WARNING
■When installing a child restraint system
●If child restraint system regulations exist in the country where you reside, please con-
tact any authorized Lexus retailer or Le xus authorized repairer, or any reliable
repairer for the child rest raint system installation.
●When a junior seat is installed, always en sure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it could fall off the ch ild’s shoulder. Failing to do so may result in
death or serious injury in the event of su dden braking, sudden swerving or an acci-
dent.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufacturer.
■To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects around the
anchors and that the seat belt is not caught behind the child restraint system. Make sure
the child restraint system is se curely attached, or it may cause death or serious injury to
the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

WARNING
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.
■Seat adjustment
To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat
more than necessary.
If the seat is too reclined, th e lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.

■Recall procedure
Carry the electronic key that has been registered to the driving position,
and then unlock and open the driver’s door using the smart entry & start
system or wireless remote control.
The driving position will move to the reco rded position (not including the steering
wheel and HUD [head-up display] [if equipp ed]). However, the seat will move to a
position slightly behind the recorded position in order to make entering the vehicle
easier.
If the driving position is in a position that has already been recorded, the seat and
outside rear view mirrors will not move.
Turn the power switch to ACCESSORY mode or ON mode, or fasten a
seat belt.
The seat, steering wheel and HUD (head-up display) (if equipped) will move to the
recorded position.

Carry only the key you want to cancel and then close the driver’s door.
If 2 or more keys are in the vehicle, the driving position cannot be canceled
properly.
Turn the power switch to ON mode.
While pressing the “SET” button, press and hold the door lock switch
(either lock or unlock) until the buzzer sounds twice.
If the button could not be canceled, the buzzer sounds continuously for approxi- mately 3 seconds.
■Recalling the driving position us ing the memory recall function
●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart entry & start system, the
driving position cannot be recalled. In this case, press the driving position button which
has been set.
■Customization
The unlock door settings of the memory recall function can be customized.
