AVALON_HV_U (OM41457U)
■Discharge headlights (if equipped)
If voltage to the discharge bulbs is insufficient, the bulbs may not come on, or
may go out temporarily. The discharge bulbs will come on when normal
power is restored.
■ LED light bulbs
The daytime running lights (vehicles with discharge headlights), stop/tail
lights, high mounted stoplight and outer foot lights each consist of a number
of LEDs. If any of the LEDs burn out, take your vehicle to your Toyota dealer
to have the light replaced.
■ Condensation build-up on the inside of the lens
Temporary condensation build-up on the inside of the lens does not indicate a
malfunction. Contact your Toyota dealer for more information in the following
situations:
●Large drops of water have built up on the inside of the lens.
● Water has built up inside the lens.

Maintenance and care
AVALON_HV_U (OM41457U)
CAUTION
■Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure 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.
●Vehicles with discharge headlights:
While the low beam headlights are
turned on, and for a short time after
they have been turned off, metal com-
ponents at the rear of the headlight
assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they
have cooled down.

CAUTION
■Discharge headlights (if equipped)
● Contact your Toyota dealer before replacing the discharge headlights
(including light bulbs).
● Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 30000 V will be discharged and could result
in death or serious injury by electric shock.
● Do not attempt to take apart or repair the headlight bulbs, connectors,
power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■ To prevent damage or fire
● Make sure bulbs are fully seated and locked.
● Check the wattage of the bulb before installing to prevent heat damage.

When trouble arises
AVALON_HV_U (OM41457U)
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the 12-volt
battery and an y moving parts, as s hown in the illustration.
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that le vel for approximately 5 minutes 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 t he second vehicle and start the
hybrid system of your vehicle by turning the power switch to ON
mode.
Make sure the “READY” indicato r comes on. If the indicator does
not come on, contact your Toyota dealer.
Once the hybrid system has start ed, 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
Toyota dealer as soon as possible.
■ Starting the hybrid system when th e 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.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
