2009 PORSCHE BOXSTER fuel

4Porsche Ceramic Composite Brake
(PCCB)fPlease see the chapter “BRAKES” on Page 56.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause brake noises.
Wear on the different components and braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear
increases considerably when the vehicle is driven
on race tracks or through an aggressive driving
style.
f Please consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.
Setting and operating vehicle
components when driving
Warning!
There is a danger of acci dent if you set or op-
erate the on-board comp uter, radio, naviga-
tion system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
f Operate the components while driving only if
the traffic situation allows you to do so safely.
f Carry out any complicated operating or setting procedures only with the vehicle stationary.
Portable Fuel Containers
Danger!
Portable fuel containers may leak, whether
they are full or partially empty. Fuel leaking
from a portable container carried in your ve-
hicle could, in case of an accident, cause a
fire or explosion, resulting in serious person-
al injury or death.
f Never carry additional fuel in portable contain-ers in your vehicle.
Ground Clearance
Caution!
Risk of damage. The vehicle may touch the
ground as a result of reduced ground clear-
ance.
f Drive carefully and slowly on steep slopes (e.g.
parking lots, curbs, uneven roads, lifting plat-
forms etc.).
fAvoid steep ramps.

Before driving off...
Dear Porsche Owner A lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections.
These engineering and safety features will be
enhanced by you... the safe driver... – who knows his/her car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages.
If in doubt, have these checks performed by your
authorized Porsche dealer.
Before driving off... Check the following items first f Turn the engine off before you attempt any
checks or repairs on the vehicle.
f Be sure the tires are inflated correctly.
Check tires for damage and tire wear.
f See that wheel bolts are properly tightened
and not loose or missing.
f Check engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
f Check all fluid levels such as windshield
washer and brake fluid levels.
f Be sure the vehicle battery is well charged and
cranks the engine properly.
f Check all doors and lids for proper operation
and latch them properly.
f Check, and if necessary replace worn or
cracked wiper blades.
f See that all windows are clear and unob-
structed.
f Check air intake slots and area between lug-
gage compartment lid and windshield. Ensure
that these areas are free of snow and ice, so
the heater and the windshield wipers work
properly. f
If a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
f Child restraint systems will not fit into the
Sports bucket seat.
Do not install a child restraint system in the
Sports bucket seat.
The Sports bucket seat cannot be equipped
with the LATCH system and thus the airbag
system cannot be manually deactivated.
f Check all exterior and interior lights for opera-
tion and that the lenses are clean.
f Check the headlights for proper aim, and if
necessary, have them adjusted.
f Check under the vehicle for leaks.
f Be sure all luggage is stowed securely.
Emergency equipment It is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are:
window scraper, snow brush, container or bag of
sand or salt, emergency light, small shovel, first-
aid kit, etc.

Before driving off...
9
In the driver’s seat... fCheck operation of the horn.
f Position seat for easy reach of foot pedals and
controls.
To reduce the possibility of injury from the
airbag deployment, you should always sit back
as far from the steering wheel as is practical,
while still maintaining full vehicle control.
f Adjust the inside and outside rear view mirrors.
f Buckle your safety belts.
f Check operation of the foot and parking brake.
f Check all warning and indicator lights with
ignition on and engine not running.
f Start engine and check all warning displays for
warning symbols.
f Never leave an idling car unattended.
f Lock doors from inside, especially with chil-
dren in the car to prevent inadvertent opening
of doors from inside or outside.
Drive with doors locked.
On the road... fNever drive after you have consumed alcohol
or drugs.
f Always have your safety belt fastened.
f Always drive defensively.
Expect the unexpected.
f Use signals to indicate turns and lane changes.
f Turn on headlights at dusk or when the driving
conditions warrant it.
f Always keep a safe distance from the vehicle in
front of you, depending on traffic, road and
weather conditions.
f Reduce speed at night and during inclement
weather.
Driving in wet weather requires caution and re-
duced speeds, particularly on roads with
standing water, as the handling characteristics
of the vehicle may be impaired due to hydro-
planing of the tires.
f Always observe speed limits and obey road
signs and traffic laws.
f When tired, get well off the road, stop and take
a rest. Turn the engine off. Do not sit in the ve-
hicle with engine idling.
Please see the chapter “ENGINE EXHAUST” on
Page 5. f
When parked, always set the parking brake.
Move the PDK selector le ver to ”P“ or the gear-
shift lever to reverse or first gear.
On hills also turn the front wheels toward the
curb.
f When emergency repairs become necessary,
move the vehicle well off the road. Turn on the
emergency flasher and use other warning de-
vices to alert other motorists. Do not park or
operate the vehicle in areas where the hot ex-
haust system may come in contact with dry
grass, brush, fuel spill or other flammable ma-
terial.
f Make it a habit to have the engine oil checked
with every refueling.

