Shifting Gears
Manual Transmission, ClutchThe positions of the gears are shown on the shift
diagram on the gearshift lever.
Warning!
Risk of accident.
fDo not obstruct the pedal travel with floor mats
or other objects.
Nonskid floor mats of the correct size are
available at your authorized Porsche dealer.To avoid damage to the clutch and transmis-
sion:
fAlways depress the clutch pedal fully when
changing gears. Make sure that the gearshift
lever is completely engaged.
fOnly shift into reverse when the car has come
to a complete stop.
fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the backup lights are illuminated.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the ta-
chometer, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permit-ted engine speed when shifting down.

Tiptronic SThe Porsche Tiptronic is a five-speed transmission
with an “automatic” and a “manual” selection
mode.
In automatic selection mode (selector lever po-
sition D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the rocker switches on the
steering wheel.
In manual selection mode (selector lever posi-
tion M), you change gear using the rocker switch-
es on the steering wheel.
You can change between selector lever position D
and M as you wish while driving.
Note
Take care not to operate the rocker switches on
the steering wheel inadvertently in either auto mat-
ic or manual mode, thereby triggering undesired
gear changes.Keylock positionThe ignition key can be withdrawn only in selec-
tor lever position P.
Changing the selector lever positionThe selector lever is locked with the ignition key
withdrawn.
The selector lever can be moved from position P
or N only with:
– The ignition switched on
– The brake pedal pressed and
– The release button pressedRelease button
The release button (arrow) in the selector lever
prevents unintentional gear changes.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can be started only if the brake pedal
is depressed and the selector lever is in position
P or N.Moving offfOnly select the desired position for moving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
fSince the vehicle creeps when in gear, do not
release the brake until you want to move off.
fAfter selecting a gear, do not accelerate until
you can feel that the gear is engaged.

Selector Lever PositionsP – Parking lockfEngage parking lock only when vehicle is sta-
tionary.
fEngage parking lock after applying the hand-
brake and release it before releasing the hand-
brake.
The ignition key can be withdrawn only in selec-
tor lever position P.R – Reverse gearfSelect only if car is stationary and the brake is
applied.N – NeutralSelector lever position N must be selected for
towing or in car washes, for example.
fOnly select the desired position for moving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
D - Automatic selection modeSelect position D for “normal” driving. The gears
are shifted automatically according to the acceler-
ator position and speed.
Depending on the way the vehicle is driven and on
the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator ped-
al.
Depending on lateral acceleration, upward chang-
es on bends are not made until the engine-speed
limit is reached.
Under braking, and depending on the amount of
deceleration, the Tiptronic changes down earlier.
For subsequent cornering, the right gear is en-
gaged when pressure is applied to the brakes be-
fore the bend. The bend is taken in the right gear,
and when you accelerate out of the bend you do
not have to shift down.Sport mode switched on
fPlease observe the chapter “SPORT MODE” on
Page 64.
If the Sport mode program is switched on, Tiptron-
ic switches to a sporty gear-changing map and
shortens the shifting periods.
Deceleration downshifts are commenced earlier.
Downshifts are already carried out in the case of
slight decelerations, even at higher engine
speeds.
Driving off
In 2nd gear, the vehicle moves off with the throt-
tle only slightly open.
Move off in 1st gear with the throttle open wider
or when the engine is cold.

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.
