- brake system malfunction

When a flashing red symbol appears, three consecutive warning sounds are heard. The symbols signal a danger. Stop, turn off the engine, check the failed system and eliminate the malfunction. This may require qualified assistance. If several first-priority failures occur at once, the symbols appear on the display sequentially, with each indication lasting 2 seconds. The symbols continue to flash until the malfunction is eliminated.
