Maintenance and Specifications FUELING WARNING: Do not use starting fluid such as ether or gasoline in the diesel air intake system. Such fluids can cause immediate explosive damage to the engine and possible personal injury. If you fuel your vehicle at a truck stop, you may notice that the fuel nozzle may shut off every 5-10 seconds. This is due to the flow rates being designed for larger heavy duty trucks. You may have to fuel at a slower rate (don't depress the nozzle trigger fully). Do not run your diesel vehicle out of fuel as this will allow air to enter the fuel system which will make restarting difficult. Longer engine cranking time may be required once air is in the fuel system. If air enters the fuel system (either through running the fuel tank(s) empty or during a fuel filter change), the engine will self-purge the trapped air once it starts running. The engine may run roughly and produce white smoke while air is in the fuel system; this is normal and should stop after a short time. MINOR TROUBLESHOOTING GUIDE Air purge procedure Turn the key on for 30 seconds, then turn off. Repeat the procedure six times. If the engine won't crank WARNING: Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling. Turn on the headlights. If the lights are dim, do not go on at all or when the ignition is turned to START the lights become dim or go out, the battery connections may be loose or corroded, or the battery may be discharged. If there is a clicking or stuttering sound coming from the engine compartment when you turn the key to START, this may also indicate a loose or corroded battery connection. Check the battery connections at the battery posts, cable connection to the engine grounding point and at the starter connection. If a discharged battery is suspected, have it checked and corrected. • The gearshift lever must be in P (Park) or N (Neutral) in order for the starter to operate. 65 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)

FUELING
WARNING:
Do not use starting fluid such as ether or gasoline
in the diesel air intake system. Such fluids can cause immediate
explosive damage to the engine and possible personal injury.
If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5–10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don’t depress the nozzle trigger fully).
Do not run your diesel vehicle out of fuel as this will allow air to enter the
fuel system which will make restarting difficult. Longer engine cranking
time may be required once air is in the fuel system. If air enters the fuel
system (either through running the fuel tank(s) empty or during a fuel
filter change), the engine will self-purge the trapped air once it starts
running. The engine may run roughly and produce white smoke while air is
in the fuel system; this is normal and should stop after a short time.