Before driving off...
Break in hints for the first
2,000 miles/3,000 kilometers The following tips will be helpful in obtaining opti-
mum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, the moving parts must still wear
in with each other. This we aring-in occurs mainly in
the first 2,000 miles/3,000 kilometers.Therefore: f Preferably take longer trips.
f Avoid frequent cold starts with short-distance
driving whenever possible.
f Avoid full throttle starts and abrupt stops.
f Do not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
f Do not run a cold engine at high rpm either in
Neutral or in gear.
f Do not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
f Never lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period. f
Do not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles/3,000 kilometers.
There may be a slight stiffness in the steering,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and brake discsNew brake pads and discs ha ve to be “broken in”,
and therefore only attain optimal friction when the
car has covered several hundred miles or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenev er the brake pads and
brake discs are replaced. New tires New tires do not have maximum traction. They
tend to be slippery.
f Break in new tires by driving at moderate
speeds during the first 60 to 120 miles/100 to
200 km. Longer braking distances must be an-
ticipated.
Engine oil and fuel consumption During the break-in peri od oil and fuel consump-
tion may be higher than normal.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road con-
ditions, as well as the amount of dilution and oxi-
dation of the lubricant.
f Make a habit of checking engine oil with every
refueling, add if necessary.

Operation, Safety

Sport ModeA sportier car set-up is obtained when Sport mode
is switched on. Interventions by the Porsche
control systems are intentionally shifted towards
greater agility and driving performance:
– PASM (Porsche Active Suspension Manage-ment) is automatically changed to Sport mode,
resulting in a stiffer suspension setup.
– When Sport mode is active, the PDK transmis- sion switches to a sporty gear-changing map
and shortens the gear shifting times. Gear
changes take place faster, but fuel consump-
tion is also increased.
PSM (Porsche Stability Management) control
gives a sportier road-feel to the vehicle. PSM
interventions take place later than in Normal
mode. The driver can maneuver the vehicle
with greater agility at its performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on, this function is ac tivated only after the
driver has floored the accelerator pedal or
released it briefly.
– The rpm limiter characteristic is “harder”, i.e. the engine is immediately throttled when the
performance limits are reached (only in manual selection mode for vehicles with PDK transmis-
sion).
f Please observe the chap ters on PSM, PASM
and PDK.
Switching Sport mode on and offSwitching Sport mode on and off simultaneously
activates and deactivate s the Sport mode in
PA S M .
If PASM Sport mode was activated with the PASM
button, PASM remains active.
After the ignition is switched off, Sport mode is
automatically reset to Normal mode.
SPORT button
f Press SPORT button A in the center console.
When Sport mode is switched on, the light-
emitting diode in the SPORT button is lit.
A sporty gear-changing map is enabled and the
gear shifting times ar e shortened for the PDK
transmission.
A sporty driving style is recognized more quickly
and the gear-changing speeds are adapted to
driving performance.
Deceleration downshifts are commenced earlier.
Downshifts are made during slight decelerations,
even at higher engine speeds.
f Please see the chapter “SPORT MODE
(“SPORT” AND “SPORT PLUS” MODES)” on
Page 176. SPORT PLUS button
(only on vehicles with PDK transmission)
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.
f
Please see the chapter “SPORT MODE
(“SPORT” AND “SPORT PLUS” MODES)” on
Page 176.
f Press SPORT PLUS button B in the center
console.
When Sport mode is switched on, the light-
emitting diode in the SP ORT PLUS button is lit.

Starting Procedures fPlease see the chapter “IMMOBILIZER” on
Page 15.
f Please see the chapter “EMISSION CONTROL
SYSTEM” on Page 208.
Warning!
Serious injury or death may result if you are
involved in a collision without having fas-
tened the safety belts.
f Fasten safety belts before driving away. Before starting the engine fApply the footbrake.
f Manual transmission:
Fully depress the clutch pedal and put the gear-
shift lever into neutral.
The clutch pedal must be depressed fully
before the starter will engage.
f In vehicles with PDK transmission:
Move PDK selector lever to position P or N.
Temperature sensors on the engine automatically
provide the correct fuel/air mixture required for
starting.
Therefore, it is not necessary to depress the
accelerator pedal while starting a cold or a
warm engine.
Starting the enginef Turn ignition key to ignition lock position 2.
f As soon as the engine st arts, release the igni-
tion key.
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.
If the engine fails to start after 10 or 15 seconds
of cranking:
f Wait about 10 seconds before engaging the
starter again.
f When starting the engine, be ready to drive
immediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
f Do not let the engine idle to warm up.
Danger!
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
f Never start or let the engine run in an
enclosed, unventilated area.
It is not recommended 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 shoul d come on to indicate
improper operation, they would go unno-
ticed.
f Never leave the engine idling unattended.
Danger of fire.
f Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
f If your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put
out the fire.
Risk of burn injury when standing near or coming
into contact with the exhaust pipe.
The exhaust pipe is hot when the vehicle is running
and remains hot for some time after the vehicle is
turned off.
f To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe, and closely
supervise children around the vehicle when the
exhaust pipe could be hot.
A hot exhaust pipe can cause serious burns.
