Electrical System
High Voltage Devices and Wiring
Warning
Exposure to high voltage can cause shock, burns, and even death. The high voltage components in the vehicle can only be serviced by technicians with special training. High voltage components are identified by labels. Do not remove, open, take apart, or modify these components. High voltage cable or wiring has orange covering or labels. Do not probe, tamper with, cut, or modify high voltage cable or wiring.
Electrical System Overload
The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems. Fuses and circuit breakers protect power devices in the vehicle. Replace a bad fuse with a new one of the identical size and rating. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.
Windshield Wipers
If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.
226 Vehicle Care Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.
{ Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.
To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.
Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as possible.
Engine Compartment Fuse Block
The engine compartment fuse block is on the driver side of the engine compartment, near the battery.
Caution
Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
The vehicle may not be equipped with all of the fuses, relays, and features shown.

Instrument Panel Fuse Block
The instrument panel fuse block is in the instrument panel, on the driver side of the vehicle.
To access the fuses on vehicles equipped with a storage bin:
1. Push forward on the top edge of the bin to unlatch it.
2. Press in on the sides of the bin to release it from the instrument panel.
3. Pivot the door downward, allowing it to hang from the instrument panel.
4. To close the bin, swing it upward and push in until closed.
To access the fuses on vehicles not equipped with a storage bin:
1. Pull the lower edge of the cover rearward. The clips on the lower edge will release, and the upper edge will fall away from the instrument panel.
2. To replace the cover, hook the upper edge of the cover on the instrument panel, and swing the lower edge of the cover into place.
3. Press the lower edge of the cover until the clips engage.
The vehicle may not be equipped with all of the fuses, relays, and features shown.
