CAUTION
■Replacing light bulbs
● Turn off the headlights. Do not attempt to replace the bulb immediately
after turning off the headlights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion.
If the bulb is scratched or dropped it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failing to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not take apart or repair the low beam discharge headlight bulbs, con-
nectors, power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■ High-intensity discharge (HID) headlights
● Contact your Toyota dealer before replacing high-intensity discharge
headlights (including light bulbs).
● Do not touch the high-intensity discharge headlight’s high voltage socket
when the headlights are turned on. An extremely high voltage of 20000V
will be discharged and could result in death or serious injury by electric
shock.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.

■
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 hybrid system.
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 hybrid syst em has started, remove the
jumper cables in the exact reverse order in which they were
connected.
Once the hybrid system starts, have the vehicle checked at your
Toyota dealer as soon as possible.STEP4
