Exclusive jump starting terminal (your vehicle)
Positive (+) battery terminal (second vehicle)
Negative (-) battery terminal (second vehicle)
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.
■Starting the engine when the 12-volt battery is discharged
The engine cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio sys-tem while the engine is
stopped.
●Turn off any unnecessary electrical com-

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.)

WARNING
■When removing the 12-volt battery
terminals
Always remove the negative (-) terminal first. If the positive (+) terminal contacts any metal in the surrounding area when
the positive (+) terminal is removed, a spark may occur, leading to a fire in addi-tion to electrical shocks and death or
serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12- volt battery:
●Make sure each jumper cable is con-nected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.

B
C
●Do not allow the other end of the jumper cable connected to the “+” ter-
minal to come into contact with any other parts or metal surfaces in the area, such as brackets or unpainted
metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with each other.
●Do not smoke, use matches, cigarette
lighters or allow open flame near the 12-volt battery.
●If the 12-volt battery fluid level is exces-sively low ( P.327), do not use the
12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead com-
pounds. Observe the following precau- tions when handling the 12-volt battery:
●When working with the 12-volt battery, always wear safety glasses and take
care not to allow any 12-volt battery fluids (acid) to come into contact with
skin, clothing or the vehicle body.
●Do not lean over the 12-volt battery.
●In the event that 12-volt battery fluid comes into contact with the skin or eyes, immediately wash the affected
area with water and seek medical attention.Place a wet sponge or cloth over the
affected area until medical attention can be received.
●Always wash your hands after handling the 12-volt battery support, terminals,
and other battery-related parts.
●Do not allow children near the 12-volt battery.

7-2. Steps to take in an emergency
1Stop the vehicle in a safe place and
turn off the air conditioning system,
and then stop the engine.
2 If you see steam:
Carefully lift the hood after the
steam subsides.
If you do not see steam:
Carefully lift the hood.
3 After the engine has cooled down
sufficiently, inspect the hoses and
WARNING
■After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer as soon as possible. If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery to emit a
malodorous gas, which may be detri- mental to the health of passengers.
■When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the exchanged 12- volt battery. If not properly installed, gases (hydrogen) may leak into the vehi-
cle interior, and there is the possible dan- ger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-gled in the cooling fan or engine drive
belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt bat-tery from another vehicle in an emer-
gency. It cannot be used to jump start another vehicle.
If your vehi cle overheats
(LC500)
The following may indicate that
your vehicle is overheating.
 The engine coolant temperature
gauge ( P.88) is in the red zone
or a loss of engine power is expe-
rienced. (For example, the vehicle
speed does not increase.)
 “Engine Coolant Temp High” is
shown on the multi-information
display.
 Steam comes out from under the
hood.
