Operation of each component
LS600h/LS600hL_EE(OM50G20E)
■Operating the driving position memory after turning the power switch off
Driver’s seat:
Recorded driving positions (except the steering wheel position) can be recalled up
to 180 seconds after the driver’s door is opened and up to 60 seconds after it is
closed again.
Front passenger’s seat:
Recorded seat positions can be recalled up to 180 seconds after the front passen-
ger’s door is opened.
■In order to correctly use the driving position memory function
If a seat position is already in the furthest possible position and the seat is operated in
the same direction, the recorded position may be slightly different when it is recalled.
Each electronic key (including a card key) can be registered to recall your
preferred driving position.
■Registering procedure
Record your driving position to switch “1”, “2” or “3” before performing
the following:
Using the wireless remote control
Turn the power switch off and close the driver’s door.
While pressing the desired
switch (“1”, “2” or “3”), press
on the wireless remote
control until the buzzer
sounds.
To prevent unintended triggering of the alarm, open and close a door
once after a driving position has been recorded. (If a door is not
opened within 30 seconds after is pressed, the doors will be locked
again and the alarm will automatically be set.)
In case that the alarm is triggered, immediately stop the alarm.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is intended to
assist the driver in avoiding collisions through the process of LOOK-JUDGE-ACT.
There are limits to the degree of assistance the system can provide, so please keep
in mind the following important points.
●Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in front of the
vehicle, and only within a limited range. It is not a mechanism that allows careless
or inattentive driving, and it is not a system that can assist the driver in low-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
When attempting to estimate the likelihood of a collision, the only data available
to the pre-crash safety system is that from obstacles it has detected directly in
front of the vehicle. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of collision in any
given situation.
●Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce
the severity of a collision, and so only acts when the system has judged that a col-
lision is unavoidable. This system is not capable of automatically avoiding a colli-
sion or bringing the vehi cle to a stop safely without appropriate operations
performed by the driver. For this reason, when encountering a dangerous situa-
tion the driver must take direct and immediate action in order to ensure the safety
of all involved.
NOTICE
■Precautions for cleaning the driver monitor sensor (vehicles with driver monitor
system)
●Gently wipe the sensor with a soft cloth to prevent damage.
●Wipe any excess dirt with a cloth dampened with neutral detergent, all liquids
having been wringed out of the cloth. After that, wipe again with a dry cloth.
●Do not use benzene, thinner, glass cleaners, wax, etc.
