Audi Q7: Tire pressure monitoring system

General notes

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 telltale.

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. Always 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.

If the tire pressure monitoring indicator appears

Applies to: vehicles with Tire Pressure Monitoring System indicator

The tire pressure indicator in the instrument cluster informs you if the tire pressure is too low or if there is a system malfunction.

Using the ABS sensors, the tire pressure monitoring system compares the tire tread circumference and vibration characteristics of the individual tires. If the pressure changes in one or more tires, this is indicated in the instrument cluster display with an indicator light and a message.

If only one tire is affected, the location of that tire will be indicated.

The tire pressures must be stored again each time you change the pressures (switching between partial and full load pressure) or after changing or replacing a tire on your vehicle. The tire pressure monitoring system only monitors the tire pressure you have stored.

Refer to the tire pressure label for the recommended tire pressure for your vehicle fig. 173.

Tire tread circumference and vibration characteristics can change and cause a tire pressure warning if:

• The tire pressure in one or more tires is too low
• The tires have structural damage
• The tire was replaced or the tire pressure was changed and it was not stored
• Tires that are only partially used are replaced with new tires

Indicator lights

If the indicator light turns on, there is a loss of pressure in at least one tire .

Check the tires and replace if necessary. Check and correct the pressures of all four tires and store the pressure again.

Tire pressure: malfunction! See owner's manual

If appears after switching the ignition on or while driving and the indicator light in the instrument cluster blinks for approximately one minute and then stays on, there is system malfunction.

Try to store the correct tire pressures. In some cases, you must drive for several minutes after storing the pressures until the indicator light turns off. If the indicator light does turn off or turns on again after a short period of time, drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.

WARNING

• If the tire pressure indicator appears in the display, reduce your speed immediately and avoid any hard steering or braking maneuvers.

  Stop as soon as possible and check the tires and their pressure.

• The driver is responsible for maintaining the correct tire pressure. You must check the tire pressure regularly.
• Under certain conditions (such as a sporty driving style, winter conditions, or unpaved roads), the tire pressure monitoring system indicator may be delayed.

Tips

• The tire pressure monitoring system can also stop working when there is an ESC malfunction.
• Using snow chains may result in a system malfunction.
• The tire pressure monitoring system in your Audi was calibrated with "Audi Original Tires". Audi recommends using these tires.

Storing tire pressures

Applies to: vehicles with Tire Pressure Monitoring System indicator

If the tire pressure changes or a tire is replaced, it must be confirmed in the system.

• Before storing the tire pressures, make sure the tire pressures in all four tires meet the specified values and are adapted to the load.
• Switch the ignition on.
• Applies to MMI: Select on the home screen: VEHICLE
• Settings & Service > Tire pressure monitoring > Store tire pressure > Yes, store now.

Tips

Do not store the tire pressures if snow chains are installed.

General information

Applies to: vehicles with tire pressure monitoring system

The tire pressure monitoring system monitors the pressure in the four tires when driving.

The system uses sensors that measure the temperature and pressure in the tires. The data is sent from these sensors to the control module by radio frequency.

The tire pressure monitoring system shows the current pressures and temperatures of the tires in the MMI while driving. It also compares the current tire pressures with the stored tire pressures and gives a warning in the driver information system if the tire pressure is different from what is stored.

The system does not detect if the stored tire pressures match the recommended tire pressures.

You must store the tire pressures again in each of the following situations:

• Each time the tire pressures change, for example when the load in the vehicle changes
• After replacing a tire
• If wheels with new wheel sensors are used

WARNING

• The tire pressure monitoring system assists the driver in monitoring tire pressures. The driver is responsible for having the tires inflated to the correct pressure.
• Do not change the tire pressure when the temperature of the tire is extremely high.
  This could result in serious damage to the tire and even cause the tire to burst, increasing the risk of an accident.
• A tire with low pressure flexes more. This heats the tire up too much. This could cause the tread to separate and even cause the tire to burst, increasing the risk of an accident.
• The tire pressure monitoring system does not warn about damage or defects in the tire construction that could cause the tire to burst, for example. Inspect your tires regularly.

