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
Batterysection of theMaintenance and Specificationschapter.
The high-current fuses are coded as follows:

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:The tire pressure monitoring system (TPMS) 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.
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. Replace the spare
tire with a road tire as soon as possible.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.
Refer toTire Pressure Monitoring System (TPMS)in the
Tires, Wheels and Loadingchapter for important information. If
the tire pressure monitor sensor becomes damaged, it will no longer
function.
