CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint systems for
children small enough to use them.
The laws of all fifty states in the U.S.A. now require the use
of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child
should sit in the rear seat and must be restrained using the
vehicle's seat belt. See ºSeat beltsº on page 115 for details.

2. To remove the child restraint system, press the
buckle±release button and allow the belt to retract.DRIVING POSITION MEMORYSYSTEM
The micro computer can memorize the position of the driver's
seat, the positions of the tilt and telescopic steering, and
outside rear view mirrors. Two different driving position
profiles can be entered into the computer's memory.
This can only be done when the ignition key is in the ºONº
position, and the selector lever is in the ºPº position.
Setting a driving position

COMFORT ADJUSTMENT
169
1. Adjust the driver's seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the ºSETº button, push button º1º or
º2º until the signal beeps.
The beep sound means that the positions are recorded in the
computer 's memory.
By repeating these two steps and pressing the remaining
button, the driving position for another driver can be
recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized
position, the easiest way is to first activate the memorized
position, then make the desired changes and perform step 2
above.Activating a memorized position

COMFORT ADJUSTMENT

When you push button º1º or º2º, the signal beeps and the
driving position automatically adjusts to the position
recorded for that button.
Conditions for memorized position activation

Ignition key ºONº
Selector lever in ºPº position
All parts of the memorized positions can be activated.
However, if the brake pedal is being depressed, the seat
position will not change.

Key not in ignition switch
Within 30 seconds of opening driver's door
The memorized position can be activated, except for the
tilt and telescopic steering. If any driving position memory switch is pushed while one of
the memorized driving position profiles is being activated,
the operation will stop.
To activate the system, push the desired button (º1º or º2º)
again.
The driving position memory control system cannot be
operated while the vehicle is moving.
If the vehicle's battery is disconnected, the computer's
memory
will be erased and the memorized positions will have
to be set again.

made.

Take care not to select the wrong button, or the seat could
strike the rear passenger or hit your body against the
steering wheel. If this happens, you can stop the movement
by pressing another driving position memory switch, or
depressing the brake pedal.
