Tire inflation information
All tires with Steel Carcass Plies (if equipped):
This type of tire utilizes steel cords in the sidewalls. As such, they
cannot be treated like normal light truck tires. Tire service, including
adjusting the air pressure, must be performed by personnel trained,
supervised and equipped according to Federal Occupational Safety and
Health Administration (OSHA) regulations. For example, during any
procedure involving tire inflation, the technician or individual must
utilize a remote inflation device, and ensure that all persons are clear of
the trajectory area.
WARNINGAn inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and
property.

FACTORY AUTHORIZED SYSTEMS CHECKS
In the event that your vehicle experiences a component related concern,
please contact your Ford dealership. The Ford Motor Company Trained
Technicians who work at Ford dealerships are specifically trained to
understand your vehicle.
A proper repair begins with a thorough system check. A Factory
Authorized Systems Check can ONLY be found at a Ford dealership. In
some circumstances, the technician may need to request your
authorization to perform additional operations to determine the final
diagnosis. The technician’s goal is to ensure that your vehicle is fixed
right the first time, at the best value to you.
The following list represents several of the Factory Authorized Systems
Checks available at a participating Ford dealers:
•Air Conditioning
•Check Engine Light
•All Wheel Drive and4X4
•Automatic Transmission
•Engine Cooling and Cabin Heating
•Steering and Suspension
•Charge/Start/Battery
•Wheel Alignment
•Anti-Lock Brake System
EMISSIONS CONTROL SYSTEM
To ensure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and mileage/km intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
