Jump Starting: Service and Repair
NOTICE: Hybrid vehicles cannot be push started.
Jump starting
If the auxiliary battery is discharged the hybrid system can be started by jump starting. Depending on the the vehicle condition, the engine may not start.
To avoid serious personal injury and damage to your vehicle which might result from battery explosion, acid burns electrical burns, or damaged electronic components, these instructions must followed precisely.
NOTICE
If the auxiliary battery is discharged, you cannot access the auxiliary battery in the luggage compartment because the back door cannot be opened. Use the exclusive jump starting terminal in the engine compartment.
If the auxiliary battery is discharged with the transaxle in "P", your vehicle cannot be moved unless the front wheels are raised. This is because the front wheels are locked by means of the parking lock mechanism.
If you are unsure about how to follow this procedure, we strongly recommend that you seek the help of a competent qualified technician or towing service.
CAUTION
Auxiliary battery and booster battery contain sulfuric acid which is poisonous and corrosive. Wear protective safety glasses when jump starting, and avoid spilling acid on your skin, clothing, or vehicle.
If you should accidentally get acid on yourself or in your eyes, remove any contaminated clothing and flush the affected area with water immediately. Then get immediate medical attention. If possible, continue to apply water with a sponge or cloth while en route to the medical office.
The gas normally produced by a battery will explode if a flame or spark is brought near. Use only standardized jumper cables and do not smoke or light a match while jump starting.
Warning: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
The battery used for boosting must be 12V.
Do not jump start unless you are sure the booster battery is correct.
After jump starting procedure, the hybrid system may not start by pushing the "POWER" switch. In that case push it once again. If the "READY" light does not come on contact your Toyota dealer.
JUMP STARTING PROCEDURE
1. Apply the parking brake and turn off the headlight switch and interior light.
2. Turn off the hybrid system and remove the key if inserted.
3. Open the hood and fuse block cover shown in the above illustration.
4. Open the exclusive jump starting terminal cover.
5. If the booster battery is installed in another vehicle, make sure the vehicles are not touching. Turn off all unnecessary lights and accessories. When boosting, use the battery of matching or higher quality. Any other battery may be difficult to jump start with. If jump starting is difficult, charge the battery for several minutes.
6. If required, remove all the vent plugs from the booster batteries. Lay a cloth over the open vents on the batteries. (This helps reduce the explosion hazard, personal injuries and burns.)
7. If the engine in the vehicle with the booster battery is not running, start it and let it run for a few minutes. During jump starting, run the engine at about 2000 rpm with the accelerator pedal lightly depressed.
8. Connect the jumper cables in the order a, b, c, d.
a. Connect the clamp of the positive (red) jumper cable to the exclusive jump starting terminal.
b. Connect the clamp at the other end of the positive (red) jumper cable to the positive (+) terminal on the booster battery.
c. Connect the clamp of the negative (black) jumper cable to the negative (-) terminal on the booster battery.
d. Connect the clamp at the other end of the negative (black) jumper cable to a solid, stationary, unpainted, metallic point of the vehicle with the discharged battery. The recommended connecting point is shown above.
CAUTION
When making the connections, to avoid serious injury, do not lean over the battery or accidentally let the jumper cable, or clamps touch anything except the correct battery terminals or the ground.
9. Charge the discharged battery with the jumper cables connected for approximately 5 minutes. At this time, run the engine in the vehicle with the booster battery at about 2000 rpm with the accelerator pedal lightly depressed.
10. Start the hybrid system. Make sure the "READY" light is on. If the hybrid vehicle battery warning light comes on in the multi information display, the hybrid vehicle battery is also discharged. Contact your Toyota dealer.
11. Carefully disconnect the cables in the exact reverse order: the negative cable and then the positive cable.
12. Carefully dispose of the battery cover cloths. They may now contain sulfuric acid.
13. If removed, replace all the battery vent plugs. If the cause of your auxiliary battery discharging is not apparent (for example, lights left on), you should have it checked at your Toyota dealer
If the first start attempt is not successful:
Check that the clamps on the jumper cables are tight. Recharge the discharged battery with the jumper cables connected for several minutes and restart your hybrid system in the normal way. If another attempt is not successful, the battery may be depleted. Have it checked at your Toyota dealer.
