^ Note the following items when servicing the electrical system.
^ Do not alter the wiring or electrical equipment in any way; this may damage the vehicle or cause a fire from short-circuiting a circuit or overloading it.
^ The negative (-) battery cable must be removed first and installed last.
^ Do not replace with fuses exceeding specified capacity.
CAUTION
^ Be sure that the ignition and other switches are off before disconnecting or connecting the battery cables.
Failure to do so may damage the semiconductor components.
^ Secure harnesses with provided clamps to take up slack.
CAUTION
^ Replacing a fuse with one of a larger capacity than designated may damage components or cause a fire.
^ Tape areas of the harness that may rub or bump against sharp edges to protect it from damage.
^ When mounting components, be sure the harness is not caught or damaged.
CAUTION
^ Clamp all harnesses near vibrating components (for example, the engine) to remove slack and to prevent contact resulting from vibration.
^ Do not handle electrical components roughly or drop them.
^ Disconnect heat- sensitive parts (for example, relays and ECU) when performing maintenance (such as welding) where temperatures may exceed 8O°C (176°F).
^ Make sure that the connectors are securely connected when installed.
^ Do not alter the wiring or electrical equipment in any way; this may damage the vehicle or cause a fire from short-circuiting a circuit or overloading it.
Removal Of Battery Cable:
^ The negative (-) battery cable must be removed first and installed last.
Replacing Of Fuses:

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
