1-4 General Information
Section 1: General Information
Quality Assurance
Completed unit sign-off: All control items should be inspected with a written sign-off. All labels
should be inspected and signed off, including verification that the information on the labels is
correct. All appropriate systems should be checked for leaks. A road test should be performed to
verify that all systems are operating correctly. All systems and functions that were provided by
Ford should be checked to make sure that they function correctly after the build process.
The modifier’s Process and Quality Assurance Systems should also make sure that appropriate
training is provided to the employees.
Minimum and Maximum Screw Sizes
When installing aftermarket equipment, avoid using fasteners that are too long for the application
or are in an area which might damage vehicle components, including wiring, brake lines, fuel tank
and lines, powertrain components, exhaust system and suspension.
Tires and Loading
Tire Replacement Requirements
WARNING: Only use replacement tires and wheels that are the same size and type
(such as P-metric versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. Use of any tire or wheel not recommended by Ford can affect the safety
and performance of your vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally the use of
non-recommended tires and wheels could cause steering, suspension, axle or transfer
case/power transfer unit failure. If you have questions regarding tire replacement, see an
authorized Ford or Lincoln Mercury dealer.
WARNING: Do not install an offroad, aggressive tread or incorrectly sized tire. Any of
these may cause elevated stress to the steering system. This can cause the power steering
system to overheat and shut off the power assist, which can affect the safety and
performance of your vehicle.
Note: The Escape/Mariner Hybrid vehicle is equipped with a reduced rolling resistance tire
design. The use of a different tire can effect the fuel economy of your vehicle.
Make sure all tires and wheels on the vehicle are of the same size, type, tread design, brand,
load-carrying capacity and speed rating because it can affect the safety and performance of your
vehicle, which could result in an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
