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.
WARNING: Always disconnect the battery before servicing high
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
Battery section of the Maintenance and Specifications chapter.

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
to Tire pressure monitoring system (TPMS) in the Tires, Wheels and
Loading chapter. Replace the spare tire with a road tire as soon as
possible. During repairing or replacing of the flat tire, have the
authorized dealer inspect the TPMS sensor for damage. Roadside Emergencies
