WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
NOTICE
■ Hybrid battery (tract ion battery) charge
If the shift lever is in N, the hybrid battery (traction batter y) will not be
charged even when the engine is running. Therefore, if the vehi cle is left
with the shift lever in N for a long period of time, the hybrid battery (traction
battery) will discharge, and this may result in the vehicle not being able to
start.

When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.

2224-4. Refueling
PRIUS c_U
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks re sulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosen ed.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing f rom the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission c ontrol
system to operate abnormally or damaging fuel system components or the
vehicle's painted surface.

WARNING
■When replacing the fuel tank cap

■ Toyota Safety Sense C
The Toyota Safety Sense C is designed to operate under the assu mption
that the driver will drive safely, and is designed to help redu ce the impact to
the occupants and the vehicle in the case of a collision or ass ist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e's surround-
ings and driving safely.

WARNING
■Front sensor
The front sensor uses lasers to detect vehicles ahead of your vehicle. The
front sensor is classified as class 1M laser product according to the IEC
60825-1 standard. Under normal usage conditions, these lasers a re not
harmful to the naked eye. However, it is necessary to observe the following
precautions.
Failure to do so may result in the loss of eyesight or severe v isual impair-
ment.
● To avoid hazardous laser radiation exposure, never attempt to d isassem-
ble the front sensor (e.g. remove the lenses). When disassemble d, the
front sensor is classified as a class 3B laser product accordin g to the IEC
60825-1 standard. Class 3B lasers are hazardous and pose a risk of eye
injury under direct exposure.
● Do not attempt to look into the front sensor with a magnifying glass, micro-
scope or other optical instrument within a distance of less tha n 3.9 in.
(100 mm).

WARNING
■To avoid malfunction of the front sensor
Observe the following precautions.
Otherwise, the front sensor may not operate properly, possibly leading to an
accident resulting in death or serious injury.
● Keep the windshield clean at all times. If the windshield is di rty or covered
with an oily film, water droplets, snow, etc., clear the windshield. If the
inner side of the windshield in front of the front sensor is dirty, contact your
Toyota dealer.
● If there is a large difference in temperature between the inside and outside
of the vehicle, such as in winter, the windshield is likely to fog up easily. If
the part of the windshield in front of the front sensor is fogg ed up or cov-
ered with condensation or ice, the PCS warning light may illumi nate and
the system may be temporarily disabled. In this case, use the w indshield
defogger to remove the fog, etc. ( P. 378)
● If the area of the windshield in front of the front sensor is covered with
water droplets, use the windshield wipers to remove them.
If the water droplets are not sufficiently removed, the performance of the
front sensor may be reduced.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration).
A: From the top of the windshield to
approximately 4.0 in. (10 cm) below the
bottom of the front sensor
B: Approximately 7.9 in. (20 cm)
(Approximately 4.0 in. (10 cm) to the
right and left from the center of the front
sensor)
● Do not install or attach anything to the
inner side of the windshield under the
front sensor (shaded area in the illustra-
tion).
A: Approximately 4.0 in. (10 cm) (Start-
ing from the bottom of the front sensor)
B: Approximately 7.9 in. (20 cm)
(Approximately 4.0 in. (10 cm) to the

● Do not subject the front sensor to a strong impact.
● Do not change the installation position or direction of the fro nt sensor or
remove it.
● Do not disassemble the front sensor.
● Do not modify any components of the vehicle around the front sensor
(inside rear view mirror, etc.) or ceiling.

■If a warning message is displayed on the multi-information disp lay
A system may be temporarily unavailable or there may be a malfu nction in
the system.
● In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the warning messa ge will dis-
appear and the system will become operational.

SituationActions
When the area around the front
sensor is covered with dirt,
moisture (fogged up, covered
with condensation, ice, etc.), or
other foreign matterTo clean the part of the windshield in front
of the front sensor, use the windshield
wipers or the windshield defogger
( P. 378).
When the temperature around
the front sensor is outside of
the operational range, such as
when the vehicle is in the sun or
in an extremely cold environ-
ment
If the front sensor is hot, such as after the
vehicle is parked in the sun, use the air
conditioning system to decrease the tem-
perature around the front sensor.
If a sunshade was used when the vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature of the front sensor to become
excessively high.
If the front sensor is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front sensor.
The area in front of the front
sensor is obstructed, such as
when the hood is open or a
sticker is attached to the part of
the windshield in front of the
front sensor.
Close the hood, remove the sticker, etc.
to clear the obstruction.
