of your Owner's Manual.

clamps for cracks, deterioration
and damage. Replace any damaged
parts and, if necessary, repack
the grease. A qualified technician
should perform these operations.

68 Scheduled Maintenance Log
Battery: 12-Volt (Auxiliary
Battery)
The original-equipment 12-volt
battery, located on the left side of
the cargo compartment, is a sealed,
maintenance-free special-application
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, high-output
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 jump-start
to the 12-volt 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.
