High beam and turn signal indicators Function check All indicator and warning symbols light up in ignition mode II or when the engine is started. When the engine has started, all the symbols should go out except the parking brake symbol, which only goes out when the brake is disengaged. If the engine does not start or if the function check is carried out in ignition mode II , all symbols go out after 5 seconds except the 75 03 Your driving environment Instruments and controls symbol for faults in the vehicle's emissions system and the symbol for low oil pressure. Certain symbols may not have their functions illustrated, depending on the vehicle's equipment. Indicator and warning symbols Trailer turn signal indicator If you are towing a trailer, this light will flash simultaneously with the trailer's turn signals. If the light does not flash, or if they flash faster than usual when signaling a turn, the turn signals on the trailer or on the vehicle are not functioning properly. Malfunction Indicator Light As you drive, a computer called On-Board Diagnostics II (OBDII) monitors your vehicle's engine, transmission, electrical and emission systems. The malfunction indicator (CHECK ENGINE) light will illuminate if the computer senses a condition that potentially may need correcting. When this happens, please have your vehicle checked by a trained and qualified Volvo service technician as soon as possible.
