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 put the handbrake on
and put the gearshift lever in neutral or the se-
lector lever in position 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.

Automatic driving light assistantThe driving light assistant is a comfort function.
Your Porsche’s driving light (low beam) is switched
on and off automatically, irrespective of the ambi-
ent brightness.
Despite possible support by the driving light assis-
tant, it is the responsibility of the driver to switch
on the driving light using the conventional light
switch in accordance with the relevant national
regulations.
Activating the headlights using the driving light as-
sistant does not therefore absolve the driver
of responsibility for the correct operation of the
driving light.
The low beam is switched on automatically in the
following situations:
–Dusk
–Darkness
– Travelling through tunnels
– Rain (in conjunction with the rain sensor)
– Highway driving
Note on operation
Fog is not recognised.
fIn the event of fog, the driving light must be
switched on manually.
Warning!
Risk of accident due to driving without lights.
fAlways carefully monitor the automatic driving light control.
Highway function
The light is switched on at speeds of over 87 mph
(140 km/h). If you are travelling slower than
40 mph (65 km/h), the driving light is switched off
after a delay of approx. 2 minutes, if the external
lighting conditions permit.
Rain function
The driving light is switched on after five seconds
of continuous wiper operation.
The driving light is switched off approx. 4 minutes
after the wipers have stopped.
Bi-Xenon main headlights with
dynamically controlled cornering lightThe Bi-Xenon main headlights are equipped with
an additional light in vehicles with a cornering
light. As a result of its particular positioning, the
additional light provides significantly better lane
lighting to the left and right of the main light beam.

A- Instrument lighting knobWhen the light is switched on, the brightness of
the instrument illumination can be adjusted by
turning thumb wheel A.
fPlease observe the chapter “A - BUTTON FOR
DIMMING THE COMFORT LIGHTING” on
Page 151.
Automatic Headlight Beam
AdjustmentVehicles with Bi-Xenon headlights feature
automatic headlight beam adjustment.
When the ignition is switched on, the level of the
headlight beam automatically changes in accor-
dance with the vehicle load. The level of the head-
light beam is automatically kept constant during
acceleration and braking.
Checking operation
1. Switch the low beam on.
2. Switch ignition on.
The light beam first dips all the way down and
is then adapted to the vehicle load. It this test
item is not met, the headlight beam adjustment
system must be checked by an authorized
Porsche dealer.
Instrument Illumination

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
windshield.
fAdjust switch A downwards –
low sensitivity.
2 – Front windshield wiper – slow
fMove wiper stalk upwards to the second click.
3 – Front windshield 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 automat-
ically activated if the windshield 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 windshield wiper – one-touch oper-
ation
fMove wiper stalk downwards. The front wind-
shield wipers go through one wipe cycle.5 – Front windshield wipers and washer sys-
tem
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 IN-
STRUCTIONS” on Page 265.

Towing a trailer
Warning!
Driving with a trailer
fAlways observe the permissible towing capac-
ity, vertical coupling load and rear-axle load.
Please observe the chapter “WEIGHTS” on
Page 363.
fWhen connected, the trailer must always be
horizontal behind the towing vehicle. If neces-
sary, use a trailer with an adjustable drawbar.
fWhen the vehicle is driven in the mountains, the
engine output decreases as altitude increases.
The maximum weights stated are the values at
sea level. The total permissable weight of the
car-trailer combination must therefore be re-
duced by 10% for each increment of 3,280 ft.
(1,000 meters) altitude. A fractional increment
counts as the full 3,280 ft. (1,000 meters).
Please take this into consideration when plan-
ning your route.Distributing the load
fDistribute the load in the trailer so that heavy
objects are as close to the axle as possible.
Always safeguard all objects against slipping
and tie them down securely.
fYou should make the best possible use of the
trailer coupling's rated vertical coupling load
when loading the trailer, but never exceed it.
Tire pressure
fSelect the vehicle tire pressure for full load
when towing a trailer.
fPlease observe the chapter “Tire pressure ta-
bles”.
fCheck the tire pressure of the trailer's wheels
according to the manufacturer's instructions.Door mirrors
fIf the width of the trailer obstructs your view of
the traffic behind the trailer, you must have ad-
ditional door mirrors fitted.
Headlights, lights
fAlways check the headlight adjustment before
driving with a trailer.
If necessary, correct with the headlight beam
adjustment function.
fCheck whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.

Recommended procedure
fDeactivate Low Range.
fClean headlights and tail lights and check them
for signs of damage.
fClean the front and rear lincence plates.
fClean the tire tread with a jet of water and re-
move any foreign objects.
fClean wheels, wheel housings and the under-
body with a jet of water.
fCheck whether the car has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
fAfter off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.fAfter driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake discs, brake
pads, wheels and axle joints and have them
cleaned.
fIf you experience severe vibrations after
driving off road, check the wheels for foreign
substances.
These substances can produce an imbalance
which might be responsible for the vibrations.
Removing these deposits may remedy the
problem.

Water crossingfPlease observe the chapter “GROUND CLEA-
RANCE” on Page 366.
Danger!
Danger of drowning if water enters the vehi-
cle. Risk of damage to the engine and acces-
sories if water penetrates.
fBefore driving through water, check the water
depthA, water speed and the condition of the
surface beneath it.
The water must not be deeper than 20 in./
50 cm (22 in./55.5 cm for vehicles with level
control and height adjustment).
fCheck the door sills and rubber seals before
starting to drive.
fDo not drive through deep or rapidly flowing
water.
Deep or rapidly flowing water, e.g. mountain
streams, can cause the car to deviate from the
desired path.
fAvoid a "bow wave" by driving at an appropriate
speed.
fNever open the doors when driving through wa-
ter.Soiling can impair the braking action.
fCheck and clean the brakes if they have been
soiled.
Danger of steering assistance failing during
a long journey in the water if the drive belt
slips.
fIf the steering assistance fails, more effort will
be required to steer.
Danger of damaging electrical systems
fAvoid driving through salt water.
Notes on operation
fActivate Low Range.
fSwitch the air conditioner off.
fSwitch the headlights off.

Maintenance, Car Care
Changing the brake fluidBrake 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 action.
fTherefore, have the brake fluid changed in ac-
cordance with the change intervals stated in
the booklet “Guarantee and Maintenance”.
The warning light in the instrument panel and the
warning message on the multi-purpose display of
the instrument panel indicate
– indicate the brake level fluid is too low or,
– in conjunction with large pedal travel could in-
dicate a braking-circuit failure.
Note on operation
If the warning lights should light up while driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.
Washer FluidThe washer-fluid reservoir for windshield, rear win-
dow and headlights is located in the engine com-
partment.Warning message on the multi-purpose
displayA message is shown on the multi-purpose display
of the instrument panel if the washer-fluid level is
too low.
In this case, the residual quantity is only around
0.85 quarts (0.8 liter).
fAdd washer fluid at the next opportunity.
Topping off washer fluidThe capacity is approx. 7.9 quarts (7.5 liters).
Clean water is generally not enough to clean the
windows and headlights.
It is advantageous to add a winter cleaner giving
antifreeze protection or a suitable summer clean-
er, depending on the season. Follow the instruc-
tions for the mixture ratio.
fUse only cleaner authorised by Porsche.
1. Please note all the information on the refill
container of the cleaning agent.
2. Open cap of the washer-fluid reservoir.
3. Top up washer fluid and close cap properly.
fDo not use engine coolant anti-freeze or any
other solution that can damage the car’s paint,
in the washer reservoir.
