CHANGING A FUSE
Fuses
WARNING
Always replace a fuse with one that
has the specified amperage rating.
Using a fuse with a higher amperage
rating can cause severe wire damage and
could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.

VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.
WARNINGS
Exercise great caution when working
on a vehicle equipped with an
automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature or
the refrigerant pressure (if equipped with
air conditioning) reaches a predetermined
setting. The fan starts at this point with no
advance warning. Never reach near, or
permit objects to protrude into, the fan
blade radius while the engine is running as
this could result in vehicle damage,
personal injury or death. WARNINGS
Do not operate the vehicle if any
suspension conditions listed in the
following charts are evident. Loss of
steering or suspension could result in
property damage, personal injury or death. If a wheel must be changed, obtain
expert tire service help. Mounting and
un-mounting of tires should only be
performed by a qualified technician using
necessary safety procedures and
equipment, otherwise the result could be
property damage, personal injury or death. Note:
Always make sure you apply the
parking brake before starting the engine. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See Engine Oil Dipstick (page 190).
Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 198).
Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check
(page 205).
Power steering fluid
Remove the master cylinder caps and inspect the fluid level.
See
Brake Fluid Check (page 205).
Brake fluid

F650750 (TBC) , enUSA, Edition date: 201708, First Printing Vehicle Inspection Guide

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.
