EXPLANATION OF MAINTENANCE ITEMS
MAINTENANCE
Scheduled Maintenance Log
Cabin Air Filter
Replace at specified intervals. More
frequent replacement may be required
when driving in dusty conditions,
heavy traffic areas, urban areas, desert
areas or dirt roads. Refer to your
Owner’s Manual for service details.
Differential Oil
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
belt if it is damaged.
Driver’s Floor Mat
•
Only use the driver’s floor mat
de signed specifically for the model
and model year of your vehicle,
such as Lexus Genuine floor mats.
• Always properly secure the
driver’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 engine coolant level 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). Check that the
radiator is not blocked with leaves,
dirt or insects and clean if necessary.
Also check the hose connection 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.
