If equipped with an air inlet heater (AIH) for cold weather starting, do not use types of starting aids such as ether. Such use could result in an explosion and injury.
When starting the engine with ether, follow these starting procedure instructions carefully. Use ether sparingly and spray it ONLY WHILE CRANKING THE ENGINE. Excessive ether use can cause piston and ring damage. Ether should be used only for cold weather starting.
