The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification indicator light
4. Front passenger occupant classification system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Airbag sensor assembly The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.CAUTION
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result
in death or serious injury. Consult
your Toyota dealer about any repair
and modification.
Do not modify or change the sus-
pension system. Such changes may
cause the curtain shield airbags to
inflate accidentally, which could re-
sult in death or serious injury. Con-
sult your Toyota dealer about any
repair and modification.
Do not use tires or wheels other
than the manufacture’s recom-
mended size. Such a use may cause
the curtain shield airbags and seat
belt pretensioners to inflate acci-
dentally, which could result in death
or serious injury. For details, see
Checking and replacing tires" on
page 443 in Section 7−2.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags and seat belt
pretensioners to inflate accidentally,
which could result in death or seri-
ous injury. For details, see Roof
luggage carrier" on page 334 in
Section 1−10.

TOWING CONNECTOR FOR TRAILER
LIGHTS
Your vehicle is equipped with a wire
harness stored in the rear end under
body. Some models are fitted with a
socket for trailer lights under the rear
bumper. Use either of them to connect
and operate the trailer lights. However,
the trailer lights must comply with fed-
eral, state/provincial and local regula-
tions. See your local recreational ve-
hicle dealer or rental agency for the
correct type of wiring and relays for
your trailer. Check for correct operation
of the turn signals and stop lights each
time you hitch up. Direct splicing may
damage your vehicle’s electrical system
and cause a malfunction of your lights.
The towing connector can be also con-
nected to the trailer brake and trailer
sub battery.
