2006 PORSCHE 911 CARRERA wheel

Shifting Gears
169
Two rocker switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward speeds.
Shifting up
fPress upper part (+) of a rocker switch.
Shifting down
fPress lower part (–) of a rocker switch.
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine-speed limit will not be executed by
the controller.
You can change down two gears by quickly press-
ing the rocker switches twice.
If the engine-speed limit is reached, an automatic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
Select an appropriately low gear on upward and
downward slopes.
This will ensure optimum use of engine power and
engine braking.PSM switched off and/or Sport mode
switched on
fPlease observe the chapter “PORSCHE STABI-
LITY MANAGEMENT (PSM)” on Page 72.
fPlease observe the chapter “SPORT MODE” on
Page 71.
If the PSM is switched off and/or Sport mode is
switched on, an automatic upshift does not occur
when the engine speed limit is reached.
Cancelling upshift suppression
This restriction can be cancelled for one gear
change by depressing the accelerator to kick-
down. If, for example, the engine speed limit is
reached during overtaking and the automatic up-
shift does not occur, the transmission in this case
shifts up by accelerating to kickdown.
fDepress the accelerator pedal beyond the full-
throttle point (kickdown).Manual mode failure
If manual mode fails, the control electronics
switch to automatic mode. In this event, the instru-
ment cluster will display selector lever position D.
fHave the fault remedied at an authorized
Porsche dealer.

Shifting Gears
StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
fFor a longer stop with the engine running, se-
lect position N (neutral) and hold vehicle in po-
sition with the foot brake.
Select lever position D only when the foot
brake pedal is depressed.
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to po-
sition P.
ParkingfGo easy on the accelerator!
fWhen parking or maneuvering in a small
space, control the speed by careful use of the
footbrake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode. This prevents the
occurrence of gear changes that could cause
wheelspin.Tow-starting, towingfPlease observe the chapter “TOWING” on
Page 281.Reduced driving programA transmission fault is indicated by the following
symptoms:
–The 4th gear display on the instrument clus-
ter flashes.
– The warning “Tiptronic emergency run” ap-
pears on the on-board computer.
– The transmission no longer shifts.
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program.
Damage to the vehicle may result as well as
loss of control, if the vehicle is moving for-
ward fast enough to cause rear wheel lockup.
fDo not shift into R while the vehicle is moving forward.
Proceed as follows in the event of a transmission
fault:
1. Stop in a safe place.
2. Move selector lever to position P, switch the ig-
nition off and wait for 10 seconds.
3. Start the engine.
2nd gear in selector position D and reverse
gear R are now available.
4. Have the fault seen to immediately at an au-
thorized Porsche dealer.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause 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 also 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
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers 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
times 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 position
or the selector lever in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, 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 engine-compartment blower is mounted
on the engine-compartment lid.
The engine-compartment blower 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, the ignition switched off, and exercise
extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme 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.
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
cannot 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
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
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.
Power measurements Power measurements on dynamometers are not
approved by Porsche.

Fuel Economy Fuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications.
Air cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated at correct pressure.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
fSwitch off the engine if stationary for longer
periods. fAny additional weight carried in the vehicle re-
duces fuel economy. Always keep cargo to a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to in-
creased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
fDo not drive with the Roof Transport System
mounted unless you need it.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may
be different from the estimated m.p.g.,
depending on your driving speed, weather
conditions and trip length. Your actual
highway mileage will probably be less than
the estimated m.p.g.
fPlease observe all local and national speed
limits.
Operating Your Porsche in other
Countries Government regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards. There-
fore, cars built for the U.S. and Canada differ from
vehicles sold in other countries.
If you plan to take your Porsche outside the conti-
nental limits of the United States or Canada, there
is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessive engine knock and se-
rious damage to both engine and catalytic con-
verters could result;
– service may be inadequate due to lack of prop-
er service facilities, tools or diagnostic equip-
ment;
– replacement parts may not be available or very
difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about ship-
ping and forwarding requirements, as well as cur-
rent import and customs regulations.

