2010 PORSCHE BOXSTER S engine

2Dear Owner, We would like to thank you for your purchase of a
Porsche Sports car.
Judging by the car you have chosen, you are a mo-
torist of a special breed, and you are probably no
novice when it comes to automobiles.
Remember however, as with any vehicle, you
should take time to familiarize yourself with your
Porsche and its performance characteristics. Al-
ways drive within your own unique capabilities as
a driver and your level of experience with your
Porsche. Ensure that anyone else driving your
Porsche does the same. To prevent or minimize in-
jury, always use your safety belts. Never consume
alcohol or drugs before or during the operation of
your vehicle.
This Owner’s Manual contains a host of useful in-
formation. Please take the time to read this manu-
al before you drive your new Porsche. Become fa-
miliar with the operation of your Porsche car for
maximum safety and operating pleasure. The bet-
ter you know your Porsche, the more pleasure you
will experience driving your new car.
Always keep your Owner’s Manual in the car, and
give it to the new owner if you ever sell your
Porsche. A separate Maintenance Booklet
explains how
you can keep your Porsche in top driving condition
by having it serviced regularly.
A separate Warranty and Customer Informa-
tion Booklet contains detailed information about
the warranties covering your Porsche.
For U.S. only:
If you believe that your vehicle has a fault which
could cause a crash, injury or death, you should
immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to noti-
fying Porsche Cars North America, Inc. (Porsche
Cars N.A.).
If NHTSA receives similar complaints, it may open
an investigation, and if it finds that a safety prob-
lem exists in a group of vehicles, it may order a re-
call and remedy campaign. However, NHTSA can-
not become involved in individual problems be-
tween you and your dealer, or Porsche Cars N.A..
To contact NHTSA, you may call the Vehicle Safety
Hotline toll-free at 1-88 8-327-4236 (TTY: 1-800-
424-9153); go to http://www.safercar.gov; or
write to: Administrator, NHTSA, 400 Seventh
Street, SW., Washington, DC 20590.
You can also obtain other information about motor
vehicle safety from http://www.savercar.gov.
Your car has thousands of parts and components
which have been designed and manufactured in
accordance with Porsche’s high standards of
engineering quality and safety.
Warning!
Any alteration or misuse of the vehicle can
lead to accidents and severe or fatal
personal injuries.
Any alteration of the vehicle may negate or
interfere with those safety features built into
the vehicle. Modifications may be carried out
on your vehicle only if approved by Porsche.
Your Porsche is intended to be used in a safe
manner obeying the local laws and in the
light of driving conditions faced by you, and
in accordance with the instructions provided
in this Owner’s Manual.
f Do not misuse your Porsche by ignoring those
laws and driving conditions, or by ignoring the instructions in this manual. Caution!
The fitting of racing tires (e.g. slicks) for
sporting events is not approved by Porsche.
Very high cornering speeds can be achieved
with racing tires. However, the resulting
transverse acceleration values would jeopar-
dize the adequate supply of oil to the engine.
Porsche therefore will not accept any
warranty or accept any liability for damage
occurring as a result of non-compliance with
this provision.
f Do not fit racing tires (e .g. slicks) for sporting events on your vehicle.

Regularly check your vehicle for signs of
damage.
Damaged or missing aerodynamic compo-
nents such as spoilers or underside panels
affect the driving behavior and therefore
must be replaced immediately.
Your car may have all or some of the components
described in this manual.
Should you have difficulty understanding any of
the explanations of features or equipment installed
in your vehicle, contact your authorized Porsche
dealer. He/She will be glad to assist you. Also
check with your dealer on other available options
or equipment.
Throughout this booklet, left is designated as the
driver’s side of the vehicle, and right as the pas-
senger’s side of the vehicle.
Text, illustrations and specifications in this manual
are based on the informatio n available at the time
of printing.
It has always been Porsche’s policy to continuous-
ly improve its products. Porsche, therefore, re-
serves the right to make changes in design and
specification, and to make additions or improve-
ments in its product without incurring any obliga-
tion to install them on products previously manu-
factured.
We wish you many miles of safe and pleasurable
driving in your Porsche.

your car, please follow all operating instructions
and special warnings. These special warnings use
the safety alert symbol, followed by the words
Danger, Warning and Caution . These special
warnings contain important messages regarding
your safety and/or the potential for damage to
your Porsche. Ignoring them could result in seri-
ous mechanical failure, serious personal injury or
death.
f Do not alter your Porsche. Any alteration could
create dangerous conditions or defeat safety
engineering features built into your car.
f Do not misuse your Porsche. Use it safely, and
consistently with the law, according to the driv-
ing conditions, and the instructions in this man-
ual.
Alteration or misuse of your Porsche could
cause accidents and serious personal injury
or death.

Engine Exhaust
Danger!
Engine exhaust is dangerous if inhaled.
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 en-
closed, unventilated area.
It is not recommended to sit in your car for pro-
longed periods with the engine on and the car not moving.
California Proposition 65 Warning Warning!
Engine exhaust, some of its constituents, and cer-
tain vehicle components contain or emit chemi-
cals known to the State of California to cause can-
cer and birth defects or other reproductive harm.
In addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of California to
cause cancer and birth defects or other reproduc-
tive harm.
Hot Exhaust Pipes
Warning!
Risk of burn injury wh en 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

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.
