■
Starting the engine <hybrid system>
when the 12-volt battery is discharged
The engine <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 engine <hybrid system> 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 your Lexus
dealer.
●
Some systems may require initialization.
(
■
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 engine <hybrid system>
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 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 engine <hybrid system> 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 <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 engine switch <power switch> off.
If you are unsure what mode the engine
switch <power 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. (
■
When replacing the 12-volt battery
●
Use a Central Degassing type 12-volt
battery (European Regulations).
●
Type A
*1
: 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.
Type B
*2
: 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 <hybrid sys-
tem> 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.)
