284 Service and Maintenance
G: Exhaust System : Be alert for any
changes in the sound of the exhaust system
or any smell of fumes. These are signs the
system may be leaking. Have it checked
and/or repaired at once. (Refer to "Engine
Exhaust Emissions Caution (Carbon
Monoxide)" under Engine Exhaust 0 145).
H: Windshield Wipers and Washers : Check
operation and condition of the wiper blades.
Check the flow of the washer spray.
I: Defroster : Turn the outlet selector knob
to "Defroster" and the fan speed control
knob to the fully clockwise position. Then
check the airflow from the ducts at the
inside base of the windshield.
J: Rearview Mirrors and Sun Visors : Check
that friction joints hold mirrors and sun
visors in place.
K: Horn : Sound the horn, now and then, to
be sure it works.
L: Lap-Shoulder Belts : Check the seat belt
system (including webbing, buckles, latch
plates and anchors) for proper operation,
and for damage.
M: Seat Adjusters : When adjusting the
driver's manual seat, be sure the seat
adjusters latch by pushing the seat forward
and backward. Do not attempt to adjust the
seat when the vehicle is in motion.
N: Lamps : Check panel lighting, warning
lamps, indicator lamps and interior lamps.
On the outside, check: license plate lamps,
side marker lamps, reflectors on outside
mirrors, headlamps, parking lamps,
identification and clearance lamps, taillights,
brake lamps, turn signals, cornering lamps,
backup lamps and hazard warning flashers.
Have headlamp aim checked immediately if
beams seem improperly aimed.
O: Glass, Mirrors, Lights and/or Reflectors
Condition : Look for broken, scratched, dirty
or damaged glass, mirrors, lamps or
reflectors that could reduce the view or
visibility, or cause injury. Replace, clean or
repair promptly.
P: Door Latches : Check that doors close,
latch and lock tightly. Check for broken,
damaged or missing parts that might
prevent tight latching.
Q :Tilt Cab (Driving Position) : Be sure the
tilt lever is pulled up and locked.
R: Fluid Leaks : Check for fuel, water, oil or
other fluid leaks by looking at the surface
beneath the vehicle after it has been parked
for a while. If you notice diesel fumes or
fluid at any time, have the cause found and
corrected at once.
S: Underbody : Corrosive materials used for
ice removal, snow removal and dust control
can collect on the underbody. If these
materials are not removed, accelerated
corrosion (rust) can occur on underbody
parts such as fuel lines, frame, floor pan and
exhaust system. At least every spring, flush
these materials from the underbody with
plain water. Take care to clean well any
areas where mud and other debris can
collect. Sediment packed in closed areas of
the frame should be loosened before being
flushed.

Abnormalities during Previous Operation

abnormalities during the previous operation.
