WARNING
■Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( →P. 30)
■ When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
Obtain medical advice and wear the seat
belt in the proper way. ( →P. 30)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants. Extend the shoulder belt
completely over the shoulder and posi-
tion the belt across the chest. Avoid belt
contact over the rounding of the abdomi-
nal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

421-1. For safe use
PRIUS c_U (OM52G95U)
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU ) controls airbag deployment based on infor-
mation obtained from the sensors et c. shown in the system compo-
nents diagram above. This informat ion includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
WARNING
■ SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
● The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less than 10
in. (250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the ped- als comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary,
many drivers can achieve the 10 in. (250 mm) distance, even with the
driver seat all the way forward, simply by reclining the back of the seat
somewhat. If reclining the back of your seat makes it hard to see the
road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while
still maintaining control of the foot pedals, steering wheel, and your v\
iew
of the instrument panel controls.

WARNING
■SRS airbag precautions
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collisi\
on.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or per form any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags.
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails.
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches, or roof luggage carrier.
● Modifications to the vehicle’s suspension system.
● Installation of electronic devices such as mobile two-way radios and CD
players.
● Modifications to your vehicle for a person with a physical disability.

801-2. Hybrid system
PRIUS c_U (OM52G95U)
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cooling
the hybrid battery (traction bat-
tery). When the air intake vent is
blocked, the battery operations
will be restricted and cause a
decline in fuel consumption.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off sy stem activates, your vehicle will not restart.
To restart the hybrid system, contact your Toyota dealer.
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( →P. 490)

ture indicator ( →P. 97)
WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS or SRS warning light not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could r\
esult
in death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.

1423-2. Opening, closing and locking the doors
PRIUS c_U (OM52G95U)■
Notes for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, luggage cover or floor, in
the door pockets or glove box when the hybrid system is started or power
switch modes are changed.
● Do not exit the vehicle with the electronic key placed on the instrument
panel or near the door pockets. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door
will become lockable from the outside, possibly trapping the electronic key
inside the vehicle.
● As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Whether or not the electronic key is inside the vehicle, the hybrid system
could be started if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into con-
tact with ice, snow, mud, etc. Clean the sensors and attempt to operate
them again.
● If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Using the wireless remote control to unlock
the doors may resume the function.)
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key system. ( →P. 140)

Notes for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
■ Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the handle again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
● The smart key system can be deactivated in advance. Ask your Toyota
dealer for details.
