While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow sitting on top of a
foldeddown seatback, or in the
luggage compartment or cargo area.
Persons not properly seated and/or
properly restrained by seat belts
can be severely injured in the event
of emergency braking or a collision.
During driving, do not allow pas-
sengers to stand up or move
around between seats. Severe inju-
ries can occur in the event of emer-
gency braking or a collision.
CAUTION
The SRS side airbags are installed in
the driver and front passenger seats.
Observe the following precautions.
Do not lean against the front door
when the vehicle is in use, since
the side airbag inflates with consid-
erable speed and force. Otherwise,
you may be killed or seriously in-
jured.
Do not use accessories for the
seats which cover the parts where
the side airbags inflate. Such acces-
sories may prevent the side airbags
from activating correctly, causing
death or serious injury.
Do not modify or replace the seats
or upholstery of the front seats
with the side airbags. Such changes
may disable the system or cause
the side airbags to inflate acciden-
tally, resulting in death or serious
injury. Consult your Toyota dealer if
you insist on modifications of this
kind.
Adjust the driver’s seat so that the foot
pedals, steering wheel and instrument
panel controls are within easy reach of
the driver.
CAUTION
Adjustments should not be made
while the vehicle is moving, as the
seat may unexpectedly move and
cause the driver to lose control of
the vehicle.
When adjusting the seat, be careful
that the seat does not hit a passen-
ger or luggage.
After adjusting the seat position,
try sliding it forward and backward
to make sure it is locked in posi-
tion.
After adjusting the seatback, push
back your body to make sure it is
locked in position.

This indicator comes on when the igni-
tion key is turned to the “ACC” or
“ON” position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources. (For details, see “Service remain-
der indicators and warning buzzers” in
Section 15.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor. When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smokelike
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing so may
cause sudden operation of the front
seat belt pretensioners or disable the
system, which could result in death
or serious personal injury.
Failure to follow these instructions
can result in death or serious inju-
ries. Consult your Toyota dealer
about any repairs and modifications.
