INSTRUMENTS AND CONTROLS 57
CAUTION The maximum safe oil temperature for MACK transmissions is 121°C (250°F) for mineral-based oil, or 148°C (300°F) for synthetic oil. Continued operation with oil above this temperature will cause rapid deterioration of the oil’s lubricating properties and is NOT recommended. Consult the vendor manual for non-MACK components.
6. Integrated Temp-A-Start (Amber) (If Equipped) – "Integrated Temp-A-Start" saves fuel by reducing the amount of time spent idling to keep the vehicle’s batteries charged, the engine warm, or the cab and sleeper comfortable. Once the optional ’Integrated Temp-A-Start’ feature is activated via a dash switch, the system will automatically start and stop the truck engine. Safety overrides prevent the system from activation if the transmission is in gear, the hood is up, or the parking brake is released. Integrated Temp-A-Start voltage and temperature target settings are fully programmable through either VCADS service support software, or, if enabled via the Co-Pilot instrument cluster display. 7. Wait to Start (Amber) (If Equipped) – Indicates that the intake pre-heat is enabled. Wait to start engine until light goes out. 8. Check Transmission Indicator (Amber) –Indicates that the transmission oil temperature is above the warning limit. 9. On Board Diagnostics Indicator (Amber) - Indicates the need to access the on board diagnostics port for information. 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. High Beam Indicator (Blue) – Indicates that high beams are on. 12. Left Turn Signal Indicator (Green) – Flashes green when the left turn signal is activated. 13. Parking Brake – Indicates that the parking brake is engaged.
