OCCUPANT RESTRAINT SYSTEMS
Pregnant woman. Lexus recommends the use of a seat belt.
Ask your doctor for specific recommendations. The lap belt
should be worn securely and as low as possible over the hips
and not on the waist.
Injured person. Lexus recommends the use of a seat belt.
Depending on the injury, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats properly wearing
their seat belts whenever the vehicle is moving.
Otherwise, they are much more likely to suffer serious
bodily injury or death in the event of sudden braking or
a collision.
When using the seat belts, observe the following:
D Use the belt for only one person at a time. Do not use
a single belt for two or more people - even children.
D To reduce the risk of sliding under the lap belt during
a collision, avoid reclining the seatback any more
than needed. The seat belts provide maximum
protection in a frontal or rear collision when the
driver and the front passenger are sitting up straight
and well back in the seats. If you are reclined, the lap
belt may slide past your hips and apply restraint
forces directly to the abdomen. In the event of a
frontal collision, the more the seat is reclined, the
greater the risk of personal injury.

D Be careful not to damage the belt webbing or
hardware. Take care that they do not get caught or
pinched in the seat or doors.
D Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
D Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners, or allow them
to come into contact with the belt - they may severely
weaken the belts. (See "Cleaning the interior" on
page 375 for instructions.)
D Replace the belt assembly (including bolts) if it has
been used in a severe impact. The entire assembly
should be replaced even if damage is not obvious.
