●Gripping the door handle when wearing a glove may not unlock the door.
●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
smart access system with push-button start. (Use the wireless remote control to
unlock the doors.)
●A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door handle
again.

CAUTION
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to fall closed again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to fall closed again after
it is opened.
●The trunk lid may fall if it is not opened
fully. It is more difficult to open or close
the trunk lid on an incline than on a level
surface, so beware of the trunk lid unex-
pectedly opening or closing by itself.
Make sure that the trunk lid is fully open
and secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (→P. 74 )
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriately for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt. ( →P. 121)
●When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions on P. 74 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
first collision, but will not activate for the second or subsequent collisions.
■Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

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
●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 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 is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of a seat belt.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may cause it to activate or operate improperly and may
cause death or serious injury.
■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 a sudden stop, sudden swerve or 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.
■Precaution for pre-collision seat belts
Do not rely solely on the pre-collision system to avoid accidents. Always pay atten-
tion to the surrounding conditions, and drive safely and responsibly.
