conditions, heavy traffic areas, urban
areas, desert areas or dirt roads.
Refer to your Owner’s Manual for
service details.
Differential Oil
Check for correct oil level and
inspect each differential component
for signs of leakage. If you discover
any leakage, have it repaired
immediately by a qualified technician.
Refer to your Owner’s Manual for
fluid specifications.
Drive Belt
Inspect for cracks, excessive wear
and oiliness. Check the belt tension
and adjust if necessary. Replace the
belts if they are damaged. Drive Shaft

A qualified technician should perform
this operation.

MAINTENANCE Scheduled Maintenance Log70 Engine Coolant
When inspecting, visually check
the level of the engine coolant on the
see-through reservoir. 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.
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.
n ote: Initial replacement of engine
coolant is at 120 months/100,000
miles. Replace every 60 months/
50,000 miles thereafter. 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.
n ote: 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.

MAINTENANCE Scheduled Maintenance Log72 Timing Chain
The timing chain requires no
periodic inspection.
Tire Rotation
See your Owner’s Manual for tire
rotation requirements. Check tire
pressure and check tires for damage
and uneven wear. If the vehicle is
equipped with a spare tire, check the
condition and pressure of the spare.
Tire-Pressure Warning Sensors
A tire-pressure sensor is mounted on
each full-size wheel. These sensors
do not require periodic maintenance.
When a sensor’s long-life lithium bat -
tery becomes discharged, the battery
should be replaced by a qualified
technician following procedures in
Lexus service and repair publications.
Transfer Case Oil
Check for correct oil level and
inspect each component for signs of
leakage. If you discover any leakage,
have it repaired immediately by a
qualified technician. For correct oil,
refer to your Owner’s Manual . Transmission
The transmission and transmission
fluid are a completely sealed unit.
Therefore, periodic checks and
replacement of the transmission
