When the battery is removed or dis-
charged●
Information stored in the ECU is cleared.
When the battery is depleted, have the
vehicle inspected at your Lexus dealer.●
Some systems may require initialization.
(  P.481)■
When removing the battery terminals
When the battery terminals are removed,
the information stored in the ECU is
cleared. Before removi ng the battery termi-
nals, contact your Lexus dealer. ■
Charging the battery
The electricity stored in the battery will dis-
charge gradually even when the vehicle is
not in use, due to natural discharge and the
draining effects of certain electrical appli-
ances. If the vehicle is left for a long time,
the battery may discharge, and the engine
may be unable to start. (The battery
recharges automatically during driving.) ■
When recharging or replacing the bat-
tery●
In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
battery is discharged. Use the wireless
remote control or the mechanical key to
lock or unlock the doors.●
The engine may not start on the first
attempt after the battery has recharged
but will start normally after the second
attempt. This is not a malfunction.●
The engine switch mode is memorized by
the vehicle. When the battery is recon-
nected, the system will return to the
mode it was in before the battery was dis-
charged. Before di sconnecting the bat-
tery, turn the engine switch off.
If you are unsure what mode the engine
switch was in befo re the battery dis-
charged, be especially careful when
reconnecting the battery.
■
When replacing the battery
●
Use a Central Degassing type battery
(European Regulations). ●
Use a battery with the same case size as
the previous battery and an equivalent
20 hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot 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 battery may dis-
charge and the engine may not be able to
start. ●
Use a battery with a handle. If a battery
without a handle is used, removal is more
difficult. ●
After replacing, firm ly attach the follow-
ing items to the exhaust hole of the bat-
tery.
• Use the exhaust hose that was attached
to the battery before replacing and con-
firm that it is firmly connected to the hole
section of the vehicle.
• Use the exhaust hole plug included with
the battery replaced or the one installed
on the battery prior to the replacement.
(Depending on the battery to be
replaced, the exhaust hole may be
plugged.)
