Solid, stationary, unpainted metallic point away from the exclusive jump starting
terminal and any moving parts as shown in the illustration
5 Start the engine of the second vehi-
cle. Increase the engine speed
slightly and maintain at that level for
approximately 5 minutes to
recharge the 12-volt battery of your
vehicle.
6 Open and close any of the door of
your vehicle with the engine switch
off.
7 Maintain the engine speed of the
second vehicle and start the engine
of your vehicle by
turning the engine switch switch> to IGNITION ON mode
.
8 Once the vehicle’s engine system> has started, remove the
jumper cables in the exact reverse
order from which they were con-
nected.
9 Close the exclusive jump starting
terminal cover, and reinstall the fuse
box cover to tits original position.
Once the engine starts, have the vehicle inspected at any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer as soon as possible.

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
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 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 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 off. If you are unsure what mode the engine
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 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.)
