Engine starting (parking brake applied)
Parking brake:Check that the parking brake will hold the
vehicle by gently trying to pull forward with
the 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 parking brake knob):
1. Check the air compressor or governor
cut-out pressure (approximately 120 psi
[827 kPa]).
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 2 psi (14 kPa) for single vehicle and
3 psi (21 kPa) for combination vehicles.
4. Depress and hold the brake pedal with
90 psi (621 kPa) or more and make sure there
is no more than a 3 psi (21 kPa) per minute
leak. For combination vehicles, no more than
4 psi (28 kPa) per minute.
5. Pump the brake pedal to deplete the system
air pressure. The warning light and chime
should activate 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.
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:Check 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° when the brakes
are applied. When pulled by hand, the push
rod should not move more than approximately
one inch (2.5 cm).
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.

Tractor - coupling system
Kingpin/Apron:Make sure kingpin is not bent or worn. Also
make sure that the apron lies flat on the fifth
wheel skid plate and that the visible part of
the apron is not bent, worn, cracked or
broken.
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° when the brakes
are applied. When pulled by hand, the push
rod should not move more than approximately
one inch (2.5 cm).

Rear brakes
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.
Trailer
If you are pulling a trailer, 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, wheels, cargo placement, stability and tie-downs.
Transmission
If your vehicle is equipped with an automatic transmission, regularly
check the transmission’s neutral start switch. The engine should only
start in the N (Neutral) or P (Park) positions.
If the unit starts in gear and/or the neutral start switch is not
functioning correctly, the vehicle may inadvertently move which
could result in property damage, personal injury or death.
Check the transmission fluid level and shift linkage for proper operation.

Air pressure gauge: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
60 psi [414 kPa]) and the ignition is
on:
•a warning buzzer will sound and
•a warning light will illuminate in the instrument cluster
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.
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.

To turn speed control off
Press OFF or turn off the ignition.
Once speed control is switched off,
the previously programmed engine
RPM will be erased.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
To set a speed
Press SET +. If the vehicle is
moving, this will set the vehicle
speed. If the vehicle is stationary,
this will set the vehicle idle RPM.
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 30 mph (48 km/h) or engine RPM falls
below 1,000 RPM, your speed control will disengage; this is normal.
Pressing RESUME - will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.

Shorten and fasten the belt when
not in use.
Vehicle sensitive mode
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 5 mph
(8 km/h) 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 Crew Cab vehicles have safety belt height adjustments for
the driver and front outboard passenger. Adjust the height of the
shoulder belt so the belt rests across the middle of your shoulder.

get out of the vehicle and visually check the intended path is clear;
back-up slowly as to allow others time to move, if necessary.
If an electrical back-up alarm is installed, it should be connected to the
back-up lamp circuit.
Parking your vehicle
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires will act against the curb to stop the vehicle. The front
wheels will be more effective at stopping a rolling vehicle than the rear
wheels.
When parking your vehicle, do not leave the transmission in
gear; if the key is in the ON position and the vehicle rolls, the
engine could start. Failure to follow these instructions could result in
an unattended vehicle moving, possibly causing personal injury or
property damage.
Driving through water
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine, drive axles or the transmission
(through the breather ports).
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.
ENGINE AUTOMATIC SHUTDOWN WARNING LIGHT OR CHIME (IF
EQUIPPED)
Your vehicle may be equipped with an automatic shutdown feature that
stops the engine in the event of high coolant temperature, low engine oil
pressure, high diesel particulate filter soot loading or low engine coolant
level. A warning light in the instrument cluster and a warning chime will
indicate high engine coolant temperature, low engine oil pressure or the
need to have the diesel particulate filter cleaned or serviced. If the
engine coolant temperature becomes too high, engine oil pressure too
low or the diesel particulate filter too restricted, the engine will
automatically shut down.

If the engine shuts down, it can be restarted and operated for 30
seconds at a time or until the problem is corrected. Do not attempt to
use this restarting feature to drive the vehicle very far as serious engine
damage could result.
In the event of engine shutdown, make sure the vehicle is safely
off the road and the problem is remedied prior to returning to
the road. Failure to remove the vehicle from the road could result in
an accident, causing serious injury or death.
GENERAL BRAKE INFORMATION
All standard equipment brakes are designed to be self-adjusting.
Automatic adjustment, when required, occurs whenever the brakes are
applied and released during forward or reverse operation. Refer to the
Scheduled Maintenance Guidechapter for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
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.
