Starting the hybrid system when the battery is discharged
The hybrid system cannot be started by push-starting.
■ Avoiding a discharged 12 volt battery
● Turn off the headlights and the audio system while the hybrid system is
turned off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately
five minutes to recharge the 12 volt battery of your vehicle.
Open and close any of the doors with the “POWER” switch
OFF.
Maintain the engine speed on the second vehicle and turn
the “POWER” switch to the ON mode, then start the vehi-
cle’s engine.
Make sure the “READY” light comes on. If the “READY”
light will not come on and the hybrid system will not start
after you recharge the battery, do the following procedure.
Turn the hybrid system off. Open and close the driver’s
door. Then push the “POWER” switch briefly and firmly. If
the light does not come on, contact your Toyota dealer.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Toyota
dealer as soon as possible.STEP4
