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
 P. 69
■ 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, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal 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.

For safety and security
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 information includes crash severity a nd
occupant information. As the airbags deploy, a chemical reaction 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 several
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.
