Engine starting (with parking brake applied)
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor protection valve knob):
1. Check the air compressor or governor
cut-out pressure (approximately 305 kPa [120
psi]).
2. Cut-off the engine and turn the key back to
ON, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 5 kPa (2 psi) for single vehicle and 8
kPa (3 psi) for combination vehicles.
4. Depress and hold the brake pedal with 621
kPa (90 psi) or more and make sure there is
no more than a 8 kPa (3 psi) per minute leak.
For combination vehicles, no more than 10
kPa (4 psi) per minute.
5. Step on and off the brake pedal and check
for the warning light and chime to activate
between 163-193 kPa (64–76 psi).
6. Step on and off the brake pedal and make
sure the tractor protection and parking brake
knobs pop out between 138–310 kPa (20–45
psi)
7. Restart the engine, shift to a lower gear and
gently pull against the service and parking
brakes separately to make sure they hold.
Automatic
transmission fluid:With the engine idling (at normal operating
temperature) and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluidin theMaintenance and
specificationschapter.

Front brakes
Hoses:Checked for cracked, worn or frayed hoses.
Make sure all couplings are secured.
Chambers:Make sure brake chambers are not cracked or
dented and that they are securely mounted.
Slack adjuster:Check for broken, loose or missing parts; the
angle between the push rod and adjuster arm
should be approximately 90 degrees when the
brakes are applied. When pulled by hand, the
push rod should not move more than
approximately 2.5 cm (one inch).
Drum:Make sure there are no cracks, dents or holes
and no loose or missing bolts. Make sure brake
linings are not worn or dangerously thin or
contaminated by lubricant.
Front wheels
Rims:Check for damaged or bent rims. Rims should
not have welding repairs and no rust trails that
indicate it is loose on the wheel.
Lug nuts:Make sure all lug nuts are present and not
loose (look for rust trails around the lug nuts).
There should be no cracks radiating from the
lug bolt holes or distortion of the bolt holes.
Hub oil seal:Check wheel hub oil seal for leaks, and if sight
glass if present, check to see that the oil level
is adequate.
Oil-lubricated front
wheel bearing:If the hubcap has a transparent window, check
for proper lubrication level. If the hubcap does
not have a transparent window, remove the
rubber fill-plug and check for proper level.
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.

Rear springs
Springs:Check for broken or shifted leaves or leaves
that are in contact, or nearly contacting a tire,
rim, brake drum, frame or body components.
Check for missing or broken leaves in the leaf
spring.
Spring mounts:Check for cracked or broken spring hangers,
broken, missing or loose bolts, missing or
damaged bushings, broken, loose or missing
axle mounting parts.
Torsion, shocks:Make sure torsion arm is not cracked, broken
or missing. Check the shock absorber for
cracks or leaks; there should be no missing or
broken mounting bolts or worn bushings.
Rear brakes
Hoses:Checked for cracked, worn or frayed hoses.
Make sure all couplings are secured.
Chambers:Make sure brake chambers are not cracked or
dented and that they are securely mounted.
Slack adjuster:Check for broken, loose or missing parts; the
angle between the push rod and adjuster arm
should be approximately 90 degrees when the
brakes are applied. When pulled by hand, the
push rod should not move more than
approximately 2.5 cm (one inch).
Drum:Make sure there are no cracks, dents or holes
and no loose or missing bolts. Make sure brake
linings are not worn or dangerously thin or
contaminated by lubricant.

Rear wheels
Spacers:Make sure dual wheels are evenly separated
and that tires are not touching one another.
Rims:Check for damaged or bent rims. Rims should
not have welding repairs and no rust trails that
indicate it is loose on the wheel.
Lug nuts:Make sure all lug nuts are present and not
loose (look for rust trails around the lug nuts).
There should be no cracks radiating from the
lug bolt holes or distortion of the bolt holes.
Rear of vehicle
Signal/Brake lights:Make sure both brake lights illuminate when
the brake pedal is applied. Also, make sure
each signal flashes. Make sure that four-way
flashers work properly.
Lights, reflectors:Make sure all lights illuminate and are clean.
Make sure headlights function on both high
and low beams. Make sure reflectors are clean
and unbroken and of proper color (red on
rear, amber elsewhere). Make sure the running
lights are also clean and unbroken. Rear
running lights must be checked separately
from signal, flasher and brake lights.
TRAILER
If you are operating a tractor with a trailer attached, an inspection of the
trailer similar to that of the tractor should be done. Such an inspection
should follow trailer manufacturer recommendation and should include at
a minimum: general condition, landing gear, doors, sides, lights,
reflectors, suspension, brakes, tires and wheels.

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the on position). If your vehicle
is equipped with dual fuel tanks, the
engine will draw fuel from the
passenger-side fuel tank only. With
dual fuel tanks, the vehicle will be
equipped with a fuel transfer pump system that will draw fuel from the
driver-side fuel tank and send fuel to the passenger-side fuel tank. The
passenger-side fuel tank must have fuel in it at all times otherwise the
vehicle may stall and may be difficult to re-start. The fuel gauge reads
the fuel level only from the passenger-side fuel tank.
Air pressure gauge (if
equipped):All vehicles equipped
with air brakes have a dual-pointer
air gauge to indicate the pressure in
each brake circuit. The green
pointer indicates the air pressure in
the primary system and the red
pointer indicates the air pressure in
the secondary system. When the
pressure is too low for normal brake
operation (less than 414 kPa [60
psi]) and the ignition is on:
•a warning buzzer will sound and
•a warning light will illuminate in the instrument cluster
Vehicles equipped with hydraulic brakes and an air compressor have a
single-pointer air gauge.
Note:This system doesnothave a low air pressure warning buzzer or a
low air pressure warning light.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake or suspension system to
operate properly.

If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed; this is normal.
Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.
If the vehicle speed falls below 48 km/h (30 mph) or engine RPM falls
below 1,000 RPM, your speed control will disengage; this is normal.
Pressing RESUME - (instrument panel-mounted controls) or RES
(steering wheel-mounted controls) will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a higher set speed
Instrument panel-mounted
controls:Press and hold SET +. If
the vehicle is moving, this will
increase vehicle speed; if the vehicle
is stationary, this will increase
engine RPM. Release the control
when the desired vehicle
speed/engine RPM is reached.
Press and release SET + to operate the tap-up function. Each press will
increase the set speed by 1.6 km/h (1 mph) or engine RPM in idle mode.
Steering wheel-mounted
controls:Press and hold SET
ACCEL. Release SET ACCEL when
the desired vehicle speed is
reached. SET ACCEL can also be
pressed and released to operate the
tap-up function which will increase
vehicle speed in increments of 1.6
km/h (1 mph).
You can accelerate with the accelerator pedal at any time during speed
control usage. Releasing the accelerator pedal will return your vehicle to
the previously programmed speed.

2. To unfasten, push the release
button and remove the tongue from
the buckle.
The front and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front and rear seat passenger
outboard safety belts have vehicle sensitive emergency locking retractors.
Vehicle sensitive retractor
The vehicle sensitive retractor allows free shoulder belt length
adjustment to your movements and locks in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of approximately 8 km/h (5
mph) or more, the combination safety belts will lock to help reduce
forward movement of the driver and passengers.
Front safety belt height adjustment
SuperCab and CrewCab vehicles have safety belt height adjustments for
the driver and front passenger. Adjust the height of the shoulder belt so
the belt rests across the middle of your shoulder.
