Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm) Belts (fan, alternator,
water pump and air
conditioning
compressor)
Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine. Fluid leaks
Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance. HVAC air inlet
Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equipped
with spare electrical fuses (if used), three red reflective
triangles, a properly charged and rated fire extinguisher and
wheel chocks. Safety and emergency
equipment
Walk around the vehicle and verify all steps and grab handles,
inside and out (as well as behind), are tight and clean. Use
extreme 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 in
neutral (N) or park (P) (if equipped with a park position). Starting the engine
Diesel engine: Turn the key to the on position. Turn the key
to start when the wait to start indicator light in the instrument
cluster turns off.
Gasoline engine: Turn the key to start, and then release it
as soon as the engine starts.
Verify pressure builds to normal operating range. Engine oil pressure
A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches 70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115–130 psi (793–896 kPa). Low air pressure warning
tone (if equipped with an
air compressor)
Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately. Accelerator
