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 injuries that could result in death. If this occurs
and the buckle cannot be unfastened, scissors should be used to cut the belt.
■Seat belt damage and wear
Inappropriate handling of the pretensioner may prevent it from operating properly
resulting in death or serious injury.
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●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 locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there's 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.
■Using a seat belt extender
●Do not wear the seat belt extender if you can fasten the seat belt without the
extender.
●Do not use the seat belt extender when installing a child restraint system because
the belt will not securely hold the chil d restraint system, increasing the risk of
death or serious injury in the event of an accident.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.

CAUTION
■Using a seat belt comfort guide
Failure to observe the following precautions could reduce the effectiveness of the
seat belt in an accident, causing death or serious injury.
Always make sure the shoulder belt is positioned across the center of the shoulder.
The belt should be kept away from the neck, and should not fall off the shoulder.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender,
not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.

■Linked mirror function when reversing (vehicles with driving position memory)
The outside rear view mirrors will automatically angle downwards when the vehicle
is reversing in order to give a better view of the ground. However, this function will
not operate when the mirror select switch is in the neutral position (between “L” and
“R”).
■Auto anti-glare function (vehicles with sports or luxury package)
When the anti-glare inside rear view mirror is set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view mir-
ror to reduce reflected light. ( →P. 7 2 )
■Rain clearing mirrors (if equipped)
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 will return after 1 or 2 days' exposure to
direct sunlight.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After waxing your vehicle in an automatic car wash
●After your vehicle has been parked for a long period in underground parking
lots, etc. where there is no direct sunlight
