Controls, Safety, Instruments
Dear Porsche OwnerA 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 firstfTurn 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 wash-
er 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 unobstruct-
ed.
fCheck air intake slots and area between en-
gine 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 equipmentIt 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.

In the driver's seat...fCheck operation of the horn.
fPosition 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 prac-
tical, while still maintaining full vehicle control.
fAdjust the inside and outside rear view mirrors.
fBuckle your safety belts.
fCheck operation of the foot and parking brake.
fCheck all warning and indicator lights with igni-
tion on and engine not running.
fStart engine and check all warning displays for
warning symbols.
fNever leave an idling car unattended.
fLock 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.
fAlways have your safety belt fastened.
fAlways drive defensively.
Expect the unexpected.
fUse signals to indicate turns and lane changes.
fTurn on headlights at dusk or when the driving
conditions warrant it.
fAlways keep a safe distance from the vehicle in
front of you, depending on traffic, road and
weather conditions.
fReduce 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.
fAlways observe speed limits and obey road
signs and traffic laws.
fWhen 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 observe the chapter “ENGINE EX-
HAUST” on Page 6.fWhen parked, always set the parking brake.
Move the Tiptronic selector lever to “P“.
On hills also turn the front wheels toward the
curb.
fWhen 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.
fMake it a habit to have the engine oil checked
with every fuel filling.

The warning lights will go out after the parking
brake is fully released.
The warning lights are not an indicator that the
parking brake is fully applied; it is only intended to
be a warning to release the parking brake before
driving the car.
Caution!
A partially engaged brake will overheat the
rear brakes, reduce their effectiveness and
cause excessive wear.
fRelease the parking brake fully.
fWhen parking your car, press down firmly on
the foot pedal.
fMove the selector lever to “P“.
fOn hills also turn the front wheels towards the
curb.
BrakesfMake it a habit to check the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph or
100 km/h, for example, it is not twice but four
times longer than 30 mph or 50 km/h. Tire trac-
tion is also less effective when the roads are wet
or slippery.
fTherefore, always maintain a safe distance
from the car in front of you.Note
Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to cor-
rode if your car is parked for an extended period.
The brakes will tend to “rub“ as a result.
The nature, extent and effects of corrosion de-
pend on the amount of time the vehicle was
parked, whether road salt or grit was spread and
whether grease-dissolving agents were used in
car washes.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.

Controls, Safety, Instruments
Brake system functionYour Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disc
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front left and rear right wheel
and the other operates the front right and rear left
wheel.
If one brake circuit has failed, the other will still op-
erate. However, you will notice an increased pedal
travel when you apply the brakes.Failure of one
brake circuit will cause the stopping distance to in-
crease.
Warning!
Risk of an accident. In the unlikely event of
hydraulic failure of one brake circuit:
fPush the brake pedal down firmly and hold it in
that position. A mechanical linkage activates
the second circuit, and you will be able to bring
the vehicle to a stop.
fAfter bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche deal-er for repair.The warning light in the instrument panel lights up.
A message will be displayed on the multi-purpose
display of the instrument panel if the brake fluid
level is too low, or (if the brake pedal travel has in-
creased) one of the two brake circuits has failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking be-
havior will change, particularly in curves.
With correctly adjusted brakes and a correctly
working brake system, the pedal travel to the
point of brake application should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm. Whenever the brake
pedal travel exceeds this value, have the brake
system checked.
Brake pedal
Warning!
Risk of an accident.
Any obstruction of the brake pedal could in-
crease the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you
floor mats of the correct size including a secur-ing possibility.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your vehi-
cle to a full stop.

Safety notes!
fDo not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
fPlease observe the chapter “TOWING” on
Page 340.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be de-
layed and increased pressure may be required.
fFor this reason, keep further back from the ve-
hicle in front and “dry” the brakes by applying
them at intervals. Make sure that following traf-
fic is not affected.
After a long drive over salted or gritted roads, a
coating may form on the brake discs and pads
that significantly reduces friction and thus braking
action.
fTherefore, clean the brake discs and pads ap-
prox. every 2 weeks with a strong jet of water.
The cleaning effect of automatic car washes is
insufficient.
To prevent corrosion of the brake discs, “brake
them dry” before parking the car.fEven though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a re-
sult.
The nature, extent and effects of corrosion de-
pend on the amount of time the vehicle was
parked, whether road salt or grit was spread
and whether grease-dissolving agents were
used in car washes.
If the braking comfort is noticeably impaired,
we recommend having the brake system
checked by experts at an authorized Porsche
dealer.
fTo relieve the braking system on downhill
stretches, change down to a lower gear in
good time to obtain engine braking.
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Continuous braking overheats the brakes and
reduces the braking effect.
fPlease observe the chapter “BRAKE-FLUID LE-
VEL” on Page 242.

Controls, Safety, Instruments The rain sensor remains switched off if the wiper
lever is already in position 1 when the ignition is
switched on.
To switch the rain sensor on again:
fMove wiper stalk to position 0 and then to
position1 – switching on is confirmed by one
wipe of the windscreen – or
fOperate windscreen washer system 5–
switching on is confirmed by three wipes of the
windscreen – or
fChange the sensitivity of the rain sensor with
four-stage switch A.Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windscreen.
fAdjust switch A downwards –
low sensitivity.
2 – Front windscreen wiper – slow
fMove wiper stalk upwards to the second click.
3 – Front windscreen wiper – fast
fMove wiper stalk upwards to the third click.
At speeds of less than approx. ca. 2.5 mph (4 km/
h), rain sensor operation mode is automatically
activated if the windscreen wiper is switched on. If
you exceed a speed of approx. 5 mph (8 km/h),
the system switches to the pre-selected wiper
level.
4 – Front windscreen wiper – one-touch
operation
fMove wiper stalk downwards. The front wind-
screen wipers go through one wiping cycle.5 – Front windscreen wipers and washer
system
fPull wiper stalk towards the steering wheel.
The washer system sprays and wipes while the
lever is pulled towards the steering wheel.
When the wiper lever is released, a few drying
wipes are executed.
Headlight washer (on vehicles with Bi-Xe-
non headlights):
The washer sprays only while low beam or high
beam is switched on.
To activate the headlight washer system, the
wiper lever must be pulled for a longer period
of time.
The spray duration is limited.
Maintenance note
fIf heavily soiled, repeat wash.
fPersistent dirt (e.g. insect remains) should be
regularly removed.
Please observe the chapter “CAR CARE
INSTRUCTIONS” on Page 256.
Thefront windscreen washer nozzles are heat-
ed when the ignition is on, as a precaution against
freezing.
