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.

Roof Transport System(Coupé only)
fPlease follow the separate instructions for fit-
ting the Roof Transport System.
fOnly use Roof Transport Systems from the
Porsche Tequipment product range or Roof
Transport Systems which have been tested
and approved for your car by Porsche.
Fitting normal commercially available luggage
racks is not possible.
The Porsche Roof Transport System allows you
to carry various sports and hobby equipment.
Your authorized Porsche dealer will be pleased to
tell you about the various different uses of the
Roof Transport System.
Safety notes!
fCompletely remove the Roof Transport System
before using an automatic car wash – risk of
damage to the vehicle!
fDo not exceed the maximum permitted pay-
load, the maximum permitted gross weight
and the maximum permitted axle loads.
Please observe the chapter “WEIGHTS COU-
PÉ” on Page 292.
fDistribute load evenly, with heavy items as low
as possible.
Items of luggage must not project beyond the
side of the load area.
fFix and secure every item to the basic carrier
with a rope or lashing strap (do not use elastic
rubber tensioners).
fBefore every journey, and at regular intervals
during long trips, check that Roof Transport
System and load are secure. Re-tighten if nec-
essary and secure additionally by locking.When the Roof Transport System is loaded, the
maximum speed depends on the nature, size and
weight of the load being carried.
Driving, braking and steering behavior change due
to the higher center of gravity and the greater
wind-resistant area. You should adapt your driving
style appropriately.
Since fuel consumption and noise are increased
with the Roof Transport System fitted, it should
not remain on the vehicle if not in use.

wash, residues may adhere to the windshield.
These residues can only be removed using a
special cleaning solution.
Please contact your authorized Porsche dealer
for further information.

Leather Characteristics and special features
The natural surface markings of leather, e.g.
creases, healed scars, insect sting marks, struc-
tural differences and slight variations in shade and
grain add to the attractiveness of the natural leath-
er product.
A special mention must be made here of natural
leather.
For natural leather, carefully selected hides of the
highest quality are used. It is not covered com-
pletely with dye on production.
“Nature’s signature” is therefore easily recogniza-
ble.
This fine material is distinguished by an outstand-
ing seating comfort, special suppleness and a typ-
ical patina. Leather care and treatment
fClean all types of leather regularly to remove
fine dust using a soft, damp, white woollen
cloth or a commercially available microfibre
cloth.
fRemove heavy contamination with Porsche
leather cleaner.
Please always follow the instructions for use
given on the containers.
Caustic cleaners and hard cleaning objects
must not be used.
Perforated leather must under no circum-
stances get wet on its reverse side.
Once cleaned, leather (particularly the heavily
stressed leather seats) must be treated only with
Porsche leather care liquid.
Fabric, upholstery, carpets and
floor-mats fUse only a vacuum cleaner or a medium stiff
brush.
fRemove stains and spots with Porsche stain
remover.
The Porsche range of accessories includes non-
skid floor-mats to protect the carpets in summer
and winter.
Warning!
Risk of an accident.
fAlways check the movement of the pedals be-
fore driving and make sure that they are not ob-
structed by a floor-mat or any other object.
fSecure the floor-mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle - do not install them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.

Practical Tips, Emergency Service
Wheel Bolts
Warning!
Risk of wheel bolt breakage and wheel sepa-
ration, resulting in severe personal injury or
death.
fFollow all instructions concerning wheel bolts. fAlways clean the wheel bolts before fitting.
fApply a thin coat of Optimoly TA (aluminium
paste) on the thread and between the bolt head
and movable spherical cap ring (arrows).
The bearing surface of the spherical cap
facing the wheel must not be greased.
fReplace damaged wheel bolts.
Only use the Original Porsche wheel bolts spe-
cially designed for this vehicle type.
Tightening torque Tightening torque of wheel bolts:
130 Nm/96 ftlb.
Wheel Securing Bolts The wrench socket for the wheel securing bolts is
in the tool pocket.
To loosen or tighten the wheel bolt with anti-theft
protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
Note on operation
On vehicles with 17 mm spacers on the rear axle,
the wheels are secured with wheel nuts.
On request, separate anti-theft protection for the
wheel nuts can be mounted.
Please consult an authorized Porsche dealer.
