Operation of each component
LS600h/LS600hL_EE(OM50G20E)
■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 2 m (6 ft.) of the
vehicle.
■Alarm (if equipped)
Using the smart entry & start system to lock the doors will set the alarm system.
( P. 103)
■To operate the system properly
●Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not oper-
ate.)
●Do not leave the electronic key inside the trunk.
The key confinement prevention function may not operate, depending on the loca-
tion of the key (close to a spare tire [if equipped], the inside edge of the trunk), con-
ditions (inside a metal bag, close to metallic objects) and the radio waves in the
surrounding area. ( P. 182)
■If the smart entry & start system does not operate properly
●Locking and unlocking the doors and trunk: Use the mechanical key. (P. 603)
●Starting the hybrid system: P. 605

■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery is low, an alarm will sound in the cabin when the hybrid system is
started or stopped. ( P. 154)
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart entry & start system or the wireless
remote control does not operate, or the detection area becomes smaller, the bat-
tery may be depleted. Replace the battery when necessary. ( P. 532)
●To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■When the electronic key battery is fully depleted
