This device complies with Part 15 of the FCC Rules and RSS-210 of Industry Canada.
Operation of this device is subject to the following two conditions:1. This device may not cause harmful interference, and2. this device must accept any interference received including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
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.)
For information on the tire inflation pressure label:fPlease see the chapter “TIRES AND WHEELS” on page 244.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale (warning light) 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.
The display as well as the settings for the Tire Pressure Monitoring System take place on the multi-function display.
However, the tire pressure must still be set manually on the wheel.fPlease see the chapter “TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)” on page 287.
Driving the vehicle with low tire pressure increases the risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires.Please note that the Tire Pressure Monitoring System 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 Tire Pressure Monitoring System low tire pressure telltale. Low tire pressure reduces the road safety of the vehicle and destroys the tire and wheel.
Tire Pressure Monitoring System gives a warning about a pressure drop caused by natural diffusion as well as about a gradual loss of pressure caused by foreign objects.Tire Pressure Monitoring cannot warn you about tire damage that occurs suddenly (e.g. flat tire due to abrupt external effects).fWhen a red tire pressure warning appears, stop immediately in a suitable place and check the tires for damage. If necessary, remedy the damage with a tire sealant.fDo not by any means continue to drive with defective tires.
fSealing the tire with tire sealant is only an emergency repair so you can drive to the nearest specialist workshop.The maximum permitted speed is 50 mph (80 km/h) .fDo not drive with tires in which the tire pressure drops again very quickly. In case of doubt, have tires checked by a specialist workshop.fDefective tires must be replaced immediately at an authorized Porsche dealer.Tires must never be repaired under any circumstances.fIf Tire Pressure Monitoring System is defective (e.g. defective wheel transmitter), contact an authorized Porsche dealer immediately and have the damage repaired. The tire pressure will not be monitored at all or will be monitored only partially when Tire Pressure Monitoring System is defective.
For information on warning messages on the multi- purpose display:fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.fIncomplete entries or selection of the wrong tires on the multi-purpose display affect the accuracy of warnings and messages.The settings in the tire pressure menu must be updated following a wheel change or changes in vehicle loading.fUse only the pressure differences shown in the “ Fill info” display in the Tire pressure menu or from the corresponding tire pressure warning when correcting the tire pressure.fTires can lose air over time without a tire defect being present. A tire pressure warning
will then appear on the multi-purpose display.Check the tire pressure at the next opportunity.
Warning light
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.The TPMS malfunction indicator is combined with the low tire pressure telltale.When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.fAlways check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

Selecting load in the TPMS menu
fAdapt the pressure of the tires to the selected load type.Please see the chapter “VIEWING FILL INFO IN THE TPMS MENU” on page 108.
Information
If this menu is not displayed, the specified tire pressures are valid for all types of vehicle load.
Selecting comfort/standard pressure in the TPMS menu
For speeds up to 165 mph (270 km/h), the tire pressures can be reduced to increase suspension comfort.If you select “ Comfort press.”, the TPMS system automatically uses lower pressure values when monitoring tire pressure.
If “ Comfort press.” is deactivated or standard pressure is activated, the standard required pressures suitable for speeds up to the maximum vehicle speed are automatically monitored.
The comfort tire pressures are included in the technical dataorin “ Fill info” when the “Comfort press.” menu is activated.
Prolonged driving at low tire pressure or even short-term driving at high speeds on tires which have too low a pressure is likely to result in a loss of control of your vehicle, either due to a failure to maintain directional control under side loads or due to tire failure.
Tires are inflated to comfort pressure at the factory, which is not suitable for driving at very high speeds.fAlways adjust the pressure in the tires to the standard pressure setting when driving at higher speeds.fRemember to adjust the setting in the Tire Pressure Monitoring System accordingly.

“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.

Yellow warning – “Top off air”
The pressure in the tire is more than 4 to 7 psi/ 0.3 to 0.5 bar/30 to 50 kPa too low. The tire pressure warning specifies the affected tire and the target tire pressure. fFill up with air at the next opportunity.
This tire pressure warning appears: – for approx. 10 seconds when the vehicle is stationary and the ignition is switched off or – when the ignition is switched on again.
The warning can be acknowledged when the ignition is switched on.The tire pressure warning light in the instrument panel goes out only when the tire pressure has been corrected (differential pressure value “0.0”).
Red warning – “Check tires”
At speeds below 100 mph (160 km/h): – The pressure in the tire has dropped by 20 % below the required pressure or by more than 7 psi/0.5 bar/50 kPa . This significant pressure loss is a danger to road safety.
At speeds above 100 mph (160 km/h): – The pressure in the tire has dropped by more than 6 psi/0.4 bar/40 kPa . This significant pressure loss is a danger to road safety.fWhen the tire pressure warning appears, stop immediately at a suitable location. Check the indicated tire for signs of damage. If necessary, fill in tire sealant and set the correct tire pressure.
This tire pressure warning also appears when driving and can be acknowledged. The tire pressure warning light in the instrument panel goes out only when the tire pressure has been corrected (differential pressure value “0.0”).
“Tire pressure Reduce speed” warning
At speeds above 165 mph (270 km/h): – The pressure in the tire has dropped by more than 4 psi/0.3 bar/30 kPa . This pressure loss is a danger to road safety.fWhen the tire pressure warning appears, reduce speed to below 165 mph (270 km/h) until the warning disappears.When driving at very high speeds, increase the tire pressure to the required pressure (differential pressure value “0.0”).
