MAINTENANCE42 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 inspection
procedures.
Every 30 Days At least once every 30 days, perform
these inspections:
• Check engine oil level using
the dipstick
• Visually check engine coolant
level on the see - t hrough reservoir
• Visually check brake fluid level
on the see-through reservoir
• Visually check condition
of battery
• Check level of windshield
washer fluid
• Check tire pressure
• Check tires for damage
and wear
• Check installation of driver’s
floor mat After a Car Wash • Check installation of driver’s
floor mat
After Off-Road Driving Whenever you drive off-road through
deep sand, mud or water, perform
these inspections daily:
• Check axle shaft boots
• Check ball joints and dust covers
• Check brake lines and hoses
• Check brake pads/rotors and
parking brake linings/drums
• Check differential oil
• Check engine air filter
• Check nuts and bolts on chassis
• Check steering linkage
and boots
• Check transfer case oil
(AWD models)
• Check transmission for
signs of leakage

MAINTENANCE Scheduled Maintenance Log70 Engine Coolant
When inspecting, visually check
the level of the engine coolant 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). 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.
n ote: 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
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.
n ote: 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.
