In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks and
visual inspections. The recommended
guidelines for inspections are listed
below. Please refer to the “Mainte
nance” section of the Owner’s Manual
for a detailed description of inspec
tion procedures.
When Refueling
When refueling, perform these
inspections:
•Check engine oil level using
the dipstick
• Visually check engine coolant
level on the seethrough
reservoir (under cover)
• Visually check brake fluid level
on the seethrough reservoir
• Visually check power steering
fluid level on the seethrough
reservoir (under cover)
• Visually check condition of
battery (under cover)
• Check level of windshield
washer fluid
Every 30 Days
At least once every 30 days, perform
these inspections:
•Check tire pressure
• Check tires for damage
and wear
When Cleaning the Interior
•Remove dirt and dust with a
vacuum cleaner. Wipe dirty sur
faces with a soft cloth dampened
with warm water.
• When cleaning carpet or cloth
interior, remove dirt and dust
with a vacuum cleaner. Apply
a foamingtype carpet cleaner
with a sponge or brush, allowing
cleaner to work for a few min
utes to loosen dirt. Continue by
rubbing carpet or cloth interior
in a circular motion. Wipe off any
excess cleaner with a clean cloth.
If any dirt remains, repeat process.
Best results are obtained by
keeping carpet and cloth interior
as dry as possible.
• When cleaning leather interior,

Brake Pads, Calipers and Rotors
Check brake pads and rotors for
excessive wear; check brake rotors
for runout. Check brake calipers for
fluid leakage. Check the parking
brake linings (shoes) and drums for
scoring, burning, fluid leakage, broken
parts and excessive wear. Some mod
els are equipped with directional
rotors. When servicing these rotors,
reinstall at same location. A qualified
technician should perform these
operations. See inside front cover
for additional brake information.
Differential Oil
Inspect each differential component
for signs of leakage. If you discover
any leakage, have it repaired immedi
ately by a qualified technician. Refer
to your Owner’s Manual
for fluid
specifications. For ISF, replace rear
differential oil at specified intervals.
Drive Belt
Inspect for cracks, excessive wear
and oiliness. Check the belt tension
and adjust if necessary. Replace the
belt if it is damaged. Engine Air Filter
Check for damage, excessive wear
and oiliness. Replace if necessary.
Engine Coolant
When inspecting, visually check
the engine coolant level on the see
through reservoir. Add coolant as
necessary. When replacing, drain
and flush the cooling system and refill
with coolant. Always use Genuine
Toyota Super LongLife Coolant or
similar highquality nonsilicate, non
amine, nonnitrate, nonborate ethyl
eneglycol coolant with longlife
hybrid organic acid technology (i.e.,
a combination of low phosphates and
organic acids). Check that the radia
tor is not blocked with leaves, dirt or
insects and clean if necessary. Also
check the hose connections for cor
rosion and condition of installation.
A qualified technician should perform
these operations.
Note: Initial replacement 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 inter
vals. For recommended oil grade
and viscosity, refer to your Owner’s
Manual . Some models are equipped
with a replaceable oilfilter element
and oilfilter cap Oring; replace both
at each oil change. For instructions on
how to reset the reminder light, refer
to your Owner’s Manual .
Engine Valve Clearance
(Sensory Inspection — IS F, SC)
Inspect for excessive lifter noise and
engine vibration and adjust if neces
sary. (All other models are equipped
with hydraulic valve lash adjusters that
require no periodic clearance inspec
tion or adjustment.)
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 connec
tions and replace parts as necessary.
Fuel Lines and Connections, Fuel
Tank Band and Fuel Tank Vapor
Vent System Hoses
Visually inspect for corrosion, dam
age, 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 suspen
sionmember retaining bolts matches
torque measurements specified in the
Repair Manual .
Power Steering Fluid
When inspecting, visually check the
power steering fluid level on the see
through reservoir. Add fluid as neces
sary. For fluid specifications, refer to
your Owner's 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
