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.