Maintenance, Car Care
Car Care Instructions fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 198.
Regular and correct care helps to maintain
the value of your car and is also a
precondition for the New Vehicle Warranty
and the Anti Corrosion Warranty.
Your authorized Porsche dealer has specially
developed car-care products from the
Porsche program available either singly or
as complete car-care sets. They will be
pleased to help you select suitable products.
Whether you use Porsche products or other
commercially available cleaning agents first
make sure of their correct application.
A Porsche that is well-cared for can look like new
for years. It all depends on the amount of care the
owner is willing to give the car.
Warning!
Risk of serious personal injury or damage to
the vehicle or property.
Cleaning agents may be hazardous to your
health.
Most chemical cleaners are concentrates
which require dilution. High concentrations
might cause problems ranging from irritation
to serious injury as well as damage to your
vehicle.
fKeep cleaning agents out of reach from chil-
dren.
fObserve all caution labels.
fAlways read directions on the container before
using any product. These directions may con-
tain information necessary to avoid personal
injury.
fDo not use fuel, kerosene, naphtha, nail polish
remover or other volatile cleaning fluids. They
may be toxic, flammable or hazardous in other
ways. Only use spot removing fluids in a well
vented area.
fDo not clean the underside of chassis, fend-
ers, wheel covers, etc., without protecting
your hands and arms as you may cut yourself on sharp-edged metal parts. Moisture and road salt on brakes may affect brak-
ing efficiency.
fTest the brakes after each vehicle washing.

Maintenance, Car Care

Automatic car washes
Optional add-on parts or parts which project
beyond the contours of the vehicle may be
damaged by design features (e.g. brushes) of au-
tomatic car washes.
The following parts are particularly
susceptible to damage:
– Convertible top (hot wax treatment cannot be
used, as the wax attacks the convertible top
material)
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– Roof Transport System (always remove com-
pletely)
–Rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from get-
ting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using auto-
matic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills. Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
Door lock fTo prevent the door lock from freezing during
the cold season, the lock cylinder should be
covered during a wash.
fShould the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.

Maintenance, Car Care
Light alloy wheels fPlease observe the chapter “WASHING” on
Page 219.
Warning!
Danger of accident if cleaning agents (e.g.
wheel cleaning agents) come into contact
with the brake discs. The resulting film on the
brake discs can impair braking perform-
ance.
fMake sure that no cleaning agent comes into
contact with the brake discs.
fIf cleaning agent has come into contact with
the brake discs, thoroughly clean the brake
discs with a strong jet of water.
fPaying attention to any road users behind you,
dry the brake discs by applying the brakes at short intervals.Pitting may occur if metallic particles which cause
contact corrosion (e.g. brass or copper in brake
dust) are allowed to remain on the aluminum for
too long.
fIf possible, wash the wheels with a sponge or
wash brush about every two weeks. In areas
where salt is spread on winter roads or there is
a lot of airborne industrial dust, it is best to
clean the wheels weekly.
The Porsche Light Alloy Wheel Cleaner
(ph-value 9.5) can be used for this pur-
pose.
If the ph-value of the detergent is incor-
rect, the protective coating on the wheels
will be destroyed.
Polishes which dissolve oxides, such as those
frequently used for other metals, or abrasive
tools or agents are unsuitable because they
break down the oxide film of the protective
coating and will cause discoloration of the
wheel.
fEvery three months, after cleaning, coat the
wheels with a car wax or non-corrosive grease
(vaseline).
Using a clean cloth thoroughly rub the grease
into the surface.
Door, roof, lid and window seals fWash dirt (e.g. abrasion, dust, road salts) from
all seals regularly using warm soapy water. Do
not use any chemical cleaning agents or sol-
vents.
When there is a frost hazard, the outer door seals
and the front and rear lid seals can be protected
against freezing into place by a suitable care prod-
uct.
In order to prevent damage to the anti-
friction coating, the inner door seals, the
convertible top seals and hardtop seals must
not be treated with care products. Headlights, lights, interior and exterior
plastic parts fUse only clean water and a little dishwashing
detergent to clean light lenses, plastic head-
light lenses, plastic parts and surfaces.
Do not clean when dry.
Use a soft sponge or a soft, lint-free cloth. Gen-
tly wipe the surface without applying too much
pressure.
The Porsche inside window cleaner is also suit-
able for cleaning plastic surfaces. Follow the
cleaning instructions on the container.
Never use other chemical cleaners or
solvents.
fRinse cleaned surfaces with clear water.
