Before driving
CAUTION
■
While driving
●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, increasing the risk of
death or serious injury to the driver or passenger.
● 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. The adjustment mechanism may also be damaged.
■ Adjusting the seat position
●Do not recline the seat more than necessary when the vehicle is in motion,
to reduce the risk of sliding under the lap belt.
If the seat is too reclined during an accident, the lap belt may slide past the
hips and apply restraint forces directly to the abdomen or your neck may
contact the shoulder belt, increasing the risk of death or serious injury.
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.

1-7. Safety information
SRS airbags
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.
Front airbags
Driver airbag/front passenger airbag
Can help protect the head and chest of the driver and right front
passenger from impact with interior components.
Knee airbags
Can help provide driver and front passenger protection.
Side and curtain shield airbags
Side airbags
Can help protect the torso of the front seat occupants.
Curtain shield airbags
Can help protect primarily the head of outside seat occupants.

124 1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and right front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front center seating position.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants. Side airbags

■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.
■ Operating conditions (front airbags)
●The SRS front airbag will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 12-18 mph [20-30 km/h] frontal collision with a fixed wall that does
not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under, the
bed of a truck, etc.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbag will not activate if there is no passenger
sitting in the right front passenger seat. However, the front passenger air-
bag may deploy if luggage is put in the seat, or the seat belt is fastened,
even if the seat is unoccupied. ( P. 135)

126 1-7. Safety information
■Operating conditions (side airbag s and curtain shield airbags)
The SRS side airbags and SRS curtain shield airbags will deploy in the
event of an impact that exceeds the set threshold level (the level of force
corresponding to the impact force produced by an approximately 3307 lb.
[1500 kg] vehicle colliding with the vehicle cabin from a direction perpendicu-
lar to the vehicle orientation at an approximate speed of 12-18 mph [20-30
km/h]).
■ Operating conditions (side airbags)
The SRS side airbag on the passenger seat will activate even if there is no
passenger sitting in the right front passenger seat. ( P. 135)
■ Operating conditions (c urtain shield airbags)
The SRS curtain shield airbags are designed to inflate when the passenger
compartment is subjected to a severe impact from the side or vehicle roll-
over.
■ Conditions under which the SRS airbags may deploy (inflate), other
than a collision
The SRS front airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situation shown
in the illustration.
●Hitting a curb, edge of pavement or
hard surface
● Falling into or jumping over a deep hole
● Landing hard or vehicle falling
●The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.

■
Types of collisions that may not depl oy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate 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 suffi-
cient forward deceleration of the vehicle, deployment of the SRS front air-
bags may occur.
■ Types of collisions that may not deploy the SRS airbag
(side airbags and curtain shield airbags)
The SRS side airbag and curtain shield airbag system may not activate if the
vehicle is subjected to a collision from the side at certain angles, or a colli-
sion to the side of the vehicle body other than the passenger compartment.
The SRS side airbags are not generally designed to inflate if the vehicle is
involved in a frontal or rear collision, if it rolls over, or if it is involved in a low-
speed side collision.
● Collision from the side
● Collision from the rear
● Vehicle rollover
●Collision from the side to the vehicle
body other than the passenger com-
partment
● Collision from the side at an angle
●Collision from the front
● Collision from the rear
● Vehicle rollover

128 1-7. Safety information
The SRS curtain shield airbags are not generally designed to inflate if the
vehicle is involved in a frontal or rear collision, if it pitches end over end, or if
it is involved in a low-speed side collision.
■ When to contact your Toyota dealer
In the following cases, contact your Toyota dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●Collision from the front
● Collision from the rear
● Pitching end over end
●The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS airbags to inflate.
● A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain shield airbags to inflate.
● The pad section of the steering wheel,
dashboard near the front passenger air-
bag or lower portion of the instrument
panel is scratched, cracked or other-
wise damaged.
