Engine and Inverter Coolants
When inspecting, visually check
the level of the engine and inverter
coolants on the see-through
reservoirs. Add coolant as necessary.
When replacing, drain the cooling
system and refill with coolant. Always
use Genuine Toyota Super Long-Life
Coolant or similar high-quality
non-silicate, non-amine, non-nitrate,
non-borate ethylene-glycol coolant
with long-life hybrid organic acid
technology (i.e., a combination of
low phosphates and organic acids).
A qualified technician should perform
these operations. Please refer to the
important safety precautions on the
inside front cover of this booklet.
Check the radiator and condenser
for blockage by leaves, dirt or insects
and clean if necessary. Also check
the hose connections for corrosion
and condition of installation.
Note: Initial replacement of engine
coolant is at 120 months/100,000
miles. Replace every 60 months/
50,000 miles thereafter. Initial
replacement of inverter coolant is at
180 months/150,000 miles. Replace
every 60 months/50,000 miles
thereafter.

Scheduled Maintenance Log
Engine Oil and Oil Filter
Replace the oil filter and drain and
refill the engine oil at specified
intervals. SAE 0W-20 oil is the best
choice for good fuel economy and
good starting in cold weather. If SAE
0W-20 is not available, SAE 5W-20
may be used; however, it must be
replaced with SAE 0W-20 at the next
oil change. See your Lexus dealer for
oil specifically formulated for your
vehicle's engine.
Your vehicle is equipped with a
replaceable oil-filter element and
oil-filter cap O-ring; replace both
at each oil change. For instructions
on how to reset the reminder light,
refer to your Owner's Manual.
Note: If you do the majority of your
driving under any of the special
operating conditions indicated on
page 44, you should replace the
engine oil and oil filter every six
months or 5,000 miles, regardless
of the oil used or the certification of
the vehicle.
