When removing the battery terminals
■
When the battery terminals are removed,
the information stored in the ECU is
cleared. Before removing 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
Immediately after replacing the battery,
●
fully open or close the soft top roof, as the
luggage cover may be half-opened.
of the side window
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 disconnecting the bat-
tery, turn the engine switch off.
If you are unsure what mode the engine
switch was in before the battery dis-
charged, be especially careful when
reconnecting the battery.
If the 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.310)
When replacing the battery
■
Use a Central Degassing type battery
●
(European Regulations).
●
Use a battery that the case size is same as
the previous one (LN4), 20 hour rate
capacity (20HR) is equivalent (80Ah) or
greater, and performance rating (CCA)
is equivalent (685A) 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 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 exchanging, firmly attach the fol-
●
lowing items to the exhaust hole of the
battery.
• Use the exhaust hose that was attached
to the battery before exchanging.
• Use the exhaust hole plug included with
the battery exchanged or the one
