CHECKING THE ENGINE OIL LEVEL
62X001e
With the engine at operating temperature and turned off,
check the oil level on the dipstick.
1. To get a correct reading, the vehicle should be on level
ground. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it
clean.
3. Standing up on the left side of the vehicle, reinsert the
dipstick in the direction so that the “ENGINE OIL” on top should
be read correctly and push it in as far as it will go, or the reading
will not be correct.

4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the full line (
5 ) and the
low line ( 4 ), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.

62X002c
If the oil level is below or only slightly above the low line,
add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low and full on the dipstick is indicated
as follows.
1.5 L (1.6 qt., 1.3 lmp. qt.)
For the engine oil capacity, see “Specifications” on page 402.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
NOTICE
 Be careful not to spill engine oil on the vehicle
components.
 Avoid overfilling, or the engine could be damaged.
 Check the oil level on the dipstick once again after
adding the oil.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use
Lexus approved “Toyota Genuine Motor Oil” or equivalent to
satisfy the following grade and viscosity.
Oil grade: ILSAC multigrade engine oil.
Recommended viscosity: SAE 5W− 30
62sa08
Outside temperature
SAE 5W30 is the best choice, for good fuel economy, and
good starting in cold weather.
If SAE 5W30 oil is not available, SAE 10W30 oil may be
used. However, it should be replaced with SAE 5W30 at
the next oil change.
Oil identification mark
g62035
The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is added to some oil
containers to help you select the oil you should use.
To ensure excellent lubrication performance for your engine,
“Toyota Genuine Motor Oil” is available, which has been
specifically tested and approved for all Lexus engines.
Please contact your Lexus deal er for further details about
“Toyota Genuine Motor Oil”.

CHECKING THE ENGINE COOLANTLEVEL
62X003d
 1Radiator cap 2“FULL” line 3“LOW” line
Look at the seethrough coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the“FULL” and “LOW” lines on the reservoir. If
the level is low, add the coolant. (For the coolant type, see
“Coolant type selection” described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the “LOW”
line, add coolant. Bring the level up to the “FULL” line. If the coolant level drops within a short time after replenishing,
there
may be a leak in the system. V isually check the radiator,
hoses, engine coolant filler cap, radiator cap and drain cock
and water pump.
If you can find no leak, have your Lexus dealer test the radiator
cap pressure and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.

ENGINE

Coolant type selection
Use of improper coolants may damage your engine cooling
system.
Only use “Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non−silicate, non −amine,
non− nitrite, and non −borate coolant with long −life hybrid
organic acid technology. (Coolant with long −life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
For the U.S.A.—“Toyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about –35 C (–31F).
For Canada—“Toyota Super Long Life Coolant” is a mixture of
55% coolant and 45% deionized water. This coolant provides
protection down to about –42 C (–44F).
NOTICE
Do not use plain water alone.
Lexus recommends “Toyota Super Long Life Coolant”, which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper
usage. “Toyota Super Long Life Coolant” is formulated with
long−life hybrid organic acid technology and has been
specifically designed to avoid engine cooling system
malfunction on Lexus vehicles.
Please contact your Lexus dealer for further details.
CHECKING THE RADIATOR AND CONDENSER
If either of the above parts are extremely dirty or you are not
sure of their condition, take your vehicle to a Lexus dealer.
CAUTION
To prevent burning yourself, be careful not to touch the
radiator or condenser when the engine is hot.
NOTICE
To prevent damage to the radiator and condenser, do
not perform the work by yourself.

CHECKING BRAKE FLUID
63X001b
To check the fluid level, simply look at the seethrough
reservoir. The level should be between the “MAX” and
“MIN” lines on the tank.
It is normal for the brake fluid level to go down slightly as the
brake pads wear or when the fluid level in the accumulator is
high.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE J1703
brake fluid to the brake reservoir.
Refilling brake fluid:
1. Turn the ignition switch off.
2. Depress the brake pedal more than 40 times.
3. Remove the reservoir cap by hand. Add brake fluid up to the
“MAX” line. If you do not follow the procedure above, the reservoir may
overflow.
Use only newly opened brake fluid. Once opened, brake fluid
absorbs
moisture from the air, and excess moisture can cause
a dangerous loss of braking efficiency.
CAUTION
Take care when filling the brake fluid reservoir because
brake fluid can harm your hands or eyes. If fluid gets on
your hands or in your eyes, flush the affected area with
clean water immediately. If you still feel uncomfortable
with your hands or eyes, go to the doctor.
NOTICE
If you spill some of the fluid, be sure to wipe it off to
prevent it from damaging the parts or paintwork.

CHECKING POWER STEERINGFLUID
63X002a
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III .
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60 C − 80C or 140F − 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C − 30C
or 50F − 85F) if the engine has not been run for about five
hours.
63X003a
 1 If hot O.K. 2If hot add 3If cold O.K.
4If cold add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the “COLD” range. Similarly,
if it is hot, the fluid level should be in the “HOT” range. If th\
e
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.
CAUTION
The reservoir may be hot so be careful not to burn
yourself.
