If equipped with an air inlet heater (AIH) for cold weather starting, do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury.
An air inlet heater is installed in the air inlet manifold. The air inlet heater is an electrical device which provides heated inlet air for cold weather starting.Note: Startability improves at temperatures below 16°C (60°F) with the use of the air inlet heater. This will help reduce white smoke and misfire during start-up in cold weather.Startability will be improved at temperatures below -18°C (0°F) from the use of a cylinder block coolant heater or extra battery capacity.When No. 2 diesel fuel is used, the following items provide a means of minimizing starting problems and fuel problems in cold weather: starting aids, engine oil pan heaters, engine coolant heaters, fuel heaters and fuel line insulation.For temperatures below -23°C (-10°F), consult your Caterpillar dealer.

Turn the battery disconnect switch to the ON position. The battery disconnect switch is inside the access door that is on the front of the battery box on the left side of the machine.
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
Turn the start switch key to the ON position. The system performs an automatic self-diagnosis. When you turn on the start switch key the test is performed. If the test is complete without any faults, proceed to the next step. If the system detects a fault, check the electrical system. Complete all of the necessary repairs before you start the engine.

(5) Air inlet heater
The indicator for the air inlet heater is positioned on the lower digital display window. The indicator light (5) will come on during the next cycle before engine start-up.
When indicator light (5) is on, the air inlet heater is in the ON or "preheat cycle". Do not attempt to start or crank the engine until the indicator light turns off.
When the indicator light goes off, turn the engine start switch key to the start position in order to start the engine.
Turn the start switch key to the START position. Crank the engine. When the engine starts, release the engine start switch key.
If the engine start key switch is turned to the OFF position before the engine is started, or if the engine does not start, allow the air inlet heater to cool for two minutes before the next attempt to start the engine.Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking the engine
