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.

Windshield Wiper / Washer Lever
Warning!
Danger of injury when the windshield wipers
operate unintentionally.
Risk of damage to the windshield and wiper
system.
fAvoid running the wiper blades over a dry wind-
shield to prevent scratching the glass. Spray
washer fluid on the windshield first.
A scratched windshield will reduce visibility.
fAlways loosen wiper blades from frozen glass
before operating wipers to prevent damage to
the wiper motor or blades. fAlways switch off windshield wipers in car
wash to prevent them wiping unintentionally
(intermittent or sensor operation).
fAlways switch off windshield wipers before
cleaning the windshield to avoid unintentional
operation (intermittent or sensor operation).
fDo not operate the headlight washer in car
washes.
fDo not operate headlight washer when it is
frozen.
Front wiper and headlight washer system0 – Windshield wipers off

headlights):
The washer sprays only while low beam or high
beam is switched on.
fBriefly push button A to operate headlight

Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel from escaping to the atmosphere at
extreme high outside temperatures, when driving
abruptly around curves and when the car is parked
at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion.
Washer FluidThe reservoir, with a blue screw cap, is in the lug-
gage compartment, to the rear left. Capacity – Without headlight cleaning system:
approximately 2.6 quarts (2.5 liters).
– With headlight cleaning system:
approximately 6.3 quarts (6.0 liters).
Topping off washer fluidClean water is generally not enough to clean the
windshield and headlights.
Depending on the season, mix the water with win-
ter cleaner giving antifreeze protection or a sum-
mer cleaner. Follow the instructions for the mixing
ratio.
fOnly use cleaner fluids authorized by Porsche.
1. Please note all the information on the refill con-
tainer 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.
If less than 0.52 quarts (0.5 liter) remains, a
warning message appears on the on-board
computer.
fAdd washer fluid.
