The warning light in the speedometer lights up:
– When a loss in pressure has been detected
– If the tire pressure monitoring is faulty
– When learning newly mounted wheels/wheel
sensors, as long as the vehicle’s own wheels
have not yet been recognized.
The tire pressure warning light in the instrument
panel goes out only when the cause of the fault
has been rectified.
No monitoringIn the event of faults the tire pressure monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel lights up
and a corresponding message appears on the
on-board computer.
Monitoring is not active when:
– the tire pressure monitoring is faulty,
– wheel transmitters for the tire pressure
monitoring are missing,
– temporarily after changing a wheel (learning
phase),
– more than four wheel transmitters are
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.
fPlease observe the chapter “WARNINGS ON
THE INSTRUMENT PANEL AND THE ON-
BOARD COMPUTER” on Page 116.

General information regarding the
on-board computer functionsRange on remaining fuel
The range on remaining fuel is continuously recal-
culated during the journey based on the fuel level,
current consumption and average consumption.
The more the fuel level falls, the more spontan-
eously the display reacts. For this reason, the
range on remaining fuel is not displayed if less
than 9 miles (15 kilometers).
If the vehicle's inclination changes while driving or
refuelling, incorrect range information may tempo-
rarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on re-
maining fuel is impossible.Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to “zero”.
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car battery will cause these
memories to be erased.
Tire pressure
The Tire pressure function of the on-board com-
puter displays the tire pressures dependent on
temperature in the four wheels. You can watch the
tire pressure rise and fall while driving.
The display is only for information. To correct the
tire pressures, always use the displayed values
from the “Info pressure” display in the Tire pres-
sure menu.

Warnings on the instrument panel and the on-board computerIf a warning message appears, always refer to the corresponding chapters in the Owner’s Manual.
Warning messages are issued only if all measurement preconditions are met. Therefore, check all fluid levels regularly –
in particular, always check the engine oil level after refuelling.

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/
Parking light / Flasher Lever Turn signals, low beam and high beam are ready
for operation when the ignition is on.
1– Turn signal left
2– Turn signal right
3–High beam
4– Headlight flasher

When high beam and headlight flasher are selec-
ted, the blue indicator light in the tachometer is lit.
The turn signal lever turns off automatically when
the steering wheel is straightened out after com-
pleting a turn.
Lane changer fTo indicate your intention when changing lanes
on the freeway, slightly lift or depress the lever
to the resistance point.
The lever will return to the OFF position when
released.
fIf the frequency of the display becomes notice-
able faster, check the operation of the turn si-
gnal bulbs. Headlight flasher (With ignition on or off)
fTo flash the headlights to oncomming moto-
rists, slightly pull the lever toward the steering
wheel and then release it.
The blue indicator light in the tachometer will
go on/off as you pull/release the lever. Parking lightThe parking light can only be switched on when
the ignition is switched off.

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.

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 163.
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.
