1-4 General Information
Section 1: General Information
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 the low-voltage wiring, the
high-voltage system including the high-voltage traction battery (HVTB) and the (orange)
high-voltage wiring/cables, brake lines, fuel tank and lines, powertrain components, exhaust
system or 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 the loss of
vehicle control, vehicle rollover, personal injury or death. Additionally, the use of
non-recommended tires and wheels could cause steering or suspension failure. If you have
questions regarding tire replacement, see an authorized Ford or Lincoln dealer.
NOTICE: Do not install an off road, 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 Fusion Hybrid and MKZ Hybrid vehicles are equipped with a reduced rolling resistance
tire design. The use of a different tire can affect the fuel economy of the 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.
Using Snow Tires and Traction Devices
Note: Snow tires must be the same size and grade as originally equipped on your vehicle.
The tires on your vehicle have all-weather tread to provide traction in the rain and snow; however,
in some climates, using snow tires or traction devices may be necessary.
Follow these guidelines when using snow tires and traction devices:
• SAE Class ‘‘S’’ cables should ONLY be used on the vehicle front tires.
• Install cables or chains securely, verifying that the cables or chains do not touch any wiring,
brake lines or fuel lines.
