Operation, Safety
81
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
Push the lever to the upper or lower pressure
point – turn signals flash three times
3 – High beam
4 – Headlight flasher
Lever in center position – Low beam
When high beam and head light flasher are select-
ed, the blue indicator light in the tachometer is lit. The turn signal lever turns off automatically when
the steering wheel is st
raightened out after com-
pleting a turn.
Lane changer f To 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.
f If the frequency of the display becomes notice-
ably faster, check the operation of the turn sig-
nal bulbs. Headlight flasher (With ignition on or off)
fTo flash the headlights to oncomming motor-
ists, 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.
fMove the lever up or down to switch on the
right or left parking light.
Individual Light FunctionsFurther individual light functions are available in
vehicles with Sport Chrono Plus package.
f Please refer to the chapter ”Individual Memory“
in the separate PCM operating instructions.

Operation, Safety
Fading and drifting
FM range is limited to
about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving aw ay from the desired sta-
tion’s transmitter, the signal will tend to fade and/
or drift. This condition is more prevalent with FM
than AM, and is often ac companied by distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjust-
ing the tone control for greater bass response un-
til the disturbance has passed.
Multipath
Because of the reflecting characteristics of FM,
direct and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception. Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.
Compact disc player
Caution!
To avoid damage to compact disc player and
discs.
f Use only compact discs labeled as shown, hav-
ing no dirt, damage or warpage.
f Never attempt to disassemble or oil any part
of the player unit.
Do not insert any object other than a disc into
the slot.
Remember there are no user-serviceable parts
inside the compact disc player.
f Do not allow the disc to sustain any finger-
prints, scrapes or stickers on the surfaces.
This may cause poor sound quality.
Hold the disc only on the edge or center hole. f
When not in use, take th e disc out of the player,
put the disc back into its case and store it
away from dust, heat, damp and direct
sunlight.
Leaving the disc on the dashboard in the sun
can damage the disc.
f If the disc gets dirty, clean the disc by wiping
the surfaces from the center to the outside in
a radial direction with a soft cloth.
Do not use a conventional record cleaner or
anti-static record preservative.
Disc cleaners are available in audio stores.

Tachometer The tachometer shows the engine speed in revolu-
tions per minute (rpm).
The beginning of the red marks at the right end of
the scale indicates the maximum permissible en-
gine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be select-
ed.
Shift to the next lower gear when the engine rpm
drops below 1,500 rpm.
Caution!
To avoid severe engine damage.
f Always observe the engine rpm before down-
shifting to a lower gear, so you do not exceed the maximum engine rpm.
Flashes in synchronism with the turn signals.
Left arrow – left turn signals
Right arrow – right turn signals
f If the frequency of the display becomes notice-
ably faster, check the operation of the turn sig-
nals.
Lights when high beam or headlight flasher is
switched on.
The indicator light goes out when the high beams
are switched off.
The indicator light flashes in the event of cornering
light failure.
Gear Shift Indicator(in vehicles with manual transmission)The consumption-orientated gear shift indicator A
on the display panel of the on-board computer
assists a fuel-saving driving style. The gear shift
indicator lights up as a recommendation to shift
up to the next-higher gear depending on the
selected gear, engine rpm and accelerator pedal
position.
f When the gear shift indicator A lights up,
change to the next higher gear to decrease
fuel consumption.

How Emission Control Works When an automobile engine is running, it uses en-
ergy generated through the combustion of a mix-
ture of air and fuel. Depending on whether a car is
driven fast or slowly or whether the engine is cold
or hot, some of the fuel (hydrocarbons) may not
be burned completely, but may be discharged into
the engine crankcase or exhaust system. Additon-
al hydrocarbons may enter the atmosphere
through evaporation of fuel from the fuel tank.
These hydrocarbons (HC), when released into the
air, contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion proc-
ess and discharged into the exhaust system.
To reduce these pollutants, your Porsche is
equipped with a precisely calibrated fuel injection
system to assure a finely balanced air/fuel mixture
under all operating conditions.
Oxygen sensor The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the
exhaust and signals the information to an electron-
ic control unit. The control unit corrects the air/
fuel ratio, so the engine always receives an accu-
rately metered air/fuel mixture. Crankcase ventilation Through crankcase ventilation, undesirable emis-
sions from the engine crankcase are not permit-
ted to reach the outside atmosphere. These emis-
sions are recirculated from the crankcase to the
air intake system. From here the emissions mix
with the intake air and are later burned in the en-
gine. Catalytic converters The catalytic converters are efficient “clean-up”
devices built into the exhaust system of the vehi-
cle. The catalytic converte rs burn the undesirable
pollutants in the exhaust gas before it is released
into the atmosphere.
The exclusive use of unleaded fuel is critical-
ly important for the life of the catalytic con-
verters. Therefore, only unleaded fuel must
be used. The catalytic converters will be damaged by:
– push or tow starting the vehicle
– misfiring of the engine
– turning off the ignition while the vehicle is mov-
ing or
– driving until the fuel ta nk is completely empty
– by other unusual operating conditions.
f Do not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law pro-
hibits use of leaded fuel in this car.
