PRIUS c_U (OM52G95U)■
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
●Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) under t\
he
rear seats when the hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), under the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent on the side of the
lower part of the rear left seat.
■ Vehicle Proximity Notification System
In the following cases, the Vehicle Proximity Notification System sound may
be difficult for pedestrians, people ridi ng bicycles or other people and vehicles
in the surrounding area to hear:
● When there is a lot of noise in the vicinity
● When it is raining or during strong winds
● When in the area surrounding the rear of the vehicle, rather than in front of
the vehicle
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

NOTICE
■Hybrid battery (traction battery) air intake vent
● Do not place objects that will block the air intake vent. When the air intake
vent is blocked, the battery operations will be restricted and cause a
decline in fuel consumption.
● Clean the air intake vent regularly to prevent the hybrid battery (traction
battery) from overheating.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. For information regarding filter cleaning or
replacement, contact your Toyota dealer.
● If “MAINTENANCE REQUIRED FOR TRACTION BATTERY COOLING
PARTS SEE OWNER’S MANUAL” is shown on the multi-information dis-
play, the air intake vent and filter may be clogged. Refer to P. 406 for infor-
mation on how to clean the air intake vent.

1-3. Theft deterrent system
Vehicles without a smart key sys-
tem: The indicator light flashes
after the key has been removed
from the power switch to indicate
that the system is operating.
The indicator light stops flashing
after the registered key has been
inserted into the power switch to
indicate that the system has been
canceled.
Vehicles with a smart key system: The indicator light flashes after the
power switch has been turned off to indicate that the system is operat-
ing.
The indicator light stops flashing after the power switch has been turned to
ACCESSORY or ON mode to indicate that the system has been canceled.
■ System maintenance
The vehicle has a maintenance-free type immobilizer system.
■ Conditions affecting operation
Depending on the surrounding environment and conditions, the immobilizer
system may not operate properly. This may prevent the hybrid system from
starting. ( →P. 141)
Immobilizer system∗
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system from starting if a key has not been previously
registered in the vehi cle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.

chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle

t of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle's paint.
● In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent the vehicle from being cleaned properly or
result in damage to the rear spoiler.
■ High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of
the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.

If the door handle becomes wet while the electronic key is within the ef\
fective
range, the door may lock and unlock repeatedly. In that case, follow the fol-
lowing correction procedures to wash the vehicle:
●Place the electronic key in a location 6 ft. (2 m) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)
● Set the electronic key to battery-saving mode to disable the smart key sys-
tem. ( →P. 140)

Installation area of front sensor on windshield: →P. 228
■ 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.
NOTICE
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
● Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
● If the paint is chipped or scratched, have it repaired immediately.

area directly with a high pressure washer. Shock applied from high pres-
sure water may cause the device to not operate normally.
● Do not bring the nozzle tip close to boots (rubber or resin manufactured
cover), connectors or the following parts. The parts may be damaged if
they come into contact with high-pressure water.
Do not pull, push, or hold onto either roof molding or attach anything to
them, as the roof molding may be partially removed and water may leak
into the vehicle.
■ Roof molding (if equipped)
