Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, always replace the cover to
the Power Distribution Box before reconnecting the battery or
refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Battery section of the Maintenance and Specifications chapter.

Relays
An auxiliary relay box is located in the left-hand front side of the engine
compartment. This box contains relays for the Electronic Shift On the
Fly (ESOF) system. Please see your authorized dealer for
troubleshooting or service of these relays.
CHANGING A FLAT TIRE
If you get a flat tire while driving:
• do not brake heavily.
• gradually decrease the vehicle’s speed.
• hold the steering wheel firmly.
• slowly move to a safe place on the side of the road.
The use of tire sealants may damage your tires.
Dissimilar spare tire/wheel information
Failure to follow these guidelines could result in an increased
risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire/wheel, then it is intended for
temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.
