back so that you are sitting
straight up and so that you do
not have to lean forward to
steer. (P. 1 4 7 )
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel. ( P. 147)
Lock the head restraint in place with the center of the head restraint
closest to the top of your ears. ( P. 1 5 7 )
Wear the seat belt correctly. ( P. 3 4 )
Make sure that all occupants are wearing their seat belts before driv-
ing the vehicle. ( P. 3 4 )

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 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 points the air- bag 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.
● 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.

461-1. For safe use
WARNING
■SRS airbag precautions
● Do not hang coat hangers or other hard objects on the coat hook s. All of
these items could become projectiles and may cause death or ser ious
injury, should the SRS curtain shield airbags deploy.
● If a vinyl cover is put on the area where the SRS knee airbag w ill deploy,
be sure to remove it.
● Do not allow anyone to kneel on the
passenger seats toward the door or put
their head or hands outside the vehicle.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
● Do not attach anything to areas such as
a door, windshield glass, side door
glass, front or rear pillar, roof side rail
and assist grip.
● Do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
SRS knee airbag inflation or be thrust
into the driver’s seat area by the force
of the deploying airbag, thus causing a
danger.

For safety and security
WARNING
■SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the air bags. Such
accessories may prevent the side airbags from activating correc tly, disable
the system or cause the side airbags to inflate accidentally, r esulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the S RS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deplo yed, open a
door or window to allow fresh air in, or leave the vehicle if i t is safe to do
so. Wash off any residue as soon as possible to prevent skin ir ritation.
● 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform 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 airbag s
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, s ide 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 radio s and CD
players
● Modifications to your vehicle for a person with a physical disa bility
