Car with FIS and tire air monitoring system
The tire pressure monitoring system indicates a drop in air pressure.
The tire pressure monitoring system monitors the set air pressure of the four impellers while driving and, if the pressure drops, warns the driver by illuminating the symbols and displaying the corresponding indication on the FIS display. The system works with wheel-mounted sensors. The radio signals from these sensors are transmitted to the tire pressure monitoring system.
The condition for air pressure control is its preliminary adjustment in accordance with the vehicle load and subsequent entry into the system memory (set pressure).
Note. The system helps the driver to control the air pressure in the tires, which, however, does not relieve the driver of the responsibility for air pressure.
Tire pressure drop
The red symbol indicates a large drop in air pressure.
When the air pressure drops by more than 0.4 bar, the red tire symbol lights up on the FIS display along with the symbol of the corresponding wheel.
For example, additional text REIFENDRUCK HINTEN LINKS (air pressure rear left) means a drop in air pressure of the rear left wheel.
In this case, immediately stop and take appropriate measures.
Pressure drop alarm
The yellow symbol indicates a decrease in air pressure.
If the air pressure drops by more than 0.2 bar, the yellow tire symbol lights up on the FIS display along with the symbol of the corresponding wheel.
Additional letter abbreviations:
- VL - front left wheel
- VR - front right wheel
- HL - rear left wheel
- HR - rear right wheel
The illustration shows the air pressure drop of the left front wheel as an example.
When the yellow symbol lights up, check and correct the air pressure as soon as possible.
Entering air pressure data into memory
It is a condition for normal operation of the tire pressure monitoring system that the preset pressure is re-entered at each wheel change.
The following is required for the tire pressure monitoring system to function:
Air pressure correction
- Check the air pressure of all vehicle wheels (including spare wheel).
- If necessary, correct the pressure in accordance with the standards given on the label affixed to the inside of the filler cap.
Entering air pressure data into memory
- Turn on the ignition.
- Press the Menu key. The start menu appears.
- Turn the rotary / push button to set the command selection arrow to EINSTELLEN (setting).
- Confirm the selection by pressing the rotary/press button. The EINSTELLEN submenu appears (setting).
- Turn the rotary / push button to set the command selection arrow to REIFENDRUCK (air pressure).
- Confirm the selection by pressing the rotary/press button. REIFENDRUCK submenu appears (air pressure).
- Set command select arrow to DRUCKE SPEICHERN (memorize air pressure data).
- Confirm the selection by pressing the rotary/press button. A checkmark appears. The correct entry into memory is confirmed by the system with the message DIE AKTUELLEN LUFTDRUCKE WURDEN GESPEICHERT (the current air pressure data is entered in. memory)
- Set Command Select Arrow to ZURUCK (back).
- To exit the REIFENDRUCK menu (air pressure) press the rotary/push button.
After the above-described entry into the air pressure data memory (DRUCKE SPEICHERN) the automatic programming process of the system starts.
Every time the air pressure is changed or a wheel is changed, a new memory entry is required via the DRUCKE SPEICHERN command (memorize pressure data). Only after that the system knows the set pressure and, if necessary, it can signal its drop.
Programming process
After entering the preset pressure data into the memory, the programming process begins.
The programming process begins after entering the air pressure data into the memory. It proceeds automatically and, as a rule, imperceptibly for your attention. The duration is several minutes.
The system measures and memorizes the actual air pressure data, and also checks the likelihood of a wheel change.
At the programming stage, the performance of the system is limited. This means that the signal indication is only possible if the air pressure drops by more than 0.4 bar in one or more wheels (also in the spare wheel). In this case, a red signal symbol appears with text information REIFENDRUCKE PRUFEN (check tire pressure).
Faults
In the event of malfunctions, the corresponding indication is displayed.
No access to the system
If there is no access to the system, a crossed-out bus symbol appears on the FIS display. Possible reasons for the appearance of this symbol:
- The appearance of this symbol at the end of the programming process may mean that the system does not recognize the wheels mounted on the vehicle. The reason may be the installation of one or more wheels without a sensor.
- Failure of the sensor or other components.
- The system identifies more than 5 vehicle wheels, for example when transporting several spare wheels in the vehicle.
- After changing a wheel, the air pressure data was not entered into the memory (function REIFENDRUCKE SPEICHERN).
- During the operation of snow chains, due to the shielding properties of the chains, a malfunction of the system may occur. The system turns off.
Eliminate the fault if possible and finally call the REIFENDRUCKE SPEICHERN function again. Contact Audi if you are unable to rectify the problem.
functional impairment
Temporary disturbance in the system can be caused by strong electromagnetic fields. When you are in the zone of such fields, a functional violation message appears: next to the crossed-out bus symbol, a lightning symbol appears.
Large difference in air pressure between the wheels of one axle
If, during the programming phase, the system detects a difference in air pressure between the wheels of one axle of more than 0.4 bar, then in this case a message appears on the FIS display indicating the corresponding wheels, for example, VL and VR (front left and front right).
Note. When changing tires, it is not allowed to remove or change sensors and valves. Only the valve spool should be replaced. Change valve and wheel electronics only if necessary.
Turning the system off and on
The driver has the option to turn off the system.
The tire pressure monitoring system can be disabled as follows:
- Call REIFENDRUCK menu (air pressure).
- Set command selection arrow to EIN.
- If there is a checkmark y, press the rotary/push button. A square appears ("No").
- Set Command Select Arrow to ZURUCK (back).
- To exit the REIFENDRUCK menu (air pressure) press the rotary/push button.
With the tire pressure monitoring system turned off, as a reminder to the driver, each time the ignition is switched on, the yellow tire symbol with the text AUS appears briefly on the FIS display (turned off).
