and/or tail lights are on when the engine switch is turned to the “LOCK” posi-
tion (vehicles without a smart key system) or when the “ENGINE START
STOP” switch is turned off (vehicles with a smart key system) the battery
saving function will operate and automatically turn off all the lights after
approximately 20 minutes.
When the engine switch is turned to the “ON” position (vehicles without a
smart key system) or when the “ENGINE START STOP” switch is turned to
IGNITION ON mode (vehicles with a smart key system), the battery-saving
function will be disabled.

celed once and then reactivated. All the lights will turn off automatically 20
minutes after the battery-saving function has been reactivated:
●When the headlight switch is operated
● When a door is opened or closed

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 serious injury or death by electric shock.
● Do not attempt to take apart or repair the low beam discharge headlight
bulbs, connectors, power supply circuits, or related components.
Doing so could result in electric shock and serious injury or death.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
●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.Metal
