226. FM reception A vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely nor-
mal for a given reception area, and they do not in-
dicate any problem with the radio itself.
Note
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and appro-
ved by Porsche may impair radio reception. Fading and drifting
FM range is limited to about 25 miles (40 km), ex-
cept for some high power stations.
If a vehicle is moving away from the desired stati-
on’s transmitter, the signal will tend to fade and/or
drift. This condition is more prevalent with FM than
AM, and is often accompanied 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 adjus-
ting the tone control for greater bass response un-
til the disturbance has passed. Multipath
Because of the reflecting characteristics of FM, di-
rect 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, someti-
mes 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.

Shifting Gear Shifting gear on the steering wheel
With the toggle switches on the steering wheel,
you can change temporarily from automatic
selection mode D to manual mode M.
Advantages:
– Shifting down before bends and on entering bu-
ilt-up areas.
– Shifting down on downward slopes (engine bra-
king).
– Shifting down for brief spurts of acceleration.
– Selecting 1st gear for moving off.
The manual selection mode remains engaged:
– for cornering (depending on the lateral
acceleration) and overrunning,
– when the vehicle is stationary
(e.g. at a junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds
(unless cornering or overrunning),
– if you depress the accelerator to kickdown,
– after moving off. Temporary change-down
Conditions:
Speed is higher than approx. 33 mph (54 km/h).
fDepress accelerator quickly.
The Tiptronic changes temporarily to the spor-
tiest gear-changing map, i.e. to the highest
possible gear-changing points. Correspondin-
gly, the transmission shifts down immediately
by one or two gears.
Ending the function:
fRelease the accelerator markedly (by approx.
25%). Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to ma-
nual mode M using the toggle switches on the
steering wheel.
fFor optimum acceleration, e.g. when overta-
king, depress the accelerator pedal beyond
the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
wide open throttle position.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel fu-
mes might be present. Be especially cautious
of such devices such as hot water heaters
which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all ti-
mes while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral or the se-
lector lever is in position P or N. fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), je-
welry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high vol-
tage is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Remove the ignition key. fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cove-
rage.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
