Controls, Instruments
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 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 fTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
fCheck all fluid levels such as windshield
washer and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck, and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unob-
structed.
fCheck air intake slots and area between lug-
gage compartment lid and windshield are free
of snow and ice, so the heater and the wind-
shield wipers work properly. fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe 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.

The warning light in the instrument panel comes
on when the ignition is first turned on and remains
on briefly as a bulb check. If the light does not
come on, have the bulb replaced promptly.
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– refuelling with engine running.
Although the vehicle is usually driveable and will
not require towing, see your dealer for service as
soon as possible.
Caution!
If the Check engine light in the instrument
panel is flashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine light
on could cause damage to the emission con-
trol system. It also could affect fuel economy
and driveability.
fHave the fault remedied at the nearest author-ized Porsche dealer immediately. The central warning light on the instrument panel
lights up if there are warning messages in the
INFO menu.
The messages can be called in the on-board
computer INFO menu:
fPlease observe the chapter “INFO WARNING
MESSAGES” on Page 94.
The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.
fPlease observe the chapter “WARNINGS ON
THE INSTRUMENT PANEL AND THE ON-
BOARD COMPUTER” on Page 105.

Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous 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.
fO 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.
fEnsure 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.
fBefore 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.
fBe 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 selector lever in position P.fIn 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
on the engine-compartment lid.
The engine-compartment blower 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.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
fAlways support your car with safety stands if it
is necessary to work under the car.
fWhen 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. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
fSupplies 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.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
Power measurements Power measurements on dynamometers are not
approved by Porsche.

Brake Fluid Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 178.
fUse only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
fKeep brake fluid out of children’s reach.
fTake care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Checking the brake fluid level The reservoir for the hydraulic braking and clutch
systems is located in the luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the
transparent expansion tank through the
window B.
The fluid level should always lie between the
minimum and maximum marks.A slight decrease in the fluid level due to wear and
automatic readjustment of the disc brakes is
normal.
If, however, the fluid level falls markedly or below
the minimum mark, the braking system may have
developed a leak.
fHave the brake system checked without delay
at an authorized Porsche dealer.
