Ensure the vehicle is in a safe location with the ignition turned off.

2. Battery Inspection and Replacement

Inspect Battery:
- Use a multimeter to measure battery voltage.
- If the voltage is below 12.4 volts, proceed to jump-start or replace the battery.
Clean Battery Terminals:
- Disconnect the negative terminal first, then the positive terminal.
- Clean any corrosion from terminals and cable connectors using a wire brush.
- Reconnect terminals, ensuring they are tight.
Replace Battery (if necessary):
- Remove the old battery by unbolting it from the bracket.
- Install the new battery, connecting positive first, then negative.
- Ensure all connections are secure.

3. Starter Motor Inspection

Access Starter Motor:
- Raise the vehicle safely using jack stands and remove the undertray if applicable.
Test Starter Motor:
