Fuse / Relay Center

WARNING

Do not arrange fuses improperly or use replacement fuses with improper amperage values. This could lead to electrical overload, which can result in severe injury or death.

If the engine stops or will not start, if the power steering stops working (if equipped), or if you experience other electrical failures, a fuse may need replacement. Locate and correct any short circuits that may have caused the blown fuse, then replace the fuse.

There are two fuse/relay centers accessible on the vehicle. The primary fuse center

is beneath the armrest and can be accessed by removing the bed of the armrest storage compartment.
