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.

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.

GENERAL INFORMATION
See the following sections for directions on how to properly use safety
restraints for children.
WARNING:Always make sure your child is secured properly in a
device that is appropriate for their height, age and weight. Child
safety restraints must be bought separately from your vehicle. Failure
to follow these instructions and guidelines may result in an increased
risk of serious injury or death to your child.
WARNING:All children are shaped differently. The
recommendations for safety restraints are based on probable
child height, age and weight thresholds from NHTSA and other safety
organizations, or are the minimum requirements of law. Ford
recommends checking with a NHTSA Certified Child Passenger Safety
Technician (CPST) and consulting your pediatrician to make sure your
child seat is appropriate for your child, and is compatible with and
properly installed in your vehicle. To locate a child seat fitting station
and CPST, contact the NHTSA toll free at 1-888-327-4236 or on the
internet at http://www.nhtsa.dot.gov. In Canada, check with your local
St. John Ambulance office for referral to a CPST or for further
information, contact your provincial ministry of transportation, or locate
your local St. John Ambulance office by searching for St. John
Ambulance on the internet, or Transport Canada at 1–800–333–0371
(http://www.tc.gc.ca). Failure to properly restrain children in safety
seats made especially for their height, age, and weight may result in an
increased risk of serious injury or death to your child.
