To be 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 ensure a proper vehicle inspection procedure. The pages in
this section may be produced locally and used on a regular basis.
VEHICLE INSPECTION INFORMATION
Note:Always make sure the parking brake is applied before starting the
engine.
Engine compartment (with engine stopped)
Engine oil level:Use the engine oil dipstick to verify that the
engine oil level is between the ADD and
OPERATING RANGE marks.
Engine coolant
level:Look through the plastic reservoir or the clear
sight glass on the reservoir, depending upon
vehicle equipment, and make sure the fluid is
within the minimum and maximum fluid level
range as marked on the reservoir.Do not
remove pressure cap until the coolant has
cooled.
Power steering fluid:Verify that the fluid level is between the
proper operating range Refer toPower
steering fluidin theMaintenance and
specificationschapter.
Brake fluid (master
cylinder):Remove the master cylinder caps and inspect
the fluid level. The full mark is at the bottom
of the opening of the port ring.
Hydraulic clutch
fluid:Check for adequate amount of hydraulic clutch
fluid. Fluid level should be at the step of the
reservoir; refer toClutch fluid/linkage
adjustmentsin theMaintenance and
Specificationschapter.
Belts (Fan,
alternator, water
pump and A/C
compressor):Check for glazing, fraying or cracking. There
should be no more than five - seven cracks per
rib per inch.

Wait to start:Indicates the air
intake heater is in operation and special starting procedures are
required. Refer to theDrivingchapter.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could result in damage
and/or personal injury.
Water in fuel:During refueling, it
is possible for water-contaminated
diesel fuel to be pumped into your
tank. Your vehicle fuel system is
equipped with a fuel filter/water
separator to remove water from the fuel. The WATER IN FUEL light will
illuminate when the fuel filter/water separator has a significant quantity
of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the fuel
filter/water separator. Refer toFuel filter/water separatorin the
Maintenance and Specificationssection for the drain procedure.
Allowing water to stay in the system could result in extensive damage to,
or failure of, the fuel injection system.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Traction control:Illuminates when
the traction control system is turned
off.

road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
Know the required stopping distances for all driving conditions that may
be encountered. For longer brake lining life, take full advantage of engine
braking power when coming to a stop.
Do not drive with your foot resting on the brake pedal. This will
result in abnormally high brake temperatures, excessive lining
wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you would use to ascend the hill.
Continuous application of the brakes will cause the brakes to
overheat, resulting in a temporary loss of braking.
If brakes do not grip well
•If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure. (Air brakes only)
HYDRAULIC BRAKES (IF EQUIPPED)
HydroMax brake booster system
The HydroMax systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The HydroMax booster receives back-up pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is off, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.
The sound of the pump operating or fluid flowing through the booster
may be heard; this is a normal characteristic of the system and should be
no reason for concern.
