2010 PORSCHE BOXSTER S brake fluid

Maintenance, Car Care
203
Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the
brochure “Maintenance”. – The warning lights on the instrument panel and
on the on-board computer indicate an insuffi-
cient brake fluid level.
– If the warning light lights up on the instrument
panel and the warning message appears on
the on-board computer in combination with a
larger pedal travel, a brake circuit may have
failed.
If the warning lights should light up when
driving:
f Stop immediately in a suitable place.
f Do not continue driving.
Consult an authorized Porsche dealer.

Car Care Instructions fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
Regular and correct care helps to maintain
the value of your car and is also a
precondition for the New Vehicle Warranty
and the Anti Corrosion Warranty.
Your authorized Porsche dealer has specially
developed car-care products from the
Porsche program available either singly or
as complete car-care sets. They will be
pleased to help you select suitable products.
Whether you use Porsche products or other
commercially available cleaning agents first
make sure of their correct application.
A Porsche that is well-cared for can look like new
for years. It all depends on the amount of care the
owner is willing to give the car.
Warning!
Risk of serious personal injury or damage to
the vehicle or property.
Cleaning agents may be hazardous to your
health.
Most chemical cleaners are concentrates
which require dilution. High concentrations
might cause problems ranging from irritation
to serious injury as we ll as damage to your
vehicle. f
Keep cleaning agents out of reach from chil-
dren.
f Observe all caution labels.
f Always read directions on the container before
using any product. These directions may con-
tain information necessary to avoid personal
injury.
f Do not use fuel, kerosene, naphtha, nail polish
remover or other volatile cleaning fluids. They
may be toxic, flammable or hazardous in other
ways. Only use spot removing fluids in a well
vented area.
f Do not clean the underside of chassis, fend-
ers, wheel covers, etc., without protecting
your hands and arms as you may cut yourself
on sharp-edged metal parts.
Moisture and road salt on brakes may affect brak-
ing efficiency.
f Test the brakes after each vehicle washing.
Decorative film Caution!
Risk of damage due to separation of the
decorative film when cleaning your vehicle with
high-pressure cleaning equipment or steam
cleaners.
f Do not use high-pressure cleaning equipment or steam cleaners for cl eaning decorative film.
High-pressure cleaning units,
steam
cleaners
Warning!
High-pressure cleaning units or steam clea-
ners can damage the following components:
–tires,
– logos, emblems,
– painted surfaces,
– alternator,
– ParkAssist sensors,
– convertible top.
f Please observe the operating instructions from
the unit manufacturer.
f When cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 20 inches (50
cm).
f Never use high-pressure cleaning units or
steam cleaners with a ro und-jet nozzle. A high-
pressure cleaning unit or steam cleaners with
round nozzle will damage your vehicle.
f The tires are particularly susceptible to dam-
age.
f Do not point the cleaning jet directly at any of the aforementioned components.

Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N. f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ig nition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
f Always support your car with safety stands if it
is necessary to work under the car.
Jacks are not suitable for this kind of work.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.

Practical Tips, Emergency Service

Danger!
Driving on worn tires can result in loss of con-
trol of the vehicle an d could cause serious
personal injuries or death.
f Do not drive with worn tires or tires showing
cuts or bruises as they may lead to sudden
deflation and loss of control which could cause
severe personal injury.
f Specialized high performance tires on high
performance sports cars exhibit more wear
than those on a family sedan, or even a high
performance sedan.
Therefore, it is important to check your tire
pressure and condition at least every two weeks.
If you notice that tires are wearing unevenly, con-
sult your Porsche dealer.
Uneven wear may not always be due to improper
wheel alignment. It can be the result of individual
driving habits such as cornering at high speeds. If
the tire pressure is not checked and adjusted
regularly, abnormal tire wear can also occur.
Tire care f Avoid damaging tires and wheel rims.
f If you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle.
f Check tires for uneven wear and damage
before driving off.
f Remove imbedded material.
f Replace worn or damaged tires immediately.
f Keep oil, fuel, brake fluid, etc. away from tires.
f Replace missing valve stem caps.
f Keep tires inflated correctly.
f Wash tires when washing the vehicle. Also
clean inner side of wheels.
f Do not use abrasive cleaners when washing
the wheels.
f Check wheel rims for corrosion.
f Remove road salt, if driving in winter.
Tire damage, puncture High-pressure cleaning units can damage the
tires.
f Please see the chapter “HIGH-PRESSURE
CLEANING UNITS, STEAM CLEANERS” on
Page 213.
f Check tires for imbedded material, cuts, punc-
tures, cracks and bulges (side wall) before driv-
ing off.
In case of tire damage, where it is uncertain wheth-
er there is a break in the ply with all its conse-
quences or tire damage caused by thermal or me-
chanical overloading due to loss of pressure or
any other prior damage, we recommend that the
tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that
the difference in tread depth on one axle must not
exceed 30%.
Handling inconsistencies may result.
f Perform a visual inspection if necessary.
