Engine Air-Intake Heater Indicator This indicates that the engine's air intake heater is operational below 40°F (4°C), warming the engine for starting.
Transmission Temperature Warning Indicator Signals that the transmission oil temperature has exceeded safe levels require cooling.
Hydraulic Oil Temperature Warning Indicator Indicates the hydraulic oil is too hot, and the system needs to cool down to prevent damage.
Engine Oil Pressure Warning Indicator Warns of low engine oil pressure; the vehicle should be stopped and checked immediately.
Alternator Charging Warning Indicator Signifies a problem with the charging system, suggesting the alternator or batteries need checking.
Engine Air Filter Restriction Warning Indicator Illuminates when the engine air filter is clogged and requires servicing.
