Instrument Panel and Multi-Function Display
Selecting settings in the Tire pressure menu
(type and size of fitted tire)
Warning!
Risk of accident due to excessive speed. This
could lead to serious personal injury or
death.
f Always observe the permissible maximum
speed of the respective tire.
f Exceeding maximum tire speed could result in
a tire burst, causing loss of control of the
vehicle. This could lead to serious personal
injury or death.
Moreover, Porsche recommends obeying all
traffic laws at all times to maintain the safety of yourself and all vehicle occupants. Warning!
Incomplete entries or selection of the wrong
tires on the multi-function display affect
correct indication of warnings and
messages.
f The settings must be updated in the “Tire
pressure ” menu after changing a wheel, filling
with tire sealant or adding air (after previous
warning “ Tire pressure!”).
f Please see the chapter “RED WARNING – TIRE PRESSURE!” on page 133. The new tire type and tire
size must be selected
even if the settings for the new set of wheels are
the same as for the old wheels.
Available setting options:
–“ 18 inch ”
–“ 19 inch ”
–“ 20 inch ”
Tire selection has only been successfully
completed when the following message appears
on the multi-function display (example).
“Summer tires 19-inch was set. No monitoring,
system is learning”.
f Please see the chapter “SYSTEM LEARNING”
on page 134. Notes
The message “Action cancelled” appears if the
setting process is interrupted. All entries made up
to this point are lost, and the original settings
remain in effect.
Before fitting tires with dimensions that are not
already stored in the mult
i-function display, the
missing information should be added to the
multi-function display.
f Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
f Use only tires approved by Porsche.
The available items in the tire pressure menu
depend on the model type. For this reason it is
possible that some of the selection options shown
here are not available on your multi-function
display.
1. Select
> “Tire pressure ”
2. “Adjust ”
and confirm.
3. Select “ Summer tires ” or
“ Winter tires ” or
“ All-season ”
and confirm.
4. Select the tire size
and confirm.

Minor Repairs
f
Valve caps protect the valve from dust and dirt,
and thus from leakage. Always screw caps
tightly down. Replace missing caps
immediately.
f Use only plastic valve caps.
f For safety reasons, don't use tire inflating
bottles.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on page 326.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle
placard or tire inflation pr essure label, you should
determine the proper tire inflation pressure for
those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring (TPM)
that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as po ssible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and
can lead to tire failur e. Under-inflation also
reduces fuel efficiency an d tire tread life, and may
affect the vehicle’s handling and stopping ability. Please note that the TPM is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPM low tire pressure
tell-tale.
For further information on the tire pressure
monitoring:
f
Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
When tires are warm, the tire pressure is
increased.
f Never let air out of hot tires. This could cause
the tire pressure to fall below the prescribed
value.
Insufficient tire pressure can cause tires to over-
heat and thus be damaged – even invisibly. Hidden
tire damage is not eliminated by subsequently
correcting the tire pressure. Overloading
Danger!
Risk of damage to vehicle parts, loss of
control and serious pers onal injury or death.
f Do not overload your vehicle. Be careful about
the roof load.
f If you plan to load the vehicle, first correct the
tire pressure. Tire pressure for loaded vehicle
can be found on the tire pressure plate and in
the chapter technical data.
f Never exceed the specified axle load.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous
vehicle reactions and long braking distances.
Damage due to overloading is not covered by
the vehicle warranty.
Tire damage may also be caused by
overloading, and this damage is not covered by your tire warranty.
f Please see the chapter “LOADING INFORMA-
TION” on page 236.

Example of a tire pressure plateTire Pressure plateInformation on the tire pressure plate
A Seating capacityMaximum number of vehicle occupants,
including the driver.
B Vehicle load limit Is the maximum total weight limit specified of
the load (passengers and cargo) for the
vehicle. This is the maximum weight of
passengers and cargo that can be loaded into
the vehicle.
Please see the chapter “LOADING
INFORMATION” on page 236. C Original tire size
Size of tires mounted at the factory.
D Recommended cold tire inflation pressure These values are for cold tires (68 °F/20 °C).
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may bu ild up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause
partial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surfaces to prevent this.
Tire lifeTire life depends on various factors, i.e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
f Inspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the tires.
We recommend, however, that you do not let the
tires wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake
components.
f Use only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
f Please see the chapter “WHEELS, TIRES” on
page 325.
f Follow instructions issued by the supplier of the chains.
Fit snow chains only on the rear axle.
f Remove spacers if snow chains are mounted.
f Before fitting chains, remove accumulated ice
and snow from the wheel well.
f Vehicles with snow chains must not be driven
faster than 30 mph (50 km/h) .
Different states and countr ies have varying statu-
tory requirements regarding maximum speed.
f Check with local authorities for possible
restrictions.
f Remove chains as soon as the roads are free
of ice and snow.

the tire sidewall.
f Please note that in addition to snow tires,
all-season tires are also subject to speed limits
and bear this identification.

Wheels, TiresfApproval of tire and wheel sizes is grante d based on extensive testing. Your authorize d Porsche dealer will be pleased to advise you about the current
approval status.
By fitting tires that have been approved by Porsche, you can be sure that you have the best possible tires for your Porsche.
The load capacity coefficient (e.g. “105 ”) and code letter (e.g. “V”) for permitted top speed are minimum requirements.
When fitting new tires or changing tires: Please see the chapter “TIRES AND WHEELS” on page 280.
f Snow chain clearance can only be guaranteed for the tires marked
1). Snow chains can only be fitted on the rear wheels. Maximum speed
30 mph (50 km/h). Only use fine-link cross-ty pe or edge chains approved by Porsche.
