450 7-2. Steps to take in an emergency
LS500h_OM_OM50F42U_(U) 6 Open and close any of the doors of
your vehicle with the power switch
off.
7 Maintain the engine speed of the
second vehicle and start the hybrid
system of your vehicle by turning
the power switch to ON mode.
8 Make sure the “READY” indicator
comes on. If the indicator does not
come on, contact your Lexus
dealer.
9 Once the hybrid system has
started, remove the jumper cables
in the exact reverse order from
which they were connected.
10 Close the exclusive jump starting
terminal cover and install the fuse
box cover and en gine compart-
ment cover.
Once the hybrid system starts, have
the vehicle inspected at your Lexus
dealer as soon as possible. ■
Starting the hybrid system when the
12-volt battery is discharged
The hybrid system cannot be started by
push-starting. ■
To prevent 12-volt battery discharge●
Turn off the headlights and the audio sys-
tem while the hybrid system is off.
●
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 your Lexus
dealer.
●
Some systems may require initialization. ( → P.495)■
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 your
Lexus dealer. ■
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 hybrid system may be
unable to start. (The 12-volt battery
recharges automatically while the hybrid
system is operating.) ■
When recharging or replacing the
12-volt battery ●
In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
12-volt battery is discharged. Use the
wireless remote control or the mechani-
cal key to lock or unlock the doors. ●
The hybrid system may not start on the
first attempt after the 12-volt battery has
recharged but will start normally after the
second attempt. This is not a malfunction. ●
The 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 power switch
off.
If you are unsure what mode the power
switch was in before the 12-volt battery
discharged, be especially careful when
reconnecting the 12-volt battery.
■
When replacing the 12-volt battery
●
Use a Central Degassing type 12-volt
battery (European Regulations).
●
Use a 12-volt battery with the same case
size as the previous 12-volt battery and an
epuivalent 20 hour rate capacity (20HR)
or greater.

4517-2. Steps to take in an emergency
LS500h_OM_OM50F42U_(U) 7
When trouble arises • 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 the hybrid system
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 replacing, firmly attach the follow-
ing items to the exhaust hole of the
12-volt battery.
• Use the exhaust hose that was attached
to the 12-volt battery before replacing
and confirm that it is firmly connected to
the hole section of the vehicle.
• Use the exhaust hole plug included with
the 12-volt battery replaced or the one
installed on the 12-volt battery prior to
the replacement. (Depending on the
12-volt battery to be replaced, the
exhaust hole may be plugged.)

C 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 unintentiona lly in contact with
any other than the intended terminal. ●
Do not allow the other end of the
jumper cable connected to the “+” ter-
minal to come into contact with any
other parts or meta l 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.
■
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 battery fluids
(acid) to come into contact with skin,
clothing or the vehicle body.
●
Do not lean over the 12-volt battery.
