2009 PORSCHE BOXSTER gear

Shifting Gears
179
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 269.
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
Page 269.

Shifting Gears
Reduced driving programIf there is a fault in the transmission
– Depending on priority, the warning “Transmis-sion emergency run” in white or red lettering or
the warning “Transmission temperature too
high” is displayed on the on-board computer.
Warning “Transmission emergency run” white
– Effects: Restricted gearshift comfort,
Reverse gear may not function.
Remedy:
Have the fault repaired immediately at an
authorized Porsche dealer. Warning “Transmission emergency run”
red
– Effect: 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.
Warning “Transmission temperature too high”
–Effects: “Warning jerks” can be felt when driving off and
the engine power may be restricted.
Remedy:
Do not hold the vehicle with the accelerator on
a hill, for example. Hold the vehicle with the
brake. Reduce engine load. If possible, stop
the vehicle in a suitable place. Allow the engine
to run in selector lever position P or N until the
warning disappears.

Maintenance, Car Care
Fuel Economy Fuel 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 at correct pressure.
f Always monitor your fuel consumption.
f Drive smoothly, avoid abrupt changes in speed
as much as possible.
f Avoid jack rabbit starts and sudden stops.
f Do not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
f Prolonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
f Switch off the engine if stationary for longer
periods. f
Any additional weight carried in the vehicle re-
duces fuel economy. Always keep cargo to a
minimum and remove all unnecessary items.
f Organize your trips to take in several errands
in one trip.
f All electrical accessories contribute to in-
creased fuel consumption.
f Only switch on the air conditioning when neces-
sary.
f Do not drive with the Ro of Transport System
mounted unless you need it.
The EPA estimated 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.
f Please observe all local and national speed
limits.
Operating your Porsche in other
Countries Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental limits of the United States or Canada, there
is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and se-
rious damage to both engine and catalytic con-
verters could result;
– service ma y be inadequa te due to lack of prop- er service facilities, tools or diagnostic equip-
ment;
– replacement parts may not be available or very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about ship-
ping and forwarding requirements, as well as cur-
rent import and customs regulations.

Practical Tips, Emergency Service
237
Changing a wheel
Warning!
Risk of serious personal injury or death. The
car may slip off the jack.
f Make sure that no one is in the vehicle when
jacking up and changing a wheel.
f Always place the car on stable supports if work
has to be carried out under the car.
Risk of damage to the brake discs of the
Porsche Ceramic Composite Brake (PCCB).
f Always screw in both assembly aids when changing a wheel.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not sup-
plied with the car.
Your authorized Porsche dealer will be pleased to
advise you.
1. Apply the handbrake fully and engage 1st gear or PDK selector-lever position P and remove
the ignition key.
2. Switch on the hazard warning lights if neces- sary.
3. Secure the car against rolling away, e.g. by
means of wedges under the wheels on the op-
posite side.
This is particularly important on slopes. 4. Slightly slacken the whee
l bolts of the wheel to
be changed.
5. Lift the car only at the specified jacking points.
6. Raise the car until the wheel lifts off the ground.
Please see the chapter “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM OR GARAGE LIFT”
on Page 242.
7. Remove 1 or 2 wheel bolts (see respective illustration).
8. Screw in assembly aids instead of the wheel bolts.
Screw in assembly aid for
cars
without Porsche
Ceramic Composite Brake
9. Remove the remaining wheel bolts.
Note on operation
f To remove or mount the spacers:
Please see the chapter “SPACERS” on
Page 243.

Brake fluidapprox. 0.4 quarts/0.39 liters; use
only Original Porsche brake fluid
Windshield washer approx. 0.66 U.S. gallons/2.5 liters without headlight washer

Fuel tank Refill volume approx. 16.9 U.S. gallons/64 liters, including approx. 2.6 U.S.gallons/10 liters reserve.
Fuel quality Your engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with
an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured tha t your vehicle will operate
properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), since the engine’s
”Electronic Octane™ knock control“ will adapt the ignition timing, if necessary.
