WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 38)
■ When children are in the vehicle
 P. 8 0
■ Seat belt pretensioners
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 any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■ 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 twisted.
If the seat belt does not function correctly, immediately contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● 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 dispose of the
seat belts. Have any necessary repairs carried out by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. Inap-
propriate handling may lead to incorrect operation.

SRS airbags
◆SRS front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front passen-
ger from impact with interior components
SRS driver knee airbag (if equipped)
Can help provide driver protection
◆SRS side and curtain shield airbags
SRS side airbags
Can help protect the torso of the front seat occupants
SRS curtain shield airbags (if equipped)
Can help protect primarily the head of occupants in the outer seats
The SRS airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury to the
occupants. They work together with the seat belts to help reduce
the risk of death or serious injury.

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.
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 seat belts
properly.
The SRS airbags are supplemental devic es to be used with the seat 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.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.)
of inflation, placing yourself 250 mm ( 10 in.) 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
250 mm (10 in.) 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 reaching the ped-
als comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary,
many drivers can achieve the 250 mm (10 in.) distance, even with the
driver seat all the way forward, simply by reclining the back of the seat
somewhat. If reclining the back 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
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.

WARNING
■SRS airbag precautions
● The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the
airbag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 62)
●Do not sit on the edge of the seat or
lean against the dashboard.
● Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.

WARNING
■SRS airbag precautions
●Vehicles without SRS curtain shield
airbags: Do not lean against the front
door.
● Vehicles with SRS curtain shield
airbags: Do not lean against the door,
the roof side rail or the front, side and
rear pillars.

passenger seat toward the door or put
their head or hands outside the vehicle.
● Vehicles without an SRS driver knee
airbag: Do not attach anything to or lean
anything against areas such as the
dashboard or steering wheel pad.
These items can become projectiles
when the SRS driver and front passen-
ger airbags deploy.
● Vehicles with an SRS driver knee
airbag: Do not attach anything to or lean
anything against areas such as the
dashboard, steering wheel pad and
lower portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger

WARNING
■SRS airbag precautions
● Do not strike or apply significant levels of force to the area of the SRS
airbag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS
airbags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● Vehicles without SRS curtain shield airbags: If the areas where the SRS
airbags are stored, such as the steering wheel pad, are damaged or
cracked, have them replaced by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
● Vehicles with SRS curtain shield airbags: 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 any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side 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
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios (RF-trans-
mitter) and CD players

■ Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS curtain shield airbags (if equipped) may also
deploy if a serious impact occurs to the underside of your vehicle. Some
examples are shown in the illustration.
■ Types of collisions that may not deploy the SRS airbags (SRS front
airbags)
The SRS front airbags do not generally infl ate if the vehicle is involved in a
side or rear collision, if it rolls over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the SRS front airbags may occur.
● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● Collision from the side
● Collision from the rear
● Vehicle rollover

wheel or dashboard near the front pas-
senger airbag is scratched, cracked, or
otherwise damaged.
