Maintenance and care
The 12-volt battery is located in the
trunk.
■Before recharging
When recharging, the 12-volt battery pro- duces hydrogen gas which is flammable and explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the 12-volt battery
installed on the vehicle, be sure to discon- nect the ground cable.
●Make sure the power switch on the char-ger is off when connecting and discon-necting the charger cables to the 12-volt
battery.
■After recharging/reconnecting the 12- volt battery
●Unlocking the doors using the smart entry & start system may not be possible immediately after reconnecting the 12-
volt battery. If this happens, use the wire- less remote control or the mechanical key to lock/unlock the doors.
●Start the engine <hybrid system> with the engine switch <power switch> in ACCES-
SORY mode. The engine <hybrid sys- tem> may not start with the engine switch <power switch> turned off. However, the
engine <hybrid system> will operate nor- mally from the second attempt.
●The engine switch <power switch> mode
is recorded by the vehicle. If the 12-volt battery is reconnected, the vehicle will return the engine switch <power switch>
mode to the status it was in before the 12- volt battery was disc onnected. Make sure to turn off the engine switch <power
switch> before disconnect the 12-volt bat- tery. Take extra care when connecting the 12-volt battery if the engine switch
<power switch> mode prior to discharge is unknown.
If the engine <hybrid system> will not start even after multiple attempts at all methods above, contact any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.

If the electronic key does not
operate properly
If communication between the
electronic key and vehicle is inter-
rupted ( P.124) or the electronic
key cannot be used because the
battery is depleted, the smart entry
& start system and wireless remote
control cannot be used. In such
cases, the doors and trunk can be
opened and the engine <hybrid sys-
tem> can be started by following
the procedure below.
NOTICE

ponents when the vehicle is running at a low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or
discharged
●Information stored in the ECU is cleared.
When the 12-volt battery is depleted, have the vehicle inspected at any autho-rized Lexus retailer or Lexus authorized
repairer.
●Some systems may require initialization.
( P.436)
■When removing the 12-volt battery ter- minals
When the 12-volt battery terminals are removed, the information stored in the ECU is cleared. Before removing the 12-
volt battery terminals, contact any autho- rized Lexus retailer or Lexus authorized repairer.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the
vehicle is not in use, due to natural dis- charge and the draining effects of certain
electrical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-charge, and the engine <hybrid system>
may be unable to start. (The 12-volt battery recharges automatically during driving.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart entry &
start system when the 12-volt battery is discharged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
●The engine <hybrid system> may not start
on the first attempt after the 12-volt bat- tery has recharged but will start normally after the second attempt. This is not a
malfunction.
●The engine switch <power switch> mode
is memorized by the vehicle. When the 12-volt battery is reconnected, the system will return to the mode it was in before
the 12-volt battery was discharged.
Before disconnecting the 12-volt battery, turn the engine switch <power switch> off. If you are unsure what mode the engine
switch <power switch> was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
●If the 12-volt battery discharges, it may
not be possible to shift the shift position to other positions. In this case, the vehicle cannot be towed without lifting both rear
wheels because the rear wheels will be locked. ( P.363)
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt battery (European Regulations).
●LC500: Use a 12-volt battery that the case size is same as the previous one (LN4), 20 hour rate capacity (20HR) is
equivalent (80Ah) or greater, and per- formance rating (CCA) is equivalent (685A) or greater.
LC500h: Use a 12-volt battery that the case size is same as the previous one (LN3), 20 hour rate capacity (20HR) is
equivalent (70Ah) or greater, and perfor- mance rating (CCA) is equivalent
(600A) or greater. • If the sizes differ, the 12-volt battery can-not be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not used is a short time, the 12-volt battery
may discharge and engine <hybrid sys- tem> may not be able to start.
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●After exchanging, firmly attach the fol-lowing items to the exhaust hole of the 12-
volt battery. • Use the exhaust hose that was attached to the 12-volt battery before exchanging.
• Use the exhaust hole plug included with the 12-volt battery exchanged or the one installed on the battery prior to the
exchange. (Depending on the 12-volt battery to be exchanged, the exhaust hole may be plugged.)
