■

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.

(

P.403)

■

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. (

P.330)

■

When replacing the 12-volt battery

●

Use a Central Degassing type 12-volt

battery (European Regulations).

●

Type A

: 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.
