In some situations, the master warning light and warning buzzer may not oper-
ate as specified. In this case, follow the instructions displayed in the warning

QWarning messages
The warning messages explained below
may differ from the actual messages
according to operation conditions and vehi-
cle specifications.
QWarning buzzer
In some cases, the buzzer may not be heard
due to being in a noisy location or audio
sound.
QIf “Engine Oil Level Low Add or
Replace” is displayed
The engine oil level is low. Check the level
of the engine oil, and add if necessary.
This message may appear if the vehicle is
stopped on a slope. Move the vehicle to a
level surface and check to see if the mes-
sage disappears.
QIf “Hybrid System Stopped Steering
Power Low” is displayed
This message is displayed if the hybrid sys-
tem is stopped while driving.
When steering wheel operations are
heavier than usual, grip the steering wheel
firmly and operate it using more force than
usual.
QIf “Hybrid system overheated Output
power reduced” is displayed
This message may be displayed when driv-
ing under severe operating conditions. (For
example, when driving up a long steep hill.)
Handling method:  P.396
QIf “Traction Battery Needs to be Pro-
tected Refrain From the Use of N Posi-
tion” is displayed
This message may be displayed when the
shift lever is in N.
As the hybrid battery (traction battery) can
not be charged when the shift lever is in N,
shift the shift lever to P when the vehicle is
stopped.
QIf “Traction Battery Needs to be Pro-
tected Shift into P to Restart” is dis-
played
This message is displayed when the hybrid
battery (traction battery) charge has
become extremely low because the shift
lever has been left in N for a certain amount
of time.
When operating the vehicle, shift to P and
restart the hybrid system.
QIf “Shift to P Before Exiting Vehicle” is
displayed
Message is displayed when the driver’s
door is opened without turning the power

When trouble arises
6Open 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 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.
