■Automatic locking retractor (ALR)
When a passenger's lap belt is comple tely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is

retract the belt and then pull the belt out once more. ( P. 8 0 )
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
■Child seat belt usage
The seat belts of your vehicle are principally designed for persons of adult size.
●Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle's seat belt. ( P. 76 )
●When the child becomes large enough to properly wear the vehicle's seat belt,
follow the instructions on P. 36 regarding seat belt usage.
■Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the

If seat belt regulations exist in the co untry where you reside, please contact your
Lexus dealer for seat belt replacement or installation.
Obtain medical advice and wear the seat belt

the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.

CAUTION
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading to choking or other serious in juries that could result in death.
If this occurs and the buckle cannot be un fastened, scissors should be used to cut
the belt behind the seat belt guide.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
If the seat belt is damaged, the built-in SRS seat belt airbag may not inflate in an
accident.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
●Ensure that the belt and tab are lo cked and the belt is not twisted.
If the seat belt does not function co rrectly, immediately contact your Lexus
dealer.
●If your vehicle has been involved in an accident, have the seat assembly including
the belts inspected at your Lexus dealer even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may prevent it from operating properly resulting in
death or serious injury.
■When using the seat belt guide
●Always make sure that the belt is not twisted, and runs freely through the guide.
●Always make sure the seat belt passes through the seat belt guide. If the seat belt
is not passing through the seat belt guide correctly and the SRS airbags are
inflated, the SRS seat belt airbag may no t inflate correctly, resulting in death or
serious injury.

■The mirrors can be adjusted when
The ignition switch is in the “ACC” or “ON” position.
■Rain clearing mirrors
When water droplets collects on the mirror surface, for example when it rains, the
rain clearing (hydrophilic) effect of the mirrors causes the droplets to be spread out
into a film making the rear view clearer. In the following cases, the rain clearing
effect will be reduced temporarily, but wi ll return after 1 or 2 days' exposure to
direct sunlight.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After your vehicle has been parked for a long period in underground parking
lots etc. where there is no direct sunlight
■When the mirrors are fogged up
Turn on the mirror defoggers to defog the mirrors. ( P. 2 0 1 )
CAUTION

Failing to do so may result in loss of control of the vehicle and cause an accident,
resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded back.
●Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your hand
caught by the moving mirror.
