 °F (--25 °C).Always observe the following points:
– Use engine oils approved
by Porsche only. This
is a precondition for optimum and problem-free
operation of your vehicle.
– Regular oil changes are part of servicing. It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet.
– Oils approved by Porsche can be mixed with each other.
– Porsche engines are designed so that no oil additives may be used.
– A label is located in the engine compartment, which provides you with information on suitable
oil for your engine.
Your Porsche partner will be pleased to
advise you.
Oil changeThe engine oil has to be changed regularly at the
intervals listed in your Maintenance Schedule .
f Please see the chapter “CAPACITIES” on
Page 271.
We recommend that you have the engine oil
changed at your Porsche dealer, who has the re-
quired oils and the necessary filling equipment.
If you suspect an oil leak in the engine have your
dealer check it out immediately.
All current engine oils are compatible with each
other, i.e. when making an oil change it is not nec-
essary to flush the engine if you wish to use a dif-
ferent brand or grade of oil.
Since, however, each brand of oil has a special
composition, you should, if possible, use the
same oil brand if it becomes necessary to top up
between oil changes.
Porsche engines have long intervals between oil
changes. You can make best use of these long oil
change intervals by usin g multigrade oils since
these are largely independent of seasonal fluctua-
tions in temperature.

Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we rec-
ommend you do not take your car to areas or
countries where unleaded fuel may not be availa-
ble. Octane ratings Octane rating indicates a fuel’s ability to resist det-
onation. Therefore, buying the correct octane gas
is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S. Cost of Living Council oc-
tane rating) or AKI ( anti knock index) octane rating
usually displayed on U.S. fuel pumps is calculated
as research octane numb er plus motor octane
number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI
Fuels containing ethanolDo not use any fuels containing more than 10 per-
cent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems oc-
cur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling. Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
f Never carry additional fuel in portable contain-ers in your vehicle.
Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel from escaping to the atmosphere at
extreme high outside temperatures, when driving
abruptly around curves and when the car is parked
at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.
