WARNING
■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 sh ould 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e 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 c ome on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor (front seats)
Always make sure the shoulder belt is positioned across the cen ter of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of prot ection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 31)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or bu ckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fray ing, and loose
parts. Do not use a damaged seat belt until it is replaced. Dam aged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately conta ct your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious dam age.
● Do not attempt to install, remove, modify, disassemble or dispo se of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling may lead to incorrect operation.

For safety and security
MIRAI_OM_USA_OM62073U
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 etc. shown in the system compo -
nents diagram above. This informat ion includes crash severity and
occupant information. As the airbags deploy, a chemical reactio n in
the inflators quickly fills the airbags with non-toxic gas to h elp restrain
the motion of t he 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 se at belts
properly.
The SRS airbags are supplemental devices to be used with the se at 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) advi ses:
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 sev-
eral ways:
• Move your seat to the rear as far as you can while still reach ing 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 ba ck of your
seat makes it hard to see the road, raise yourself by using a f irm, non-
slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This p oints the
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, whil e
still maintaining control of the foot pedals, steering wheel, and your view
of the instrument panel controls.
