How to Jump Start a Honda Passport

1. Turn off power to electric devices such as the audio system and lights.
2. Set the power modes of your vehicle and the assisting vehicle to OFF.
3. Connect the first jumper cable to the terminal of your vehicle's 12-volt battery.
4. Connect the other end of that cable to the terminal of the assisting vehicle's battery.
5. Connect the second jumper cable to the other terminal of the assisting vehicle's battery.
6. Connect the other end of the second cable to your vehicle's ground bolt.
7. Start the assisting vehicle's engine and raise its RPM slightly, then start your vehicle's engine.

• Use a 12-volt booster battery only; if using a charger, select a voltage lower than 15-volt.
• After the engine starts, remove cables in order: your ground, booster battery end, your 12-volt battery terminal, other booster end.
• Keep sparks, open flames, and smoking materials away from the battery, which can explode.
