“Comfort pressure Reduce speed“ warning
If the maximum speed of the preset comfort pressure is exceeded and the tire pressure is below a critical limit, a warning message appears on the multi-function display.
Driving at excessive speeds when the comfort pressure is active will destroy the tires.fReduce speed to below the displayed maximum speed.fAlways inflate the tires to the standard tire pressure when driving at higher speeds.
System learning
Tire Pressure Monitoring System begins to “learn” the tires after a wheel change, wheel transmitter replacement or update of the tire settings. During this process, TPMS recognizes the wheels and their locations.The message “ No tire pressure monitoring System is learning ” appears on the multi- function display.
The wheel learning process takes place exclusively when the vehicle is being driven (vehicle speed above 16 mph (25 km/h)).
TPMS requires a certain amount of time to learn the wheels. During this time, the current tire pressures are not available on the multi-function display:– The tire pressure warning light stays on until all wheels have been learned.– Lines (-.-) appear on the display of the “ TPMS” function.– The required pressures for cold tires (68 °F/20 °C) are shown under “ Fill info” in the “ TPMS” main menu.
Position and pressure information is displayed as soon as TPMS has assigned the wheels recognized as belonging to the vehicle to the correct wheel positions.fCheck the tire pressure for all wheels under “ Fill info”.fCorrect the tire pressure to the required pressure if necessary (differential pressure value “0.0”).
Tire pressure warnings
The tire pressure warning light on the instrument panel and a corresponding message on the multi-function display warn about loss of pressure in two stages (yellow and red), depending on the amount of pressure loss.

Warning light
The warning light in the instrument panel lights up: – When a loss in pressure has been detected (warning light: lights up continuously).– In the event of a defect in TPMS or a temporary fault (warning light: flashes for 60 seconds, then lights up continuously).– When learning new fitted wheels/wheel transmitters, as long as the vehicle’s own wheels have not yet been recognized (warning light: flashes for 60 seconds, then lights up continuously).
A warning message also appears on the multi- function display in the instrument panel.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
The tire pressure warning light on the instrument panel goes out only when the cause of the fault has been rectified.
Changing a wheel and replacing tires
fNew wheels must be fitted with radio transmitters for Tire Pressure Monitoring System. Before tires are changed, the battery charge condition of the wheel transmitters should be checked.fPlease contact an authorized Porsche dealer.fSwitch off the ignition when changing a wheel.
The tire settings on the multi-function display must be updated after changing a wheel.If the tire settings are not updated, the message “Tire change? Update settings” is displayed on the multi-function display.fUpdate the multi-function display settings the next time the vehicle is stationary.
Pressure increase as the result of temperature increase
In accordance with physical principles, the tire pressure changes as the temperature changes.For every 18 °F (10 °C) change in temperature, the tire pressure increases or decreases by around 1.5 psi/0.1 bar/10 kPa.
Partial monitoring
Monitoring of the other wheels is continued if there is a fault in one or two wheel transmitters.– The tire pressure warning light lights up.– The message “Restricted monitoring” appears on the multi-function display.– No tire pressures are displayed on the multi-function display for wheels with faulty wheel transmitters.
No monitoring
In the event of faults, Tire Pressure Monitoring System cannot monitor the tire pressure. The warning light on the instrument panel lights up and a corresponding message appears on the multi-function display.
Monitoring is not active: – In the event of a defect in TPMS or if more than 2 wheel transmitters are defective.– If wheel transmitters for Tire Pressure Monitoring System are missing.– During the learning phase after the tire settings have been updated.– After a wheel change without updating the tire settings.– If more than four wheel transmitters are recognized.– If there is external interference by other radio sources, e.g. wireless headphones.– If tire temperatures are too high.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.

