Use a multimeter to measure the battery voltage; a healthy battery should read around 12.6 volts or higher.
3
Inspect fuses related to the starting and electrical systems for any blown fuses.
4
Attempt to jump-start the vehicle using jumper cables and a working vehicle.
5
If jump-starting is successful, monitor the battery voltage after disconnecting the jumper cables to see if it holds charge.

Solution

Solution

1. Preparation

Gather necessary tools and materials.
Ensure safety gear is used, including gloves and goggles.
Park both vehicles close enough to connect the jumper cables without strain.

2. Jump-Starting the Battery

Connect Jumper Cables:
- Connect one end of the red jumper cable to the positive terminal (+) of the dead battery.
- Connect the other end of the red jumper cable to the positive terminal (+) of the working battery.
- Connect one end of the black jumper cable to the negative terminal (-) of the working battery.
- Connect the other end of the black jumper cable to an unpainted metal surface on the engine block of the dead vehicle (not to the negative terminal of the dead battery).
Start the Working Vehicle:
- Start the engine of the working vehicle and let it run for 2-5 minutes to allow the dead battery to charge.
Start the Dead Vehicle:
- Try to start the Toyota Camry. If it starts, let it run for at least 10-15 minutes to charge the battery further.

3. Inspect and Replace Battery (if necessary)

Inspect Battery:
- If the vehicle does not start after jump-starting, disconnect the jumper cables and inspect the battery for physical damage or swelling.
Battery Replacement:
- If the battery is confirmed dead, remove it by loosening the negative terminal (-) first, then the positive terminal (+).
- Remove the battery hold-down clamp and lift the battery out of the tray.
- Place the new battery into the tray, securing it with the hold-down clamp.
- Connect the positive terminal (+) first, then the negative terminal (-).
