Red symbols



The red symbol signals danger.

The red symbol signals danger.


When the symbol appears:
  • Stop.
  • Turn off the engine.
  • Check the faulty function. If necessary, seek qualified assistance.

The meaning of the red symbols:

The meaning of the red symbols:


Red symbols indicate a malfunction of the first priority level (danger).

When the red symbol appears, three consecutive warning beeps will sound.

The symbol continues to flash until the fault is corrected.

If several first-priority malfunctions occur at once, the symbols appear sequentially, with each display lasting 2 seconds.



Brake system failure

Correct the brake system fault as soon as possible.

Flashing symbol 0 on the display indicates a malfunction in the brake system.
  • Stop.
  • Check the brake fluid level.

If the ABS fails, the indicator lamp lights up together with the brake system malfunction symbol 0.

Attention
  • A drop in the brake fluid level in the filler tank means a risk of accident! Further driving is not permitted. Seek qualified assistance.
  • The reason for the brake system warning light coming on together with the ABS warning light may be a failure of the ABS control function. As a result, relatively rapid locking of the rear wheels may occur when braking. Under certain circumstances, this may lead to skidding of the rear axle of the vehicle - risk of skidding! Drive carefully to the nearest specialist facility and have the fault rectified.


Cooling system malfunction

Eliminate the cooling system malfunction immediately.

The reason for the symbol flashing while driving may be overheating or a drop in the coolant level.
  • Stop.
  • Turn off the engine.
  • Check the coolant level.
  • Add coolant if necessary.
  • Continue moving only after the symbol goes out.
  • If necessary, seek qualified assistance.

If the coolant level is normal, then the cause of overheating may be a failure of the cooling system fan.

If the battery discharge indicator light also lights up, the cause may be a broken poly V-belt.

Warning. Never open the hood if you see or hear steam or coolant coming out of the engine compartment - risk of burns! Wait until the steam or coolant stops coming out.




Caution: Do not continue driving if the symbol indicates a fault in the cooling system - risk of engine damage.


Malfunction in the engine oil pressure system

Immediately correct the malfunction in the engine oil pressure system.

Flashing of the symbol on the display indicates that the oil pressure has dropped below normal.
  • Stop.
  • Turn off the engine.
  • Check the engine oil level.
  • If necessary, seek qualified assistance

Engine oil level drops below normal

Top up engine oil if its level drops below normal.

Normal engine oil level

Do not continue driving if the symbol is flashing when the oil level is normal. Also, do not allow the engine to idle - seek qualified assistance.

Note: The oil pressure indicator lamp is not an indicator of the oil level in the lubrication system. Therefore, check the oil level regularly, preferably when refuelling.


Tire pressure drop

If the air pressure in the tires is low, bring it back to normal as soon as possible.

The appearance of the symbol indicates a drop in air pressure in the tire of at least one wheel.
  • Stop.
  • Check pressure/tires.
  • Replace the wheel if necessary.

The symbol always appears in combination with additional text information, e.g. REIFENDRUCK HINTEN RECHTS (air pressure in the rear right tire).

The appearance of the symbol in combination with additional information REIFENDRUCKE PRUFEN (check tire pressure) may indicate a drop in air pressure in several tires, including the spare tire.

The display may also show a yellow symbol. This symbol means that the air pressure needs to be checked.

Brake light malfunction

Cars with FIS and on-board computer

If the BREMSLICHT symbol or display lights up, the following must be checked and, if necessary, replaced or repaired at an Audi facility:
  • brake light bulbs,
  • connections in electrical wiring,
  • brake light switch.

Replacement/repair must be carried out at the Audi facility.

Malfunction of low beam, reversing lights

If the symbol lights up, check the following components:
  • low beam incandescent lamps
  • reversing light bulbs
  • connections in electrical wiring.

Replacement/repair must be carried out at the Audi plant.

Note: This function is controlled by the malfunction monitoring system only when the light is on.


Front brake lining wear

If the symbol appears, contact an Audi dealer to have the front brake pads checked (and for the safety of the rear) wheels.



Windscreen washer fluid level drop

Car with FIS with on-board computer
The appearance of the symbol means that it is necessary to add washer fluid to the windshield washer and headlight cleaning device filling tank.

Low fuel supply

If this symbol lights up for the first time, it means that there are about 7-8 liters of fuel left in reserve. It is necessary to refuel the car as soon as possible.

Battery voltage deviation from normal

Car with FIS and on-board computer

If the symbol appears, contact an Audi dealer and have the following components checked:
  • v-belt
  • voltage regulator
  • battery status

Also remember about the low battery indicator light.

The voltage of the on-board network can also be monitored using a voltmeter.

Check the engine oil level

When the symbol appears, check the oil level as soon as possible and top up if necessary.

Engine oil sensor malfunction

If the symbol appears, contact an Audi dealer to have the oil level sensor checked. Before that, for safety reasons, check the oil level every time you fill up the vehicle with fuel.

Speed alarm

Car with FIS and on-board computer

The appearance of the symbol means that the actual speed has exceeded the entered speed value. Reduce speed.

Malfunction of the headlight range adjustment device

Vehicles with dynamic headlight leveling device

When the symbol appears, the dynamic headlight range control is faulty. Contact Audi to have the headlight range control repaired.

Tire pressure drop alarm

Vehicles with tire pressure monitoring system

When the symbol lights up, it means that the air pressure in the tire needs to be checked and adjusted.



The symbol always appears together with the letter designation of the corresponding wheel, for example, VR means front right wheel.

Speed alarm

Car with FIS and on-board computer

The speed alarm allows you to set a speed limit that should not be exceeded.

The speed alarm allows you to set a speed limit that should not be exceeded.


The speed alarm warns the driver that a pre-set speed has been exceeded. As soon as the actual speed exceeds the set value by approximately 10 km/h, a warning signal sounds. At the same time, a warning symbol appears on the display.

The speed alarm allows you to program two warning levels that operate independently of each other and perform slightly different tasks.

Warning Level 1: Function



Car with FIS and on-board computer

The value of warning level 1 can be changed while driving.

Warning level 1 enables the speed limit to be set while driving. The entered speed value is stored in memory until the ignition is switched off, unless the speed has been changed or the entered limit has been cancelled beforehand.

The first warning level signal symbol appears on the display when the actual speed exceeds the entered value. The symbol goes out when the speed decreases below the programmed sign.



The symbol also goes out if the entered speed value is exceeded by approximately 40 km/h for at least 10 seconds. However, the memory data for the entered speed limit is not reset.

Warning Level 1: Programming

Car with FIS and on-board computer

Warning level 1 is programmed via the setting/control button.

Warning level 1 is programmed via the setting/control button.


Programming the speed limit
  • The vehicle must move at the current speed, which must not be exceeded.
  • Press and release the setup/control button.

Cancellation of the imposed speed limit
  • The vehicle speed must be more than 5 km/h.
  • Press the setup button/control button for more than 1 second.

Successful entry into the memory is confirmed by the signal symbol 0) of the speed limit briefly lighting up on the display when the button is released. The entered speed value remains in the memory until the next short press of the button at a different speed or until you cancel the entered limit by pressing it for more than 1 second.

Warning Level 2: Function



Car with FIS and on-board computer

The value of warning level 2 can only be changed when the ignition is switched off.

Warning level 2 will enable programming and cancellation of the maximum speed limit only when the ignition is switched off. Programming this warning is recommended when a general reminder to the driver to maintain a certain maximum speed is required. For example, when driving in a country with a speed limit, the maximum speed when driving with winter tires.

The warning level 2 signal symbol appears on the display when the actual speed exceeds the entered value. The symbol, unlike warning level 1, only goes out when the speed drops below the programmed value.

Warning Level 2: Programming

Car with FIS and on-board computer

Warning level 2 is programmed and cancelled by switches mounted in the windscreen wiper handle.