The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.fDo not exceed the permitted maximum speed for the tires fitted to the vehicle.fEnsure that the tires are set to the correct inflation pressure.fObserve the maximum load for the vehicle.
Tire pressures
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires and causes damage. fAlways use an accurate tire pressure gauge when checking inflation pressures.fDo not exceed the maximum tire pressure listed on the tire sidewall. (Also refer to “Technical data”).fPlease see the chapter “TIRE PRESSURE PLATE” on page 247.fCold tire inflation pressure means: all tires must be cold, ambient temperature maximum 68 °F (20 °C), when adjusting the inflation pressure. Avoid sunlight striking the tires before measuring cold pressures, since the pressures would rise from temperature influence.fValve caps protect the valve from dust and dirt, and thus from leakage. Always screw caps tightly down. Replace missing caps immediately.
fUse only plastic valve caps.fFor safety reasons, don't use tire inflating bottles.
fPlease see the chapter “TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)” on page 287.
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 inflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pressure 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 System (TPMS) 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 possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS 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 TPMS low tire pressure tell-tale.
For further information on the tire pressure monitoring:fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
When tires are warm, the tire pressure is increased.fNever 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
Overloading can lead to dangerous vehicle reactions and long braking distances.fDo not overload your vehicle. Be careful about the roof load. fIf 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.fNever exceed the specified axle load.

Wheel alignment, wheel balancing
As a precaution, have wheels with summer tires balanced in the spring, and those with mud and snow tires before winter. Unbalanced wheels may affect car handling and tire life.Only the specified weights may be used for wheel balancing.
Self-adhesive weights must not come into contact with cleaning agents, since they could drop off.Uneven tread wear indicates wheel imbalance. In this event, the vehicle should be checked at an authorized Porsche dealer.
If, during a trip, uneven running or vibrations occur that could be caused by damage to tires or the car, the speed must be reduced immediately, but without braking sharply. If you continue your trip without having the cause of the fault remedied, you might lose control of your vehicle.fStop the vehicle and check the tires.fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer.
The summer tires of your Sports Car have been specially developed and adapted for high performance. At low outside temperatures (<15°C (60°F)), the tire characteristics change. This can result in noises occurring when parking or maneuvering at low outside temperatures.
Wheels with Tire Pressure Monitoring System (TPMS) sensors
Before changing wheels, make sure that the wheels are compatible with your vehicle’s TPMS.fCheck this with your authorized Porsche dealer.
Removing and storing tires
fAfter changing, adjust tire pressure and torque wheel bolts diagonally. Please see the chapter “CHANGING WHEELS” on page 254.fStore tires in a cool and dry place. Rotate periodically to avoid flat spots.fDo not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).fAvoid contact with fuel, oil and grease.
Tires must always remain on the same side of the vehicle.When wheels are removed, the direction of rotation and position of each wheel should be marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with their marking.
The perception that tire durability and performance are not affected by storage and age is unfounded. Chemical additives, which make the rubber elastic, lose their effectiveness over the course of time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from time to time.
Information
Under no circumstances should tires older than 6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT” code number. If, for example, the last four numbers read 1213, then the tire was produced in the 12th week of 2013.
Snow tires
The installation of Porsche approved snow tires is recommended.
Use Porsche approved snow tires for grip on snow and ice. Summer performance tires are not suitable for usage in cold, snowy, or icy conditions.Check with your local Motor Vehicle Bureau for possible restrictions.

15. Tighten wheel bolts in diagonally opposite sequence.Immediately after changing a wheel, use a torque wrench to check the prescribed tightening torque of the wheel bolts (160 Nm/118 ftlb.).
Note on operation for vehicles with Tire Pressure Monitoring
fOn vehicles with Tire Pressure Monitoring, the settings on the multi-function display must be updated after the wheel change.fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
Checking tire pressure with a pressure gauge
1. Remove the valve stem cap from the tire. 2. Press the pressure gauge onto the valve stem.
Information
fDo not press too hard or force the valve stem sideways, or air will escape.If the sound of air escaping from the tire is heard, reposition the pressure gauge.
3. Read the tire pressure on the gauge stem and compare it to the permissible tire pressure.This information can be found on the tire pressure plate or in the chapter Technical Data.4. Remove the pressure gauge. 5. Please see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.