Tips

• If tires are replaced, the sensors and valves do not need to be removed or replaced. Only replace the valve stem and, if necessary, the valve and the wheel electronics. If you have questions, see an authorized Audi dealer or authorized Audi Service Facility.
• An incorrect display or a malfunction in the tire pressure monitoring system can occur after using the tire mobility kit*. Have the sensors replaced by an authorized Audi dealer or authorized Audi Service Facility.
• The system complies with United States FCC regulations and ISED regulations.

Displaying tire pressure and temperatures

Applies to: vehicles with tire pressure monitoring system

Requirement: you must be driving the vehicle.

• Applies to MMI: Select on the home screen: VEHICLE > Settings & Service > Tire pressure monitoring > Display tire pressure.

The current tire pressures are shown in green, yellow, or red numbers:

• Green: the current tire pressure and the specified tire pressure are approximately the same.
• Yellow: the current tire pressure is lower than the specified tire pressure.
• Red: the current tire pressure is much lower than the specified tire pressure.

The specified tire pressure is the last tire pressure that was stored.

Note that the tire pressure also depends on the temperature of the tire. The tire pressure increases as the tires become warmer while driving.

WARNING

Read and follow the important information and notes.

Tips

The tire pressure or temperature is not displayed while the vehicle is stationary and in adaptation mode. Dashes --.-- are shown in place of the pressure and temperature.

Tire pressure loss

Applies to: vehicles with tire pressure monitoring system

If the indicator light turns on, the tire pressure is too low compared to the specified pressure.

Check and store the tire pressure(s) the next time it is possible.

Flat tire! Safely stop vehicle. Please check all tires and store pressures in MMI

If the indicator light turns on and the message appears, the tire pressure has reached a critical level compared to the specified pressure. Avoid unnecessary steering and braking maneuvers.

Adapt your driving style to the situation. Stop as soon as possible and check the tire(s). If it is possible to continue driving, see an authorized Audi dealer or authorized Audi Service Facility immediately and have your tire(s) repaired or replaced if necessary.

WARNING

Read and follow the important information and notes.

Storing new tire pressures

Applies to: vehicles with tire pressure monitoring system

The tire pressure specifications must be stored correctly for the tire pressure monitoring system to function reliably.

It is always necessary to store the tire pressures when the tire pressures are modified, for example due to a change in load or when new sensors are installed.

• Before storing the tire pressures, make sure the tire pressures of all four tires meet the specified values and are adapted to the load, fig. 173. Only correct and store the pressure in tires whose temperature is approximately the same as the ambient temperature.

  If the temperature of the tire is higher than the ambient air temperature, the tire pressure must be increased approximately 3 PSI (0,2 bar) above the value on the sticker.

• Switch the ignition on.
• Applies to MMI: Select on the home screen: VEHICLE > Settings & Service > Tire pressure monitoring > Store tire pressure > Yes, store now.
• If the changed tire pressures are not displayed on the MMI, drive the vehicle for approximately 10 minutes so that the sensor signal from the wheels is received again.

During this adaptation phase, --.-- is displayed for the pressure and temperature and the tire pressure monitoring system is only partially available. It only provides a warning if one or more tire pressures is below the minimum permitted specified pressure.

Tire pressure: wheel change detected. Please check all tires and store pressures in MMI

If the indicator light turns on and the message appears, the system has detected that the location of the sensors has changed due to a wheel replacement, or new sensors have been installed.

Store the new tire pressures.

WARNING

Read and follow the important information and notes.

Malfunctions

Applies to: vehicles with tire pressure monitoring system

Tire pressure: malfunction! See owner's manual

If the indicator light appears after switching the ignition on or while driving and the indicator light also blinks for approximately one minute and then stays on, then there is system malfunction.

The following are examples of situations that could cause a malfunction:

• If the message appears at the end of the adaptation phase, the system may not detect one or several of the wheel sensors necessary for pressure monitoring. This may result from one or more wheels without wheel sensors or with incompatible wheel sensors being installed.
• A wheel sensor or another component has failed.
• Using snow chains can affect the function of the system because of the shielding effect of the chains.
• The tire pressure monitoring system is not available due to a malfunction.
• Transmitters with the same frequency, such as headphones or remote controlled devices, may cause a temporary system malfunction due to the strong electromagnetic field.

The indicator light and the message turn off once the tire pressure monitoring system is available again. If you cannot correct the malfunction and the indicator light stays on, drive immediately to an authorized Audi dealer or authorized Audi Service Facility to have the malfunction repaired.
