The seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The seat belt pretensioner is controlled by the airbag
sensor assembly. The airbag sensor assembly consists
of a safing sensor and airbag sensor.
When a seat belt pretensioner is activated, an operating
noise may be heard and a small amount of smoke±like
gas may be released. This gas is harmless and does not
indicate that a fire is occurring.
Once the seat belt pretensioner has been activated, the
seat belt retractor remains locked.

177 When not using the child restraint system, keep it
secured with the seat belt or place it in the trunk or
somewhere other than in the passenger compartment.
This will prevent it from injuring passengers in the event
of a sudden stop or accident.
Your vehicle has anchor brackets for securing the top
strap of a child restraint system.
For instructions about how to use the anchor bracket,
see ªUsing a top strapº on page 197.To install an anchor bracket, use an 8 mm X 30 mm X
1.25 mm coarse thread metric bolt and a 15 mm (0.6 in.)
spacer for the outer anchors or a 10 mm (0.4 in.) spacer
for the center anchor. Note that the bolts accompanying
many child restraint systems are not metric. You can
damage the anchor nuts on your vehicle if you force
bolts with different thread into the anchor nuts.
For instructions about how to install the anchor bracket,
see ºTop strap anchors and locationsº.
If your child restraint system does not provide any of the
necessary parts, you can purchase the following items
from your Lexus dealer.

shoulder belt through or around the booster seat and
child following the instructions provided by its
manufacturer and insert the tab into the buckle.
Make sure the shoulder belt is correctly across the
child's shoulder and that the lap belt is positioned as low

loose±fitting belts could cause serious injuries
due to sliding under the lap belt during a
collision or other unintended result. Keep the
lap belt positioned as low on hips as possible.
