Fastening front and rear seat belts
G16009
Adjust the seat as needed and sit up straight and well back
in the seat. To fasten your belt, pull it out of the retractor
and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the
seat position.
The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly. A slow,
easy motion will allow the belt to extend, and you can move
around freely.
OCCUPANT RESTRAINT SYSTEMS
When a seat belt is completely extended and is then retracted
even slightly, the belt is locked in that position and cannot be
extended. This feature is used to hold the child restraint
system securely. (For details, see "Child restraint" on page
182.) To free the belt again, fully retract the belt and then pull
the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly pull
the belt and release it. You will then be able to smoothly pull
the belt out of the retractor.
CAUTION
D After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
D Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
D If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.
