WARNING
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants a re sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. ( P. 36)
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.

WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 36)
■ When children are in the vehicle
 P. 9 1
■ Seat belt pretensioners
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 a t any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ 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. 37)
■ 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. 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 any autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there’s no obvious dama ge.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by any autho rized
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 pas -
senger from impact with interior components
SRS driver’s knee airbag (if equipped)
Can help provide driver protection
◆SRS side and curtain shield airbags
SRS front side airbags
Can help protect the torso of the front seat occupants
SRS curtain shield airbags
Can help protect primarily the head of occupants in the outer
seats
The SRS airbags inflate when the vehicle is subjected to certai n
types of severe impacts that may cause significant injury to th e
occupants. They work together with the seat belts to help reduc e
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 quickl y fills the
airbags with non-toxic gas to help restrain the motion of the o ccu-
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 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.
Since the risk zone for the driver’s airbag is the first 50 - 7 5 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 measu red 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 reach ing the ped-
als comfortably.
• Slightly recline the back of the seat. Although vehicle design s vary,
many drivers can achieve the 250 mm (10 in.) distance, even wit h the
driver seat all the way forward, simply by reclining the back o f the seat
somewhat. If reclining the back of your seat makes it hard to s ee 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 p oints the
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still m aintain-
ing control of the foot pedals, steering wheel, and your view o f 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 passe nger 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 pas senger 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 res traint sys-
tem. Toyota strongly recommends that all infants and children b e placed in
the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 59)
●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.
● Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.

WARNING
■SRS airbag precautions
●Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
● Vehicles without SRS driver’s 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 SRS driver’s knee airbag:
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 driver’s knee airbag deploy.
● Do not attach anything to areas such as
a door, windshield, side door glass,
front or rear pillar, roof side rail and
assist grip. (Except for the speed limit
label: P. 705)

WARNING
■SRS airbag precautions
● Vehicles with SRS driver’s knee airbag: If a vinyl cover is put on the area
where the SRS driver’s knee airbag will deploy, be sure to remo ve it.
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the side airbags from activating c orrectly,
disable the system or cause the side airbags to inflate acciden tally, result-
ing in death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS
airbag components or the front doors.
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 side 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.
● 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 authorized Toyota retailer or Toyota autho rized
repairer, or any reliable repairer.
