Make sure that you can see backward clearly by adjusting the inside
and outside rear view mirrors properly. ( P. 178, 180)
Adjusting the mirrors
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint.
● Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent and the adjustment mechanism may also be damaged.
● Always observe the legal speed limit when driving on public roads.
● When driving over long distances, take regular breaks before you start to
feel tired.
Also, if you feel tired or sleepy while driving, do not force yourself to con-
tinue driving and take a break immediately.

Vehicles without SRS side and curtain shield airbags
The pretensioners help the seat
belts to quickly restrain the occu-
pants by retracting the seat belts
when the vehicle is subjected to
certain types of severe frontal col-
lision.
The pretensioners do not activate
in the event of a minor frontal
impact, a side impact, a rear
impact or a vehicle rollover.
Vehicles with SRS side and curtain shield airbags
The pretensioners help the seat belts to quickly restrain the occupants
by retracting the seat belts when the vehicle is subjected to certain
types of severe frontal or side collision.
The pretensioners do not activate in t he event of a minor frontal impact, a
minor side impact, a rear impact or a vehicle rollover.
■ Emergency locking retractor (ELR) (3-point type seat belt)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. (  P. 6 5 )
● When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. ( P. 40)
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for
the first collision, but will not activate for the second or subsequent collisions.
■ Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer for seat belt repl acement or installation.

For safety and security
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 are 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
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 40)
Obtain medical advice and wear the seat
belt in the proper way. ( P. 40)
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
■When children are in the vehicle
 P. 8 9
■ 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 any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■ Adjustable shoulder anchor (if equipped)
Always make sure the shoulder belt is positioned across the center 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 accident. ( P. 41)
■ 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.

senger from impact with interior components
SRS driver’s knee airbag
Can help provide driver protection
◆SRS side and curtain shield airbags
SRS side airbags (if equipped)
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

For safety and security
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 air-
bag 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.

HILUX_OM_OM0K789E_(EE)
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 air-
bag 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 (if equipped) of the vehi cle and properly restrained. The rear
seats (if equipped) are safer for infants and children than the front passen-
ger seat. ( P. 65)
●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.
