■Note for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent lock
operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition signals
will be shown up to two consecutive times. After this, no recognition signals will
be given.
●If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position 6 ft.
(2 m) or more separate from the vehicle while the vehicle is being washed. (Take
care to ensure that the key is not stolen.)
●If the electronic key is inside the vehicle and a door handle becomes wet during
a car wash, a message may be shown on the multi-information display and a
buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow,
mud, etc. Clean the lock sensor and attempt to operate it again, or use the lock
sensor on the lower part of the door handle.
●Fingernails may scrape against the door during operation of the door handle.
Be careful not to injure fingernails or damage the surface of the door.

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, thus enhancing the effectiveness
of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( →P. 3 4 3 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudde n stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■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. 151)

CAUTION
■When the children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead 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 pretensioners
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so
will disperse the passenger’s weight, which prevents the sensor form detecting
the passenger’s weight properly. As a result, the seat belt pretensioner for the
front passenger’s seat may not activate in the event of a collision.
●If the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from your neck, but not falling off your shoulder.
Failure to do so could reduce the amount of protection in an accident and cause
death or serious injuries in a collision. (→P. 8 6 )
