FUSES

WARNING

- When replacing a blown fuse, always use an appropriate replacement fuse with the same amp rating as the original fuse. Never replace a fuse with another fuse of higher amp rating. Never replace a blown fuse with metal wires or any other material. Do not place a fuse inside a circuit breaker cavity or vice versa. Failure to use proper fuses may result in serious personal injury, fire and/or property damage.
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- If the replaced fuse blows again, contact an authorized dealer.
- If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, transmission system) or steering system blows, contact an  authorized dealer.

CAUTION
If it is necessary to wash the engine compartment, take care not to directly hit the fuse box, and the windshield wiper motors with water.

The fuses protect electrical systems against excessive current.
When a device does not work, you must check the fuse element inside the blade fuse for a  break/melt.
Also, please be aware that when using power outlets for extended periods of time with the  engine off may result in vehicle battery discharge.

 

Blade Fuse

 

1 — Fuse Element
2 — Blade Fuse with a good/functional fuse element
3 — Blade fuse with a bad/not functional fuse element (blown fuse)

CAUTION!
- When installing the power distribution center cover, it is important to ensure the cover is  properly positioned and fully latched. Failure to do so may allow water to get into the power distribution center and possibly result in an electrical system failure.
- When replacing a blown fuse, it is important to use only a fuse having the correct amperage  rating. The use of a fuse with a rating other than indicated may result in a dangerous  electrical  system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.
