STANDARD GAUGES CAUTION: Keep the engine running if the engine is overheating and the low coolant alarm is not on. Allowing the engine to run with coolant in the system will help protect the engine from overheating whick will reduce the damage to the engine. • With the transmission in neutral, check to be certain the oil pressure gauge reads normal. Increase the engine speed to about 1100 - 1200 RPM, maximum. Return the idle speed to normal after 2 or 3 minutes. If the warning light does not go off or the temperature gauge does not begin to drop, then turn the engine off. • If the overheating came from severe operating conditions, the temperature should have cooled by this time. If it has not, stop the engine and let it cool before checking to see if the coolant is low. Fuel Gauge CONTROLS AND DISPLAY WARNING! Do not remove a fuel tank cap near an open flame. Hot fuel vapors are combustible and can cause an explosion or fire resulting in death, injury or property damage. CAUTION: Use Ultra Low Sulfur Diesel fuel only. Failure to do so may damage components of the engine and Diesel Particulate Filter (DPF). – 42 – Y53-6027 Medium Duty (R05/09)

CONTROLS AND DISPLAY CAUTION: The fuel gauge shows the approximate amount of fuel in the fuel tanks. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. You will want to keep your fuel tanks at least half full to reduce condensation of moisture in the tanks. This moisture can damage your engine. Diesel Exhaust Fluid (DEF) Gauge STANDARD GAUGES capacity. DEF fluid is required to meet certain emission requirements. Do not allow your DEF tank to remain empty. Please refer to your emission supplemental manual for more details about DEF fluid. CAUTION: Use Diesel Exhaust Fluid only. Failure to do so may damage components of the Diesel Particulate Filter (DPF). Primary (Secondary) Air Pressure Gauge (Air Reservoir) The air pressure gauge indicates the amount of air pressure in the brake system in pounds per square inch (psi). • The primary gauge shows front reservoir air pressure. • The secondary gauge shows pressure in the rear reservoir. The deisel exhaust fluid gauge shows the approximate amount of DEF fluid in the DEF tank. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total Ensure the air pressure registers more than 100 psi in both service systems before you move the vehicle. If the pressure in either circuit is too low for normal brake operation, the warning light will glow and the audible alarm will sound. Medium Duty (R05/09) Y53-6027 – 43 –
