current fuses.
WARNING: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
Batterysection of theMaintenance and Specificationschapter.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
toTire pressure monitoring system (TPMS)in theTires, Wheels and
Loadingchapter.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
