When trouble arises
6Open and close any of the doors of
your vehicle with the power switch
off.

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 vehicle’s 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 reinstall the
fuse box cover to its original posi-
tion.
Once the hybrid system starts, have the
vehicle inspected at your Lexus dealer as
soon as possible.
QStarting the hybrid system when the 12-
volt battery is discharged
The hybrid system cannot be started by
push-starting.
QTo prevent 12-volt battery discharge
OTurn off the headlights and the audio sys-
tem while the hybrid system is stopped.
OTurn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.
QWhen the 12-volt battery is removed or
discharged
OInformation stored in the ECU is cleared.
When the 12-volt battery is depleted,
have the vehicle inspected at your Lexus
dealer.
OSome systems may require initialization.
(  P.433)
QWhen 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.
QCharging 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.)
QWhen recharging or replacing the 12-
volt battery
OIn 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.
OThe 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.
OThe 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.
QWhen replacing the 12-volt battery
OUse a 12-volt battery that conforms to
European regulations.
OUse a 12-volt battery that the case size is
same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent
(60Ah) or greater, and performance rat-
ing (CCA) is equivalent (563A) or
greater.
