The electrical circuits of the vehicle are safeguarded by a combination of fuses, circuit breakers, and fusible links, with two fuse boxes present, One of these modules is located in the engine compartment and the other is located in the cabin, the passenger area. The engine compartment fuse box is located at the left side of the engine compartment on models from 2000 to 2004, while that of the passenger compartment is at the left end of the instrument panel, behind the coin tray for models from 2005 and later, and in front of it for the earlier models. All the fuses are referenced with the corresponding circuit on which the fuse is secured indicated on the fuse cover and some additional spare fuses along with an exclusive removal tool are also present in the fuse box cover. Small fuses with blades on one of the terminal is convenient to be removed and inserted and while testing for power one has to use the light on the terminal end of the fuse check to see if the fuse is blown. To replace a fuse, one has to pull out the bad one then put a new fuse of the similar type and rating since it is unadvisable to use a fuse of a different amperage. Should a substitute fuse blow out again right away, the cause of the problem, which is usually a short circuit resulting from faulty wiring, should be fixed before placing a new fuse. Fusible links protect certain circuits such as the starter circuit which connects the car starter motor to the alternator and to replace the link, you will need to pull the negative terminal of the car battery. Some circuit breakers focus on the protection of certain circuits like those of power windows and heated seats and they may self-reach once an overload occurs. Vintage warning horn is tested by pulling the breaker slightly off its socket to with voltmeter to ensure battery voltage is available at both ends; if it's not, then the breaker requires replacement. Some circuit breakers are of the type that have to be reset by hand.
