■Impact detection door lock release system
In the event that the vehicle is subject to a strong impact, all the doors are unlocked.
Depending on the force of the impact or the type of accident, however, the system
may not operate.
■Using the mechanical key
The doors can also be locked and unlocked with the mechanical key. (P. 4 7 7 )
■Customization that can be configured at Lexus dealer
Settings (e.g. unlocking function using a key) can be changed.
(Customizable features P. 515)
CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failing to do so may result in a door opening and an occupant falling out, resulting in
death or serious injury.
●Always use a seat belt.
●Always lock all doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the doors while driving.
The doors may be opened and the passengers are thrown out of the vehicle and it
may result in serious injury or death.
Be especially careful for the front doors, as the doors may be opened even if the
inside lock buttons are in locked position.
●Set the rear door child protector locks when children are seated in the rear seat.

Before driving
CAUTION
■Caution while driving
●Keep the trunk lid closed while driving.
If the trunk lid is left open, it may hit near-by objects while driving or luggage in
the trunk may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a serious
health hazard. Make sure to close the trunk lid before driving.
●Before driving the vehicle, make sure that the trunk lid is fully closed. If the trunk
lid is not fully closed, it may open unexpectedly while driving, causing an accident.
●Never let anyone sit in the trunk. In the event of sudden braking or a collision, they
are susceptible to death or serious injury.
■When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not allow children to enter the trunk.
If a child is accidentally locked in the trunk, they could overheat or suffocate.
●Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to operate unexpectedly, or cause the child’s
hands, head, or neck to be caught by the closing trunk lid.

Before driving
Pre-collision seat belts (front seats of vehicles with pre-collision system)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt, helping to enhance occupant
protection.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (P. 1 8 4 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward or pull out the belt too quickly. Allow the belt to fully retract, and
then slowly extend the belt. If the belt cannot be pulled out of the retractor, firmly
pull the belt and release it. You will then be able to smoothly pull the belt out of the
retractor.
■Automatic locking retractor (ALR)
When a passenger's shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the child restraint system (CRS) firmly. To free the belt again, fully
retract the belt and then pull the belt out once more. (P. 1 0 6 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (P. 5 7 )
Women who are pregnant should position
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.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.

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 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 seating position other than the one originally
intended.
