Engine starting (with parking brake applied)
Steering linkage
free playInspect for excessive free play in the steering
linkages. The steering wheel should have less
than 2 inches (5 centimeters) of free play at its
rim.
Full power
hydraulic brake
inspectionPump the brake pedal several times with the
ignition in the off or run position. You can
momentarily hear the motor and pumps
replenishing the accumulators.
Parking brakeVerify the parking brake holds the vehicle by
gently trying to pull forward with the parking
brake applied.
Air brakesVerify operation using the following procedure.
Chock the wheels, if necessary. Push in the
parking brake and, on tractors, push in the
tractor parking brake knob:
1. Verify the air compressor or governor cutout
pressure is approximately 120 psi (827 kPa).
2. Turn off the engine, and then turn the key
back to the on position (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 vehicles and 3 psi
(21 kPa) for combination vehicles.
4. Press and hold the brake pedal with 90 psi
(621 kPa) or more. Make sure there is no more
than a 3–psi (21 kPa) per minute leak for single
vehicles and a 4–psi (28 kPa) per minute leak for
combination vehicles.
5. Pump the brake pedal to deplete the system of
air pressure. The warning light and tone should
turn on at 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 fluidVerify that the fluid level is in the proper
operating range. SeeTransmission fluid check

be no cracks radiating from the lug bolt holes or
distortion of the bolt holes.
Hub oil sealsInspect wheel hub oil seal for leaks and, if sight
glass if present, verify the oil level is adequate.
Oil-lubricated
front wheel

has a transparent window. If the hubcap does not
have a transparent window, remove the rubber
fill-plug and inspect for proper level.
Fuel area

Trailer
If you are pulling a trailer, perform an inspection of the trailer similar to
that of the tractor. The inspection should follow trailer manufacturer
recommendations 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
WARNING: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.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

Using Safety Belts During Pregnancy
WARNING:Always ride and drive with your seatback upright
and the safety belt properly fastened. The lap portion of the
safety belt should fit snug and be positioned low across the hips. The
shoulder portion of the safety belt should be positioned across the
chest. Pregnant women should also follow this practice. See the
following figure.
Pregnant women should always
wear their safety belts. The lap belt
portion of a combination lap and
shoulder belt should be positioned
low across the hips below the belly
and worn as tight as comfort will
allow. The shoulder belt should be
positioned to cross the middle of
the shoulder and the center of the
chest.
Safety Belt Locking Modes
WARNING:After any vehicle crash, all safety belts should be
checked for proper function.
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front and rear center seat
safety belt have the first locking mode described below only. All outboard
passenger and outboard rear safety belts have both types of locking
modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of about 5 mph (8 km/h) or
more, the combination safety belts will lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.

Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents you from moving the gearshift lever from position
Pwhen the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of positionPwith the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or your vehicle’s brake lamps are not operating properly. See
theFuseschapter.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
