EXPLANATION OF MAINTENANCE ITEMS

The following descriptions are provid-
ed to give you a better understanding

Please note that many maintenance
services should be performed only
by a qualified technician.
For further information on
maintenance services that you
can perform yourself, see the
maintenance sections of your

frequent replacement may be required

A qualified technician should perform

linkage ball joints for looseness and

Battery: 12-Volt (Auxiliary
Battery)
The original-equipment 12-volt bat-
tery is a sealed, maintenance-free
special-application battery that is dif-
ferent 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 gradual-
ly. 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, con-
tact your Lexus dealership.
