Scheduled Maintenance Log
Battery: 12-Volt
(Auxiliary Battery)
The original­equipment 12­volt
battery, located on the left side of
the trunk compartment, is a sealed,
maintenance­free special­application
battery that is different from a
conventional automotive battery.
Replacement batteries are available
from your Lexus dealership.
Battery: Hybrid
(Traction Battery)
The hybrid battery is a NiMH (nickel
metal hydride) compact, high­output
battery. This battery does not require
regular maintenance. However, if the
vehicle is parked for a long time, the
hybrid battery will discharge gradually.
To keep the hybrid battery in good
condition, drive the vehicle at least
once every several months for at least
30 minutes or 10 miles. If the hybrid
battery becomes fully discharged and
the vehicle will not start even with
a jump­start to the 12­volt battery,
contact your Lexus dealership.
Any repairs to the hybrid battery or
hybrid system should be performed
by a qualified technician following
procedures in Lexus service and repair
publications. Please refer to the
important safety precautions on the
inside front cover of this booklet.
