●Front corner sensors:
• Shift position is not in P
• Vehicle speed is approximately 10 km/h (6 mph) or less
●Front side sensors/rear side sensors:
• Shift position is not in P
• Vehicle speed is approximately 10 km/h (6 mph) or less
• Steering wheel is turned approximately 90 or more
●Front center sensors:
• Shift position is not in P or R
• Vehicle speed is approximately 10 km/h (6 mph) or less
●Rear corner sensors/rear center sensors:

■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
●Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●Obstacles may not be detected if they are too close to the sensor.
●There will be a short delay between obstacle detection and display. Even
when traveling at a low speed, if you come too close to an obstacle before
the display and buzzer activate, the display and buzzer may not activate at
all.
●Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
●It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

5046-1. Maintenance and care
PRIUS_OM_OM47F32E_(EE)
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 alco-
hol
● 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 of
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 windshield (vehicles with Toyota
Safety Sense)
Do not allow glass cleaner to contact the lens. Also, do not touch the lens.
( P. 2 8 3 )
■ 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.

When trouble arises
■The tire pressure warning light may come on due to natural causes (if
equipped)
The tire pressure warning light may come on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by temperature. In
this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (vehicles with the tire pressure
warning system)
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes flat, the tire pres-
sure warning light will not turn off even though the flat tire has been replaced
with the spare tire. Replace the spare ti re with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few
minutes.
Vehicles with full-size spare tire: T he spare tire is also equipped with a tire
pressure warning valve and transmitter. The tire pressure warning light will
turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat,
the tire pressure warning light will not turn off even though the flat tire has
been replaced with the spare tire. Replace the spare tire with the repaired tire
and adjust the tire inflation pressure. The tire pressure warning light will go off
after a few minutes.
■ Conditions that the tire pressure warning system may not function prop-
erly (if equipped)
 P. 533
■ If the tire pressure warning light frequently comes on after blinking for
1 minute (if equipped)
If the tire pressure warning light frequently comes on after blinking for
1 minute when the power switch is turned to ON mode, have it checked by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.

When trouble arises
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
reverse. After installing, check that the fixed pins are inserted
securely.
Once the hybrid system starts, have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■ When opening the cover of the positive (+) battery terminal
 P. 523
■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
● Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
● Some systems may require initialization. (P. 679)
■ When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
