Engine starting (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
knobs pop out at 20 psi (138 kPa) or higher.
Parking brake:Check that the parking brake will hold the
vehicle by gently trying to pull forward with
the parking brake applied.
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 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.
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 1 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.

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.

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
60 psi [414 kPa]) 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 30 mph (48 km/h) 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 mph (1.6 km/h) 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
mph (1.6 km/h).
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 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
Regular cab, 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.

Backing up
To reduce the risk of the possibility of personal injury while
backing the vehicle, always be sure your vehicle’s path is clear.
Before backing your vehicle, be sure you can do so safely. If anything
behind the cab limits your view, do not rely on mirrors alone to assure
that your intended path is clear. If other people are in the vicinity, have
someone standing well behind your vehicle and outside of your intended
path (visible through an exterior mirror) guide you as you back up.
Although OSHA or some governmental regulations may require the use
of an electrical or mechanical back-up alarm to warn bystanders, such an
alarm does not assure that the intended path is clear. When in doubt, 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 transmisison
(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.

HYDRAULIC BRAKES (IF EQUIPPED)
Your service brakes are self-adjusting. Refer to theGeneral
Maintenance Informationfor 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.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Note:Normally, choose the same gear to descend the hill that you would
use to ascend the hill.
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.
Hydraulic brake booster system (Hydromax)
The Hydromax systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The Hydromax booster receives backup 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 may be heard by the driver, but this is
a normal characteristic of the system.
