FUSES AND RELAYS

Fuses

If electrical components in the

vehicle are not working, a fuse may

have blown. Blown fuses are

identified by a broken wire within

the fuse. Check the appropriate

fuses before replacing any electrical

components.

15

Note: Always replace a fuse with one that has the specified amperage

rating. Using a fuse with a higher amperage rating can cause severe wire

damage and could start a fire.

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.

CHANGING THE TIRES

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 is not recommended and may

compromise the integrity of your tires. The use of tire sealants

may also affect your tire pressure monitoring system (if equipped).
