EXPLANATION OF MAINTENANCE ITEMS

MAINTENANCE
Scheduled Maintenance Log69
Brake Pads, Calipers and Rotors
Check brake pads and rotors for
excessive wear; check brake rotors
for runout. Check brake calipers for
fluid leakage. A qualified technician
should perform these inspections.
Differential Oil
Check for correct oil level and
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 Manualfor 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
Re-torque the flange nuts and bolts.
A qualified technician should perform
this operation.
Driver’s Floor Mat
•Only use the driver’s floor mat
designed specifically for the
model and model year of your
vehicle, such as Lexus Genuine
floor mats.
•Always properly secure the dri-
ver’s floor mat using the retaining
hooks.
•Never install another floor mat
on top of the existing driver’s
floor mat.
•Never install the driver’s floor
mat upside down.
Engine Air Filter
Check for excessive dirt, damage and
oiliness. Replace if necessary.

Engine Coolant
When inspecting, visually check
the level of the engine coolant 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 Long-Life Coolant or
similar high-quality non-silicate,
nonamine, 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.
Note: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 inter-
vals. 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. 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 oper-
ating 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 connec-
tions and replace parts as necessary.

EXPLANATION OF MAINTENANCE ITEMS

MAINTENANCE
Scheduled Maintenance Log71
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-
sion-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, transmis-
sion, brakes and steering. Also check
the parking brake, and check for
abnormal noise or vibration from
any part of the vehicle.
Spark Plugs
Replace at specified interval. Install
new plugs of the same type as origi-
nally equipped (see your Owner’s
Manual). A qualified technician should
perform this operation. To ensure
optimum engine performance,
replace only with Denso FK20HR11
plugs or equivalent.
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
deterioration, cracks and damage.
Replace any damaged parts. A quali-
fied technician should perform these
operations.
