How to Jump Start a Car: What to Check Before You Begin
Before attempting to jump start your car, double-check these critical safety points:
- Inspect the battery: Make sure it’s not leaking, damaged, frozen, or heavily corroded. If you’re unsure, call a professional instead of risking damage or injury.
- Clear the area of metal objects and flames: Remove watches, phones, cigarettes, and any tools. You want to avoid sparks outside the engine compartment.
- Remove the key from the ignition: Keep it somewhere safe and memorable during the process.
- Consult your owner’s manual: Different cars might have specific jump-start instructions.
- Confirm battery voltage compatibility: Both vehicles should have batteries with the same voltage, typically 12 volts. Never connect a 6-volt battery to a 12-volt system.

How to Jump Start a Car: Step-by-Step Instructions
1. Prepare Both Vehicles
- Park the cars close but do not let them touch.
- Shift both into park (automatic) or neutral (manual).
- Turn off both engines and engage parking brakes.
- Pop the hoods and locate the batteries.
2. Connect the Jumper Cables in the Correct Order
Your jumper cables will have two red (positive) and two black (negative) clamps. Attach them in this sequence:
- Red clamp to the positive terminal on the dead battery.
- Red clamp to the positive terminal on the donor battery.
- Black clamp to the negative terminal on the donor battery.
- Black clamp to an unpainted metal surface on the dead car away from the battery (such as a bolt or bracket).
3. Start the Donor Vehicle and Charge the Dead Battery
- Start the working car and let it run for 1-2 minutes to transfer power.
- Attempt to start the car with the dead battery.
- Once started, keep it running for another 1-2 minutes to recharge.
4. Disconnect the Jumper Cables in Reverse Order
- Remove the black clamp from the previously dead car.
- Remove the black clamp from the donor car.
- Remove the red clamp from the donor car.
- Finally, remove the red clamp from the revived battery.
5. Drive Your Car to Recharge the Battery
Drive for at least 30 minutes after jump-starting to allow the battery to recharge fully and avoid future stalls.
When to Call a Professional or Replace Your Battery
If your battery dies frequently, it’s likely time for a replacement. Contact your local Elmhurst, IL service technicians to schedule an appointment or order a new battery online. Routine vehicle maintenance helps prevent dead batteries and keeps your car reliable.
