Toyota 2005 4Runner Owner's Manual page 81

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
D
open the seat belt pretensioner as-
semblies, airbag sensor or
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.
