A jump start, also called a boost, is a method of starting a vehicle with a discharged or dead battery. A temporary connection is made to the battery of another vehicle, or to some other external power source.
Jump starting can be dangerous if done incorrectly. Therefore, to avoid harm to yourself or damage to your vehicle or battery, follow the jump starting procedures. If in doubt, we strongly recommend that you have a competent technician or towing service jump start your vehicle.
If the vehicle battery is discharged
The following procedures may be used to start the engine if the vehicle’s battery is discharged. You can also call your Toyota dealer or a qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehicle with a 12-volt battery, you can jump start your vehicle by following the steps below.
- Vehicles with an alarm: Confirm that the electronic key (vehicles with a smart key system) or key (vehicles without a smart key system) is being carried.
When connecting the jumper (or booster) cables, depending on the situation, the alarm may activate and doors locked.
- Open the hood.
- Vehicles with 3.5 L V6 (2GRFKS) engine: Remove the engine cover.
Make sure to pull the engine cover straight up when removing it.
- Connect the jumper cables according to the following procedure:
- Connect a positive jumper cable clamp to the positive (+) battery terminal on your vehicle.
- Connect the clamp on the other end of the positive cable to the positive (+) battery terminal on the second vehicle.
- Connect a negative cable clamp to the negative (-) battery terminal on the second vehicle.
- Connect the clamp at the other end of the negative cable to a solid, stationary, unpainted metallic point away from the battery and any moving parts, as shown in the illustration.
- Start the engine of the second vehicle. Increase the engine speed slightly and maintain at that level for approximately 5 minutes to recharge the battery of your vehicle.
- Vehicles with a smart key system: Open and close any of the doors of your vehicle with the engine switch off.
- Vehicles without a smart key system:
Maintain the engine speed of the second vehicle and turn the engine switch to the “ON” position, then start the vehicle’s engine.
Vehicles with a smart key system:
Maintain the engine speed of the second vehicle and turn the engine switch to IGNITION ON mode, then start the vehicle’s engine.
- Once the vehicle’s engine has started, remove the jumper cables in the exact reverse order from which they were connected.
