■Headlight control sensor (if equipped)
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30
seconds after a door is opened and closed if the “POWER” switch is
turned to ACCESSORY mode or turned off. (The lights turn off immedi-
ately if on the key is pressed after all the doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if
the “POWER” switch is turned to ACCESSORY mode or turned off and
the driver’s door is opened.
To turn the lights on again, turn the “POWER” switch to ON mode, or turn the
light switch off once and then back to or .
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.

PRIUS PHV_OM_OM47818U_(U)
■When using a car wash
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■While charging
Do not wash the vehicle.
Doing so may cause the electrical components to malfunction or catch fire
and also you may get an electric shock that may result in death or serious
injury.
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.

Maintenance and care
■After charging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
●Start the hybrid system with the “POW ER” swi tc h in ACC ESSORY mode.
The hybrid system may not start with the “POWER” switch turned off.
However, the hybrid system will operate normally from the second
attempt.
●The “POWER” switch mode is recorded by the vehicle. If the 12-volt bat-
tery is reconnected, the vehicle will return the “POWER” switch mode to
the status it was in before the 12-volt battery was disconnected. Make
sure to turn off the power before disconnect the 12-volt battery. Take
extra care when connecting the 12-volt battery if the “POWER” switch
mode prior to discharge is unknown.
●Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.
