or noncompliance caused by lack
of maintenance is not covered by
this warranty.
When maintenance and repairs
are paid for by you, these services
may be performed by you or by

EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
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.
Exhaust Pipes and Mountings
Visually inspect the exhaust pipes,
muffler and hangers for cracks,
deterioration and damage. Start the
engine and listen carefully for any
exhaust leakage. Tighten connections
and replace parts as necessary.
Fuel Lines and Connections,
Fuel Tank Band and Fuel Tank
Vapor Vent System Hoses
Visually inspect for corrosion,
damage, cracks, and loose or leaking
connections. Tighten connections
and replace parts as necessary.
Fuel Tank Cap Gasket
Visually inspect for cracks,
deterio ration and damage
and replace if necessary.
Nuts and Bolts on Chassis
Check that tightness of the seat-
mounting bolts and front/rear
suspension-member retaining bolts
matches torque measurements
specified in the Repair Manual.
Rack-and-Pinion Assembly
Inspect the rack-and-pinion assembly
for signs of leakage, damage and
loose electrical connections. Tighten
connections and if you discover any
leakage or damage, have it repaired
immediately by a qualified technician.
Road Test
While driving the vehicle, check
for proper operation of engine,
transmission, brakes and steering.
Also check the parking brake, and
check for ab normal noise or vibration
from any part of the vehicle.

EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as origi-
nally equipped. A qualified technician
should perform this operation.
Steering Linkage and Boots
With the vehicle stopped, check for
excessive freeplay in the steering wheel.
Inspect the linkage for bending and
damage and the dust boots for deterio-
ration, cracks and damage. Replace any
damaged parts. A qualified technician
should perform these operations.
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 battery
becomes discharged, the battery should
be replaced by a qualified technician
following procedures in Lexus service
and repair publications.
Transmission/Transfer Case
Inspect transmission/transfer case for
signs of leakage. If you discover any
leakage, have it repaired immediately
by a qualified technician.
Note: The trans mission/transfer case
and transmission fluid are a completely
sealed unit. Therefore, periodic checks
and replacement of the transmission
fluid are not required, and there is no
dipstick on the transmission. Any repairs
that require adding or replacing fluid
should be performed by a qualified
technician following procedures in
Lexus service and repair publications.
Wiper Blades
The wiper blades should not show
any signs of cracking, splitting, wear,
contamination or deformation. The
wiper blades should clear the wind-
shield without streaking or skipping.
