Warning lights Warning lights WAIT TO START With the key in the ON position, the WAIT TO START light will illuminate if glow plug heat is necessary as a starting aid. Wait until the light goes off before starting. The light should always illuminate briefly, when the ignition key is in the ON position. If the light does not illuminate, there may be a problem. Refer to the Starting chapter in this guide. After the engine starts, the light should remain off. WATER IN FUEL During refueling, it is possible for water-contaminated diesel fuel to be pumped into your tank. Your vehicle fuel system is equipped with an HFCM to remove water from the fuel. The WATER IN FUEL light will illuminate when the ignition is turned to START (as part of the light function check) and when the HFCM has a significant quantity of water in it. If the light illuminates when the engine is running, stop the vehicle as soon as safely possible, shut off the engine, then drain the HFCM. Refer to the General maintenance information chapter for drain procedure. Allowing water to stay in the system could result in extensive damage to, or failure of, the fuel injection system. 8
