CAUTION
■Burns
●Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■ To prevent 12-volt battery discharge
Turn the seat heaters off when the hybrid system is off.

Maintenance and care
NOTICE
■
Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
● Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration o\
f
leather surfaces:
●Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
■ When cleaning the inside of the wi ndshield (vehicles with LKA [Lane-
Keeping Assist])
Be careful not to touch the camera sensor ( P. 289).
If the camera is accidentally scratched or hit, LKA may not operate properly
or may cause a malfunction.
■ Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires. Use a cloth dampened
with lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires.
● Be careful not to scratch or damage the heater wires.

CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions
may occur and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resu lting from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or mo isture could get into the valve and
cause air leakage, which could result in an accident. If the caps are lost,
replace them as soon as possible.

Maintenance and care
CAUTION
■
Replacing light bulbs
●Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When i\
t is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.

CAUTION
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire ma intenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

Warning messageDetailsCorrection procedure
(If equipped) • Indicates that the pre-collision
system is not currently func-
tional because the grille or the
sensor is dirty.
• This message also appears when the pre-collision system
is not functional due to over-
heating. • Check the grille
and the sensor and
clean them if they
are dirty.
• In case of over- heating, the system
will become func-
tional once the sys-
tem cools down.
(Flashes)
(If equipped) Indicates that the radar cruise
control sensor is dirty or cov-
ered with ice.
Clean the sensor.
(Flashes)
(If equipped) Indicates that the radar cruise
control system is unable to
judge vehicle-to-vehicle dis-
tance.
If the windshield
wipers are on, turn
them off or set
them to either the
intermittent or the
slow mode.

PRIUS_OM_OM47857U_DVD_(U)
Warning messageDetailsCorrection procedure
(If equipped) Indicates that the LKA (Lane-
Keeping Assist) is suspended
• The camera sensor tempera-
ture is higher than the opera-
tion temperature range.
• The power steering system operation is restricted. Restart the LKA
after driving for a
while.
Alerts the driver that the vehi-
cle is out of the lanes (while
the LKA [Lane-Keeping Assist]
system is operating). The warning buzzer sounds
continuously. The lane mark-
ings and/or the steering
wheel marking flash.
At the same time,
will appear on the
head-up display (the image
flashes). Check around the
vehicle and back to
inside of the lane
markings.
Indicates that the LKA (Lane-
Keeping Assist) system
detects nohanded driving
(while the lane keeping assist
function is operating). The warning buzzer sounds
twice. Grip the steering
wheel firmly.
The hybrid system has over-
heated. A buzzer also sounds.
This message may be dis-
played when driving under
severe operating conditions.
(For example, when driving
up a long steep hill.) Stop and check.
