5-2. Steps to take in an emergency
■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
● The power back door must be initialized. (P. 665)
● The hybrid system may not start. (P. 493)
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the exclusive jump
starting terminal and any moving parts, as shown in the illustration.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain that level for approximately 5 min-
utes to recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the
“POWER” switch off.
Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the “POWER” switch
to ON mode.
Make sure the “READY” indicator comes on. If the indicator
does not comes on, contact your Lexus dealer.
Once the hybrid system has started, remove the jumper cables
in the exact reverse order from which they were connected.
Once the hybrid system starts, have the vehicle inspected at your
Lexus dealer as soon as possible.
