■Operating conditions
The system will only operate if all of the following conditions are met:
●The shift position is in P.
●The power switch is off.
*
●All doors are closed.
●The hood is closed.
*: The Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 10 minutes have passed since operation began
●Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low
●The outside temperature is extremely low
●When the hybrid system is cool (for example, after being left for a long time
in low temperatures)
■Windshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
■Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.
■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The emergency flashers flash to indicate that the doors have been locked
or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)

A charging message will be displayed on the multi-information display. Differ-
ent messages will be displayed depending on when the Remote Air Condi-
tioning System was started (after charging or during charging).

tem, the electric fan may spin and an operating noise may be heard.
However, this does not indicate a malfunction.
●The Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery
becomes low.
●The headlights, windshield wiper, combination meter, etc. will not operate
while the Remote Air Conditioning System is operating.

WARNING
■Precautions for the Remote Air Conditioning System
● Do not use the system if people are in the vehicle.
Even when the system is in use, the internal temperature may still reach a
high or low level due to features such as the automatic shut-off. Children
and pets left inside the vehicle may suffer heatstroke dehydration or hypo-
thermia, or could result in death or serious injury.
● Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● Do not operate “A/C” if the hood is open. The air conditioning may operate
unintentionally and objects may be drawn into the electrical cooling fan.
NOTICE
■ To prevent the hybrid battery (traction battery) from being discharged
through incorrect operation
Use “A/C” only when necessary.

5847-2. Maintenance
PRIUS PHV_OM_OM47C99E_(EE)
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use
genuine Toyota parts in repairing any difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers or repairers for
non-warranty repairs and services, as members of the Toyota network will be
able to expertly assist you with any difficulties you may encounter.
Your Toyota retailer or Toyota authorized repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal (P. 673, 718)
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.
