701-4. Hybrid system
COROLLA HV_U
■After the 12-volt battery has dis-
charged or when the terminal
has been removed and installed
during exchange, etc.
The gasoline engine may not stop
even if the vehicle is being driven by
the hybrid battery (traction battery).
If this continues for a few days, con-
tact your Toyota dealer.
■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” indi-
cator 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 malfunc-
tion:
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
under the 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 system is started
or stopped.
●Sounds from the hybrid system
may be heard when the trunk lid is
open.
●Sounds may be heard from the
transmission when the gasoline
engine starts or stops, when driv-
ing 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 dep ressed 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 right
seat.
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
■Customization
Some functions can be customized.
(  P.516)
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Vehicle proximity notification
system
In the following ca ses, the vehicle
proximity notification system may be
difficult for surrounding people to
hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notifi-
cation system is installed on the
front of the vehicle, it may be more
difficult to hear fr om the rear of the
vehicle compared to the front.

contact with a metallic object
●If the key is in close proximity to or
touching a key to the security sys-
tem (key with a built-in transpon-
der chip) of another vehicle
Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the hybrid sys-
tem from starting if a key
has not been previously
registered in the vehicle’s
on-board computer.
Never leave the keys inside
the vehicle when you leave
the vehicle.
This system is designed to
help prevent vehicle theft
but does not guarantee

●Fold the mirrors before washing
the vehicle. Start washing from the
front 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.
■High pressure car washes
As water may ent er the cabin, do not bring the nozzle tip near the
gaps around the doors or perimeter
of the windows, or spray these
areas continuously.
■When using a car wash
If the door handle becomes wet
while the electronic key is within the
effective range, the door may lock
and unlock repeatedly. In that case,
follow the following correction pro-
cedures to wash the vehicle:
●Place the key in a position 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.)
●Set the electronic key to bat-
tery-saving mode to disable the
smart key system. ( P.112)
■Aluminum wheels
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes

Maintenance and care
WA R N I N G
■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 touch-
ing a hot exhaust pipe can cause
burns.
■Precaution regarding the rear
bumper with Blind Spot Moni-
tor (if equipped)
If the paint of the rear bumper is
chipped or scratched, the system
may malfunction. If this occurs,
consult your Toyota dealer.
NOTICE
■To prevent paint deteriora-
tion and corrosion on the
body and components (alumi-
num 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 tre e 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 contami- nated with soot, oily smoke,
mine dust, iron powder or chem-
ical 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.
●To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use
organic substances or scrub
with a hard brush.
This may damage the surfaces
of the lights.
●Do not apply wax to the sur-
faces of the lights.
Wax may cause damage to the
lenses.
■To prevent damage to the
windshield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver
side wiper arm upward first, and
repeat for the passenger side.
When returning the wipers to their
original position , do so from the
passenger side first.
■When using a high pressure
car wash
●When washing the vehicle, do
not spray the camera or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts

3947-1. Maintenance and care
COROLLA HV_U
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
NOTICE
