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 should be used
to cut the belt.
■ Seat belt pretensioners (front seats)
● 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.
■ 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 protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or an accident. ( P. 31)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not t wisted.
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 damage.
● 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 of the pretensioner may prevent it from operating
properly, resulting in death or serious injury.

381-1. For safe use
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 com po-
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 i n 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 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 view
of the instrument panel controls.
● If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also been
fastened to the latch plate of the seat
belt, the SRS front airbags will judge
that the driver and front passenger are
wearing the seat belt even though the
seat belt has not been connected. In
this case, the SRS front airbags may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.

481-1. For safe use
Front passenger occupant classification
system
Your vehicle is equipped with a front passenger occupant classi -
fication system. This system det ects the conditions of the front
passenger seat and activates or deactivates the devices for the
front passenger.
