1-2. Opening, closing and locking the doors and trunk
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.

Before driving
■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. 1 0 9 )
●When the child becomes large enough to properly wear the vehicle's seat belt,
follow the instructions on P. 60 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 cann ot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

Before driving
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 se rious 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 co rrectly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belt s, 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 child 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 seatin g position other than the one originally
intended.
