Controls, InstrumentsIf the ignition key is withdrawn and the door is
opened while the lights (not the parking light or
Welcome Home lighting) are on, a chime warns of
possible battery discharge.
In some countries, differences are possible
due to provisions of law.
Note on operation
Further individual light functions (e.g. daytime driv-
ing lights) are available in vehicles with the Sport
Chrono package.
Please observe the chapter “Individual Memory” in
the separate PCM operating instructions.
Welcome Home LightingSwitching onfMove light switch to the HOME position.
For improved visibility and security when you get
in and out of the car, the fog lights and the tail
lights remain on for a certain period of time:
–When you get out of the car, the lights are
turned on for approx. 30 seconds after the
door is opened. The off-delay time resumes
when the vehicle is locked.
On vehicles with the Sport Chrono package,
the PCM can be used to set the off-delay time.
This setting also changes the lighting period
for unlocking the vehicle.
Please observe the chapter “Individual
Memory” in the separate PCM operating
instructions.
The lights are turned on for approx. 30 seconds
when the vehicle is unlocked.
The lights go out if the ignition is switched on or
when leaving the Welcome Home lighting
If the ignition key is withdrawn and the door is ope-
ned while the lights (not the parking light left/right)
are on, a gong warns of possible battery dis-
charge.
In some countries, differences are possible
due to provisions of law.

Automatic Headlight Beam
Adjustment Vehicles with Litronic headlights feature auto-
matic 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 headlight 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.
The level of the low beam rises perceptibly
when the high beam is switched on.
If these test items are not met, the headlight beam
adjustment must be checked by an authorized
Porsche dealer.
Turn Signal/ Headlight Dimmer/

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.

Automatic Speed Control The automatic speed control maintains any
selected speed between 15 mph and 145 mph/
30 km/h and 240 km/h without you having to use
the accelerator.
The automatic speed control is operated with the
lever on the steering wheel.
Warning!
Risk of accident and consequent personal in-
jury. A constant speed may not be safe in
heavy traffic, or on winding or slippery
roads.
With the speed control system engaged, the
engine speed will not return to idle when re-
moving the foot from the accelerator pedal.
fDo not use the speed control when it may be
unsafe to keep the car at a constant speed.
fObserve all local and national speed limits. Switch automatic speed control readiness
on fPress button A on the automatic speed control
lever.
Hold and store speed fBring the car to the desired speed with the
accelerator.
fThen briefly push the operating lever forward
(position 1).Accelerating (e.g. to overtake) Option 1
fIncrease the speed as usual with the
accelerator.
When you ease off the accelerator, the
previously saved value is set again.
Option 2
fPush operating lever forward (position 1) until
the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 3
fPush lever slightly forwards (position 1)
(a maximum of 10 times).
The speed is increased by 1 mph (1.6 km/h)
each time.
Note on operation
Speed control operation is automatically interrupt-
ed if the speed is increased by more than approx.
16 mph (25 km/h ) for longer than 20 seconds.
This green indicator light in the
speedometer now indicates readiness.

113
Decelerating Option 1
fPull operating lever towards the steering wheel
(position 2) until the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 2
fBriefly move lever towards the steering wheel
(position 2) (a maximum of 10 times).
The speed is reduced by 1 mph (1.6 km/h)
each time.
Interrupting automatic speed control
operation fPull operating lever downwards briefly
(position 3) or
fOperate brake or clutch pedal or
fSwitch Tiptronic transmission to selector lever
position N.
fPlease observe the chapter “TIPTRONIC S” on
Page 147.
The speed driven before the interruption remains
stored in the memory.
Automatic speed control operation is
interrupted automatically:
– If the set vehicle speed is exceeded by more
than approx. 16 mph (25 km/h) for longer than
20 seconds.
– If the actual vehicle speed falls to approx.
6 mph (10 km/h) below the set vehicle speed
for longer than 5 seconds (upward slopes).
– For PSM control operations.
Resuming the stored speed fBriefly push operating lever upwards
(position4).
The speed control accelerates/decelerates
the vehicle to the stored speed.
The stored speed should only be recalled when
traffic conditions and the road surface so permit.Switching automatic speed control
readiness off fPress button A on the automatic speed control
lever.
The green readiness light in the speedometer
goes off.
When the vehicle is parked and the ignition
switched off, the memory is cleared.
Important note
On upward or downward slopes, the set speed
cannot always be maintained by the automatic
speed control.
To obtain sufficient engine braking or a better en-
gine-speed range, therefore, you have to select a
lower gear.

Information on air-conditioning
compressor– May switch off briefly to ensure sufficient
engine cooling if the engine is operating under
extreme load.
– Operates most effectively with the windows
closed.
If the vehicle has been in the sun for a long
time, it is a good idea to ventilate the interior
briefly with the windows open.
– Depending on the outside temperature and
humidity, condensation can drip from the
evaporator and form a pool under the car.
This is normal and not a sign of leakage.
– If uncooled air flows out when the lowest
temperature has been set, switch off the air
conditioning compressor and have the fault
remedied.
Please contact your authorized Porsche dealer
for further information.
