INSTRUMENTS AND CONTROLS 67
10. Electronic Malfunction Indicator (Amber) – Illuminates when V-MAC® detects an electronic malfunction. Refer to the V-MAC® IV Operator’s Guide. The electronic malfunction lamp may turn on when operating the vehicle in a bob-tail mode with the engine brake turned on and cruise control active. Cruise control will become inoperative but can be reset by shutting off, then restarting the engine. This condition can be corrected by resetting the "Service Brake Fault Threshold with Engine Brake" function. Refer to V-MAC® IV Customer Data Programming. Note: Consult the appropriate vendor engine manual if your vehicle is not equipped with a MACK engine. 11. Check Lamps 12. High Beam Indicator (Blue) – Indicates that high beams are on. 13. Parking Brake Indicator (Red) – Indicates that the parking brake is engaged. 14. Left Turn Signal Indicator (Green) – Flashes green when the left turn signal is activated.
15. Engine Shutdown Indicator (Red) – Indicates the occurrence of a condition which requires that the engine be shut down (i.e., low water level, low oil pressure or high water temperature). If the engine shutdown feature is enabled, the engine will be forced to idle. Once vehicle is stopped, the engine will shut down. If the engine shutdown feature is disabled, the indicator will function as a warning light but the engine will not shut down. 16. Aftertreatment DEF Low Level Indicator (DEF)– Icon illuminated when the fluid level is low. It also flashes when the level becomes critically low. 17. Anti-Lock Brake System (ABS) Indicator (Amber) – Indicates an ABS malfunction. If the light turns on and stays on, a malfunction is indicated. For additional information on operating an ABS-equipped vehicle, refer to “Anti-Lock Brake System (ABS)”, page 157of the Operationsection. Note: When an ABS malfunction is detected, anti-lock braking in the affected wheel(s) will be disabled and normal braking will return; the other wheels will retain anti-lock braking. Operate the vehicle normally and have the ABS system serviced to correct the fault. 18. Low Coolant Level Indicator (Amber) – Illuminates when the coolant level in the coolant surge tank is below the specified level. Stop and add coolant.
