Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Service Precautions: Notes
The following precautionary measures must be taken before disconnecting or total discharge of battery or serious electrical damage can occur:
- To avoid triggering siren, on vehicles equipped with an additional alarm siren, battery must be disconnected with ignition switch turned to ON position.
- All loads must be switched off and ignition key removed from ignition switch.
- Never disconnect battery with engine running.
- Ensure battery is securely connected before starting.
- Do not use a boost charger to start engine.
- Never start engine, unless battery is securely connected.
- Battery terminals should be connected without force, to prevent damage to battery housing.
- When jump starting, use jumper cables with overvoltage protection.
- Always disconnect battery before performing any welding.
- After installation, ensure battery is seated correctly. Other dangers exist with a loose battery such as: reduced service life due to vibration, damage to grid plates of battery, damage to battery housing from mounting elements (possible acid leak), or inadequate crash safety.
