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 discharge, and the EV
system may be unable to start.
(The 12-volt battery recharges automati-
cally while the EV system is operating.)
When replacing the 12-volt battery
■
●
Use 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 (345A) or
greater.
• If the sizes differ, the 12-volt battery can-
not be properly secured.
• If the 20 hour rate capacity of the
replacement battery is low, even if the
vehicle is used frequently, the 12-volt bat-
tery may discharge and EV system may
not be able to start.
For details, consult your Lexus dealer.
