CHANGING A FUSE
Fuses
WARNING: Always replace a fusewith one that has the specifiedamperage rating. Using a fuse with ahigher amperage rating can cause severewire damage and could start a fire.If electrical components in the vehicle arenot working, a fuse may have blown. Blownfuses are identified by a broken wire withinthe fuse. Check the appropriate fusesbefore replacing any electricalcomponents.

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be nomore than 5-7 cracks per rib, per 1 in (2.5 cm)Belts (fan, alternator,water pump and airconditioningcompressor)
Inspect for signs of fluid puddles or dripping fluid on theground under the engine, or the underside of the engine.Fluid leaks
Inspect for debris that may have collected on the HVAC airinlet grille or inside the exterior module as this may reducesystem performance.
HVAC air inlet
Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equippedwith spare electrical fuses (if used), three red reflectivetriangles, a properly charged and rated fire extinguisher andwheel chocks.
Safety and emergencyequipment
Walk around the vehicle and verify all steps and grab handles,inside and out (as well as behind), are tight and clean. Useextreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is inneutral (N) or park (P) (if equipped with a park position).Starting the engine
Diesel engine: Turn the key to the on position. Turn the keyto start when the wait to start indicator light in the instrumentcluster turns off.
Gasoline engine: Turn the key to start, and then release itas soon as the engine starts.
Verify pressure builds to normal operating range.Engine oil pressure
A tone indicating low air pressure should sound immediatelyafter the engine starts but before the compressor has built-up pressure. The tone should stop when the air pressurereaches 70 psi (483 kPa). Let the air pressure build togoverned cutout pressure, which should occur between115–130 psi (793–896 kPa).
Low air pressure warningtone (if equipped with anair compressor)
Press the accelerator and verify that it operates smoothly,without any binding or irregular feel. Release the pedal andverify the engine returns to idle speed immediately.
