*: If equipped
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. As
the airbags deploy, a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the motion of the occu-
pants.

911-3. Hybrid system
1
For safety and security
YARIS_HV_OM_Europe_OM52J66E
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 system activates, your vehicle will not restart.
To restart the hybrid system, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
A message is automatically displayed 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.

Operation of each component
YARIS_HV_OM_Europe_OM52J66E
■ Notes for the entry function (vehicles with an entry function)
● Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following case:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place w hen the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the back door is opened.
• The electronic key is on the instrument panel, luggage cover (if equipped)
or floor, or in the door pockets, glove box, accessory box of the instru-
ment panel, or in/near the front cup holder when the engine is started or
engine switch modes are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the out side, 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.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the engine 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
30 seconds if the doors are not opened and closed.)
● 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. (Use the wireless remote control to unlock
the doors.)
● Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.

1703-2. Opening, closing and locking the doors
YARIS_HV_OM_Europe_OM52J66E
● 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 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 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
● Vehicles with monochrome display: If the electronic key is inside the vehicle
and a door handle becomes wet during a car wash, a buzzer will sound out-
side the vehicle. To turn off the alarm, lock all the doors.
● Vehicles with color display: If the electronic key is inside the vehicle and a
door handle becomes wet during a car wash, a message may be shown on
the multi-information display and a buzzer will sound outside the vehicle. To
turn off the alarm, lock all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● A sudden handle operation or a handle operation immediately after entering
the effective range may prevent the doors from being unlocked. Touch the
door unlock sensor and check that the doors are unlocked before pulling the
door 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 2 m
(6 ft.) of the vehicle.
● The smart entry & start system can be deactivated in advance. (P. 603)
