Engine Operation - Except 4.5L Engines 5. Turn the key start switch (A) clockwise to crank the engine. When the engine starts, release the key switch so that it returns to the position. IMPORTANT: If the key switch is released before the engine starts, wait until the starter and the engine stop turning before trying again. This will prevent possible damage to the starter and/or flywheel. 6. After engine starts, idle engine at not more than 1200 rpm until warm. (See WARMING ENGINE later in this section). Panels with high-low speed select rocker switch (B) only: Set rpm using bump speed enable switch (C) with speed select rocker switch (D).

Start And Idle Engine On Earlier Panel (Left) or Later Panel (Right) NOTE: Engine control unit (ECU) reads the higher of the high-low speed select rocker switch or the analog throttle speed settings.

Check all gauges for normal engine operation. If operation is not normal, stop the engine and determine the cause.
