Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line. (→P. 5 8 7 )
nCoolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -31°F [-35°C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45%
deionized water. (Minimum temperature: -44°F [-42°C])
For more details about coolant, contact your Lexus dealer.

Introduction
GENERAL MAINTENANCE AND REGULAR USE
MAINTENANCE
42
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.
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-through
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 fluid

EXPLANATION OF MAINTENANCE ITEMS
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
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.
