2006 PORSCHE CAYMAN change wheel

Shifting Gear
169
M - Manual Selection Mode The currently selected gear is retained if you
change from D to M.
If you shift from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Warning!
The kickdown function is not active in manual
selection mode “M”.
fTherefore shift down manually when accelerat-ing (e.g. to overtake). Two toggle switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward gears.
Shifting up
fPress upper part (+) of a toggle switch.
Shifting down
fPress lower part (–) of a toggle 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 are not executed by the
controller.
You can shift down two gears at once by quickly
pressing the toggle switches twice.
If the engine-speed limit is reached, an auto matic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking. If manual mode fails, the control electronics
switch to automatic mode. In this event, the
instrument cluster will display selector lever posi-
tion D.
fTo remedy the fault, please consult an author-
ized Porsche dealer.
PSM switched off and/or Sport mode
switched on
fPlease observe the chapter “SWITCHING OFF
PSM” on Page 63.
fPlease observe the chapter “SPORT MODE” on
Page 61.
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
The restriction can be cancelled for one gear
change by depressing the accelerator to
kickdown. If, for example, the engine speed limit
is reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up by accelerating to kickdown.
fDepress the accelerator pedal beyond the
full-throttle point (kickdown).

Shifting Gear Manual mode failure
If manual mode fails, the control electronics
switch to automatic mode. In this event, the
instrument cluster will display selector lever
position D.
fHave the fault remedied.
Consult an authorized Porsche dealer.
Stopping fFor 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,
select position N (neutral).
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
position P.
Parking fGo easy on the accelerator.
fWhen parking or maneuvering in a small
space, control the speed by careful use of the
footbrake. Driving in winter In wintery 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, towing fPlease observe the chapter “TOWING” on Page
260.
Emergency program
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-
w a r d f a s t e n o u g h t o c a u s e r e a r w h e e l l o c k u p .
fDo not shift into R while the vehicle is moving forward.
A transmission fault is indicated by the following
symptoms:
–The 4th-gear display flashes.
– The warning “Tiptronic emergency run”
appears in the on-board computer.
– The transmission no longer shifts.
Regardless of selector lever position, 4th is
the only forward gear still available.
fAdapt your driving style to the changed han-
dling.
fTo remedy the fault, please consult an author-
ized Porsche dealer.

Maintenance, Car Care
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 to the correct pres-
sure.
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 (traffic lights, jams, level crossings). 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.
The EPA estimated m.p.g. is to be used for
comparison purposes, actual mileage may
be different from the estimated m.p.g., de-
pending on your driving speed, weather con-
ditions and trip length. Your actual highway
mileage will probably be less than the esti-
mated m.p.g.
fPlease observe all local and national speed lim-
its.

Practical Tips, Emergency Service
215
Tire replacements If in doubt, contact your Porsche dealer.
Use only tire makes and types approved by
Porsche.
If you do not use a Porsche recommended
replacement tire, make sure that you
purchase your new tires from a reputable tire
dealer and that the dealer complies with all
manufacturers warnings for those tires.
Only tires with the same make and with the
same specification code (e.g. “N0”, “N1”...)
can be mounted.
Before mounting new tires, check with your
Porsche dealer about the current release
status.
Use tires with “ZR” quality standards. There
are currently no standards concerning tire
strength at speeds above 150 mph (240 km/h).
Tires should be replaced no less than on one axle
at the time.
Only tires of the same make and type must be
used. Mixed tires are not permissible.
Initially, new tires do not have their full traction.
You should therefore drive at moderate speeds
during the first 60 - 120 miles (100 - 200 km). If new tires are installed only on one axle, a notice-
able change in handling occurs due to the different
tread depth of the other tires.
This happens especially if only rear tires are re-
placed. However, this condition disappears as the
new tires are broken in.
fPlease adjust your driving style accordingly.
Installation of new tires should only be done by a
qualified tire technician.
Valves
Rubber valve stems must be replaced every time
a tire is replaced.
For metal valves, the installation and replacement
instructions must be observed.
fUse only genuine Porsche metal valves.
fProtect the valve inserts against soiling with
valve caps.
Soiled valve inserts can cause a gradual loss
of air.
fUse only plastic valve caps.
Parking at the curb
Warning!
Hard impacts against curbs (or traffic
islands) are dangerous and may cause hid-
den tire damage which is not noticeable until
later. Such damage can result in accidents at
high speeds causing severe personal injury.
Depending on the force of impact, the edge
of the rim can also be damaged.
fIf you are in doubt, have the wheel checked by
an expert, particularly if you suspect damage
on the inside.
fIf you must drive over a curb or other obstacle,
drive slowly and at an obtuse angle. Exercise care when parking along curbs.

Practical Tips, Emergency Service
Changing a wheel
Warning!
Risk of injury. The car may slip off the jack.
fMake sure that no one is in the vehicle when
jacking up and changing a wheel.
fAlways place the car on stable supports if work
has to be carried out under the car.
Risk of damage to the brake discs of the
Porsche Ceramic Composite Brake (PCCB).
fAlways screw in both assembly aids when changing a wheel.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not sup-
plied with the car. They are available at your
authorized Porsche dealer.
1. Fully apply the handbrake, engage 1st gear or
select position P and withdraw the ignition key.
2. Secure the car against rolling away, e.g. by
means of wedges under the wheels on the op-
posite side.
This is particularly important on slopes.
Screw in assembly aid for vehicles without
Porsche Ceramic Composite Brake3. Slightly slacken the wheel bolts of the wheel to
be changed.
4. Raise the car until the wheel lifts off the
ground.
Please observe the chapter “LIFTING THE VE-
HICLE WITH A LIFTING PLATFORM OR GARAGE
LIFT” on Page 223.
Screw in two assembly aids for vehicles with
Porsche Ceramic Composite BrakeNote on operation
fTo remove or mount the spacers:
Please observe the chapter “SPACERS” on
Page 230.
5. Remove 1 or 2 wheel bolts (see respective
illustration). Screw in assembly aids instead of
the wheel bolts.
Remove the remaining wheel bolts.
